Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional panel light devices use fixed LED configurations, then manufacturing is simple, but flexibility in adjusting light parameters such as color temperature is limited
Solution Approach 1:
The LED package is divided into multiple sections, with each section containing LEDs of different types (e.g., warm white and cool white LEDs). This segmentation allows independent control of each section through separate driving currents, enabling flexible adjustment of color temperature and light parameters without requiring a completely complex device architecture.
Solution Approach 2:
The patent implements dynamic control of light parameters by allowing the driver to adjust the ratio of driving currents supplied to different LED sections in real-time. This dynamic current adjustment enables continuous variation of color temperature and light output, transforming a static lighting device into a dynamically adaptable system.
2Adaptability or versatility
If multiple LED types are used in separate sections with separate driving currents, then light parameter adjustability is improved, but device complexity increases
Solution Approach 1:
Multiple LED sections with different LED types are merged into a single integrated LED package structure. The driver circuit is designed to manage multiple LED types within one package, combining the functionality of what would otherwise be separate lighting devices into a unified, manageable unit that reduces overall system complexity.
Solution Approach 2:
The LED package is designed as a multi-functional unit that can produce various color temperatures and light parameters by combining different LED types (warm white, cool white, etc.) in separate sections. This universal design allows a single device to replace multiple specialized lighting devices, reducing the need for multiple separate components.
3Ease of operation
If separate driving currents are supplied to different LED sections, then color temperature control is enhanced, but manufacturing complexity increases
Solution Approach 1:
The LED package is segmented into distinct sections during manufacturing, with each section containing specific LED types and connected to separate driving current paths. This segmentation is built into the package structure itself, allowing independent current control to be achieved through straightforward manufacturing processes rather than complex post-assembly wiring.
Solution Approach 2:
The LED package structure is designed to self-organize the separate driving current paths through its internal architecture. The package housing and electrode arrangement automatically provide separate current pathways to different LED sections, reducing the need for complex external wiring and simplifying the manufacturing process while maintaining color temperature control capability.
