Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single clamping assembly design is used for various conductor types and sizes, then adaptability is improved, but clamping force precision deteriorates
Solution Approach 1:
The patent implements local quality by providing different clamping force characteristics for different regions or conductor types within the same assembly system. The clamping assembly can apply varying forces depending on the conductor size and type, ensuring precise clamping for each specific conductor while maintaining a standardized assembly design.
2Force
If tool operation is required for clamping, then clamping force control is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-service by designing the clamping assembly to automatically apply and control clamping force without requiring external tool operation. The assembly itself contains the mechanism to generate and regulate the clamping force, eliminating the need for separate tools while maintaining precise force control.
3Ease of operation
If separate clamping and trigger elements are used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent merges the separate clamping and trigger elements into an integrated assembly where the trigger mechanism is coupled with the clamping elements. This combination maintains the operational advantages of separate elements (easy triggering) while reducing overall device complexity through unified design and compact arrangement.
4Reliability
If high clamping forces are applied, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements dynamics by providing a trigger mechanism that allows the clamping assembly to transition between different force states. The trigger enables easy initiation of clamping action with minimal force, while the assembly then maintains high clamping force for reliable operation. This dynamic force application resolves the contradiction between easy operation and high reliability.

Implementation Method 1
a clamping spring (4), a trigger (6) and a latch (8), wherein the latch (8) engages the clamping spring (4) in a preloaded position of the clamping spring (4)... the released clamping spring (4) being configured to clamp the inserted electrical conductor (2)
Implementation Method 2
The trigger spring may be configured to be operated directly or indirectly by the electrical conductor when the electrical conductor is inserted into the wire clamping assembly... The force generated by the trigger spring and acting on the conductor should be smaller than the holding force exerted by the clamping force
