Deliverable 2: CAD Modelling and Rendered Development
The second core deliverable was the development of a detailed CAD model of the upper and lower limb ergometer using SolidWorks. The design process began with rough sketches and basic form exploration and progressed through several refinements based on feedback from the BioSpine team. The final CAD assembly captured all required components for function and adjustment, including pivoting arms, mounting geometry, and user-specific fit options for various wheelchair setups.
To communicate the design direction clearly, I also produced high-quality renders using KeyShot. These helped visualize the product in a real-world context and provided a polished reference for both internal feedback and external presentations. The CAD work enabled accurate prototyping, alignment with mechanical tolerances, and future modification, especially as the design will later integrate sensor housing and EEG inputs.
Full Render
Utilising Solidworks and then Keyshot I was able to share my design with my team, seniors and even participants.
Details
Key shots to demonstrate mechanics, logos and adjustability.
Exploded Views
In order to demonstrate the intricacy of my design a view with all the parts separated really helped communicate how it would assemble and function.
Solidworks Model
After months of development, iteration, and refinement, my final prototype has come to life. Every component has been individually modelled and tested, culminating in this fully assembled digital prototype.
