Pivoting Digital Display for Torque Wrench Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic torque wrenches have digital readouts or displays embedded in the handle, which are often obscured by the user's hand, making it difficult to easily view the measured torque or bending strain.
Innovation Solution
A digital display is pivotally attached to the wrench handle, allowing it to be rotated to various angular positions, with a recess and socket design enabling easy viewing of the display, and optionally featuring two screens for clear visibility of the measured data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the digital display is embedded in the wrench handle, then the structure is compact and simple, but the display is covered or shielded by the user's hand making it difficult to see
Solution Approach 1:
The digital display is made dynamically positionable through a pivot mechanism that allows it to rotate between a stored position (flush with the handle) and a viewing position (extended outward at various angles). This dynamic adjustment enables the user to optimize display visibility while maintaining a compact form when not in use.
Solution Approach 2:
The digital display is nested within a recess in the wrench handle when not in use, with the pivot mechanism allowing it to be stored flush within the handle body. This nesting approach maintains a compact overall structure while enabling extended functionality when needed.
2Adaptability or versatility
If the digital display is pivotally attached to allow rotation to various angles, then the display is easily visible from different positions, but the device complexity increases
Solution Approach 1:
The pivot mechanism provides dynamic angular adjustment capability, allowing the digital display to be positioned at various angles relative to the wrench handle. This enables adaptability to different user hand positions and viewing angles while maintaining a relatively simple mechanical implementation.
Solution Approach 2:
The pivot mechanism serves multiple functions: it enables angular adjustment for visibility, provides a stopping mechanism for positioning, and allows the display to be stored flush with the handle when not in use. This multi-functionality reduces the need for additional separate mechanisms.
3Ease of manufacture
If the digital display is embedded in the handle, then the manufacturing is simple, but the display cannot be easily stored or protected
Solution Approach 1:
The digital display is nested within a recess in the wrench handle, allowing it to be stored protected within the handle body when not in use. This provides physical protection for the display while maintaining ease of manufacturing through a straightforward recess design.
Solution Approach 2:
The pivot mechanism allows the display to be dynamically positioned between a protected stored state (flush with handle) and an exposed viewing state. This provides protection when needed while maintaining manufacturing simplicity through a basic pivot and recess design.

AI summary
An electronic torque wrench includes a wrench member mounted to a wrench handle for receiving one or more strain gages, and a digital display pivotally attached to the wrench handle for allowing the digital display to be pivoted relative to the wrench handle to different angular position and for allowing the digital display to be easily seen by the user and for allowing the bending strain or the torque or the information detected or measured by the strain gages to be easily seen from the displayer. The displayer is pivotable relative to the wrench handle to various or different angular position to allow the displayer to be easily seen by the user.
