Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If LED lighting systems use AC power during peak demand periods, then lighting operation is maintained, but energy consumption and costs increase
Solution Approach 1:
The system performs preliminary charging of the battery during off-peak hours when AC power is abundant and costs are lower. This stored energy is then utilized during peak demand periods to maintain lighting operation without drawing from the AC grid, thereby resolving the contradiction between reducing peak energy consumption and maintaining lighting reliability.
Solution Approach 2:
The system changes the power source parameter dynamically - switching from AC power during off-peak periods to battery power during peak periods. This parameter change allows the system to optimize energy consumption patterns while maintaining continuous lighting operation, addressing both the energy cost and reliability concerns.
2Use of energy by stationary object
If LED lighting systems disconnect from AC power during outages, then energy consumption from grid is reduced, but lighting operation is interrupted
Solution Approach 1:
The battery is preliminarily charged during normal AC power operation. When AC power fails, this pre-stored energy automatically takes over to maintain lighting operation, eliminating any interruption while ensuring grid energy consumption is reduced to zero during outages.
Solution Approach 2:
The battery acts as an intermediary power source between the AC grid and the LED lighting system. During AC outages, this intermediary provides the necessary power transfer, ensuring continuous lighting operation while completely disconnecting from the unstable AC grid, thus resolving both energy consumption and reliability requirements.
3Adaptability or versatility
If wireless control and power system is implemented, then installation flexibility and energy management capability are improved, but device complexity increases
Solution Approach 1:
The wireless control module serves multiple functions: it enables remote on/off control, dimming adjustments, power consumption monitoring, and coordination with the battery management system. This multi-functionality achieves high installation flexibility and energy management capability while minimizing the addition of separate components, thereby addressing the adaptability improvement without excessive complexity increase.
Solution Approach 2:
The wireless control and power management functions are merged into an integrated system that coordinates AC power input, battery charging/discharging, and LED driver control. This consolidation achieves versatile installation options and comprehensive energy management while reducing the complexity that would result from separate independent systems.
