Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual processing is used for quality testing, then ease of operation is maintained, but productivity and measurement precision deteriorate
Solution Approach 1:
The system performs self-measurement and self-control through the measuring unit that automatically monitors material removal progress and the control unit that adjusts parameters in real-time, eliminating the need for manual intervention and significantly improving productivity
Solution Approach 2:
Manual mechanical processing is replaced with an automated system combining material removal unit, measuring unit, and control unit that uses sensors and feedback loops to achieve precise control, thereby increasing both productivity and measurement precision
2Manufacturing precision
If manual processing is used for material removal, then device complexity is low, but manufacturing precision and measurement precision deteriorate
Solution Approach 1:
The measuring unit continuously monitors material removal progress and feeds this information back to the control unit, which automatically adjusts removal parameters to maintain precise control over the material removal process, achieving high manufacturing precision through closed-loop control
Solution Approach 2:
Manual mechanical processing is replaced with an automated system that uses sensors, measurement devices, and control algorithms to achieve precise material removal, trading increased device complexity for significantly improved manufacturing precision
3Measurement precision
If automated processing is implemented, then productivity and measurement precision improve, but device complexity increases
Solution Approach 1:
The measuring unit provides real-time feedback on material removal progress to the control unit, enabling precise measurement and automatic adjustment of parameters, which maintains high measurement precision while managing system complexity through intelligent control
Solution Approach 2:
The control unit serves multiple functions including coordinating material removal, processing measurement data, and adjusting parameters in real-time, thereby reducing the need for separate dedicated components and managing overall system complexity
