Sleeve Structure with Elastic and Resisting Components for Tool Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sleeve structures often fail to securely grip working tools, leading to tools falling off due to excessive user force, which wastes time and increases manufacturing costs with additional accessories.
Innovation Solution
A sleeve structure incorporating a sleeve body with a tooth structure, a stopping structure, an elastic component, and a resisting component, where the elastic component grips the tool and the resisting component prevents it from falling out, enhancing the gripping effect and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sleeve structure uses a simple gripping design, then the manufacturing cost is low, but the gripping effect and stability are insufficient causing tools to fall off
Solution Approach 1:
The tooth structure is divided into multiple teeth arranged circumferentially, with each tooth capable of independently engaging with the tool surface. This segmentation allows the gripping function to be distributed across multiple contact points, enhancing overall gripping stability without requiring a completely complex sleeve design
Solution Approach 2:
The elastic component is positioned specifically at the根部 of the teeth to provide localized elastic deformation capability. This allows the gripping force to be concentrated where it is most needed (at the tooth-root area), improving gripping reliability without adding complexity throughout the entire sleeve structure
2Reliability
If the sleeve structure uses additional accessories to increase stability, then the gripping effect is improved, but the manufacturing cost increases
Solution Approach 1:
The elastic component and resisting component are integrated directly into the sleeve body structure, forming a unified component rather than separate accessories. The tooth structure, stopping structure, and elastic component work together as an integrated system, reducing the need for additional separate parts and lowering manufacturing costs while maintaining improved gripping stability
Solution Approach 2:
The tooth structure serves multiple functions: it provides the gripping surface, transmits the gripping force through the elastic component, and works with the stopping structure to prevent tool drop-off. This multi-functionality eliminates the need for separate gripping accessories, reducing manufacturing complexity and cost
3Force
If the elastic component protrudes significantly from the groove, then the gripping force is stronger, but the tool cannot be easily removed
Solution Approach 1:
The elastic component is designed to dynamically adjust its protrusion state based on the applied force. During tool insertion and gripping, the elastic component deforms to provide strong gripping force. During tool removal, the elastic component returns to its original position, reducing resistance and enabling easy tool extraction

Function Achieved in This Case
The sleeve structure effectively improves the gripping effect and stability of the tool, allowing for easier tool removal and reduced manufacturing costs by integrating the components within the sleeve design.
Implementation Method 1
The elastic component is disposed in the first groove and slightly protruded from the first groove

AI summary
A sleeve structure includes a sleeve body, a tooth structure, a stopping structure, an elastic component and a resisting component. The sleeve body includes an opening hole. The tooth structure is disposed around an inner wall of the sleeve body, and includes a first groove and a second groove. The first groove and the second groove are disposed around the tooth structure, and the first groove is closer to the opening hole than the second groove. The stopping structure is disposed around the inner wall of the sleeve body, and the stopping structure is farther from the opening hole than the tooth structure. The stopping structure includes a through hole and an inner surrounding wall. The elastic component is disposed in the first groove and slightly protruded from the first groove. The resisting component is disposed in the second groove.
