Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple specific devices are used for different motor gestures, then the functionality and versatility are improved, but the device complexity and cost increase
Solution Approach 1:
The patent implements a single rehabilitation device capable of performing multiple motor gestures through interchangeable grip accessories (handlebars, wheels, cranks, pedals) that can be coupled to rotary interfaces. This allows the device to support unilateral, bilateral, and coordinated exercises for both upper and lower limbs, eliminating the need for multiple specialized devices while maintaining structural simplicity
Solution Approach 2:
The device incorporates adjustable and lockable joints that enable dynamic reconfiguration of the main body orientation and rotation axis positions. This dynamic adaptability allows the same device structure to accommodate various exercise configurations and user anthropometric sizes, providing versatility without requiring multiple fixed-configuration devices
2Ease of operation
If rehabilitation devices are designed for home use, then portability and ease of use are improved, but the functionality and adaptability may be reduced
Solution Approach 1:
The device is divided into modular components including interchangeable grip accessories, adjustable joints, and separate rotary interfaces. This segmentation allows users to easily reconfigure the device for different exercises and anthropometric sizes by simply changing accessories or adjusting joint positions, maintaining high adaptability while ensuring ease of operation for home use
Solution Approach 2:
The device incorporates easy-adjustment mechanisms and lockable joints that enable users to independently reconfigure the device without requiring specialized assistance. Users can autonomously adapt the device to their specific needs and physical characteristics, combining ease of operation with full adaptability for home rehabilitation
3Device complexity
If fixed orientation devices are used, then the structural simplicity is improved, but the adaptability to different motor gestures is reduced
Solution Approach 1:
The device employs adjustable and lockable joints that enable dynamic reconfiguration of the main body orientation and rotation axis positions while maintaining a relatively simple base structure. This allows the device to adapt to different motor gestures and exercise types without requiring complex mechanical systems, achieving versatility through controlled adjustability rather than inherent structural complexity
