Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complicated clamping and adjustment mechanisms are used to ensure precise alignment and stable positioning of the tooling board, then manufacturing precision and reliability are improved, but device complexity and material costs increase
Solution Approach 1:
The mounting device is divided into separate functional modules: a clamping unit with first and second clamping jaws for securing the tooling board, and an adjustment unit with a bridge mechanism for precise positioning. This segmentation allows each module to be optimized independently while simplifying the overall assembly and reducing the number of parts compared to integrated complex mechanisms.
Solution Approach 2:
A bridge element is introduced as an intermediary component between the adjustment mechanism and the clamping jaws. The bridge serves as a mediator that transmits adjustment movements to the clamping jaws while maintaining precise geometric relationships, thereby achieving accurate alignment without requiring complex direct coupling mechanisms.
2Reliability
If complicated clamping and adjustment mechanisms are used to ensure precise alignment and stable positioning of the tooling board, then reliability is improved, but assembly time and mounting costs increase
Solution Approach 1:
The mounting device is divided into separate functional modules: a clamping unit with first and second clamping jaws for securing the tooling board, and an adjustment unit with a bridge mechanism for precise positioning. This segmentation allows each module to be optimized independently while simplifying the overall assembly and reducing the number of parts compared to integrated complex mechanisms.
Solution Approach 2:
The bridge element is pre-configured with fixed geometric relationships to the clamping jaws and adjustment mechanism. This preliminary arrangement ensures that when the adjustment unit is actuated, the clamping jaws automatically achieve the correct position and orientation, eliminating the need for time-consuming manual alignment and assembly adjustments.
3Manufacturing precision
If precise alignment mechanisms are used to maintain tooling board position, then manufacturing precision is improved, but device complexity and material input increase
Solution Approach 1:
The mounting device is divided into separate functional modules: a clamping unit with first and second clamping jaws for securing the tooling board, and an adjustment unit with a bridge mechanism for precise positioning. This segmentation allows each module to be optimized independently while simplifying the overall assembly and reducing the number of parts compared to integrated complex mechanisms.
Solution Approach 2:
The adjustment function is extracted as a separate unit with its own bridge mechanism, distinct from the clamping function. This extraction allows the alignment mechanism to be designed independently with minimal material requirements, using only the essential bridge element and adjustment actuator, while the clamping unit uses separate jaws and springs, reducing overall material input compared to monolithic complex mechanisms.

Function Achieved in This Case
The solution provides a cost-effective, quick, and precise mounting system that maintains tooling board stability during machine operation, reducing assembly time and material costs while ensuring high precision alignment.
Implementation Method 1
at least one actuator which comprises a moveable piston and a piston rod coupled to the piston, wherein the actuator is configured to transfer the at least one first clamping jaw from the locked position to the unlocked position
Implementation Method 2
at least one closing spring which is arranged so as to move the first clamping jaw towards its locked position
Implementation Method 3
the actuator is coupled to the first clamping jaw via a swivel joint. Due to the swivel joint, the actuator can buckle out in order to overcome geometric and positional tolerances
Implementation Method 4
the first and the second clamping jaws are configured to clamp a tooling board between each other... a sufficient holding force is exerted on the tooling board to inhibit an unwanted shifting of the tooling board
