Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 5G communication technology is used to achieve high data throughput, then data transmission rate is improved, but heat generation increases causing overheating
Solution Approach 1:
The patent implements periodic switching between first and second RF circuits based on accumulation of processing time. When the first RF circuit has processed signals for a designated period or more, the system switches to the second RF circuit, creating a periodic action pattern that prevents continuous heat generation from a single circuit while maintaining high data throughput capability
Solution Approach 2:
The patent divides the RF circuit system into multiple independent RF circuits (first RF circuit and second RF circuit) that can be switched between. This segmentation allows the system to distribute the heat generation load across multiple circuits over time, preventing any single circuit from overheating while maintaining overall system productivity
2Duration of action of stationary object
If RF circuit processing time accumulates for a designated period, then continuous operation is maintained, but overheating and component damage risk increases
Solution Approach 1:
The patent implements a feedback mechanism that monitors the accumulation of processing time for each RF circuit. When the accumulated processing time reaches a designated threshold, the system automatically triggers a switch to the other RF circuit. This feedback-based control ensures continuous operation is maintained while preventing overheating damage by responding to the actual operational state of the circuits
3Device complexity
If single RF circuit is used continuously, then device complexity is reduced, but heat generation causes performance deterioration
Solution Approach 1:
The patent introduces dynamic switching capability between first and second RF circuits based on real-time monitoring of processing time accumulation. This dynamic operation allows the system to adapt its configuration during runtime, switching between circuits to manage heat generation while maintaining acceptable complexity levels through automated control logic
