Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional connection devices are used with springs pressing cables against conductive parts, then electrical connection is achieved, but assembly requires complex tools and multiple operations
Solution Approach 1:
The terminal body is divided into two half-housings that are assembled together, allowing the connection device to be manufactured in simpler parts that can be easily assembled. The conductive part is separated from the insulating body, and the spring mechanism is integrated into the conductive part itself, simplifying the overall assembly process and eliminating the need for complex tools.
Solution Approach 2:
The conductive part serves dual functions: it provides electrical conduction and acts as its own retaining spring. The elastic deformation of the conductive part during assembly automatically secures it in the housing without requiring additional retaining mechanisms or complex assembly operations, making the assembly process self-service and tool-free.
2Adaptability or versatility
If connection devices are designed to accommodate large cable sections, then cable connection capability is improved, but device footprint increases
Solution Approach 1:
The spring pressure and conductive part geometry are optimized to accommodate various cable sections including larger ones, without proportionally increasing the device footprint. The elastic properties of the conductive part allow it to adapt to different cable sizes while maintaining compact dimensions through precise parameter control.
3Manufacturing precision
If multiple mounting operations are required for connection elements in sockets, then precise positioning is achieved, but assembly time increases
Solution Approach 1:
The conductive part is pre-formed with specific geometric features including deformation zones and engagement surfaces that ensure proper positioning and retention during a single assembly operation. The half-housings are pre-assembled with the conductive part integrated, so that when the terminal is installed in the base, precise positioning is achieved in one action without requiring multiple mounting operations.
