Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time data logging and external analysis capability are added to electronic torque wrenches, then the ability to determine optimal torqueing procedures is improved, but the device complexity increases
Solution Approach 1:
The patent introduces an external computer as an intermediary device that performs the complex data analysis functions. The torque wrench collects and stores torque and angle data, then transfers it to the external computer for processing. This mediator handles the computational complexity of determining optimal torqueing procedures, allowing the wrench itself to remain relatively simple while still providing advanced analytical capabilities.
Solution Approach 2:
The system is divided into separate functional modules: the torque wrench handles data collection and storage, the transceiver handles data transfer, and the external computer handles data analysis and optimization. This segmentation allows each component to be optimized independently, with the wrench focusing on precise measurement and the computer focusing on complex algorithmic analysis.
2Measurement precision
If data is logged at a high predetermined frequency, then the accuracy of torqueing parameter measurement is improved, but the data storage requirements and processing load increase
Solution Approach 1:
The system logs data at a high frequency during critical portions of the torqueing process where precise measurements are most valuable, while potentially reducing sampling during less critical phases. This partial application of high-frequency logging captures the essential information needed for optimization without continuously maximizing data collection throughout the entire process.
Solution Approach 2:
The predetermined logging frequency can be adjusted based on the specific torqueing application and criticality of the measurement. The system allows modification of the sampling rate parameter to balance measurement precision needs against storage and processing constraints for different fastening scenarios.
Data Source
AI summary
An electronic torque wrench is disclosed that instantaneously logs data in real time from a torqueing operation and can later transfer the data to an external device, such as a computer, for further analysis. For example, the computer can create a graph that can be analyzed to determine relevant parameters of the torqueing profile. The parameters of the graph can be analyzed to determine whether the torqueing operation was performed properly for a particular work piece or job task, or to assist users in future torqueing operations.
