Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If different translucent media with different manufacturing techniques are used, then the media can be produced with varying characteristics, but the color temperature becomes inconsistent across different media
Solution Approach 1:
The system changes the parameters of the light sources (intensity, wavelength distribution) to compensate for variations in media properties. By adjusting the spectral power distribution of the illuminating light, the system maintains consistent color temperature output despite differences in media manufacturing techniques and resulting optical characteristics.
Solution Approach 2:
The system employs feedback control by measuring the actual color temperature of the displayed media and adjusting the light source intensities accordingly. Sensors detect the output color temperature, and the controller modifies the light source parameters to achieve the target color temperature, ensuring consistency across different media types.
2Stability of the object's composition
If manual adjustment of light sources is used to achieve consistent color temperature, then color consistency can be maintained, but the adjustment process becomes time-consuming and complex
Solution Approach 1:
The system uses automated feedback control where sensors continuously measure the color temperature of the light passing through the media, and the controller automatically adjusts the light source intensities to maintain the target color temperature. This eliminates manual adjustment time and provides consistent results.
Solution Approach 2:
The system performs self-adjustment by using its own sensors to detect color temperature deviations and automatically correcting them through controller-driven light source modulation. The system serves itself by autonomously maintaining color consistency without external intervention.
3Adaptability or versatility
If multiple light sources with different peak wavelengths are used, then color temperature tuning capability is enhanced, but the system complexity increases
Solution Approach 1:
The system divides the illumination into multiple discrete light sources, each with a specific peak wavelength. By segmenting the spectrum into manageable wavelength bands, the system can independently control each source to synthesize the desired color temperature, making the complexity manageable through modular organization.
Solution Approach 2:
The system exploits parameter changes in the light sources (specifically wavelength and intensity) to achieve color temperature tuning. By varying the intensity ratios of light sources with different peak wavelengths, the system can continuously adjust the overall color temperature to match different ambient lighting conditions.
4Reliability
If the light box is designed to work with a specific media type, then performance is optimized for that media, but adaptability to different media types is reduced
Solution Approach 1:
The system is designed with universal applicability by incorporating multiple light sources with different spectral characteristics and using automated control. This multi-functional design allows the same light box to effectively illuminate various types of translucent media (vinyl, fabric, paper, foam board) by adjusting the light source parameters to match each media's optical properties.
Solution Approach 2:
The system adapts to different media types by changing the parameters of the light sources. By measuring the actual output with sensors and adjusting the intensity and spectral distribution of the light sources, the system maintains optimal performance across diverse media types without requiring hardware modifications.
