Solution Overview

Problem

Conventional speed wrenches are limited by their fixed range of motion and angle, making it difficult to reach and manipulate objects in crowded spaces, especially when objects are connected to other devices, requiring additional space and flexibility for effective loosening or tightening.

Innovation Solution

A speed wrench with an angled offset head that allows for variable angles, providing increased flexibility and reach, combining recessive and engaging portions to facilitate efficient turning cycles without the need for reorientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional speed wrench with a fixed range of motion is used, then the wrench structure is simple, but the ability to reach and manipulate objects in crowded spaces is limited

Engineering Contradiction:

Improveability to reach and manipulate objects in crowded spacesVSAvoidwrench structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wrench head is designed with an angled offset that allows dynamic adjustment of the wrench's angle of pursuit, enabling it to adapt to various working positions and crowded spaces without requiring complex mechanical mechanisms

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The angled offset introduces a new dimensional freedom to the wrench, allowing it to operate at multiple angles simultaneously while maintaining a simple overall structure

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a speed wrench with an angled offset is designed, then flexibility and reach in confined spaces are improved, but the manufacturing complexity increases

Engineering Contradiction:

Improveflexibility and reach in confined spacesVSAvoidmanufacturing complexity

Core Design Contradiction:

AI summary

A speed wrench is disclosed having at least one recessive portion inside a speed wrench head of the speed wrench, and at least one engaging portion inside the speed wrench head. The speed wrench also has at least one angled portion providing an angled offset measured from a planar surface that the speed wrench is resting on to the center axis of the speed wrench head. The speed wrench may further be double-sided and may be an open-ended wrench.
