Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional maintenance detection methods are used, then the system is simple and easy to operate, but the detection accuracy and reliability are insufficient
Solution Approach 1:
The patent replaces traditional mechanical inspection methods with electromagnetic field-based detection. EM sensors detect electromagnetic emissions from electrical components, enabling non-contact, automated monitoring of component health status, thereby improving detection accuracy without requiring complex physical disassembly or contact-based measurement systems
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium to detect the health status of electrical components. By measuring EM emissions and comparing them against reference values, the system indirectly assesses component condition without direct contact or complex mechanical intervention, resolving the contradiction between simple operation and accurate detection
2Reliability
If EM emission detection is implemented, then maintenance problem detection accuracy improves, but the device complexity increases
Solution Approach 1:
The system utilizes the electromagnetic emissions that electrical components naturally generate during operation as the detection signal source. No additional excitation devices or complex testing equipment are needed - the components' own operational emissions serve as the diagnostic information carrier, improving reliability while avoiding the complexity of active testing systems
Solution Approach 2:
The patent creates a virtual model of normal EM emission patterns by collecting and storing reference data from healthy components. This reference model serves as a template for comparison, enabling reliable detection of deviations without requiring complex diagnostic algorithms or extensive expert knowledge, thus improving reliability while keeping the system manageable
3Loss of time
If real-time EM emission monitoring is performed, then early detection capability is improved, but energy consumption increases
Solution Approach 1:
The system performs EM emission measurements at periodic intervals rather than continuously, collecting data at strategically chosen moments during vehicle operation. This periodic sampling approach enables early detection of maintenance issues while significantly reducing the energy consumption compared to continuous monitoring, as the sensors and processing are activated only at measurement intervals
