Anti-slip Torque Tool Groove Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wrench and socket designs often experience slippage when applying torque to fasteners due to wear and tear, corrosion, and damage, leading to inefficiency in securing and loosening bolts and nuts.
Innovation Solution
The integration of grooves and teeth on the internal sidewalls of the torque tool provides additional biting points for the fastener head, ensuring a secure grip and reducing slippage, compatible with various types and sizes of fasteners, including hex bolts and nuts, and capable of handling both right-hand and left-hand threads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wrench and socket designs are used, then the tool structure is simple, but slippage occurs due to wear and tear, corrosion, and damage of the fastener head
Solution Approach 1:
The socket internal surface is segmented into multiple functional zones: primary engagement teeth at the opening for initial fastener engagement, secondary engagement teeth deeper inside for backup engagement, and recessed regions with enhanced surface area for additional contact. This segmentation ensures that if one engagement zone fails due to wear or damage, other zones remain functional to prevent slippage.
Solution Approach 2:
Different regions of the socket internal surface are given different geometric properties optimized for their specific functions. The engagement teeth have sharp, pointed geometries for penetrating worn fastener surfaces, while the recessed regions have enlarged surface areas for distributed contact. This local differentiation of geometric quality maximizes engagement reliability without requiring the entire socket structure to be complex.
2Reliability
If multiple engagement teeth and recessed regions are added to the socket, then slippage is reduced, but manufacturing complexity increases
Solution Approach 1:
The socket is manufactured as a single integrated piece with all engagement features (primary teeth, secondary teeth, recessed regions) formed simultaneously through stamping or molding processes. This segmentation of functional features combined with integral construction allows complex geometries to be produced in one manufacturing step, avoiding the need for multiple assembly operations and reducing overall manufacturing complexity.
Solution Approach 2:
Multiple engagement functions (primary engagement, secondary engagement, recessed contact) are merged into a single socket component rather than requiring separate elements. The engagement teeth and recessed regions are integrated directly into the socket wall structure, eliminating the need for additional parts, fasteners, or assembly steps, thereby simplifying manufacturing despite the increased geometric complexity.
3Productivity
If traditional single-point engagement is used, then the tool is easy to manufacture, but torque transfer efficiency decreases due to slippage
Solution Approach 1:
The torque transfer function is segmented across multiple engagement zones: primary teeth provide initial torque transfer, recessed regions provide distributed contact for stable engagement, and secondary teeth provide backup torque transfer. This segmentation of the torque transfer path ensures that total torque is effectively transmitted to the fastener without slippage, even if individual engagement points experience wear or damage.
Solution Approach 2:
The engagement mechanism transitions from traditional single-point or single-line contact to multi-point contact distributed across three-dimensional space within the socket. The recessed regions and multiple teeth create engagement points at different depths and locations, utilizing the third dimension to maximize contact area and torque transfer efficiency without requiring a mechanically complex multi-component system.

AI summary
An anti-slip torque tool that utilizes a plurality of grooves to prevent slippage and facilitate torque transfer to a fastener. The tool includes a wrench torque-tool body and an at least one engagement element. The wrench torque-tool body includes a plurality of internal sidewalls, a first base, and a second base. Further, each of the internal sidewalls includes a bracing surface. The engagement element includes a first pair of grooves and a second pair of grooves, wherein each further includes a primary cavity and a secondary cavity. The engagement element is laterally integrated into a specific sidewall to provide additional gripping action. The first pair of grooves and the second pair of grooves are positioned offset from each other, along the bracing surface of the specific sidewall. The primary cavity and the secondary cavity each traverse normal and into the bracing surface from the first base to the second base.
