Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple LED-based fixtures with different color temperatures are stocked to accommodate various customer preferences, then customer choice and satisfaction are improved, but inventory size and storage requirements increase
Solution Approach 1:
The patent applies universality by designing a single LED fixture that can perform multiple functions - specifically, it can emit light at different color temperatures (e.g., 2700K, 3000K, 3500K, 4000K) by selectively activating different LED groups. This multi-functionality eliminates the need to stock multiple separate fixtures for different color temperature preferences, thereby reducing inventory size while maintaining customer choice.
Solution Approach 2:
The patent applies dynamics by implementing a switching device that can dynamically reconfigure the connection of LED groups between series and parallel arrangements. This dynamic switching capability allows the fixture to adapt its color temperature output in real-time based on customer preference or application requirements, transforming a static single-color-temperature fixture into a dynamic multi-color-temperature solution.
2Adaptability or versatility
If multiple LED-based fixtures with different color temperatures are manufactured and stocked, then various color temperature requirements are met, but manufacturing costs and resource expenditures increase
Solution Approach 1:
The patent applies merging by combining multiple LED groups (first, second, third, and fourth LED groups) within a single fixture housing, along with integrating a switching device that can reconfigure these groups. This consolidation of multiple color temperature capabilities into one fixture reduces manufacturing costs compared to producing and stocking separate fixtures for each color temperature, while still providing diverse color temperature options to customers.
3Adaptability or versatility
If LED groups are connected in different configurations to achieve different color temperatures, then color temperature selectability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the LED lighting system into distinct, modular LED groups (first, second, third, and fourth LED groups) that can be independently controlled. Each LED group corresponds to a specific color temperature range. This segmentation allows the switching device to manage complexity by simply connecting or disconnecting predefined groups rather than managing individual LEDs, making the system easier to control while maintaining high adaptability.

AI summary
Certain aspects involve lighting systems in which the color temperature of the illumination can be selectively modified. In one example, a lighting system can include a set of light sources. The lighting system can also include a switching device. The switching device can connect different light sources from the set into light-source combinations having different color temperatures, respectively. A light-source combination can include two of the light sources connected in series.
