Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional communication systems are used at intersections, then installation is simple, but communication failures occur due to obstacles like large vehicles or radio wave interference
Solution Approach 1:
The patent applies the dynamics principle by making the antenna direction adjustable rather than fixed. The communication management apparatus can dynamically change the antenna's pointing direction based on real-time obstacle detection, allowing the system to adapt to changing environmental conditions and avoid communication failures caused by obstacles like large vehicles or radio wave interference.
Solution Approach 2:
The patent implements feedback by using obstacle detection results to control antenna direction changes. The system continuously monitors the communication environment, detects obstacles, and adjusts the antenna direction accordingly, creating a closed-loop control system that improves communication reliability by responding to real-time conditions.
2Reliability
If the antenna direction is fixed, then the device structure is simple, but communication failures occur when obstacles block the radio propagation path
Solution Approach 1:
The patent transforms the static antenna configuration into a dynamic one, allowing the antenna direction to be adjusted automatically based on obstacle detection. This dynamic capability enables the system to maintain reliable communication even when obstacles block the radio propagation path, while the automatic control mechanism keeps the operation simple.
Solution Approach 2:
The system performs self-adjustment by automatically detecting obstacles and changing antenna direction without requiring manual intervention. The communication management apparatus monitors its own communication environment and autonomously adjusts its configuration to maintain reliable operation, eliminating the need for complex manual operations while improving reliability.
3Reliability
If the antenna direction is changed to avoid obstacles, then communication reliability improves, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent uses feedback control where obstacle detection information directly drives antenna direction adjustment. This closed-loop mechanism improves communication reliability by continuously adapting to obstacle conditions while keeping the control logic straightforward and manageable, avoiding excessive complexity.
Solution Approach 2:
The system achieves improved reliability by changing the antenna direction parameter in response to detected obstacles. This parameter adjustment approach allows the system to adapt to varying communication conditions without requiring complex reconfiguration, maintaining simplicity while improving performance.
