Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lighting control data is transmitted to multiple illumination devices using conventional methods, then control quality is maintained, but bandwidth demand becomes excessively high for wireless networks
Solution Approach 1:
The patent merges control data for multiple illumination devices into a single aggregated data structure that identifies common control parameters applicable to multiple devices. This consolidation reduces redundant data transmission while maintaining the ability to control individual devices, thereby reducing overall bandwidth demand without sacrificing control quality.
Solution Approach 2:
The invention creates a universal control data format that can efficiently represent control information for multiple illumination devices simultaneously. This multi-functional data structure adapts to different lighting scenarios and device configurations, providing efficient bandwidth utilization across diverse wireless network environments while preserving full control capabilities.
2Adaptability or versatility
If numerous illumination devices are controlled over wireless networks, then lighting system functionality is enhanced, but synchronization becomes difficult to maintain
Solution Approach 1:
The patent incorporates timing and synchronization information directly into the aggregated control data structure before transmission. This preliminary embedding of synchronization parameters ensures that all illumination devices can maintain precise coordination upon receiving the control data, eliminating synchronization difficulties that would otherwise arise from controlling numerous devices over wireless networks.
3Adaptability or versatility
If control data is transmitted to multiple illumination devices, then lighting scenarios can be implemented, but data transmission time increases
Solution Approach 1:
By merging control data for multiple devices into a single aggregated transmission, the patent reduces the total number of separate data transmissions required. This consolidation maintains the ability to implement complex lighting scenarios across multiple devices while significantly reducing the cumulative data transmission time compared to conventional individual device control methods.
