Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamps, especially those used in high-temperature applications, face issues with internal stress and deformation due to temperature changes, leading to unreliable clamping forces and reduced durability.
Innovation Solution
The clamp features inclined clamping jaws with a reinforcing line and a rotation device, along with a friction-reducing coating on the screw bolt, to minimize internal tensions and ensure reliable clamping even under temperature variations, allowing for higher and more reproducible clamping forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional clamping jaws are used without reinforcing lines, then the clamp structure is simpler, but internal stresses increase under temperature changes leading to unreliable clamping
Solution Approach 1:
The reinforcing line acts as a stress distribution element that prevents uneven deformation and internal tension buildup in the clamping jaw during thermal expansion and contraction, maintaining structural integrity and clamping reliability under temperature variations
Solution Approach 2:
The clamping jaw is formed as a composite structure with the reinforcing line integrated into the jaw body, creating a multi-component design that enhances structural stability and reduces internal stresses without significantly increasing overall complexity
2Manufacturing precision
If parallel clamping jaws are used, then the clamping mechanism is simpler, but deformation is uneven and internal tensions increase
Solution Approach 1:
The clamping jaws are arranged asymmetrically at an angle to each other rather than parallel, creating a convergent geometry that distributes deformation more evenly across the clamping surface and reduces internal tensions during the clamping process
Solution Approach 2:
The jaw arrangement transitions from a parallel (one-dimensional alignment) to an angled convergent configuration, introducing a angular dimension that improves deformation control and stress distribution across the clamping interface
3Productivity
If friction-reducing coating is applied to the screw bolt, then friction losses increase during clamping, but clamping force reproduction decreases
Solution Approach 1:
A friction-reducing coating is applied to the screw bolt surface, modifying the friction parameter to reduce friction losses during clamping operations, enabling more efficient force transmission and higher achievable clamping forces with improved reproducibility

Implementation Method 1
the screw bolt has an external thread with a friction-reducing coating. Thus, a further reduction of friction losses takes place during the clamping of the clamp
