Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If network density is increased to improve sensitivity and accuracy, then sensing performance improves, but system complexity and cost increase
Solution Approach 1:
The patent applies parameter changes by adjusting operating variables of existing network devices (transmission power, signal processing parameters, modulation schemes) to enhance sensitivity and accuracy without adding more devices. The configuration module modifies these parameters based on network conditions and device capabilities, achieving improved measurement precision while maintaining the same network density.
2Measurement precision
If additional light modules are added to improve sensing accuracy, then network sensitivity increases, but installation complexity and cost increase
Solution Approach 1:
The system implements self-service by automatically configuring and optimizing the performance of existing light modules through the configuration module. The system self-adjusts operating variables based on network information and performance requirements, eliminating the need for manual installation of additional modules while achieving improved sensing accuracy.
3Reliability
If light modules are redistributed to improve sensing coverage, then network performance improves, but deployment complexity increases
Solution Approach 1:
The patent applies dynamics by enabling real-time adjustment of operating variables in response to changing network conditions and environmental factors. The configuration module dynamically optimizes parameters such as transmission power and signal processing settings, allowing the system to adapt to different spatial configurations without requiring physical redistribution of light modules.
