Solution Overview

Problem

In assembly processes, using multiple tools simultaneously can lead to tools being dropped due to both hands being occupied, posing a challenge in maintaining grip and mechanical advantage.

Innovation Solution

A pivotable and magnetic wrench design featuring a handle assembly with a magnetic mount that allows the shaft to pivot, enabling secure attachment to a working surface, allowing one-handed manipulation of tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a user employs both hands to hold tools simultaneously, then the user can maintain grip and mechanical advantage, but the tools may be dropped due to both hands being occupied

Engineering Contradiction:

Improvetool grip stabilityVSAvoidhand availability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The wrench is designed to attach itself to the work surface through magnetic attraction, eliminating the need for continuous manual holding. The magnetic mount automatically secures the tool in place, allowing the user to operate it hands-free or with one hand while maintaining stable positioning.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The wrench is divided into separate functional components: a magnetic mount portion that attaches to the work surface and a shaft portion that engages the fastener. This segmentation allows the magnetic mount to independently secure the tool while the shaft performs the fastening function, enabling one-handed operation.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the handle assembly is fixed to the shaft, then the structure is simple and rigid, but the shaft cannot pivot to accommodate different working angles

Engineering Contradiction:

Improveshaft pivoting capabilityVSAvoidhandle assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection between the handle assembly and shaft is made dynamic rather than fixed. The shaft can pivot or rotate relative to the magnetic mount within certain limits, allowing adaptation to different working angles and orientations while maintaining the magnetic attachment to the work surface.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The relative orientation parameter between the shaft and handle assembly is made variable. The shaft can change its angular position relative to the magnetic mount, enabling the user to adjust the working angle to match different fastener positions and access constraints.

Inventive Principle:

Principle #35Parameter changes

AI summary

A wrench includes a generally elongate shaft defining an axis and having a first end and a second end opposite the first end. The wrench also includes a handle assembly that is attached to the shaft. The handle assembly terminates in a magnetic mount that is configured to magnetically engage a working surface. The magnetic mount has a passage for receiving the shaft therethrough. The passage is sized and dimensioned to allow the shaft to pivot within the passage and with respect to the magnetic mount.
