Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing illumination systems use fixed spectrum light sources, then the system structure is simple, but the ability to create targeted visual perceptions is insufficient
Solution Approach 1:
The illumination system dynamically adjusts the spectral power distribution of the light source in real-time based on object characteristics and desired visual perceptions. The algorithm unit continuously processes reflection spectrum data and generates control signals that modulate the illumination beam spectrum, transforming a static lighting system into an adaptive one that can create different visual effects for different objects
Solution Approach 2:
The system changes the spectral parameters of the illumination beam by modulating the intensity of different wavelength components. The algorithm unit calculates the required spectral power distribution at multiple wavelengths based on the object's reflection spectrum and the target visual perception, then adjusts the light source output accordingly to achieve the desired color appearance
2Measurement precision
If the illumination system modulates the spectrum based on reflection spectrum and visual preferences, then the visual perception accuracy is improved, but the computational complexity increases
Solution Approach 1:
The system performs preliminary calculations of the required spectral power distribution before actual illumination. The algorithm unit pre-computes the control signals needed to achieve the target visual perception based on the object's reflection spectrum and stored visual preference data, allowing the illumination system to execute the pre-planned spectral modulation without real-time computational delays
Solution Approach 2:
The system uses the object's reflection spectrum as feedback to adjust the illumination beam spectrum. The algorithm unit compares the measured or known reflection spectrum with the target visual perception requirements and continuously adjusts the spectral power distribution to minimize the difference, creating a closed-loop control system that improves visual perception accuracy
3Adaptability or versatility
If the light source outputs fixed spectrum illumination, then the energy consumption is low, but the consumer experience and mood influence capability is limited
Solution Approach 1:
The illumination system uses periodic or pulsed illumination at different wavelengths to probe the object's reflection characteristics and build its reflection spectrum. Instead of continuously illuminating at full power across all wavelengths, the system periodically switches between different wavelength components, reducing overall energy consumption while still gathering the necessary spectral information
Solution Approach 2:
The system changes the spectral parameters of the illumination beam by modulating the intensity of different wavelength components. The algorithm unit calculates the required spectral power distribution at multiple wavelengths based on the object's reflection spectrum and the target visual perception, then adjusts the light source output accordingly to achieve the desired color appearance
