Pivotable Lever Clamping Mechanism for Strap Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generic clamping apparatuses increase strap wear to enhance holding forces, as they rely on roughened surfaces to increase friction, which is not necessary and leads to premature wear.
Innovation Solution
Incorporating a pivotable lever as a third clamping body that locks the strap between fixed web-like clamping bodies, generating high holding forces without the need for roughened surfaces, and utilizing curved strap abutment surfaces for increased friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If roughened surfaces are used on basic body clamping bodies to increase friction, then holding forces are improved, but strap wear increases
Solution Approach 1:
The clamping apparatus is divided into multiple basic body clamping bodies (at least two webs) that work together with a third pivotable clamping body. Each component contributes to the overall clamping force through its specific function, distributing the load and friction generation across multiple surfaces rather than relying on roughening a single surface.
Solution Approach 2:
Instead of making the strap surface rough to increase friction, the invention inverts the approach by using smooth surfaces combined with a mechanical leverage system. The pivotable third clamping body acts as a lever that amplifies the clamping force, eliminating the need for roughened surfaces and thereby preventing strap wear while maintaining high holding forces.
2Object-affected harmful factors
If smooth surfaces are used on basic body clamping bodies, then strap wear is reduced, but holding forces decrease
Solution Approach 1:
The third basic body clamping body is designed to be pivotable relative to the basic body, allowing it to dynamically adjust and apply clamping force in the optimal direction. This dynamic mechanism enables the smooth-surfaced clamping bodies to generate sufficient holding forces through mechanical leverage rather than relying on static friction from rough surfaces.
Solution Approach 2:
The invention adds a third dimension to the clamping system by introducing a pivotable clamping body that operates in a different plane or angular dimension. This additional degree of freedom allows the system to generate holding forces through rotational movement and leverage, compensating for the reduced friction from smooth surfaces.
