Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torque wrench verification systems face inefficiencies in identifying and verifying multiple electronic torque wrenches without wired connections or manual operator intervention, particularly in environments where multiple wrenches are present.
Innovation Solution
A torque tester system that engages with electronic torque wrenches wirelessly, determines a reference torque value, identifies and verifies individual wrenches based on this value, and outputs verification indications, while establishing radio links for simultaneous verification of multiple wrenches using communication protocols like Wi-Fi, Bluetooth, and Zigbee.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple electronic torque wrenches are verified using wired connections, then verification accuracy is maintained, but operation complexity and time consumption increase
Solution Approach 1:
The patent replaces wired mechanical connections with wireless communication technology. The torque tester and torque wrenches communicate verification data wirelessly through radio frequency, eliminating the need for physical cable connections while maintaining data transmission accuracy. This substitution resolves the contradiction by removing the operational complexity of wired connections while preserving verification precision.
Solution Approach 2:
The patent introduces a wireless communication module as an intermediary between the torque tester and torque wrenches. This intermediary enables data transmission without direct physical contact, allowing verification to occur remotely and simultaneously across multiple devices without the complexity of manual cable management.
2Productivity
If multiple torque wrenches are verified simultaneously using wireless connections, then productivity improves, but device complexity increases
Solution Approach 1:
The torque tester incorporates a universal wireless communication interface that can simultaneously connect to and verify multiple torque wrenches of the same model. This multi-functional capability allows the single tester to handle multiple devices in parallel, improving productivity without requiring additional specialized equipment for each wrench.
Solution Approach 2:
The verification process is segmented into independent parallel channels, each handling one torque wrench simultaneously. The torque tester divides its verification capacity across multiple wireless connections, allowing simultaneous verification of multiple devices without increasing overall system complexity, as each connection operates independently.
3Ease of operation
If wireless communication is used to identify torque wrenches, then ease of operation improves, but reliability of identification decreases
Solution Approach 1:
The system uses unique identification codes (analogous to color codes) for each torque wrench. These digital identifiers are transmitted wirelessly and allow the torque tester to distinguish between multiple wrenches automatically. The unique codes ensure reliable identification while maintaining the ease of wireless operation, as each device can be recognized without manual intervention.

AI summary
A method is provided for verifying an electronic torque wrench. The method includes determining a reference torque value at a torque tester, from a torque applied by an electronic torque wrench to the torque tester with which the electronic torque wrench is engaged. The method includes receiving multiple torque values at the torque tester contemporaneous with the reference torque value determined at the torque tester, the multiple torque values received from multiple electronic torque wrenches, including the electronic torque wrench engaged with the torque tester. The method includes identifying one of the multiple torque values as a torque value from the electronic torque wrench, based on the reference torque value and the multiple torque values. The method includes performing a verification of the electronic torque wrench based on the reference torque value and the torque value as identified; and outputting an indication of the verification of the electronic torque wrench.
