Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional identification methods are used, then circuit complexity is low, but the ability to identify diverse electronic devices is limited
Solution Approach 1:
The patent replaces complex hardware circuit identification mechanisms with software-based waveform analysis. The terminal device uses a processor to send detection signals and analyze waveform characteristics (such as rising/falling edge times) to identify electronic device types, substituting physical circuit complexity with computational processing capability.
2Measurement precision
If more detection methods are added to identify various devices, then identification accuracy improves, but energy consumption increases
Solution Approach 1:
The patent employs a tiered detection strategy where the terminal device first performs basic waveform analysis to identify common electronic device types. Only when basic detection is insufficient does the system perform additional waveform characteristic analysis, thereby achieving high identification accuracy while minimizing unnecessary energy consumption from excessive detection operations.
3Adaptability or versatility
If hardware components are increased to support more device types, then device compatibility improves, but hardware cost increases
Solution Approach 1:
The patent implements a universal identification mechanism where a single detection signal waveform analysis system can identify multiple types of electronic devices (mobile phones, tablets, wearables, etc.). The processor analyzes different waveform characteristics to determine device types, allowing one hardware configuration to serve multiple identification purposes without requiring dedicated hardware for each device type.
