Solution Overview

Problem

Utility workers face challenges in having the appropriate tools readily available while minimizing the number of separate tools to be transported and reducing the likelihood of losing tools during field work involving various shapes and sizes of fasteners.

Innovation Solution

A socket tool designed with a body extending between two ends, featuring a socket with multiple driving elements such as outer and inner cross slots, triangular slots, and a drive recess at one end to accommodate various fastener sizes and types, allowing for efficient driving of multiple sizes of fasteners with a single tool.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate tools are used to drive different sizes of fasteners, then the ability to handle various fastener types is improved, but the number of tools to be transported increases and the likelihood of losing tools increases

Engineering Contradiction:
Improveability to handle various fastener typesVSAvoidnumber of separate tools
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The socket is designed with multiple driving elements (first driving element extending through the peripheral wall, second driving element adjacent to the end face, and third driving element extending axially inward from the first driving element) that can accommodate different sizes and types of fasteners including nuts, bolts, and threaded hooks and eyes. This multi-functional design allows a single socket to replace multiple separate tools, directly resolving the contradiction between versatility and tool quantity.

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

2Adaptability or versatility

If multiple separate tools are carried for different fastener sizes, then the versatility is improved, but the weight and volume of equipment to be transported increases

Engineering Contradiction:
Improverange of fastener sizesVSAvoidtotal tool weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

Multiple driving elements are merged into a single socket structure with a unified body extending between first and second ends. The first driving element extends through the peripheral wall creating first and second wall sections, while the second driving element is positioned adjacent to the end face, and the third driving element extends axially inward from the first driving element. This consolidation of multiple tool functions into one physical object reduces the total weight and volume of equipment that utility workers must transport and manage in the field.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A socket tool is disclosed. The socket tool includes a body extending between a first end and a second end and having a centerline along a longitudinal axis of the socket tool; a socket bounded by a peripheral wall and formed at the first end, the socket including a first driving element extending through the peripheral wall, bisecting the peripheral wall into first and second wall sections; and a drive recess at the second end of the body to receive a nose of a driving tool.
