Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If curved guide grooves are used to amplify clamping force, then clamping force transmission is improved, but mechanical stress on interacting components increases
Solution Approach 1:
The patent introduces cylindrical pins as intermediary elements between the guide grooves and clamping slides. These pins transmit forces while reducing direct contact stress between the curved guide grooves and the clamping slide bodies, thereby allowing force amplification through curved grooves without excessive mechanical stress on the interacting components.
Solution Approach 2:
The patent changes the material parameter of the cylindrical pins by using hardened steel, which has higher strength and wear resistance. This material parameter change allows the pins to withstand the high mechanical stresses generated by the curved guide grooves while maintaining reliable force transmission.
2Force
If cylindrical pins are inserted into receiving bores for high force transmission, then force transmission capability is improved, but assembly complexity increases
Solution Approach 1:
The patent designs the mounting recesses in the guide grooves to be axially aligned with the receiving bores in the clamping slides during the assembly process. This preliminary positioning arrangement allows the cylindrical pins to be easily inserted into the receiving bores through the mounting recesses without requiring complex alignment procedures, thereby reducing assembly complexity while maintaining force transmission capability.
3Ease of operation
If bearing bushes are provided on cylinder pins to reduce friction, then friction is reduced, but device complexity increases
Solution Approach 1:
The patent introduces bearing bushes as intermediary elements between the cylindrical pins and the guide grooves. These bearing bushes reduce friction by providing a low-friction contact surface, allowing the pins to move smoothly within the guide grooves. The bearing bushes are simple cylindrical components that fit onto the pins, adding minimal structural complexity while significantly reducing friction.
4Ease of manufacture
If mounting recesses are arranged axially to receiving bores for easy assembly, then ease of assembly is improved, but structural integrity may be compromised
Solution Approach 1:
The patent positions the mounting recesses in the guide grooves to be axially aligned with the receiving bores in the clamping slides during assembly. This preliminary alignment allows for easy insertion of the cylindrical pins. After assembly, the mounting recesses are not in the operational position, ensuring that the structural integrity of the guide grooves is maintained during normal operation while still providing easy assembly access.

Function Achieved in This Case
This configuration ensures reliable transmission of high forces with reduced friction and ease of assembly, while maintaining structural integrity and compatibility with liquids.
Implementation Method 1
In order to achieve the lowest possible friction between the cylinder pins and the guide grooves, bearing bushes are provided on the cylinder pins, which interact with the guide grooves of the bearing bush.
