Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electrical components are added to detect torque and signal the operator, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines mechanical torque detection components with electrical sensing components into an integrated system. The strain gauge or torque sensor is integrated within the wrench body structure, merging mechanical force transmission with electrical signal generation to detect torque without requiring separate external detection devices.
Solution Approach 2:
The patent replaces traditional purely mechanical torque indication mechanisms (such as visual indicators or mechanical gauges) with electrical sensing components that provide more precise torque detection. The electrical components convert mechanical torque into electrical signals for accurate measurement and digital processing.
2Loss of information
If wireless communication components are added for data exchange, then information feedback capability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a wireless communication module as an intermediary between the torque wrench and external devices or systems. This module enables automatic data exchange and real-time feedback without requiring direct physical connection or manual data transfer, reducing information loss and improving communication efficiency.
3Reliability
If mechanical components generate audible click and power gap, then reliability of torque indication is improved, but ease of operation deteriorates due to requiring manual monitoring
Solution Approach 1:
The patent implements multiple feedback mechanisms including audible clicks, visual indicators, and wireless data transmission that automatically notify the operator when the torque set point is reached. This eliminates the need for continuous manual monitoring and provides reliable torque indication through automated feedback channels.
Solution Approach 2:
The patent incorporates visual indicators such as LED lights that change color or illuminate to indicate torque status. When the torque set point is approached or reached, the visual indicator provides immediate feedback to the operator, making it easier to monitor torque application without constant manual intervention.
