Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power transmission coil is formed in an annular shape to enable non-contact power feeding, then power transmission function is improved, but removal difficulty increases when injection needle is inserted
Solution Approach 1:
The annular power transmission coil is divided into multiple arc-shaped coil segments that can be separated from each other. This segmentation allows the coil to be opened and removed without compromising the power transmission function during use, as the segments can be reconnected after removal.
Solution Approach 2:
The power transmission coil is designed with dynamic separability, transitioning from a fixed annular structure to a separable structure. The coil segments can be dynamically separated via release mechanisms, enabling easy removal while maintaining the annular configuration during power feeding operations.
2Stability of the object's composition
If the power transmission coil maintains a fixed annular shape, then structural stability is improved, but adaptability decreases for different operational states
Solution Approach 1:
The coil structure incorporates dynamic elements that allow it to transition between a closed annular configuration during power feeding and an opened separable configuration during removal, providing adaptability for different operational states while maintaining structural integrity.
Solution Approach 2:
By segmenting the annular coil into multiple separable sections with connection mechanisms, the structure gains operational adaptability. The segments can be separated when needed for removal while maintaining the stable annular shape during power transmission, thus adapting to different operational requirements.
