Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If injection molding equipment is used to manufacture male and female plugs, then the plugs can be produced with integrated structure, but the production process becomes cumbersome and production cost increases
Solution Approach 1:
The male and female plugs are divided into multiple separate components (housing, terminal, sealing member, insulating piece) that can be manufactured independently using conventional processes and then assembled together. This segmentation eliminates the need for complex injection molding equipment while maintaining integrated functionality through modular assembly.
2Reliability
If conventional male and female plugs are used, then the structure is simple, but the waterproof performance is poor resulting in low safety and stability
Solution Approach 1:
The sealing member and insulating piece are nested within the housing structure, with the terminal embedded in the insulating piece. This nested arrangement creates multiple protective layers that ensure waterproof performance while organizing components efficiently within the plug assembly.
Solution Approach 2:
A sealing member (likely a rubber or elastomeric component) is incorporated into the plug structure to provide flexible waterproof sealing. This flexible element can deform to maintain sealing contact between mating plugs, ensuring reliable waterproof protection without requiring complex rigid sealing mechanisms.
3Productivity
If assembled type plugs are used, then production cost is reduced and assembly efficiency is improved, but the waterproof sealing becomes more challenging
Solution Approach 1:
The sealing member and insulating piece are pre-assembled into the housing structure before the final assembly with the terminal. This preliminary action ensures that sealing components are correctly positioned and pre-compressed, maintaining reliable waterproof sealing while enabling efficient subsequent assembly operations.
