Hexagonal Hand Tool Engaging Structure for Multi-Standard Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional socket structures are limited in versatility as they can only accommodate metric specifications, failing to support British specifications or other variations, thereby restricting their applicability.
Innovation Solution
The engaging structure for a hand tool incorporates a mounting element with multiple first and second recessed portions and locking sides forming a hexagonal shape, allowing it to accommodate screw members with metric, British, and E-type specifications, ensuring compatibility and preventing wear on the screw member corners during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional socket structure with a single mounting portion is used, then the structure is simple and easy to manufacture, but it can only accommodate metric specifications, limiting versatility
Solution Approach 1:
The mounting element is designed with multiple types of recessed portions (first recessed portions with two grooves for metric specifications, second recessed portions with curved faces for British specifications, and third recessed portions for E-type specifications) within a single structure, enabling one mounting element to accommodate multiple screw member specifications and achieve multi-functionality
2Adaptability or versatility
If a mounting portion with curved recesses is used for metric specifications, then the corners of the screw member are protected from wear during rotation, but the mounting portion cannot accommodate British or E-type specifications
Solution Approach 1:
Different types of recessed portions are designed with different local geometries optimized for specific screw member types: first recessed portions with two grooves for metric specifications, second recessed portions with curved faces for British specifications, and third recessed portions for E-type specifications, allowing each local region to provide appropriate protection and engagement for its designated screw member type

AI summary
An engaging structure for a hand tool includes a main body. The main body has a mounting element. The mounting element includes multiple first recessed portions, multiple second recessed portions, and multiple locking sides. Each of the first recessed portions is provided with two grooves. Each of the second recessed portions is provided with a first curved face. Each of the locking sides has a planar shape. Each of the locking sides is arranged between two of the second recessed portions. Each of the first recessed portions is formed on one of the locking sides. The locking sides construct a first hexagon. The first hexagon has a center provided with a central axis. The first hexagon has six side faces. Each of the six side faces coincide with each of the locking sides.
