Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile terminal uses a battery for power supply, then the terminal can operate portably, but the battery voltage will be depleted causing communication disruptions
Solution Approach 1:
The patent combines the power supply function with the antenna system by integrating a power supply unit into the antenna apparatus. This merging allows the antenna system to simultaneously perform its traditional function of receiving/radiating radio waves and the additional function of providing power to mobile terminals, thereby eliminating the battery depletion problem while maintaining portable operation.
Solution Approach 2:
The antenna apparatus is designed to serve multiple functions: it acts as both a communication antenna for receiving and radiating radio waves and a power supply device for charging mobile terminals. This multi-functionality resolves the contradiction by enabling the system to provide both portable operation and continuous power supply without requiring separate devices.
2Reliability
If power is provided to mobile terminals through the antenna system, then continuous operation is enabled, but high-frequency signals may interfere with direct current voltage supply
Solution Approach 1:
The patent segments the power supply and signal transmission functions into separate pathways within the antenna system. The power supply unit provides direct current voltage through dedicated power supply lines, while the antenna elements handle high-frequency radio wave signals. This segmentation prevents interference between the two functions while enabling continuous power supply.
Solution Approach 2:
The patent introduces an intermediary mechanism (the power supply unit with separate power supply lines) that mediates between the antenna system and the mobile terminal. This intermediary enables power transfer without allowing high-frequency signals to contaminate the direct current voltage supply, thus resolving the interference problem while maintaining continuous power availability.
