Rotating Operation Member Torque Wrench for Compact Storage

Solution Overview

Problem

Conventional torque wrenches are limited to a single function, making them unsuitable for general customers in the bicycle industry, as they lack additional features and are primarily purchased by professional mechanics.

Innovation Solution

A multifunctional torque wrench design that allows the operation member to switch between two positions, enabling torque generation and storage convenience, with an indication device displaying torque values in both positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the torque wrench is designed with a T-shaped structure for generating torque, then the torque generation function is achieved, but the storage volume increases and convenience of storage deteriorates

Engineering Contradiction:

Improvetorque generationVSAvoidstorage volume

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The operation member is designed to be rotatable relative to the main body, allowing it to switch between a first position (perpendicular to first axis) for torque generation and a second position (parallel to first axis) for compact storage. This dynamic reconfiguration enables the wrench to achieve both operational effectiveness and storage convenience.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If the operation member is fixed in position, then the structure is simple, but the versatility and additional functions are limited

Engineering Contradiction:

Improvestructural simplicityVSAvoidfunctionality

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The operation member is designed to be rotatable relative to the main body, allowing it to switch between a first position (perpendicular to first axis) for torque generation and a second position (parallel to first axis) for compact storage. This dynamic reconfiguration enables the wrench to achieve both operational effectiveness and storage convenience.

Inventive Principle:

Principle #15Dynamics

3Force

If the operation member is extended perpendicular to the main body axis, then torque generation is effective, but the overall length increases affecting portability

Engineering Contradiction:

Improvetorque generation efficiencyVSAvoidoverall length

Core Design Contradiction:

ForceVSLength of moving object

Solution Approach 1:

The operation member is designed to be rotatable relative to the main body, allowing it to switch between a first position (perpendicular to first axis) for torque generation and a second position (parallel to first axis) for compact storage. This dynamic reconfiguration enables the wrench to achieve both operational effectiveness and storage convenience.

AI summary

A multifunctional torque wrench includes a main body, an operation member, and an indication device. The main body has a driving portion, a combination portion, and a twisting portion. The driving portion pivotally drives a fastener to rotate about an axis passing through the main body. The operation member is switchable between a first position and a second position with respect to the main body. The extension portion extends along a second axis. When the operation member is at the first position, the second axis is vertical to the first axis, allowing a user to turn the main body to generate the torque for driving a fastener. The indication device is disposed between the main body and the operation member for displaying the torque value. When the operation member is at the second position, the second axis is parallel to the first axis for storage.
