Tool Head Anti-Slip Structure for Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool heads are difficult to remove from removal tools like sockets or ratchet wrenches due to tight engagement or magnetic adsorption, often resulting in the tool head becoming stuck.
Innovation Solution
A tool head with an anti-slip structure featuring a groove segment, anti-slip structure with convex and concave portions, and a driving segment, which increases friction coefficient for easy removal by allowing fingers to grip and pull the tool head out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tight engagement or strong magnetic adsorption is used to prevent the tool head from falling off, then the stability of the tool head on the removal tool is improved, but the tool head becomes difficult to remove or stuck in the hole
Solution Approach 1:
The patent applies different surface qualities to different parts of the tool head. The outer peripheral surface has a rough surface treatment to increase friction and prevent slipping during use, while the end surface maintains a smooth finish to allow easy removal when needed. This local differentiation of surface properties resolves the contradiction between stability during operation and ease of removal.
2Ease of manufacture
If smooth surface is used on the tool head, then the ease of manufacturing is improved, but the friction coefficient is low causing the tool head to slip during removal
Solution Approach 1:
The patent applies rough surface treatment only to the outer peripheral surface where user grip is needed, while leaving other surfaces smooth for easy manufacturing. This localized application of surface treatment maintains manufacturing simplicity while providing the necessary friction coefficient for stable gripping during tool head removal.
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
The anti-slip structure enhances friction, enabling quick and easy removal of the tool head from the removal tool without excessive force, overcoming the issue of tool heads getting stuck.
Implementation Method 1
the surface of the anti-slip structure becomes coarse because of the convex portions and concave portions thereof; high roughness means high friction coefficient so that the friction between the fingers and anti-slip structure is increased

AI summary
A tool head with an anti-slip structure includes a combination segment formed on one side of the tool head, a driving segment formed on another side of the tool head, a groove segment formed the tool head and positioned between the combination segment and driving segment, and an anti-slip structure configured on the tool head and positioned between the groove segment and driving segment. With the anti-slip structure of a high friction coefficient and the groove segment, the friction can be increased so as to allow users to easily and quickly draw the tool head out of the hole of a removal tool.
