Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional crimping pliers use a complex transmission mechanism, then crimping force can be achieved, but the structure becomes complicated and operation becomes laborious
Solution Approach 1:
The handle is divided into a fixed handle and a movable handle that can slide relative to each other along the longitudinal direction. This segmentation allows the crimping mechanism to be simplified while maintaining effective crimping force, as the movable handle provides the necessary mechanical advantage without requiring complex transmission components.
Solution Approach 2:
The crimping teeth are arranged in an annular array around the wire axis, transitioning from a linear arrangement to a radial/dimensional arrangement. This allows the crimping force to be applied uniformly in multiple directions simultaneously, achieving effective crimping with a simpler overall mechanism structure.
2Force
If conventional crimping pliers use a complex transmission mechanism, then crimping force can be achieved, but the volume of the pliers increases
Solution Approach 1:
By segmenting the handle into fixed and movable portions that slide along the longitudinal axis, the mechanism achieves force multiplication without requiring additional space for complex transmission components, thus maintaining a compact overall volume.
Solution Approach 2:
The crimping teeth are integrated directly into the movable handle structure, eliminating the need for separate transmission mechanisms. This merging of functions reduces the overall volume while maintaining effective crimping force delivery.
3Device complexity
If conventional crimping pliers lack adaptive function, then structure can be simple, but application area becomes narrow and operation becomes cumbersome
Solution Approach 1:
The crimping teeth are arranged in an annular array that can dynamically adapt to different terminal sizes. The movable handle's linear movement causes the annular crimping teeth to engage with terminals of varying diameters, providing adaptability without requiring complex adjustment mechanisms.
Solution Approach 2:
The annular arrangement of crimping teeth creates a universal crimping interface that can accommodate multiple terminal sizes and types. This single structure performs multiple functions (crimping different terminal sizes) without requiring separate tools or complex adjustment mechanisms.
4Adaptability or versatility
If conventional crimping pliers require adjustment before crimping, then adaptability can be achieved, but operation becomes cumbersome and labor-intensive
Solution Approach 1:
The annular crimping teeth automatically adapt to the terminal size being crimped without requiring manual adjustment. As the movable handle slides forward, the crimping teeth self-adjust their engagement point on the terminal, making the tool self-adaptive and eliminating cumbersome adjustment operations.
Solution Approach 2:
The dynamic sliding movement of the movable handle allows the crimping mechanism to automatically adapt to different terminal sizes during the crimping stroke itself, eliminating the need for pre-adjustment and simplifying the operation.
