Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping gap nuts often suffer from inhomogeneous stress distribution and uneven clamping effects due to rigid structures, which can lead to inefficient clamping on counter-threaded components.
Innovation Solution
A clamping gap nut design featuring a base body in the form of an open-circumference ring with flexible traction means that bridges the gap between two adjustable gap walls, allowing for a homogeneously distributed radial tension and even stress distribution, achieved through a clamping device with adjustable peripheral sections and a tensioning mechanism that can shorten or lengthen to adjust the gap width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid structures are used in clamping gap nuts, then structural strength is improved, but stress distribution becomes inhomogeneous and clamping effect becomes uneven
Solution Approach 1:
The patent applies a flexible traction means (such as a flexible membrane or thin-walled structure) that can deform elastically under load. This flexible component distributes the clamping force uniformly across the contact surface, eliminating the inhomogeneous stress distribution caused by rigid structures while maintaining sufficient structural strength through the flexibility and elasticity of the material.
Solution Approach 2:
The patent changes the physical parameters of the clamping structure by introducing flexibility and elasticity characteristics. The traction means is designed with specific material properties (elastic modulus, Poisson's ratio) that allow it to deform and distribute stress evenly, transforming the stress distribution parameter from inhomogeneous to homogeneous while maintaining the required clamping force.
2Ease of manufacture
If rigid structures are used in clamping gap nuts, then manufacturing simplicity is improved, but clamping effectiveness becomes uneven
Solution Approach 1:
The flexible traction means can be manufactured as a simple thin-walled component or membrane that conforms to the contact surface, providing even clamping effect. This approach maintains manufacturing simplicity while dramatically improving clamping reliability by ensuring uniform contact pressure across the entire clamping surface.
3Adaptability or versatility
If gap walls are made adjustable, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements adjustable gap walls that can dynamically change their position or configuration to adapt to different clamping requirements. The adjustment mechanism allows the gap width to be modified while maintaining the overall simplicity of the device structure, achieving adaptability without excessive complexity.

Function Achieved in This Case
This design ensures a more even and effective clamping action, reducing the risk of inhomogeneous stresses and improving the axial fixation of large bearings and other shaft components by providing a homogeneous radial bracing on the circumference.
Implementation Method 1
The peripherally open ring is resiliently flexible in such a way that its inner diameter can be reduced by elastically deforming the ring
Implementation Method 2
the clamping device has at least one flexible and/or bendable peripheral section of the base body that bridges the gap
