Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed rigid prosthetic mount is used, then structural stability is improved, but riding comfort and adaptability to different bike configurations deteriorate
Solution Approach 1:
The prosthetic mount incorporates a dynamic adjustment mechanism that allows the residual limb interface to rotate and translate relative to the bike frame. This dynamic system enables the mount to adapt to different bike configurations and riding positions while maintaining structural stability through controlled movement ranges and mechanical constraints.
2Productivity
If a custom-made prosthetic solution is created for each athlete, then performance optimization is improved, but device complexity and manufacturing difficulty worsen
Solution Approach 1:
The prosthetic mount is designed as a universal interface system with adjustable parameters that can accommodate multiple athletes and different bike types. The standardized base design with configurable adjustment mechanisms allows one device to serve multiple functions and users, reducing the need for completely custom solutions while maintaining performance optimization capabilities.
Solution Approach 2:
The mount is divided into modular components including an adjustable interface section, a connection section, and a mounting section. This segmentation allows independent adjustment of each module to optimize performance for different athletes without redesigning the entire system, simplifying manufacturing while maintaining customization capability.
3Ease of manufacture
If a simple fixed mount is used, then ease of manufacture is improved, but riding comfort and force application efficiency deteriorate
Solution Approach 1:
The mount incorporates rotational and translational movement capabilities that allow the residual limb interface to dynamically adjust during cycling. This dynamic functionality improves force application efficiency and riding comfort by enabling natural movement patterns while maintaining a relatively simple overall structure that remains easy to manufacture.
