Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If electromagnetic wave detection is used to identify appliance operations, then power consumption information becomes accessible, but system complexity increases due to spectrum analysis requirements
Solution Approach 1:
The patent introduces an electromagnetic wave detecting apparatus as an intermediary component that captures appliance operation information and transmits it to a receiving apparatus. This mediator enables power consumption monitoring without requiring direct integration with each appliance, thus reducing overall system complexity while still providing the needed information.
Solution Approach 2:
The patent replaces traditional mechanical or direct electrical connection methods for power monitoring with electromagnetic wave detection. By using RF spectrum analysis to detect emissions from appliances, the system avoids complex physical integrations while achieving the same information gathering goal.
2Measurement precision
If spectrum analysis is performed to determine appliance type and operation, then detailed power consumption data is obtained, but processing time and computational resources increase
Solution Approach 1:
The receiving apparatus performs spectrum analysis and identifies appliance types and operations in advance, storing this information for quick reference. By pre-processing and categorizing electromagnetic wave patterns, the system reduces real-time processing requirements when actual power consumption monitoring is needed.
Solution Approach 2:
The system performs comprehensive spectrum analysis only when necessary to identify new appliances or operations, rather than continuously analyzing every signal. This selective approach maintains measurement precision for power consumption while reducing overall processing time and computational burden.
