Question: Formulate possible technical solutions to address the student-prepared design specification.

Introduction

Design solution refers to the method which an engineer follows for producing the physical form of a specified product or process following its determined specifications so that the defined aim and objective of the client or associated stakeholders might be met appropriately(Renzi, et al., 2017). The study is an extended version of assessment 1 in which a design brief and specification for a smart robotic assistance product are proposed to support the considered FMCG (Fast Moving Consumer Goods) retailing company in its inventory management process. With the support of research work, initially, the specifications which are proposed and finalized in the previous assessment for the new engineering product are detailed and these are eventually used to identify and analyze possible solutions following which the designed product can be developed.

Further, the opinions of different sources of information like journals, books, and blogs regarding the competitiveness of different solutions against the design specification of the proposed robotic productare analyzed and this is eventually used to detect which could be best for developing the robotic product. Further, the manufacturing process of the finalized design solution is identified and analyzed along with understanding its compliance in the context of risk, regulation, and health and safety policies. Besides this, a critical analysis of the advantages and disadvantages of finalized design is made along with highlighting the future consideration for improving its limitations and this is eventually used to conclude the work.

Overview of Design Specification
Design specification refers to the functional, physical, and other non-functional criteria which are supposed to be performed by the final designed product after its development so that determined associated aim and objective might be fulfilled appropriately(Kwong, et al., 2016). In other words, design specification is an organizational document that details the entire parameters like quality, performance, dimension, and maintenance of a proposed product or process so that an appropriate approach might be followed during the designing and production phase for addressing the defined research problem appropriately(Menold, et al., 2017).

The elements which are considered for finalizing the specifications of the proposed smart robotic product for inventory management purposes are listed as follows-
• Performance
• Operational temperature level
• Material to be used in the aesthetic of the proposed product
• Source of power
• Maintenance requirements and scheduling
• Health and safety level

Performance

In the context of performance metrics, it is finalized by the FMCG retailing company that the smart robotic product should work with minimum consumption of electricity, and its transmission motor should be developed following the principle of clean energy. Apart from it, the proposed product should be developed with the concept of a hybrid power source principle so that dependency on the conventional source of energy like electricity might be reduced by empowering its capability to get charged itself using sun rays. Besides this, the robotic assistance should be capable of capturing, reading, recording, and communicating every aspect of inventory appropriately so that possibility of any error like in the case of a human-based job might be minimized(Sharkawy, 2021). The robotic product should be efficient in using the management information system of the FMCG company so that it might communicate and report the real-time status of inventory procured or delivered or available to the higher authority in real-time. Further, it is expected that the engineering inventory management automation product should be efficient in conducting allocated work continuously for 5 days a week without any charging need. Apart from it, the external and internal body of the robotic assistant should be durable enough so that it might handle the carrying process of inventory from vehicle to warehouse or vice-versa without any loading or fragment issues. The wiring system should be designed in an insulated format within the body of the robotic so that possibility of any short-circuits might be curbed in advance for reducing any financial and operational losses(Rhiat, et al., 2022).

Further, it is expected that the robotic assistant should be efficient in analyzing the inflow and outflow trend of inventory appropriately so that it might assist management in taking informed decisions for optimizing inventory and operating costs. Further, the power system of the proposed engineering product should be interlinked with its neural or programming system so that in case of any power discharge issue, it might automatically take necessary action like connecting to the power source and using sun ray for mitigating any functional off issue(Paul, et al., 2019).

Operational Temperature
The proposed robotic product should be efficient in conducting programmed inventory management work in all weather condition conditions whether the temperature is 16 degrees Celsius or 57 degree Celsius. In other words, the operational temperature level of the engineering product should be in the range of 16 degrees Celsius to 57 degrees Celsius. Apart from it, the internal wiring system and power consumption efficiency of the robotic product should not vary even partially in case of the operational temperature either go to the minimum level or maximum level.

Material to be Used
For providing a higher degree of durability to the proposed robotic product, its internal and external aesthetic should be made of steel, cast iron, and titanium so that the engineering product should not face any weight-lifting issues while handling necessary inventory in the warehouse of the FMCG retailing company. For providing long-lasting power to the robot with instant charging trait, Li-Po (Lithium Polymer Batteries) should be used within the engineered product as the batteries are light in weight with higher power holding capacity(Xiong, et al., 2021). Further, the voltage rating of the battery which will be used in the robotic product should be in the increment of more than 3.7 voltage. Apart from it, solar cells with higher power-holding capacity should be integrated within the chassis of the proposed smart robot so that it might be empowered to generate the required amount of power with the help of the photovoltaic effect(Wang, 2017).

Power Source to be Used
The proposed smart robotic should be developed the principle of hybrid energy so that it might use both conventional sources of energy like electricity and sun rays for meeting a respective power-related need as per real-time scenarios without any functional stoppage issue.

Maintenance
The robotic product should be designed with a self-rebooting ability so that every 5 days, it might fix any technical or power charging issue automatically using the reboot option. Apart from it, the engineered product should need only scheduled maintenance once a year only for renewing or fixing any programming or power source, or aesthetic problems.

Safety
Since the smart robotic product is supposed to interact with the operational, supply chain employees and suppliers of the entityduring the inventory management process due to which it should act as per the perspective of human beings in all conditions so that any health and safety risk might be curbed(Kalinov, et al., 2021). The engineered product is smart enough to adjust its functionality as per the sensitivity of operational situations like fire and these traits make it comparatively safer for the surrounding human beings.

Ergonomic
The smart robotic product should be easy to disassemble and assemble so that it might be ported by the administration of the FMCG company to other branches as per need of inventory management purposes without any extensive supply chain costing issue. Apart from it, the engineered product should be easy to operate so that it might be stopped or adjusted, or programmed by the team of the entity as per the requirement of the business(Passow & Passow, 2017).

Target Users
The target users for the smart robotic product are the suppliers, supply chain team, and employees of the FMCG retailing company as they are the stakeholders who will communicate with the engineered product during the inventory management process.
Literature Review on the Possible Solutions Set by the Design Specification

Question: Prepare an industry-standard engineering technical design report.

Concept of Design Specification
Design specification is the collection of design criteria including the details of functional and non-functional parameters like power consumption and operating temperature which are followed and considered by the engineers while initiating the designing and production process of a targeted product(Schleich, et al., 2017). As per the principle of project and engineering management, for developing a competitive kind of product or process for an entity, it is necessary to understand the problem and needs of the client so that corrective designing-related measures might be taken to curb any variance in need fulfillment(Alvarenga, et al., 2019). In the context of understanding the problem and need of the client about the product or process, design specification plays a significant role for engineers during the designing process as it helps what quality and functional constraints, they have to follow while designing the product.

With the assistance of design specification, it becomes easy for engineers to have an in-depth understanding of the problem and needs of the client appropriately in the context of the proposed product and this eventually assists them to decide what design solutions they should take to meet the expectations appropriately(Zhang, 2018). For example, during the design specification section, it has been come to know that the team of the FMCG retailing company is interested to have environment-friendly and smart robotic assistance for its inventory management work like stock loading, unloading recording, and reporting. The outcome of the design specification document is that it has been easy for the engineers to get what design solutions should be adopted so that all the mentioned electrical, mechanical, and non-mechanical constraints might be met appropriately while developing and designing the proposed robotic product(Deininger, et al., 2017).

Preliminary Research on Methods of Development of a Product from its Design Specifications
As per the design theory of engineering management, for meeting the needs of a client in terms of a product without any variation in mentioned design specification, it is necessary for engineers or developers to analyze the competence of each possible method against the identified need(Hatchuel, et al., 2018). The significant method of design solution or development which the team of engineers might use for designing the proposed smart robotic product as per the design specifications of the FMCG Company is identified and illustrated as follows-

Structured Designing
Structured designing is the conventional designing solution method in which the identified problems of an organization are strategically segmented into different well-organized elements or phases so that appropriate designing actions might be taken for each sub-element appropriately(Wu, et al., 2021). In the case of the structured designing solution method, the entire design specification of an entity is tactfully broken into several structured constraints or components and these are eventually used to allocate the right roles to different team members so that possibility of any specification gap during the designing process might be curbed(Pongiglione & Calderini, 2016). The first and foremost advantage of the usage of a structured design solution or option is that it helps the management of a company to solve a larger problem at a very smaller scale so that the derived solution can fit in the larger image(Liu, et al., 2019).

Functional Designing
Functional designing is an augmented version of structured designing in which a system or engineered product which is supposed to be developed is split into several and potential subsystems or functions so that appropriate designing and development activities might be performed as per functional need(Buede & Miller, 2016).

In the case of functional designing option or solution, the entire system or specification is considered as the collection of functions or in a top-down perspective and this eventually assists in understanding how much-diversified functions are needed(Dinmukhamed, et al., 2021). The understanding of the diversification in the functions or specifications of a product or process helps in segmenting a team of engineers or developers accordingly so that the possibility of any functionality gap after the design process or development might not be faced within the developed product.

Concurrent Engineering
Concurrent engineering is an advanced engineering design option or solution in which the processes of product designing and development or manufacturing are executed simultaneously so that the accuracy in the functionality of each stage might be achieved in the action of the product appropriately(Knoll, et al., 2018).

In the case of concurrent engineering method or designing option, entire stages of product development or manufacturing are executed simultaneously as per the determined specifications rather than running each phase consecutively(Asyraf, et al., 2022). The first and foremost advantage of the concurrent designing option or solution is that it helps decrease the time of product development along with reducing the cost of productivity and optimizing overall productivity(Fischer, et al., 2018).

Question: Present to an audience a design solution based on the design report and evaluate the solution/ presentation.

Biomimetic Design Option or Solution
Biomimetic design option is an innovative design solution in which a design of a defined kind of product is developed with the support of natural processes, mechanisms, and materials along with mimicking the approaches available in nature so that the identified challenges might be met in a natural way(Du Plessis, et al., 2019). The foremost advantage of the innovative design option is that it helps in creating and developing a design of a product or process from the perspective of human beings by using only natural mechanisms and this eventually helps in increasing the suitability of the produced product in the targeted society.

Detail Research for the Possible Solutions for the Development of Proposed Product using its Design Specification and Recommendation
Preliminary research refers to the initial exploration which is conducted by researchers for finding out the potential information related to a research topic so that appropriate inferences might be utilized to make a final decision for addressing the research problem appropriately(Dannels, 2018). On the execution of preliminary research about the method of design solutions, the possible solutions for developing the proposed robotic product as per its design specification are illustrated as follows-

Structured Design Solution

Structured design is a conventional design solution that is based on the principle of the divide and conquers technique in which a bigger problem or specification is segmented or broken into structured elements so that the overall objective might be met appropriately by simplifying the difficulty level(Dinmukhamed, et al., 2021). In the case of a structured design solution, initially, the entire segmented components are arranged in a hierarchy format so that it might be understood which problem should be solved first so that the overall problem or specification might be met appropriately. The principle which is followed in the case of the structured design solution is based on a solution module in which every single problem is solved by segmenting it into smaller problems until the larger problem is fixed as per the determined specification. On the evaluation of the design specification mentioned by the management of the FMCG retailing company, it is found that there are 8 types of specifications or problems or constraints that are supposed to be met in the design of the proposed robotic products. Since the defined technical and non-technical specifications of the proposed robotic product are different in nature due to which it is not possible for the engineers to develop the engineered product or item without segmenting it into smaller ones (Fischer, et al., 2018). With the support of the structure design solution of option, it will be easy for the engineers to meet the different specifications of the robotic product at an even minute level and this will eventually assist it to get the innovative device ready for solving the inventory management problem accurately.

For example, as per the analysis of the technical specifications of the proposed robotic product, it is expected by the client that the robotic product should be efficient in performing the inventory management work 24*7 for up to 5 days without any additional charging needs. If the team of engineers has to develop a defined kind of robotic product along with meeting the performance-related specification or problem, then it will be easy by segmenting the entire problem into two different components including 24*7 working capability and 5 days power backup ability. In the context of the segmentation of the performance-related specification of the proposed robotic product, the principle of structured designing is found effective as it will not only assist in segmenting the respective problem into small components but it will also assist in meeting smaller decomposed needs appropriately(Faruk, et al., 2021). Apart from it, with the strategic usage of the structured design solution, it will be easy for the team of engineers to have an in-depth understanding of whether a particular kind of technical or non-technical specification is fulfilled appropriately or not. It means that the tactful deployment of a structure design solution will assist in cross-checking each functional aspect of the proposed smart robotic product as per the defined respective specification and this will eventually help in taking corrective action to meet an overall problem. The output of the overall design of the proposed robotic product is presented as follows in the form of breaking overall specifications into smaller ones and respective blueprints-

On the analysis of the modeling approach of the structured design solution, it is found that if the management of the FMCG retailing company will follow the design option for developing the proposed smart robotic product, then it will be successful in meeting each problem or specification appropriately. Apart from it, the structured design solution will play a significant part for the team of the engineer in solving and meeting each specification at a micro level and this will eventually assist in making the proposed robotic product efficient at both the larger and smaller scale. On the other hand, the primary limitation of the structured design solution is that a higher duration is needed for developing a design of a product as per the defined problem or specification and this might increase the possibility of meeting the stipulated deadline appropriately. It means that if the team of engineers will follow the principle of a structured design solution or option for developing the proposed robotic product, it will need maximum time for developing each specification within it and this might increase the possibility of deadline variation-related risk(Sharkawy, 2021). The risk of deadline variation might be solved by the team of engineers while designing the engineering product using the structured designing method by tactfully allocating and monitoring a deadline for each component and this will eventually assist in monitoring the overall project progress as well.

In the context of meeting the principle of the design-related industry standard "B7 7373", the simulated output of the proposed robotic assistance product developed following the principle of structured engineering is found competitive as it has focussed on keeping every safety-related specification met. It means that if the proposed robotic product will be developed following the principle of structured designing, then it will be easy for the engineers to reduce the possibility of any human safety-related risk appropriately. On the other hand, in the context of meeting overall costing and quality-related metrics of the industry standard "ACCESSFM", the design solution of the robotic product development following the principle of structure designing is marginally inefficient. In the case of a structured designing option, a bigger problem is solved by looking at overall smaller components due to which variance in functionality-related problem-solving accuracy is increased if a necessary closer approach is not but this can be fixed by taking a corrective approach. In short, the design solution of the proposed robotic product is efficient in meeting all the specifications and compliances of quality as well as safety-related industry standards along with a marginal variance in terms of functional accuracy.

Functional Design Solution

Functional design is an extended version of a structured designing solution in which several subsystems or functions are generated by splitting the entire system or specification so that every required specification or function might be met appropriately(Deininger, et al., 2017). The first and foremost benefit of a functional design solution is that by using the designing option, it will be easy for the team of engineers to develop the defined smart robotic product without having any variation in terms of functionality. For example, as per the identified specifications of the management of the FMCG retailing company about the proposed robotic product, it is expected that the engineering product should be efficient in performing both technical and non-technical work in all operational temperatures without having any battery backup issues. Using the functional design solution option, it will be easy for the engineers to meet the operational temperature-related specification of the robotic product appropriately as the designing option will assist in developing and cross-checking the respective dataflow in real time. It means that the functional designing option will play a significant part in ensuring the electrical and operational traits of the proposed robotic product appropriately with the strategic evaluation of respective inflow, outflow, and functionality in real-time and this will eventually assist in curbing the possibility of functional issues(Passow & Passow, 2017). The simulated outcome of the design solution of the proposed robotic product in the case of the functional design option is presented as follows and its effectiveness is illustrated further in the context of the industry standard-

On the analysis of the competitive trait of the functional designing option, it is found that the approach or solution is effective in designing the proposed robotic product appropriately in terms of technical functionality but the approach might provide some error in case of development of an aesthetic. It means that the structured designing option is better than the functional designing solution in terms of meeting all technical and non-technical specifications of the proposed robotic product. On the other hand, since the environmental safety guidelines related to functionality are appropriately handled in the case of functional designing options for the engineered product due to which its effectiveness is found in line with the industry standard of BS 7373. Apart from it, in terms of quality metric like costing, aesthetic and customer satisfaction and functionality of the industry standard, ACCESSFM, the functional designing solution is found appropriate but less efficient than the structured designing option as the earlier one focus more on data flow.

Concurrent Design Solution

Concurrent engineering or design solution is an advanced designing option in which the steps of product designing and development are accomplished simultaneously rather than performing each one separately(Menold, et al., 2017). If the team of engineers will follow the principle of the concurrent design process for the designing of the proposed robotic product, then it will be successful in testing the accuracy of each solution in the actual environment appropriately. For example, as per the mentioned specifications, it is expected that the smart robotic assistant should be efficient in gaining essential power with the support of solar cells and the process of photovoltaic effect. If the concurrent design solutions will be followed by the engineers for designing clean energy usage-related functionality of the robotic assistant, then they will be successful in testing the accuracy in real-time and this will eventually assist in taking corrective action in real-time without any further delay. The effectiveness of the concurrent design solution in the overall design of the proposed robotic product is presented as follows in an image format-

With the analysis of the graphical outcome of the concurrent design solution, it is found that the desired kind of robotic assistance product can be designed in an efficient style along with testing its technical and non-technical accuracy in real-time. Since the designing and production processes of the smart robotic product will be performed simultaneously due to which it will be easy for the developers and engineers to save time and cost for the project and this eventually indicates its accuracy against the overall quality metrics of "ACCESSFM". Since all the technical and non-technical designs of the proposed robotic product will be tested in real-time only in case of the concurrent designing process due to which the possibility of any human health and safety risk in the real world can be fixed during the designing phase only(accessfm, 2023). It means that in terms of health and safety metrics, the designing efficiency of the concurrent design solution is appropriate in the perspective of the industry standard "BS 7373".

On the comparative analysis of the overall effectiveness of the identified three design solutions, it is recommended to use the concurrent design option over structured design and functional designing as the earlier one will help in meeting the specifications as per industry standard in minimum time and cost. Apart from it, with the strategic usage of concurrent engineering design options, it will be easy to ensure the accuracy and safety level of each technical and non-technical trait of the robotic assistant product from an experimental perspective without having variance in terms stipulated budget and deadline.

Design Options and Decision Matrix
A decision matrix is an analytical technique with the support of which the competence of different strategies or solutions are comparatively analyzed in the context of a set of functional or quality metrics so that appropriate and cost-efficient decisions might be made to meet a determined objective(Pace, 2019). For identifying the best design solution for developing or designing the proposed smart robotic product for the management of the FMCG retailing company in order to perform inventory management work efficiently, the competence of each design option is illustrated as follows in matrix format against a set of specification-

For understanding the competence of each design option, the efficiency of every design solution is evaluated on each metric of specification on a scale of 1 to 10 where 1 indicates the least efficient and 10 depicts maximum efficiency. As per the analysis of the decision matrix, the overall efficiency of the structured design option in designing the proposed smart robotic product meeting all the technical and non-technical specifications is only 60 or 66.66 %. While the value of the function designing option is 76 or 84.44 %.On the other hand, the efficiency of the concurrent design option in meeting all the functional and non-functional specifications of the proposed robotic product during designing it is around 89 or 98.88 %. It means that the concurrent design option is the best solution out of the three options in terms of designing the smart robotic product as per the defined technical and non-technical specifications within the cost and budgeted time.

Manufacturing Process of the Design along with Highlighting its Compliance with Regulations, Risk, and Health and Safety Policies

For manufacturing the design of the proposed smart product, the principle of concurrent engineering will be followed and the stages of production are detailed as follows-

Material Procurement
This is the primary stage of manufacturing in which the required raw materials like iron, silicon, Li-Po battery, and steel relevant to the prosed smart robotic product are supposed to be procured from the cost-efficient supplier.

Different Components (Like Leg, CPU, and Hand) Development
This is the second phase of production in which every component of the robotic product is to be designed and produced simultaneously following the principle of concurrent designing and this will help in fixing any designing or functional issue at the initial level only(Fischer, et al., 2018).

Wiring Fitting and Optimization of Electric wires
This is the third stage of the manufacturing process at which necessary wiring and other electrical works like setting up the battery and connecting each element with the power source are performed as per the set specification.

Testing of All Functional Specifications
At this stage, all the developed and designed components of the robotic assistant will be tested as per the specification in a real environment and necessary modifications will be done as per necessary.

Assembling of Entire Components
Once all the components are tested in the perspective of defined specifications, they are finally moved to the assembling where a Skelton of a smart robot is manufactured using the smaller components.

Aesthetic Envelop
At this stage, the developed Skelton of the human smart robot is enveloped with a necessary insulated aesthetic so that it might not face any short circuit-related issues in a business environment.

Painting, Testing, and Out for Delivery
This is the final stage of manufacturing at which the assembled robotic product is painted and tested using the metric of set specifications and once this is approved, then it is made out for delivery to the client.

The manufacturing process is found efficient in complying with the essential regulations whether that is related to quality management or risk management as the competence of each function or trait is being tested at the same time when it is designed(Buede & Miller, 2016). Apart from it, in terms of health and safety policies, the manufacturing approach is found effective as it has tested the accuracy of each component at each level whether that is related to electric functionality or performance and this has made the proposed design option competitive.

Design Review
On the analysis of the technical and non-technical competence of the final design, concurrent engineering design, it is found that the concluded solution is efficient in developing and designing the proposed robotic product in minimum time and cost without any variation in terms of set specification. On the other hand, the limitation of the final design is that there might be a delay in presenting an outline of the proposed robotic product to the client in case of any error during the testing phase because, in this design option, both designing and production activities are performed simultaneously(Pongiglione & Calderini, 2016). For increasing the efficiency of the final design in the future, it is necessary to consider its current limitation, delay in prototype presentation to the client in case of any error during the testing phase, and this might be fixed by making a provision for blueprint development in between.

Conclusion
It is concluded that engineering design plays a significant role in the management of an organization in understanding the overall outline of a proposed product or process against the set specification and this eventually assists in taking corrective action to mitigate associated risk. It is summarized that there are three design options following which the proposed robotic assistance product can be developed against the set technical and non-technical specifications and these are structured, function-oriented, and concurrent design options. On the comparative analysis of the competence of each identified design option, it is concluded that the concurrent design solution is the most competitive option for the designing and manufacturing of the proposed robotic product in comparison to others. With the support of the concurrent design option, it will be easy to design and produce the prosed smart robotic product as per the set specification within the stipulated time and cost along with meeting the standard of BS 7373 and ACCESSFM.
