Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the seat is integrated with the chassis, then the structural stability is improved, but the adaptability and ease of repair deteriorate
Solution Approach 1:
The seat assembly is divided into separable components including the seat pan, backrest, armrests, and footrests that can be independently removed from the chassis. This segmentation allows the seat to maintain structural integrity when assembled while enabling easy customization and adaptation by swapping individual components or the entire seat assembly.
Solution Approach 2:
The seat assembly is designed as a removable unit that can be completely detached from the wheelchair chassis through quick-release mechanisms. This extraction capability allows users to replace the entire seat assembly for repairs, upgrades, or customization without affecting the chassis structure, thereby maintaining stability while improving adaptability.
2Stability of the object's composition
If the seat is integrated with the chassis, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The seat assembly components are designed to be easily separated from each other and from the chassis. Individual parts such as armrests, footrests, and cushions can be removed independently for repair or replacement, while the main seat assembly can be quickly detached from the chassis using quick-release mechanisms, making repairs accessible without disassembling the entire wheelchair structure.
3Device complexity
If the seat is integrated with the chassis, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The seat assembly is designed as a universal component that can be attached to and removed from the wheelchair chassis. This multi-functional design allows the same seat assembly to be used across different wheelchair configurations or models, enabling users to adapt their mobility device to different needs by swapping seat assemblies without requiring complex customization of the entire system.
4Device complexity
If the backrest is fixed, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The backrest is designed with adjustable features including height adjustment mechanisms and angle adjustment capabilities. These dynamic features allow the backrest to adapt to different user preferences and needs while maintaining a relatively simple overall structure through the use of standardized adjustment mechanisms that can be integrated into the seat assembly without significantly increasing complexity.
