Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional light source is used without spectral modulation, then the system is simple and easy to operate, but it cannot effectively influence consumer visual perception and shopping behavior
Solution Approach 1:
The illumination system dynamically adjusts the spectral power distribution of the light source in real-time based on the object's reflection spectrum and target visual perception requirements. The algorithm unit continuously processes spectral data and modifies control signals to the light source, enabling adaptive spectral modulation that responds to changing illumination conditions and object characteristics
Solution Approach 2:
The system changes the spectral parameters of the illumination beam by modulating the spectral power distribution across different wavelengths. The algorithm unit calculates required spectral adjustments and the light source implements these changes by varying intensity at different spectral bands, thereby transforming the physical parameters of the light to achieve target visual perception
2Reliability
If the illumination system modulates spectra according to reflection spectrum and visual preferences, then consumer experience is enhanced, but the algorithm processing and control complexity increases
Solution Approach 1:
The algorithm unit implements a feedback mechanism by continuously analyzing the object's reflection spectrum and comparing it against target visual perception criteria. Based on this feedback, the system adjusts the spectral power distribution in real-time, creating a closed-loop control system that ensures accurate visual perception rendering while adapting to different objects and lighting conditions
Solution Approach 2:
The system performs preliminary spectral analysis of the object's reflection characteristics before full illumination modulation. The algorithm unit pre-calculates the required spectral adjustments based on the measured reflection spectrum and target visual perception requirements, preparing control signals in advance to optimize the illumination beam before actual display
3Adaptability or versatility
If multiple light sources with different spectra are used, then diverse visual perceptions can be achieved, but the system complexity and energy consumption increase
Solution Approach 1:
The illumination system segments the spectral output into multiple independent controllable bands or channels. Each light source or LED within the system can be independently controlled to emit at specific spectral ranges, allowing selective activation of only the necessary spectral segments required for the current illumination task, thereby reducing overall energy consumption while maintaining spectral diversity
