Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional LED lighting is used, then energy efficiency and longevity are improved, but flexibility and adjustability of light output are limited
Solution Approach 1:
The patent divides the LED lighting system into multiple independently controllable LED modules (first LED module, second LED module, third LED module) with separate control circuits. Each module can be controlled individually to produce different light outputs, colors, and patterns, thereby achieving flexibility and adjustability while maintaining energy efficiency through selective operation of modules.
2Adaptability or versatility
If multiple LED modules with separate control are implemented, then flexibility and light quality are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple LED modules and their control circuits into a single integrated lighting apparatus. The control circuits are designed to work together within one device, allowing flexible light output adjustment while managing complexity through integration rather than separate standalone components.
Solution Approach 2:
The control circuits are designed to perform multiple functions: controlling individual LED modules, mixing light colors, adjusting brightness levels, and creating various lighting patterns. This multi-functionality reduces the need for separate specialized components, thereby managing device complexity while maintaining high adaptability.
