Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless signal identification is performed through traditional methods, then the electronic device can identify the wireless signal type, but the identification process is tedious and slow
Solution Approach 1:
The patent applies preliminary action by pre-establishing the correspondence between power supply loops and antenna types. When an external antenna is docked, the system immediately detects which power supply loop is activated and directly determines the antenna type based on this pre-established mapping relationship, eliminating the need for time-consuming traditional identification processes.
2Reliability
If multiple external antennas are configured in the electronic device, then the device can receive wireless signals with better signal strength and quality, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the antenna system into multiple independent external antennas, each associated with a specific power supply loop. This segmentation allows the system to handle different antenna types (satellite navigation, radio frequency, wireless local area network) independently through dedicated detection and switching mechanisms, making the complex multi-antenna system manageable and controllable.
Solution Approach 2:
The patent introduces power supply loops as intermediaries between the external antennas and the control system. Each power supply loop serves as a mediator that not only provides power to a specific antenna type but also acts as an identification signal, allowing the system to determine which antenna is docked by detecting which power supply loop is activated, thereby simplifying the overall control architecture.
3Adaptability or versatility
If traditional antenna switching methods are used, then the electronic device can switch between antennas, but the switching speed is slow and cannot quickly adapt to different wireless signal types
Solution Approach 1:
The system performs preliminary configuration by establishing fixed mappings between power supply loops and antenna types before operation. When switching is needed, the system immediately detects the activated power supply loop and directly switches to the corresponding pre-configured antenna, achieving rapid adaptation without complex real-time decision-making processes.
