Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If optical wireless communication connection is established between wireless devices, then communication efficiency and speed are improved, but the system becomes vulnerable to weather conditions especially rain which degrades signal quality
Solution Approach 1:
The patent implements dynamic connection destination selection by switching between multiple wireless devices based on real-time weather forecast data. The control apparatus continuously monitors weather conditions and dynamically reconfigures optical wireless communication connections to avoid adverse weather impacts, thereby maintaining both high communication speed and reliability under varying environmental conditions
Solution Approach 2:
The system changes the connection parameter (destination device) based on weather forecast data. By selecting different wireless devices as connection destinations according to predicted weather conditions, the system optimizes communication performance while avoiding weather-related degradation, thus resolving the contradiction between speed and reliability
2Reliability
If multiple wireless devices are available for connection, then communication reliability is improved through redundancy, but the complexity of managing and selecting connection destinations increases
Solution Approach 1:
The control apparatus uses weather forecast data as feedback to automatically determine optimal connection destinations. This feedback mechanism eliminates manual intervention and complex decision-making by using objective weather information to guide connection switching, thereby maintaining reliability while reducing management complexity
Solution Approach 2:
The system performs self-managed connection optimization by automatically selecting connection destinations based on weather forecast data without requiring manual configuration. The control apparatus independently monitors weather conditions and reconfigures connections as needed, reducing operational complexity while maintaining high reliability through automatic redundancy utilization
