Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable is used to electrically connect the conductive core and the circuit board, then the connector can be mounted, but the mounting steps become complex and connection reliability problems occur
Solution Approach 1:
The patent extracts and removes the cable from the connection system. The conductive core is directly soldered to the circuit board, eliminating the cable as an intermediate component. This reduces mounting complexity while improving connection reliability by reducing potential failure points.
Solution Approach 2:
The patent merges the conductive core directly with the circuit board through soldering. The housing integrates the conductive core, allowing it to be positioned and soldered directly to the circuit board without requiring separate cable connection steps, thereby simplifying the mounting process.
2Productivity
If multiple mounting steps and components are used, then the connector can be assembled, but the mounting process becomes time-consuming and efficiency decreases
Solution Approach 1:
The conductive core is pre-integrated into the housing during manufacturing, with the solder leg extending from the housing. This preliminary integration eliminates the need for separate assembly steps during mounting, allowing the connector to be quickly positioned and soldered to the circuit board.
Solution Approach 2:
The housing and conductive core are merged into a single integrated component. The housing contains the conductive core and provides the mounting structure, eliminating the need for separate mounting steps for each component and significantly reducing mounting time.
3Reliability
If the conductive core is rigidly fixed, then the connection is stable, but mounting errors cause stress on solder legs and reduce reliability
Solution Approach 1:
The patent changes the mechanical parameter of the conductive core from rigid to flexible. The conductive core is designed with flexibility to allow slight deformations that accommodate mounting errors, preventing stress concentration on the solder legs while maintaining electrical connection stability.
Solution Approach 2:
The flexible conductive core acts as a cushioning element that absorbs mounting errors before they can transmit stress to the solder legs. This beforehand cushioning protects the solder joints from damage due to misalignment or dimensional variations during assembly.
