Electronic Torque Wrench Dual Display Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic torque wrenches with single display screens are inconvenient for users to observe torque values due to the angle difference between the user's line of sight and the display, leading to potential misreading when applying force in different directions.
Innovation Solution
The electronic torque wrench features two obliquely disposed display screens on either side of the shank, with one screen visible when applying force clockwise and the other when applying force counterclockwise, allowing users to easily read torque values from both sides without adjusting their sight angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display screen is disposed on the top face of the shank, then the user can observe the display screen at the same time when applying force, but the user can only obliquely observe the display screen due to angle difference, leading to difficulty in truly observing the display content
Solution Approach 1:
The single display screen is segmented into two separate display screens, each positioned on opposite sides of the shank. This allows each screen to be optimally oriented for viewing from different directions, resolving the contradiction between ease of observation and reading accuracy by providing direction-specific display surfaces.
Solution Approach 2:
The display screens are arranged in a spatial configuration around the shank rather than all on one face. By distributing displays across multiple dimensions and angles around the tool, the system enables accurate reading from various operational positions, simultaneously improving ease of observation and reading accuracy.
2Device complexity
If the torque value is displayed on the display screen in one fixed direction, then the display structure is simple, but when the user observes the display screen in another force application direction, the user will see the numerals in reverse direction, leading to inconvenience in use
Solution Approach 1:
Instead of using a single symmetric display face, the invention employs asymmetric positioning of multiple display screens at different angular positions around the shank. This asymmetric arrangement allows each screen to be optimized for specific viewing angles, greatly improving convenience of use while maintaining reasonable structural complexity.
Solution Approach 2:
The display system becomes multi-functional by providing multiple display screens that serve different viewing directions. Each screen functions as a dedicated display surface for specific operational positions, making the overall system universally applicable to various force application directions without requiring complex adjustable mechanisms.

AI summary
An electronic torque wrench with double display screens includes a main body having a shank. A front end of the shank has a working head. The shank is defined with a central vertical face in the longitudinal direction. The electronic torque wrench further includes a display unit having two display screens. The two display screens are respectively disposed on two sides of the central vertical face. The two display screens are disposed by an inclination and directed upward and outward, whereby a user can easily observe the torque value displayed on the display screens.
