Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional connection terminals are used with multiple clamping points, then electrical connection functionality is provided, but the terminal becomes bulky and clamping points interfere with each other
Solution Approach 1:
The contact frame is divided into multiple independent clamping units, each with its own spring element and contact point. These segmented units are arranged along the contact frame web, allowing each to operate independently without interfering with others, thus maintaining reliability while reducing overall terminal size
Solution Approach 2:
The contact frame is designed with a web structure that extends in multiple dimensions, allowing clamping points to be distributed along the length of the web rather than concentrated in a single plane. This dimensional arrangement prevents interference between clamping points while maintaining a compact terminal footprint
2Ease of manufacture
If traditional assembly methods are used for contact parts, then electrical connection is achieved, but assembly process is complex and time-consuming
Solution Approach 1:
The contact part is merged with the contact frame through direct integration, where the contact part forms an integral part of the contact frame structure. This eliminates separate assembly steps for securing contact parts, significantly simplifying the manufacturing process and reducing assembly time
Solution Approach 2:
The contact frame web serves multiple functions: it provides structural support, positions multiple clamping points, and integrates the contact parts. This multi-functionality reduces the number of separate components and assembly operations needed, improving ease of manufacture
3Ease of operation
If separate return springs are used for each clamping point, then independent operation is achieved, but device complexity increases
Solution Approach 1:
Multiple spring elements are merged into a single continuous spring structure that runs along the contact frame web. This unified spring provides independent clamping force at multiple points through its segmented contact legs, achieving independent operation without requiring separate return springs for each clamping point
Solution Approach 2:
The single continuous spring element performs multiple functions: it provides return force for all clamping points, maintains contact pressure at multiple locations, and allows independent deflection at each contact point. This multi-functional design achieves independent operation while reducing overall device complexity
