Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional strip lighting systems are used without modularity, then the system structure is simple, but the reliability of power supply deteriorates when constant power source is not available
Solution Approach 1:
The lighting system is divided into modular segments where each module contains its own power rail connection points. These modules can be connected in series to form extended lighting arrangements, allowing the system to maintain functionality even if one module loses power connection, thus improving reliability through modular architecture.
Solution Approach 2:
Rechargeable batteries are pre-installed within the lighting modules and automatically charge when the system is connected to external power. This preliminary energy storage ensures that illumination continues uninterrupted when external power fails, resolving the contradiction between reliability and complexity.
2Adaptability or versatility
If conventional strip lighting systems are used without power switching capability, then the device complexity is low, but the adaptability to different power sources deteriorates
Solution Approach 1:
The power management system dynamically switches between external power input and internal battery power based on availability. The system automatically detects power source status and transitions between charging mode and battery-powered mode, providing adaptability to different power sources while managing complexity through automated control logic.
Solution Approach 2:
The power rail serves multiple functions: it provides power distribution to LEDs, enables charging of rechargeable batteries, and facilitates communication between modules. This multi-functionality allows the system to adapt to various power sources and operational modes without requiring separate dedicated circuits for each function.
3Illumination intensity
If conventional strip lighting systems are used without uniform power distribution, then the manufacturing complexity is low, but the illumination uniformity deteriorates
Solution Approach 1:
The power distribution system is segmented into multiple connection points along the power rail, with each module receiving power independently. This segmentation ensures uniform voltage distribution across the lighting system, preventing voltage drops and ensuring consistent illumination intensity throughout the entire assembly.
Solution Approach 2:
The power rail acts as an intermediary component that distributes power uniformly to multiple LED modules. By introducing this dedicated power distribution infrastructure with multiple tap points, the system achieves uniform illumination without requiring complex manufacturing processes, as the power rail serves as a central mediating element for power allocation.
