Clamp Sleeve Structure for Elastic Gap Rebound and Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamp sleeves lack elasticity to enlarge the gap when the fastener is loosened, leading to poor sliding performance between the clamp sleeve and the object, and the added spring may not provide sufficient rebound.
Innovation Solution
A first connecting sheet with a thin thread is integrated into the clamp sleeve, allowing it to bulge and narrow the gap when locked, and widen when loosened, utilizing its restoring force to enhance the gap size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring is added to the gap to enable the gap to enlarge when the fastener is loosened, then the gap can rebound to a suitable size, but the device complexity increases and the spring may not provide sufficient rebound force
Solution Approach 1:
The patent removes the spring from the system entirely and replaces it with the elastic deformation capability of the connecting sheet itself. The connecting sheet's material elasticity provides the necessary gap enlargement force without requiring an additional spring component, thus reducing device complexity while maintaining reliability.
Solution Approach 2:
The patent merges the gap enlargement function into the connecting sheet structure itself. The connecting sheet serves dual purposes: maintaining the gap in the locked state and providing elastic rebound force when loosened, eliminating the need for a separate spring component.
2Ease of operation
If the clamp sleeve is always in a clamped state, then the fastener can control the gap size, but the clamp sleeve lacks elasticity to enlarge the gap when the fastener is loosened
Solution Approach 1:
The patent introduces dynamic elasticity to the connecting sheet, allowing it to deform elastically when the fastener is loosened. This enables the gap to automatically enlarge without requiring manual intervention, making the clamp sleeve adaptable to different operational states while maintaining structural stability.
3Manufacturing precision
If the first connecting sheet produces a breakage along the first thin thread when locked, then the gap becomes narrower and the first connecting sheet bulges, but the structural integrity is compromised
Solution Approach 1:
The patent incorporates a pre-designed breakage line (thin thread) in the connecting sheet that is intended to break under specific loading conditions. This preliminary weakness is strategically placed to control the breakage location and ensure precise gap size adjustment while maintaining overall structural integrity through the bulging design.
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
This solution effectively addresses the issue of gap size adjustment and sliding performance by leveraging the rebound of the connecting sheet, ensuring smooth operation and proper fixing of the clamp sleeve with the object.
Implementation Method 1
the two first extending portions are pushed away from each other due to a restoring force applied thereon by the first connecting sheet, the gap becomes wider
