Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a press-fit connection is used between signal connector and circuit board, then electrical connection is established, but precise positioning is difficult due to dimensional tolerances
Solution Approach 1:
The patent introduces an intermediary positioning structure consisting of positioning protrusions on the circuit board that engage with corresponding positioning recesses on the signal connector. This intermediary mechanism mediates between the press-fit connection and the dimensional tolerances, ensuring precise positioning while maintaining reliable electrical connection.
Solution Approach 2:
The positioning protrusions and recesses are pre-configured on the circuit board and signal connector respectively, establishing the correct relative position before the press-fit connection is made. This preliminary positioning action prevents misalignment during assembly and ensures accurate electrical connection.
2Ease of operation
If dimensional tolerances are considered in the design, then assembly is more flexible, but manufacturing cost increases
Solution Approach 1:
The positioning protrusions and recesses are designed to automatically self-align the signal connector with the circuit board during assembly. This self-service mechanism eliminates the need for complex external positioning fixtures or precision alignment procedures, reducing manufacturing costs while maintaining assembly flexibility.
Solution Approach 2:
The connection system is segmented into distinct functional elements: positioning protrusions for alignment, press-fit contacts for electrical connection, and insulating bodies for structural support. This segmentation allows each element to be optimized independently for its specific function, simplifying manufacturing while ensuring overall assembly flexibility.
