Adjustable Grip Device for Hexagonal Wrenches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-angular wrench sockets can only accommodate a limited number of wrench sizes and often cause slippage during use, making it inconvenient to operate hexagonal wrenches securely.
Innovation Solution
A grip device with an adjustable mechanism comprising a tubular body, an adjustment member, and sliding components that allow for customizable clamping of hexagonal wrenches of different sizes, ensuring secure engagement without slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed number of flutes are provided in the main body, then the device structure is simple, but it can only accommodate a limited number of wrench sizes
Solution Approach 1:
The invention transforms the static flute structure into a dynamic adjustable system. The left and right slides can move along the groove to change the distance between clamping portions, allowing the device to adapt to different wrench sizes. This dynamic adjustment mechanism resolves the contradiction by enabling versatility without requiring multiple fixed structures.
Solution Approach 2:
The invention divides the clamping mechanism into separate left and right slides that can independently adjust positions. Each slide has its own clamping portion, and they can be positioned at different distances to accommodate various wrench sizes. This segmentation allows the device to handle multiple wrench specifications within a single unified structure.
2Reliability
If the wrench is engaged with the flute and inner circumference, then the wrench can be held, but it may slip off during rotating unless the user's finger contacts the lateral side
Solution Approach 1:
The adjustable slide mechanism dynamically adapts to different wrench sizes, providing reliable clamping without requiring user finger contact. The clamping force is automatically adjusted based on the wrench dimensions, ensuring stable engagement during rotation while maintaining ease of operation.
Solution Approach 2:
The device performs self-adjustment through the threaded adjustment member that automatically sets the appropriate distance between left and right slides based on the inserted wrench size. This self-service mechanism eliminates the need for manual finger contact to prevent slippage, as the device autonomously provides the necessary clamping stability.
3Adaptability or versatility
If multiple devices are prepared to use more than five wrenches, then all wrench sizes can be accommodated, but the number of devices increases
Solution Approach 1:
The invention creates a universal device that can handle multiple wrench sizes through its adjustable slide mechanism. Instead of requiring separate devices for different wrench sets, this single device can accommodate both Metric and English specifications by adjusting the distance between clamping portions, thereby reducing the total quantity of devices needed.
Solution Approach 2:
The dynamic adjustment capability allows one device to replace multiple fixed devices. By enabling the slides to move and reposition according to the inserted wrench, the device achieves multi-functionality, covering a wide range of wrench sizes without requiring users to maintain multiple separate tool sets.
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 adjustable grip device securely accommodates hexagonal wrenches of various sizes, preventing slippage and enhancing operational convenience by allowing users to clamp wrenches of both Metric and English specifications.
Implementation Method 1
The adjustment member includes threaded portion. The left slide is slidably located in the groove and includes threads which are engaged with the threaded portion of the adjustment member. When the adjustment member is rotated relative to the pin, the threaded portion of the adjustment member drives the threads of the left slide to move the left slide toward the right slide so as to clamp the hexagonal wrench.
