Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If linear interpolation is used for color temperature transition, then the implementation is simple, but the transition cannot follow the color temperature curve and causes flickering
Solution Approach 1:
The patent applies curvature by replacing linear interpolation with a color temperature curve that follows the spectral characteristics. The curve is constructed using reference color temperature points and intermediate points, creating a non-linear transition path that matches the physical color temperature curve, thereby eliminating flickering while maintaining implementation feasibility.
2Device complexity
If linear interpolation is used for color temperature transition, then the method is simple to implement, but high frame rates are required to avoid flickering
Solution Approach 1:
By implementing a color temperature curve that follows the spectral characteristics, the patent enables smooth transitions that are perceptually accurate. This curved approach reduces the required frame rate because the transition naturally follows the human visual system's perception of color temperature changes, eliminating the need for high frame rates to prevent flickering.
3Reliability
If a color temperature curve is fitted using multiple reference points and intermediate points, then smooth transitions without flickering are achieved, but the computational complexity increases
Solution Approach 1:
The patent segments the color temperature transition into discrete reference points and intermediate points. By dividing the transition path into manageable segments with predetermined points, the computational complexity is reduced while maintaining the accuracy of following the color temperature curve. This segmentation allows for efficient calculation and implementation.
Solution Approach 2:
The patent performs preliminary action by pre-defining reference color temperature points and intermediate points before the actual transition occurs. This pre-calculation approach stores the color temperature curve data in advance, reducing real-time computational requirements during actual color temperature transitions and thereby lowering operational complexity.
