Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed device structure is used between the terminal and the body, then the connector structure is simple, but the applicability to different output directions is limited
Solution Approach 1:
The terminal is designed to rotate relative to the body around a rotation axis, transforming the fixed structure into a dynamic one. The terminal can rotate from an initial position to a target position, enabling the connector to adapt to different output directions. This dynamic capability allows the connector to serve multiple applications without requiring multiple fixed structures.
2Force
If a conventional terminal structure is used, then the manufacturing is simple, but the insertion force required is relatively large
Solution Approach 1:
The terminal incorporates a resilient arm that can elastically deform during insertion. When the pin terminal is inserted, the resilient arm bends and then rebounds, using elastic energy to reduce the insertion force. This dynamic elastic deformation allows the connector to maintain simple manufacturing while significantly reducing the force required for insertion.
Solution Approach 2:
The resilient arm changes its physical state from a rigid structure to an elastic deformable structure. By changing the mechanical parameters of the terminal (introducing elasticity), the insertion force is reduced while maintaining manufacturing simplicity through the use of standard resilient materials and structures.
3Ease of operation
If the terminal is fixed in the body, then the structural stability is high, but the flexibility for different applications is reduced
Solution Approach 1:
The terminal is designed with rotational capability around a rotation axis, allowing it to dynamically adjust its orientation from an initial position to a target position. This dynamic rotation mechanism provides operational flexibility for different applications while maintaining structural stability when the terminal is positioned and locked in place.
Solution Approach 2:
The connector is divided into separable components: the body and the terminal. The terminal can be independently rotated and positioned relative to the body, then fixed in the desired orientation. This segmentation allows the terminal to be adjusted for different applications while maintaining a stable fixed connection once positioned.
