Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection methods (soldering or welding) are used for switch elements, then reliable electrical connection is achieved, but manufacturing complexity and process time increase
Solution Approach 1:
The patent replaces traditional mechanical connection methods (soldering, welding) with a direct plug connection system. The switch element housing contains integrated plug contacts that directly engage with corresponding receptacles on the circuit board, eliminating the need for soldering or welding processes while maintaining reliable electrical connection.
Solution Approach 2:
The switch element housing is designed with self-aligning and self-securing features. The plug contacts automatically engage with the circuit board receptacles upon insertion, and the housing structure provides automatic mechanical retention without requiring additional fastening operations or complex assembly steps.
2Ease of operation
If direct plug connection without securing elements is used, then ease of installation is improved, but mechanical stability under load deteriorates
Solution Approach 1:
The patent merges the electrical connection function and mechanical retention function into a single integrated plug contact system. The plug contacts serve dual purposes: establishing electrical connection and providing mechanical anchoring through direct engagement with the circuit board receptacles, eliminating the need for separate securing elements.
3Device complexity
If plug contacts without securing elements are used, then device simplicity is improved, but resistance to unintentional detachment deteriorates
Solution Approach 1:
The plug contacts are designed with asymmetric geometry that provides directional retention. The contact structure includes features such as angled engagement surfaces or asymmetric positioning that allow easy insertion in one direction while preventing accidental removal, creating a secure connection that resists unintentional detachment.
