Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple IoT devices are connected to the network, then the system can provide more services and control more devices, but the process of connecting and identifying devices becomes cumbersome and complex
Solution Approach 1:
The electronic device automatically determines the external device to be controlled by itself based on phase difference and signal strength measurements from multiple antennas, without requiring manual selection or complex user interaction. The system performs self-service in device identification and connection establishment.
Solution Approach 2:
The electronic device pre-acquires signals from multiple external devices before control is needed, storing signal strength and phase difference information in advance. When control is required, the device quickly identifies the target by comparing pre-stored data with current measurements, avoiding time-consuming real-time selection.
2Measurement precision
If the user manually selects and connects to external devices one by one, then precise device identification is possible, but the control process becomes time-consuming and inconvenient
Solution Approach 1:
The patent replaces manual mechanical selection operations with automated electronic determination using signal processing. The electronic device automatically measures phase differences and signal strengths from multiple antennas to identify the external device, substituting manual selection with electronic automation.
Solution Approach 2:
The system uses changes in signal parameters (phase difference and signal strength) measured by multiple antennas to automatically determine the external device. By monitoring these parameter variations, the system quickly identifies the target device without manual intervention, reducing control time while maintaining accuracy.
3Measurement precision
If the electronic device uses multiple antennas to determine external devices based on phase difference and signal strength, then device identification becomes more accurate and intuitive, but the device complexity increases
Solution Approach 1:
The multiple antennas serve multiple functions: they simultaneously measure signal strength, determine phase differences, and enable direction finding. This multi-functionality allows the system to achieve high determination accuracy without proportionally increasing overall system complexity, as the same hardware components perform multiple measurement tasks.
