Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resistance measurement is used to determine acupuncture meridian status, then measurement is possible, but measurement precision deteriorates due to skin resistance variations caused by age, injuries, weather changes, and sweat production
Solution Approach 1:
The patent changes the measurement parameter from resistance to capacitance. By measuring capacitance values at acupuncture points and comparing them to reference values, the system determines meridian status without being affected by skin resistance variations caused by age, injuries, weather, or sweat. This parameter substitution resolves the contradiction by providing reliable measurements independent of skin condition variables.
2Measurement precision
If saline is applied to the measurement point to prevent resistance measurement errors, then measurement precision improves, but device reliability deteriorates due to corrosion and shortened service life of measuring connectors
Solution Approach 1:
The patent eliminates the need for saline application by changing from resistance measurement to capacitance measurement. Capacitance measurements do not require conductive media like saline, thereby preventing corrosion of measuring connectors and extending device service life while maintaining measurement precision through capacitance-based detection.
3Adaptability or versatility
If complex apparatus with resistance meter and capacitance meter combined with changeover switch is used, then measurement capability is comprehensive, but device complexity increases
Solution Approach 1:
The patent extracts and eliminates unnecessary components from the measurement system. Instead of combining resistance meter and capacitance meter with changeover switches, the invention uses a simplified capacitance measurement circuit that directly measures capacitance values. This extraction of redundant components reduces device complexity while maintaining comprehensive measurement capability through capacitance-based assessment of acupuncture points.
