Rotatable Digital Display Torque Wrench Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic torque wrenches often struggle to provide easily readable display values in confined or difficult-to-access spaces, making it challenging for users to accurately read the torque values during screw tightening operations.
Innovation Solution
A torque wrench with a rotatable digital display positioned between the shank and handle, allowing the display value to be shown in a user-friendly orientation, which can be rotated by a selectable number of degrees and automatically adjusted using sensors, ensuring readability for both right- and left-handed users, and featuring a mechanism to emit signals when the preset torque is reached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is fixed in position on the torque wrench, then the device structure is simple, but the display value cannot be read easily in different working positions
Solution Approach 1:
The display value orientation is made dynamic rather than fixed. The display automatically rotates or adjusts its orientation based on the detected working position of the torque wrench, allowing the display value to always be presented in a readable orientation regardless of how the tool is positioned during operation.
Solution Approach 2:
The mechanical solution of physically rotating the entire display assembly is replaced with an electronic/software-based solution. Sensors detect the working position and the display value orientation is adjusted through software control, eliminating complex mechanical rotation mechanisms while achieving the same functional result.
2Adaptability or versatility
If the display value is shown in a fixed orientation, then the device is simple to manufacture, but it cannot accommodate both right-handed and left-handed users in confined spaces
Solution Approach 1:
The display system is designed to serve multiple functions and adapt to multiple scenarios. By detecting the working position and automatically adjusting the display value orientation, the same display mechanism can effectively serve right-handed users, left-handed users, and various working positions in confined spaces, eliminating the need for multiple specialized display configurations.
Solution Approach 2:
The display system automatically detects the working position and adjusts the display value orientation without requiring manual intervention from the user. The torque wrench itself provides the service of orienting the display correctly based on sensor data, making the system self-adapting to different usage scenarios.

AI summary
The spanner (1) has a digital display (5) e.g. LED display, displaying an indicated value (12). The display is arranged on a shaft (2) in a region of a handle (3). The indicated value is set as a torque value (11) that represents preset torque and currently applied torque. The indicated value is rotated at an angle around 180 degrees by an input at an adjusting unit (7). An angle measuring device determines rotation of the indicated value in the display. A gyro-sensor is provided for adjusting a display position.
