FINAL OUTCOME
FINAL OUTCOME
The completed prototype successfully combined a modular shopping storage system with a lightweight transport chassis. The removable storage box transferred directly into the vehicle, while the dismantlable frame allowed the entire system to fit inside the car. Adjustable handles, stair-climbing wheels, and compartmentalised storage addressed the client's ergonomic requirements while demonstrating the successful application of user-centred engineering principles.

ENGINEERING FOUNDATIONS
ENGINEERING FOUNDATIONS
This project was developed using a user-centred engineering approach, where every design decision was based on solving a real problem experienced by the client. Rather than beginning with the appearance of the product, I first identified the practical challenges involved in transporting shopping safely and comfortably before developing engineering solutions to address them.
The project combined ergonomic design, anthropometric measurement, structural design, material selection, and mechanical assembly to create a functional prototype. Measurements of both the user and the operating environment were taken before any manufacturing began, ensuring the design was driven by evidence rather than assumptions.
PROJECT BRIEF
PROJECT BRIEF
The Problem
The Problem
The client experienced persistent back pain caused by degenerative disc disease, making routine shopping increasingly difficult. Conventional shopping bags required repeated lifting, often tipped over in the car boot, and placed unnecessary strain on the back when loading and unloading. Existing shopping trolleys solved some of these problems but introduced others, including poor organisation, awkward lifting, and limited compatibility with different vehicles.
The Objective
The Objective
Design and manufacture a modular shopping transport system capable of:
Reducing bending and lifting.
Organising shopping into separate compartments.
Sliding directly into the vehicle.
Providing adjustable ergonomics.
Remaining lightweight while maintaining structural strength.
Being practical to manufacture within the available school workshop.
DESIGN DEVELOPMENT
DESIGN DEVELOPMENT
The final trolley was developed through multiple stages of concept generation, client evaluation, and CAD development. Each iteration identified new challenges and informed the next stage of the design process, resulting in a solution that balanced practicality, manufacturability, and the client's requirements.
Initial Concepts
Initial Concepts
Figure 2.
Initial ConceptThe initial concept explored the idea of a removable storage box with adjustable dividers, inspired by wine storage systems, to help organise shopping and reduce items moving during transport. While the concept addressed the client's need to keep shopping secure, it quickly became clear that transferring a heavy insert between the trolley and the car would create an unnecessary lifting task. This first idea established the core objective of improving shopping organisation, while highlighting practical limitations that informed later designs.
Client FeedbackClient feedback identified a key usability issue: although the removable storage box improved organisation, it did not reduce the physical effort required to transfer shopping from the trolley to the car. This reinforced the importance of designing a solution that minimised lifting and improved independence, leading the project towards a more practical, user-centred design.

Figure 3.
Alternative ConceptBuilding on the initial concept, the second design introduced a removable lid secured with adjustable straps to better protect shopping during transport and outdoor use. The design considered practical issues such as weather, security, and accidental damage, while retaining the organised storage concept. However, the underlying challenge remained unchanged: the client would still need to lift the loaded container between the trolley and the car, limiting its practicality.
Client FeedbackThe client felt the enclosed design offered better protection for shopping but highlighted that it still failed to address the primary requirement of reducing physical effort. Concerns were also raised that a fixed lid could become restrictive when transporting taller items, reinforcing the need for a more adaptable solution.

Figure 4.
Alternative ConceptThis concept moved away from rigid storage boxes and explored a modular bag system inspired by reusable supermarket shopping bags. Lightweight bags reinforced with rigid rods were designed to connect together, allowing shopping to be transported as a single unit before separating into individual bags. While the concept offered greater flexibility, further evaluation identified concerns around structural strength, durability, and the stability of the connected bags when carrying uneven loads.
Client FeedbackThe client felt the modular design improved organisation but questioned whether it solved the original problem. Separating and carrying multiple connected bags still required unnecessary handling, and because the system remained fundamentally a set of shopping bags, it offered little practical advantage over existing solutions. This feedback reinforced the need to move beyond adapting current products and develop a more original engineering solution.

Figure 5.
Alternative ConceptSeeking a more innovative approach, this concept moved away from removable storage and explored a self-contained wheeled unit inspired by storage lockers. The aim was to eliminate the need for a separate trolley by allowing the storage unit itself to be wheeled directly between the supermarket and the car. While this represented a significant change in thinking, evaluation identified several practical issues, including limited manoeuvrability, insufficient wheel size for carrying heavy loads, and difficulties accessing both the vehicle and the stored shopping.
Client FeedbackThe client questioned the practicality of the design, noting that its height and narrow footprint would make it difficult to manoeuvre and unlikely to fit comfortably within the car boot. Concerns were also raised about the small castor wheels, limited steering control, low access height, and the front-opening compartment, all of which reduced confidence that the design would improve everyday usability. This feedback highlighted the importance of balancing innovation with practical, user-centred engineering.

Figure 6.
Refined ConceptFollowing the initial design review, the project shifted towards developing a trolley that better reflected the client's mobility requirements. This concept introduced adjustable-height legs to improve access to the car boot, together with a removable front panel that could be used as a loading ramp to eliminate heavy lifting. While the design represented a significant step towards a practical engineering solution, further evaluation identified concerns around structural stability, user safety, and the effort required to load the trolley into the vehicle.
Client FeedbackThe client recognised that the design had evolved in response to earlier feedback and appreciated the move towards an adjustable-height solution. However, concerns remained over the stability of the folding leg mechanism and the overall practicality of the loading system. This feedback highlighted the need for a more robust, intuitive design that inspired confidence during everyday use.

Figure 7.
Refined ConceptAfter exploring several unsuccessful approaches, the design process shifted towards mechanisms used in other industries. Inspiration came from the folding leg system of a hospital gurney, leading to a concept that allowed the trolley to roll directly into the car before the legs folded automatically beneath it. This was the first design to significantly reduce the client's need for lifting while maintaining a comfortable working height. Although the operating principle showed real potential, the length of the folding mechanism meant the trolley would need to be loaded into the vehicle lengthways, making it less practical for everyday use.
Client FeedbackThe client responded very positively to the folding leg mechanism, recognising that it addressed one of the project's primary objectives by allowing the trolley to be rolled directly into the car without lifting. The increased working height and improved accessibility made this the strongest concept so far, confirming that the project was moving in the right direction despite further refinements still being required.

Figure 8.
Refined ConceptThis concept explored telescopic legs as an alternative method of providing adjustable height while improving access to the car boot. The mechanism offered greater flexibility for the user and had the potential to simplify loading and unloading. However, further evaluation identified compromises between stability, internal storage capacity, and the space required for the telescopic mechanism. Although the underlying principle showed promise, the overall design did not provide the practical balance achieved by later concepts.
Client Feedbackhe client appreciated the adjustable-height concept but felt the design still required the trolley to be lifted into the car once the wheels had collapsed. While this would be manageable when empty, it failed to eliminate the physical effort required when carrying a full load of shopping. This feedback reinforced the project's primary objective of removing heavy lifting wherever possible.

Figure 9.
Refined ConceptThis concept explored an alternative approach to achieving an ergonomic working height by supporting the storage compartment from an elevated frame inspired by commercial clothing rails. The design successfully eliminated the need for bending when loading or unloading shopping, but introduced new engineering challenges. The suspended structure reduced confidence in its load-bearing capability, while the steering arrangement and folding mechanism made manoeuvrability and vehicle loading less practical than other concepts.
Client FeedbackAlthough the elevated design achieved the desired working height, the client felt it appeared less stable and more difficult to manoeuvre than previous concepts. Concerns were also raised about its ability to carry heavier shopping and the practicality of loading it into the car. Following this review, the hospital gurney-inspired concept was selected as the preferred design and taken forward for further development.

This early CAD concept explored a folding leg mechanism but, following further evaluation, it became clear that the design lacked the practicality required for everyday use. Developing a reliable locking mechanism proved unnecessarily complex, and the folding system introduced additional steps that reduced ease of use for the client. The concept was therefore rejected in favour of a simpler, more intuitive solution.

Figure 16.
This CAD concept explored the use of cross braces to increase the structural rigidity of the folding leg assembly. While the design appeared stronger and more visually refined, further evaluation highlighted significant manufacturing challenges. The complex brace connections could not be produced using the available manufacturing processes, and the design offered no practical solution for folding or compact storage. As a result, the concept was rejected in favour of a design that better balanced strength, manufacturability, and usability.

Figure 17.
This concept was initially intended to become the final design, but further evaluation identified a critical weakness in the rear support legs. Insufficient lateral stability reduced manoeuvrability and made the trolley less reliable during use. Although several reinforcement options were considered, each introduced further compromises in weight, complexity, or functionality. Rather than accepting these limitations, the design was abandoned in favour of a more robust engineering solution.

This CAD model represents the final design selected for manufacture. The frame was simplified to improve structural rigidity while maintaining a practical folding design. Removable joints secured with socket-head fasteners allow the trolley to be dismantled for transport and storage, with the central connections designed to accommodate quick-release pins for faster assembly and disassembly. The final design balanced strength, practicality, and manufacturability, providing the best overall solution to the client's requirements.

The final prototype was the result of a continuous design process rather than a single finished idea. Each stage built upon the previous one through research, client feedback, engineering analysis, CAD modelling, and practical manufacture. As the project progressed, several aspects of the design were refined in response to structural analysis, manufacturing limitations, and testing. One significant redesign followed the CAD development stage, where weaknesses in the original chassis highlighted the need for a more stable and manufacturable solution. Rather than treating these changes as setbacks, they became an important part of the engineering process, resulting in a stronger, more practical product that better met the original design objectives.
Figure 19. Full-scale prototype testing confirmed that the trolley could be positioned at the vehicle without requiring the client to lift the shopping compartment, validating one of the project's primary design objectives.

Balancing Ambition with Practicality
Balancing Ambition with Practicality
One of the biggest challenges was translating ambitious design ideas into a product that could realistically be manufactured using the equipment available within a school workshop. Several early concepts introduced complex mechanisms that proved impractical to build, requiring the design to be simplified without compromising its purpose.
Working Within Manufacturing Constraints
Working Within Manufacturing Constraints
The original chassis design incorporated features that exceeded the capabilities of the available tools and manufacturing processes. Alternative construction methods and modular mechanical joints were introduced to achieve similar functionality using accessible materials and equipment.

The project remained flexible throughout manufacture. Practical improvements, including the introduction of stair-climbing wheels, increased adjustability, and additional structural support, were incorporated as the prototype developed, demonstrating the importance of continual evaluation throughout an engineering project.
Figure 21. Functional TestingThe completed prototype was tested in the environments it had been designed for, including pedestrian pathways, kerbs, and vehicle loading. Practical testing confirmed that the modular storage system, adjustable handles, and stair-climbing wheels functioned as intended while highlighting the importance of validating engineering decisions through real-world use.

WHAT I LEARNED
WHAT I LEARNED
This project fundamentally changed the way I approach engineering design. I learned that successful engineering is rarely about producing the most complex solution. Instead, it requires understanding the problem thoroughly, working within realistic constraints, and continually refining ideas as new information becomes available.
I also gained a much greater appreciation for the importance of planning before manufacture. Taking accurate measurements, understanding the user's requirements, and considering manufacturing limitations at an early stage significantly reduced problems later in the project.
Perhaps most importantly, I learned that design is an iterative process. Some of my favourite ideas never reached the final prototype, but each one contributed to a better overall solution.

Good engineering isn't about creating the most ambitious idea on paper. It's about understanding the problem, designing around real constraints, and adapting your ideas until they become practical, manufacturable, and genuinely useful to the person you're designing for.
FINAL REFLECTION
FINAL REFLECTION
This was my first opportunity to experience the complete engineering design process from initial client consultation through to the manufacture of a working prototype. Looking back, the final product is very different from my earliest concepts, but I now see that as one of the project's greatest strengths rather than a weakness.
Every design change was driven by evidence, whether through client feedback, testing, measurements, or manufacturing limitations. Learning to adapt my ideas without losing sight of the original objective taught me that engineering is a process of continual improvement rather than pursuing a perfect first solution.
The project strengthened my confidence in CAD, manufacturing, problem-solving, and iterative design while reinforcing the importance of designing around the user rather than the designer. It remains one of the projects I am most proud of because it solved a genuine problem, challenged me to think like an engineer, and demonstrated how thoughtful design can have a meaningful impact on someone's everyday life.
