Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional changer device with multiple knee levers and pivoting parts is used, then the clamping head can be changed, but the device becomes complex and costly to produce
Solution Approach 1:
The patent combines multiple knee levers and pivoting parts into a single integrated pivoting element that directly articulates on the base. This merging of components eliminates the need for separate coupling transmissions and reduces the overall number of parts, thereby simplifying the device structure and reducing production costs while maintaining the functionality of clamping head changes
2Ease of manufacture
If multiple coupling tabs and pivoting parts are used to synchronize clamping jaws, then the clamping function works, but the assembly becomes intricate and time-consuming
Solution Approach 1:
The patent extracts and eliminates the complex coupling transmission mechanism from the design. Instead of using multiple coupling tabs to synchronize pivoting elements, the invention uses a single pivoting element with integrated engagement portions that directly interact with the clamping jaws, thereby reducing the number of parts and simplifying assembly operations
3Ease of manufacture
If a simplified design with fewer parts is used, then production becomes more cost-effective, but the clamping functionality may be compromised
Solution Approach 1:
The patent segments the functionality of multiple knee levers into a single pivoting element that has multiple engagement portions distributed around its perimeter. Each engagement portion can independently interact with a clamping jaw, allowing the simplified structure to maintain full clamping functionality while reducing production costs
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in a cost-effective, easier-to-produce changer device that requires fewer parts and simplifies assembly, while maintaining effective clamping and unclamping functionality, enhancing ergonomics and reducing production complexity.
Implementation Method 1
the pivoting elements of the changer device according to the invention, by way of the engagement portions of said pivoting elements, accordingly form parts of the changer device which are deflected by an indirect manual impingement with a force so as to, on account of this, likewise deflect the clamping jaws of the clamping head

AI summary
A changer device for a clamping head having a base and pivoting elements pivotably articulated on the base and which in each case possess at least one engagement portion for impinging clamping jaws of the clamping head with a force. The changer device has a coupling transmission which per pivoting element possesses at least one coupling tab attached so as to be pivotably movable on the respective pivoting element. The changer device has a handle which for the purpose of simultaneous repositioning of the pivoting elements in relation to the base is movable in a relative manner. The handle is locationally fixed in relation to one of the coupling tabs such that a pivoting movement of the handle directly causes pivoting of the coupling tab and indirectly causes pivoting of the further coupling tab such that a pivoting movement of the pivoting elements and the engagement portions is caused.
