Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high frequency bands (millimeter wave, terahertz) are used for wide-band transmission, then transmission bandwidth is improved, but coverage area is reduced due to high rectilinearity of radio waves
Solution Approach 1:
The patent introduces a repeater device as an intermediary component between the base station and wireless terminals. This repeater receives radio waves from the base station, amplifies them, and retransmits them to extend coverage. The repeater acts as a mediator that overcomes the limited coverage of high-frequency radio waves while preserving the bandwidth benefits of millimeter wave and terahertz band transmission.
2Area of stationary object
If a repeater device is introduced to extend coverage, then coverage area is improved, but system complexity increases due to lack of defined control mechanisms
Solution Approach 1:
The patent makes the existing wireless terminal multi-functional by enabling it to perform repeater control functions. The wireless terminal that already handles communication can additionally control the repeater device, eliminating the need for separate dedicated control infrastructure and reducing overall system complexity while maintaining coverage extension capabilities.
Solution Approach 2:
The system enables self-service by allowing the wireless terminal to autonomously control the repeater device using standard communication protocols. The terminal can independently manage repeater operations without requiring external network intervention, simplifying the control mechanism and reducing system complexity.
3Device complexity
If wireless terminal controls repeater device, then control mechanism is simplified, but reliability may be reduced compared to base station controlled repeaters
Solution Approach 1:
The patent implements feedback mechanisms where the wireless terminal reports repeater control status and performance metrics to the base station. This feedback loop allows the base station to monitor and verify repeater operations, ensuring reliability while maintaining the simplified control architecture. The feedback enables remote verification and potential intervention if issues arise.
