Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-programmed lighting settings are used, then the device structure is simple, but the adaptability and atmospheric variety are limited
Solution Approach 1:
The lighting device enables LEDs to autonomously perform random lighting operations through an internal control unit that automatically determines flickering cycles and brightness levels without requiring external pre-programming, thereby achieving atmospheric variety while maintaining simple device structure
Solution Approach 2:
The control unit dynamically adjusts lighting parameters by randomly determining flickering cycles and brightness levels during operation, allowing the system to adapt to different atmospheric requirements without complex pre-programmed settings
2Adaptability or versatility
If random lighting operations are enabled, then atmospheric variety is improved, but the control complexity increases
Solution Approach 1:
The control unit achieves diverse lighting effects by randomly varying key parameters such as flickering cycle duration and brightness levels, enabling atmospheric variety through parameter modulation rather than complex control logic
3Adaptability or versatility
If flickering cycle and brightness are randomly determined, then lighting dynamics are enhanced, but the ability to create specific atmospheric effects is reduced
Solution Approach 1:
The control unit receives predetermined control signals that define target atmospheric effects in advance, then uses these signals to guide the random determination process of flickering cycles and brightness, ensuring that random variations remain within the desired atmospheric framework
