Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the projecting unit projects visible light onto regions emitting non-visible light, then the visibility of affected areas is improved, but the color selection becomes complex and difficult to operate
Solution Approach 1:
The control unit applies different color selection rules to different regions: for regions emitting non-visible light (first region), the system provides guided color selection from preset options, while for other regions (second region), the operator has full color selection freedom. This localized differentiation simplifies operation for critical regions while maintaining flexibility elsewhere.
Solution Approach 2:
The system automatically detects non-visible light emission and proactively guides color selection for affected regions, reducing the operator's cognitive burden. The control unit self-manages the complexity by automatically identifying which regions need special color selection guidance and which don't.
2Adaptability or versatility
If multiple color options are provided for projection, then the adaptability to different surgical needs is improved, but the device complexity increases
Solution Approach 1:
The control unit segments color options into different categories: preset color options for regions emitting non-visible light, and full color spectrum for other regions. This segmentation allows the system to provide adaptability where needed while maintaining simplicity where standard operation suffices.
Solution Approach 2:
The system dynamically adjusts the available color options based on the detected non-visible light emission. When a region is detected as emitting non-visible light, the control unit activates guided color selection from preset options; otherwise, full color selection is available. This dynamic adaptation provides versatility without permanent complexity.
3Ease of operation
If the control unit provides guided color selection from preset options, then the ease of operation is improved, but the adaptability to specific surgical requirements decreases
Solution Approach 1:
The control unit serves multiple functions: it provides guided preset color selection for simplicity when dealing with non-visible light emitting regions, and enables full color customization for adaptability when dealing with other regions. This multi-functionality resolves the contradiction by providing both simplicity and versatility as needed.

AI summary
A visible light projection device includes a detecting unit that detects a first region emitting non-visible light, a projecting unit that performs projection using visible light onto a second region including the detected first region, and a control unit that controls the projecting unit to perform projection with a color selected by an operator. When a first color is selected as a color of visible light projected by the projecting unit onto a region other than the first region within the second region, the control unit informs the operator of first options in such a way as to allow a color of visible light projected onto the first region by the projecting unit to be selected from the first options. When a second color different from the first color is selected as a color of visible light projected by the projecting unit onto a region other than the first region within the second region, the control unit informs the operator of second options different from a combination of candidates included in the first options in such a way as to allow a color of visible light projected onto the first region by the projecting unit to be selectable from the second options.
