Grooved Wrench Socket Structure for Anti-Slip Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wrench sockets with smooth exterior surfaces are difficult to grip due to natural sweat or oil stains, leading to slipping and rolling, causing operational inconvenience and prolonged operation times.
Innovation Solution
The wrench socket features groove portions along its side surface, tapered along the axis with an included angle, providing anti-slip and anti-rolling capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wrench socket has a smooth exterior surface, then it is easy to manufacture, but it is difficult to grip and prone to rolling
Solution Approach 1:
The invention applies local quality by adding groove portions only to specific regions of the wrench socket body, rather than changing the entire surface. The groove portions are arranged at intervals around the side surface, creating localized friction enhancement zones that improve grip stability while maintaining the overall simplicity of the socket structure and ease of manufacture.
Solution Approach 2:
The invention segments the exterior surface by dividing it into multiple groove portions arranged at intervals, rather than creating a continuous textured surface. This segmentation approach maintains manufacturing simplicity while providing sufficient friction enhancement at key grip points, resolving the contradiction between ease of manufacture and grip stability.
2Device complexity
If the wrench socket has a smooth exterior surface, then it has simple structure, but it is prone to rolling and dropping
Solution Approach 1:
The groove portions are strategically positioned at specific locations on the side surface to prevent rolling without requiring complex structural changes throughout the entire socket. This localized approach maintains simple overall structure while providing the necessary anti-rolling functionality.
Solution Approach 2:
The groove portions are designed with curved cross-sections and tapered shapes that follow the cylindrical contour of the socket body. This curvature design allows the grooves to effectively engage with surfaces and prevent rolling, while maintaining compatibility with the socket's overall cylindrical geometry and simple structure.
3Ease of manufacture
If the wrench socket has a smooth exterior surface, then it requires no additional processing, but grip stability is poor due to sweat and oil
Solution Approach 1:
The groove portions create localized high-friction zones at specific positions on the socket surface, providing reliable grip enhancement where it is most needed during handling. This approach maintains the simplicity of the manufacturing process while significantly improving grip reliability in the presence of sweat and oil.

AI summary
A wrench socket, comprising a body having an axis, wherein the body is provided with a small-diameter section and a large-diameter section connected to the small-diameter section along the axis. The large-diameter section of the body has a side surface. A plurality of groove portions are arranged at intervals around the side surface of the large-diameter section. Each groove portion is formed on one end or both ends of the side surface along the axis. Each groove portion is tapered along the axis and has an included angle. Thereby, the wrench socket provides both anti-slip and anti-rolling capabilities, avoiding operational inconvenience and shortening operation time.
