Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional fluorescent lighting devices are left on continuously to meet legal illumination requirements, then proper illumination is maintained, but energy consumption increases significantly
Solution Approach 1:
The lighting system dynamically adjusts its operation mode based on detected conditions. The processor controls the LED strip to provide full illumination when needed (e.g., during emergency situations) and reduced illumination or standby mode during normal conditions, allowing the system to adapt between continuous illumination requirements and energy-saving operations
Solution Approach 2:
The system changes operational parameters such as illumination intensity and power consumption levels. By controlling the LED strip's power delivery, the system can operate at different intensity levels depending on whether full illumination is required or energy conservation is prioritized, directly addressing the contradiction between maintaining illumination and reducing energy use
2Use of energy by moving object
If existing lighting fixtures are replaced to improve energy efficiency, then energy consumption is reduced, but installation costs and disruption increase
Solution Approach 1:
The system segments the lighting functionality into a separate controllable LED strip module that can be integrated into existing fixtures. This allows the lighting upgrade to be applied as a discrete component rather than requiring complete fixture replacement, reducing installation complexity and cost while maintaining energy efficiency
Solution Approach 2:
The control board acts as an intermediary between the power source and the LED strip, enabling intelligent power management. This intermediary component allows the system to achieve energy efficiency through smart control rather than complete system replacement, reducing installation requirements
3Loss of energy
If lighting devices are controlled to save energy, then operational costs decrease, but compliance with legal lighting requirements becomes difficult to maintain
Solution Approach 1:
The system incorporates feedback mechanisms where the processor monitors conditions and adjusts lighting operation accordingly. This feedback control ensures that illumination requirements are met when legally required while maximizing energy savings during periods when full illumination is not mandated, maintaining compliance while optimizing energy use
Solution Approach 2:
The lighting system dynamically adjusts its operation mode based on detected conditions. The processor controls the LED strip to provide full illumination when needed (e.g., during emergency situations) and reduced illumination or standby mode during normal conditions, allowing the system to adapt between continuous illumination requirements and energy-saving operations
