Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication is continuously activated for monitoring, then monitoring capability is improved, but power consumption increases
Solution Approach 1:
The wireless communication unit is activated periodically based on detection results rather than continuously. The control unit determines whether to activate wireless communication by evaluating detection results from sensors, enabling periodic transmission only when necessary (e.g., when abnormalities are detected), thus reducing overall power consumption while maintaining effective monitoring capability.
2Measurement precision
If operator input is required to determine activation timing, then control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs self-determination of activation timing through the control unit evaluating sensor detection results. The acceleration sensor and other sensors automatically detect tool status and position, and the control unit autonomously decides when to activate wireless communication based on these detections, eliminating the need for operator input while maintaining precise activation timing.
Solution Approach 2:
The system uses feedback from detection results to determine activation timing. Sensors continuously monitor tool status, and the control unit uses this feedback information to automatically decide when wireless communication should be activated, achieving precise timing control without operator intervention.
3Measurement precision
If external devices are used to determine activation timing, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent merges the activation timing detection function into the existing control unit of the cutting tool. Instead of using separate external devices, the control unit integrates sensor data processing and activation timing determination, eliminating the need for additional external devices while maintaining precise timing detection capability.
Solution Approach 2:
The control unit performs multiple functions including sensor data processing, activation timing determination, and wireless communication control. This multi-functional approach eliminates the need for dedicated external devices for timing detection, reducing system complexity while maintaining measurement precision.
