Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a wireless charger limits the to-be-charged device to maintain stability, then charging stability is improved, but it becomes inconvenient to adjust the posture of the to-be-charged device
Solution Approach 1:
The patent applies the dynamics principle by making the second shell rotatable relative to the first shell around a rotation axis. This allows the wireless charging module to dynamically adjust its orientation to accommodate different device postures while maintaining stable charging. The rotation mechanism enables the system to transition from a static limiting structure to a dynamic adjustable one, resolving the contradiction between stability and ease of operation.
Solution Approach 2:
The patent divides the wireless charging module into two separate shells: a first shell and a second shell. The second shell, which contains the charging surface, is rotatably connected to the first shell. This segmentation allows independent movement of the charging surface relative to the base structure, enabling posture adjustment without compromising the overall stability of the charging system.
2Stability of the object's composition
If the second shell is fixed to the first shell, then structural stability is improved, but friction occurs during device rotation
Solution Approach 1:
By implementing a rotatable connection between the second shell and first shell, the patent transforms a static fixed structure into a dynamic jointed structure. This allows the second shell to rotate smoothly during device adjustment without generating sliding friction against a fixed surface, while still maintaining structural stability through the connection mechanism.
3Stability of the object's composition
If the wireless charging module is rigidly supported, then stability is improved, but wire damage risk increases due to twisting
Solution Approach 1:
The rotatable connection between the first shell and second shell creates a dynamic joint that can accommodate rotational movements. This prevents excessive twisting forces from being transmitted to the wireless charging assembly and its connecting wires, reducing the risk of wire damage while maintaining module stability during charging operations.
