Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lead wire is bent and inserted into the wiring hole for connection, then the terminal can be assembled, but it cannot meet the requirements of special working conditions
Solution Approach 1:
Instead of bending the lead wire to fit into a hole, the invention inverts the approach by having the lead wire pass through a guide hole straight and be clamped by a clamping plate. This reversal of the traditional insertion method eliminates the need for wire bending while achieving secure connection, directly resolving the contradiction between adaptability to special conditions and ease of operation.
2Reliability
If a multilink mechanism is used to lock the lead wire, then the lead wire can be secured, but the terminal volume increases
Solution Approach 1:
The invention extracts the complex multilink mechanism and replaces it with a simplified structure consisting of a clamping plate, guide hole, and positioning block. This extraction removes unnecessary mechanical complexity while retaining the essential function of securing the lead wire, thereby reducing terminal volume while maintaining locking reliability.
Solution Approach 2:
The invention employs a simple clamping plate structure that can be easily manufactured and replaced if needed, rather than using a complex, expensive multilink mechanism. This approach prioritizes simplicity and cost-effectiveness over mechanical sophistication, reducing both volume and manufacturing complexity while achieving the required reliability.
3Reliability
If a multilink mechanism is used for lead wire locking, then the wire can be secured, but the structure becomes complex and costs increase
Solution Approach 1:
The invention extracts the complex multilink mechanism and replaces it with a simple clamping plate, guide hole, and positioning block assembly. This extraction eliminates unnecessary mechanical complexity while preserving the essential function of secure lead wire connection, directly resolving the contradiction between connection reliability and structural simplicity.
4Ease of manufacture
If the terminal is designed with a fixed structure, then manufacturing is simple, but it is difficult to disassemble
Solution Approach 1:
The invention segments the terminal into distinct functional components: a base body with guide hole, a removable clamping plate, and a positioning block. This segmentation allows the terminal to be manufactured using simple processes while enabling easy disassembly by removing the clamping plate, thus resolving the contradiction between manufacturing simplicity and disassembly ease.
