Multi-Size Socket Wrench with Concentric Polygonal Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional socket tools are limited in their application range as they typically only accommodate two sizes of threaded members, restricting their utility efficiency.
Innovation Solution
A wrenching tool with a polygonal fitting hole composed of two concentric equilateral polygonal holes, arranged with angular displacement, providing multiple internal angles and additional small internal angles to create multiple fitting positions for accommodating various sizes of threaded members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional socket has only two fitting positions for different sizes of threaded members, then the structure remains simple, but the application range is limited
Solution Approach 1:
The fitting hole is segmented into multiple distinct fitting positions (first, second, and third fitting positions) with different internal angle configurations. Each position can accommodate different sizes of threaded members, transforming a single-function hole into a multi-functional segmented structure that increases adaptability while maintaining overall structural simplicity
Solution Approach 2:
The socket is designed with multiple fitting positions within a single tool body, enabling one socket to perform multiple functions by accommodating different sizes of threaded members. The first fitting position with first internal angles, second fitting position with second internal angles, and third fitting position with third internal angles collectively provide universal applicability across various threaded member sizes
2Adaptability or versatility
If multiple separate sockets are used to cover different sizes of threaded members, then each socket can be optimized for its specific size, but the number of tools required increases
Solution Approach 1:
Multiple fitting positions that would traditionally require separate sockets are merged into a single integrated socket structure. The first, second, and third fitting positions coexist within one socket body, allowing users to cover multiple threaded member sizes with one tool instead of requiring multiple separate tools, thereby reducing the quantity of tools needed while maintaining comprehensive size coverage
Solution Approach 2:
The socket is designed as a universal tool with multiple fitting positions capable of accommodating different sizes of threaded members. This multi-functional design eliminates the need for multiple specialized sockets, reducing tool inventory while maintaining the ability to work with various threaded member sizes

AI summary
The present invention provides a wrenching tool having a polygonal fitting hole formed of a first equilateral polygonal hole and a second equilateral polygonal hole with the same configuration. The two polygonal holes are concentrically arranged to provide two fitting positions for fitting to threaded members. The first polygonal hole has multiple first internal angles each having two sides. A first small internal angle is further disposed on one side of each first internal angle of at least the first polygonal hole. The first small internal angles provide another fitting position for fitting to another size of threaded member. Accordingly, the wrenching tool is applicable to various sizes of threaded members.
