Solution Overview

Problem

Traditional torque tools often experience slippage when engaging with fasteners due to wear, corrosion, or damage, leading to inefficient torque transfer and potential stripping of fasteners.

Innovation Solution

An anti-slip torque tool with integrated engagement features such as grooves, serrations, ribs, edges, and surfaces that provide additional biting points on the fastener head, allowing for improved torque application regardless of wear or damage, and is compatible with various types and sizes of fasteners including hex bolts and nuts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional torque tools are used to engage with fasteners, then the tool can apply torque to the fastener, but slippage occurs due to wear, corrosion, or damage to the fastener head

Engineering Contradiction:
Improvetorque transfer reliabilityVSAvoidslippage and fastener damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The torque tool incorporates engagement features with varying local geometries (teeth, ribs, edges, grooves) that create different contact points and pressure distributions on the fastener head. This local quality variation allows the tool to maintain reliable torque transfer even when portions of the fastener head are worn or damaged, as the engagement features can adapt to the actual contact surfaces.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The engagement features are divided into multiple segmented portions including teeth, ribs, edges, and grooves that can independently engage with different portions of the fastener head. This segmentation allows the tool to distribute torque across multiple contact points, preventing slippage at any single point and reducing the risk of fastener damage.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple engagement features are integrated into the torque tool, then slippage is prevented and torque transfer is improved, but the device complexity increases

Engineering Contradiction:
Improvetorque transfer efficiencyVSAvoidtool structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple engagement features (teeth, ribs, edges, grooves) are merged into a single integrated torque tool body, allowing all features to work simultaneously on the same fastener. This combining approach provides reliable torque transfer through multiple contact points without requiring separate tools or attachments, thus managing complexity while improving reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The torque tool is designed with multi-functional engagement features that can adapt to various fastener head conditions (worn, damaged, corroded). The same set of engagement features can engage with different portions of the fastener head depending on the condition, providing universal applicability across different fastener types and conditions without requiring multiple specialized tools.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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 tool effectively prevents slippage and damage to fasteners by enhancing torque transfer, eliminating the need for bolt extractors and ensuring efficient operation with both male and female fasteners, reducing the risk of overtightening and corrosion-related issues.

Implementation Method 1

The present invention uses a series of segmented portions that engage and/or bite into the head of the fastener and allow for efficient torque transfer between the torque tool and the head portion of the fastener

Methodology Applied
Scientific EffectFriction: Friction

Implementation Method 2

The head receives an external torque force and is the means by which the fastener is turned, or driven, into the female threading

Methodology Applied
Scientific EffectTorque: Torque

AI summary

An anti-slip torque tool with integrated engagement features includes a torque-tool body and a plurality of engagement features. The plurality of engagement features is radially distributed around a rotational axis of the torque-tool body. Each of the plurality of engagement features includes a first cavity surface, a first bracing surface, a second bracing surface, and a second cavity surface. The first bracing surface and the second bracing surface are adjacently connected to each other through an intersection point. The first cavity surface is terminally connected to the first bracing surface through a first connection point as the first bracing surface is positioned in between the second bracing surface and the first cavity surface. The second cavity surface is terminally connected to the second bracing surface through a second connection point as the second bracing surface is positioned in between the first bracing surface and the second cavity surface.
