Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement devices are designed for specific machine tools, then measurement accuracy is improved, but adaptability to different machine tools deteriorates
Solution Approach 1:
The measurement device is designed with a universal connection body that can be adapted to different machine tool holding devices. The connection body includes a standardized interface structure that allows the measurement device to be mounted on various machine tools without requiring device-specific modifications, thereby achieving multi-functionality and broad adaptability while maintaining measurement precision.
2Extent of automation
If measurement devices include integrated power supply and control systems, then operational autonomy is improved, but device complexity increases
Solution Approach 1:
The measurement device is segmented into modular functional units: a measurement unit with probe and sensor, a control unit with processor, and a power supply unit with battery. These segmented modules can be independently designed, tested, and maintained, reducing overall system complexity while enabling operational autonomy through wireless power management and independent control capabilities.
