Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED lighting systems use fixed non-modular components, then the system structure is simple, but the system lacks flexibility for changing lighting needs and is prone to failure
Solution Approach 1:
The lighting system is divided into modular components: a power supply unit and multiple interchangeable light boards, each containing LED arrays. This segmentation allows individual light boards to be replaced or reconfigured without affecting the entire system, providing flexibility while maintaining manageable complexity through standardized interfaces
Solution Approach 2:
The modular light boards are designed with universal connectors and standardized mounting mechanisms that allow them to be interchangeably coupled to the power supply unit. This universality enables different light board configurations to serve various lighting needs while using the same base infrastructure
2Reliability
If LED lighting systems use non-interchangeable components, then the manufacturing process is simple, but the system is prone to failure and difficult to maintain
Solution Approach 1:
By segmenting the lighting system into replaceable light boards with standardized connectors, the design improves reliability through modular redundancy. If one light board fails, only that module needs replacement rather than the entire system, and the standardized manufacturing of modular components maintains production efficiency
Solution Approach 2:
The modular design allows pre-manufactured light boards to be prepared in advance with standardized interfaces. This preliminary preparation of interchangeable modules ensures quick replacement during maintenance, improving system reliability without complicating the manufacturing process
3Adaptability or versatility
If LED lighting systems lack modular components, then the device structure is simple, but installation options and customization are limited
Solution Approach 1:
The lighting system employs dynamic, reconfigurable modular light boards that can be added, removed, or rearranged based on installation requirements. This dynamic modularity provides multiple installation options and customization capabilities while maintaining a relatively simple overall device structure through standardized mounting interfaces
4Illumination intensity
If LED lighting systems use high-power LEDs, then the light output is high, but the power consumption is high
Solution Approach 1:
The system combines multiple lower-power LEDs into arrays on each light board to achieve high overall light output. By merging the output of many 0.2-watt or less LEDs in series and parallel configurations, the system attains high illumination intensity while maintaining lower individual component power consumption and improved reliability
