Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a single actuation contour is used in the actuator, then the actuator can be designed with simpler structure, but the actuator cannot achieve sufficient displacement distance of the clamping leg in a compact design
Solution Approach 1:
The actuator is segmented into multiple actuation contours (first actuation contour, second actuation contour, etc.) that sequentially engage with corresponding effective contours on the clamping spring. This segmentation allows the actuator to achieve cumulative displacement through multiple interaction stages, resolving the contradiction between compact size and sufficient displacement distance.
2Length of moving object
If multiple actuation contours are added to the actuator, then the displacement distance of the clamping leg can be increased, but the device complexity increases
Solution Approach 1:
Multiple actuation contours are merged into a single integrated actuator body, allowing sequential engagement with the clamping spring's effective contours. This merging approach achieves complex multi-stage displacement functionality without requiring separate actuators or mechanisms, thus increasing displacement capability while controlling overall device complexity.
3Volume of moving object
If the actuator is designed to be compact, then the conductor connection terminal can be used in confined spaces, but the actuation force requirements may increase
Solution Approach 1:
The actuator employs dynamic engagement of multiple actuation contours with corresponding effective contours during a sequential actuation process. This dynamic multi-stage approach distributes the actuation force requirements across different engagement phases, allowing a compact actuator design to achieve sufficient clamping leg displacement without excessive force requirements at any single moment.

AI summary
A conductor connection terminal with a spring-force clamping connection, which has a busbar and a clamping spring for connecting an electrical conductor to the busbar by the clamping spring. An actuator acts on an actuation section of the clamping spring for displacing a clamping leg of the clamping spring from a clamping position to an open position. The actuator has a first pusher section with a first actuation contour and a second pusher section with a second actuation contour. The actuator displaces the clamping leg by a first displacement distance through interaction of the first actuation contour with the first effective contour when the actuator is displaced by a first actuation distance, and displace the clamping leg of the clamping spring by a second displacement distance through interaction of the second actuation contour with the second effective contour when the actuator is displaced by a second actuation distance.
