Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only white light sources are used, then light output is maximized, but color temperature cannot be adjusted to match underwater depth conditions
Solution Approach 1:
The patent combines multiple light sources (white LED and colored LED) in a single underwater lighting device to achieve both high light output and adjustable color temperature. The white LED provides baseline illumination while the colored LED adds wavelength-specific light to adjust color temperature, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The patent changes the spectral composition parameter by varying the intensity ratio between white and colored light sources. This allows continuous adjustment of color temperature from warm to cool tones while maintaining high overall light output, enabling adaptation to different underwater depths without requiring multiple separate devices.
2Adaptability or versatility
If colored light sources are added to adjust color temperature, then color temperature control is improved, but light output may be reduced
Solution Approach 1:
By merging white and colored light sources, the system maintains high light output through the white LED while using the colored LED only for spectral adjustment. The white LED compensates for any intensity loss from the colored LED, ensuring that color temperature control does not compromise overall illumination quality.
Solution Approach 2:
The system optimizes the intensity parameters of both light sources dynamically. The white LED provides the bulk of the light output while the colored LED intensity is adjusted to achieve desired color temperature without significantly reducing overall brightness. This parameter optimization allows simultaneous achievement of high light output and effective color temperature control.
3Adaptability or versatility
If multiple light sources are combined, then color temperature adjustment is enabled, but device complexity increases
Solution Approach 1:
The patent merges multiple light sources into a single integrated underwater lighting unit with a unified optical output. This consolidation provides lighting flexibility for different underwater conditions while keeping the overall device structure compact and manageable, avoiding the complexity of multiple separate devices.
Solution Approach 2:
The integrated lighting device performs multiple functions: providing high light output, adjusting color temperature, and adapting to different underwater depths all within a single device. This multi-functionality eliminates the need for separate devices for each function, reducing overall system complexity while maintaining lighting flexibility.

Data Source
AI summary
An underwater light device is disclosed. The underwater light device comprises at least one source of white light and at least one source of colored light. The light produced by the combination of the at least one source of white light and the at least one source of colored light has an altered color temperature value compared to the light produced by only the at least one source of white light. For example, the combination of the at least one source of white light and the at least one source of colored light may have a color temperature value that is decreased by about 1,000 kelvin to about 2,000 kelvin compared to light produced only by the at least one source of white light.
