Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized power supply and control units are used, then the lighting network structure is simplified, but the flexibility in varying intensity and color of each appliance source is reduced
Solution Approach 1:
The patent divides the centralized lighting network into autonomous segments by equipping each lighting appliance with its own solar panel, battery, and control unit. This segmentation allows each appliance to independently regulate its light intensity and color based on available energy and environmental conditions, resolving the contradiction between simplified structure and operational flexibility.
Solution Approach 2:
Each lighting appliance becomes self-sufficient by generating its own power through solar panels, storing energy in batteries, and autonomously controlling its lighting parameters. This self-service capability eliminates dependence on centralized control while maintaining flexibility in intensity and color variation across the network.
2Adaptability or versatility
If self-powered appliances with processing units are used, then flexibility in varying intensity and color is improved, but device complexity increases
Solution Approach 1:
The lighting appliance integrates multiple functions into a single device: solar panels for power generation, batteries for energy storage, RGB LEDs for variable color output, and processing units for autonomous control. This multi-functionality achieves operational flexibility without proportionally increasing complexity, as all components work together within a unified appliance structure.
Solution Approach 2:
The processing unit dynamically adjusts lighting parameters (intensity, color temperature, duration) based on battery charge levels and environmental luminosity. This parameter adaptation allows the system to maintain flexibility while managing complexity through intelligent control algorithms that optimize performance based on available resources.
3Use of energy by moving object
If energy accumulation based control is used, then energy efficiency is improved, but the control system complexity increases
Solution Approach 1:
The processing unit continuously monitors battery charge status and environmental luminosity levels, using this feedback to dynamically adjust lighting intensity, color, and operation duration. This feedback mechanism optimizes energy efficiency by matching lighting output to actual needs and available energy, while the control logic remains manageable through rule-based decision algorithms.
