Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional actuator components with standard ramping surfaces are used, then the assembly provides sufficient clamping force, but the assembly lacks compactness and has larger dimensions
Solution Approach 1:
The patent changes the geometric parameters of the actuator surfaces by introducing different acute internal angles (α for relief surface, β for ramping surface) relative to the actuator axis. This angular parameter optimization enables compact dimensions while maintaining reliable clamping functionality through improved force distribution.
2Reliability
If the actuator component is designed with larger dimensions for stability, then component stability improves, but the likelihood of elements falling during assembly increases for small tools
Solution Approach 1:
By optimizing the acute internal angles α and β of the actuator surfaces, the patent achieves stable assembly with compact dimensions, eliminating the element falling risk associated with oversized components in small tool applications.
3Device complexity
If conventional actuator designs are used, then the assembly provides adequate clamping function, but the construction is not compact and requires more components
Solution Approach 1:
The patent merges the relief surface and ramping surface into a single integrated actuator component with optimized angular geometry, reducing the total number of components while achieving compact dimensions and maintaining clamping functionality.

AI summary
A machine tool assembly includes a basic body, and a clamp and an actuator component mounted to the basic body. The clamp and actuator components include ramping surfaces for cooperatively biasing the clamp into an engagement position. The actuator component is configured to move along an actuator movement axis and includes an actuator relief surface connected, and extending at a different angle, to the actuator component's ramping surface. The different angle is configured to facilitate disengagement of the actuator component and clamp for a smaller movement of the actuator component along the actuator movement axis than would have been the case in the absence of such configuration, thereby allowing a compact construction of the assembly.
