Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection methods (welding, riveting, gluing) are used to connect the conductive sheet to the signal transmission terminal, then the connection strength may be sufficient, but the sampling precision is poor and the process is complex
Solution Approach 1:
The invention changes the connection parameter from traditional welding/riveting/gluing to a pressing connection mechanism. The bendable portion is bent to press the conductive sheet between itself and the raised portion, creating an electrical connection without the need for complex joining processes. This parameter change improves sampling precision while maintaining connection reliability.
2Reliability
If traditional connection methods are used, then connection strength may be achieved, but the connection process is complex and time-consuming
Solution Approach 1:
The bendable portion serves a dual function: it provides structural support and simultaneously creates the electrical connection through its bending action. The pressing mechanism is self-contained within the terminal structure itself, eliminating the need for external welding equipment, riveting tools, or gluing processes. This self-service mechanism simplifies the connection process while maintaining reliable connection.
3Ease of operation
If the conductive sheet is loosely connected to the signal transmission terminal, then the connection process is simple, but the sampling precision deteriorates and safety is compromised
Solution Approach 1:
The bendable portion is designed to be dynamically bent during the connection process. By bending the flexible portion, the terminal transitions from a loose state to a pressed connection state. This dynamic action ensures firm contact between the conductive sheet and the terminal, improving sampling precision while keeping the operation simple. The pressurized contact area increases, ensuring reliable signal transmission.
