Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If monitoring period is extended to improve sorting accuracy, then detection precision improves, but power consumption and cost increase
Solution Approach 1:
The sensor operates in periodic cycles, alternating between monitoring mode (collecting battery data) and communicating mode (transmitting data wirelessly). This periodic operation allows extended monitoring periods while reducing average power consumption, as the high-power communicating circuit is not continuously active.
Solution Approach 2:
The system dynamically switches between different operational modes (monitoring mode and communicating mode) based on operational requirements. The control circuit adjusts the operating state of monitoring and communicating circuits in real-time, enabling the system to adapt power consumption to actual needs while maintaining extended monitoring capability.
2Measurement precision
If monitoring period is extended to improve sorting accuracy, then detection precision improves, but cost increases
Solution Approach 1:
The patent replaces wired communication infrastructure with wireless communication technology. This eliminates the need for complex physical connection systems, reducing installation and maintenance costs while enabling extended monitoring periods that improve sorting accuracy.
3Productivity
If all circuits remain active continuously, then data collection is continuous, but power consumption increases
Solution Approach 1:
The system implements periodic operation where the monitoring circuit collects data during monitoring mode, then the communicating circuit transmits accumulated data during communicating mode. This periodic alternation maintains data collection productivity while significantly reducing power consumption by keeping circuits inactive during their non-operational phases.
Solution Approach 2:
The monitoring circuit continuously collects battery data during monitoring mode, ensuring uninterrupted data acquisition. The system maintains continuous useful action in data collection while managing power consumption through periodic transmission cycles, rather than requiring all circuits to remain continuously active.
