Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of cutting tools is used, then tool shape can be changed, but the process is time-consuming and prone to dimension errors
Solution Approach 1:
The cutting tool incorporates a flexible element that can dynamically change its shape in response to control signals, replacing static manual adjustment with dynamic automated control. The flexible element allows the tool to adapt its shape during operation without requiring time-consuming manual reconfiguration.
Solution Approach 2:
The patent replaces the manual mechanical adjustment system with an automated control system that uses sensors and actuators to control the flexible element's shape, eliminating human intervention and the associated time loss and dimension errors.
2Adaptability or versatility
If manual adjustment of cutting tools is used, then tool shape can be changed, but dimension errors occur
Solution Approach 1:
The system incorporates sensors that provide real-time feedback on the flexible element's shape and position, allowing the control system to make precise adjustments and maintain accurate dimensions. This closed-loop control eliminates the dimensional errors associated with manual adjustment.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated控制系统 that uses sensors and actuators to precisely control the flexible element's shape, ensuring dimensional accuracy through electronic control rather than human operation.
3Device complexity
If cutting tool deflection is not monitored, then the system is simpler, but geometric inaccuracies occur
Solution Approach 1:
The system incorporates deflection sensors that continuously monitor the cutting tool's position and shape during operation. This feedback allows the control system to detect and correct deflection in real-time, maintaining geometric accuracy without significantly increasing system complexity.
Solution Approach 2:
The system uses sensors to automatically detect and monitor deflection, and the control system automatically compensates for deflection effects, making the system self-correcting without requiring external intervention or complex manual adjustments.
