Anchor and Release Tool for Anti-Slip Torque Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for tightening or loosening fasteners often experience slippage due to worn, corroded, or overtightened fasteners, leading to inefficiencies and safety concerns.
Innovation Solution
The anchor and release tool features a pair of engagement teeth integrated into its sidewalls, allowing for secure grip and release of fasteners, thereby preventing slippage and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wrench or socket tools are used to tighten or loosen fasteners, then the tool can apply torque to the fastener, but the tool may slip on the head portion leading to inefficiency and safety concerns
Solution Approach 1:
The engagement element is segmented into two distinct teeth: a first tooth with a first engagement surface for anchoring, and a second tooth with a second engagement surface for releasing. This segmentation allows each tooth to perform a specific function, with the first tooth providing secure grip during tightening and the second tooth enabling easy release, thereby eliminating slippage while maintaining ease of operation.
2Productivity
If excessive torque is applied to compromised fasteners, then the fastener can be removed, but the tool may slip causing damage to the fastener head
Solution Approach 1:
The first engagement surface of the first tooth is specifically designed with localized geometric features including an inclined surface and a horizontal surface. The inclined surface allows the tool to engage compromised fasteners effectively, while the horizontal surface distributes the torque load to prevent rounding of the fastener head. This local quality differentiation enables the tool to remove compromised fasteners without causing damage.
3Ease of manufacture
If the tool design uses simple engagement surfaces, then the manufacturing is easier, but the tool cannot effectively engage compromised or corroded fasteners
Solution Approach 1:
The first tooth and second tooth are designed with asymmetric engagement surfaces. The first engagement surface includes an inclined surface followed by a horizontal surface, while the second engagement surface has a different geometric configuration. This asymmetric design allows the tool to effectively engage compromised, corroded, or overtightened fasteners while remaining manufacturable using standard machining processes.

AI summary
An anti-slip torque tool that utilizes a pair of teeth designed to virtually eliminate slippage and facilitate torque transfer to a fastener. The tool includes a wrench torque-tool body and at least one engagement element. The wrench torque-tool body includes a plurality of internal sidewalls, an engagement first base, and an engagement second base. The engagement element is laterally integrated into a specific sidewall to provide additional gripping action. To perform this function, each engagement element further includes a first tooth and a second tooth. Both the first tooth and the second tooth are positioned offset from each other, along a sidewall base surface. The first tooth is the anchoring tooth, designed to grip the fastener specifically from off the corner off a male hex fastener. In contrast, the second tooth is the releasing tooth, designed to release the tool from the fastener.
