Socket Resistance Structure for Secure Finger Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sockets lack sufficient friction between the grip portion and an operator's hand, leading to instability during removal and operation, especially when using fingers without a hand tool.
Innovation Solution
The socket incorporates a resistance structure with a radial or multi-ring configuration extending from the output surface to the outer periphery, providing increased friction and stability during gripping and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional socket has a smooth grip portion, then the socket structure is simple, but the friction between the grip portion and operator's hand is insufficient
Solution Approach 1:
The patent applies local quality by adding a resistance structure only to the grip portion of the socket while keeping other parts smooth. This localized modification increases friction where needed (between hand and grip portion) without complicating the entire socket structure, thereby improving gripping stability without excessive device complexity.
Solution Approach 2:
The resistance structure is segmented into multiple protrusions or patterns on the grip portion. This segmentation increases the surface area and friction points between the hand and socket, improving gripping reliability while maintaining a relatively simple overall structure through modular surface features.
2Reliability
If the socket surface is smooth, then the manufacturing process is simple, but the operator cannot grip the socket securely during removal
Solution Approach 1:
The resistance structure is applied locally to the grip portion rather than the entire socket surface. This localized approach improves secure gripping where it is most needed while minimizing the impact on manufacturing complexity, as only a specific region requires the additional structural features.
3Ease of operation
If the socket has insufficient friction surface, then the socket structure is simple, but the user cannot turn the socket stably with fingers
Solution Approach 1:
The resistance structure is concentrated on the grip portion to provide the necessary friction for stable finger operation. This localized enhancement improves ease of operation for turning and gripping without adding complexity to the entire socket structure, maintaining simplicity in non-critical areas.

AI summary
A socket includes a main body. The main body includes an output surface, an outer annular wall, and a resistance structure. The output surface is located at one end of the main body, surrounds an opening of the main body, and is perpendicular to a driving axis of the socket. The outer annular wall is connected with the output surface and includes an operating portion. The resistance structure is located on, and extends annularly along, the output surface. When an operator tries to remove the socket from a hand tool, the socket provides increased friction between the operator's hand and the output surface and therefore can be securely gripped.
