Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eyewear lenses fail to effectively enhance the visibility of colored objects such as blood-trails and orange clay discs, especially under varying lighting conditions, leading to difficulties for hunters and shooters in tracking targets.
Innovation Solution
The development of an optical filtering apparatus with distinct global, local, and color-balance attenuations that combine to improve the visibility of specified colors, featuring a general shading effect, targeted wavelength suppression, and color-shift enhancement, while maintaining natural background appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If simple colored tinting lenses are used, then general shading effect is provided, but visibility enhancement of specific colored objects is insufficient
Solution Approach 1:
The optical filter is divided into multiple distinct attenuation regions: a first attenuation region for wavelengths contributing to the target color, a second attenuation region for wavelengths not contributing to the target color, and a third attenuation region for color balance. This segmentation allows each region to perform its specific function independently, achieving both shading and color contrast enhancement simultaneously.
Solution Approach 2:
Different portions of the optical spectrum are treated with different attenuation characteristics. The first attenuation region provides strong attenuation for color enhancement, the second provides moderate attenuation for shading, and the third provides selective attenuation for color balance. This local differentiation of optical properties resolves the contradiction between general shading and specific color visibility.
2Loss of information
If complex manipulations of visible light spectrum are applied, then visibility of colored objects is enhanced, but natural appearance of background is altered
Solution Approach 1:
The optical filter applies different attenuation characteristics to different wavelength regions: the first attenuation region (450-650nm) enhances target color contrast, the second attenuation region (650-750nm) provides moderate shading, and the third attenuation region (380-450nm) provides selective color balance attenuation. This localized differentiation allows color enhancement while preserving natural background appearance.
Solution Approach 2:
The attenuation parameters are specifically optimized for different wavelength regions to achieve the desired effect. The first region uses high attenuation (0.3-2.0) for color contrast, the second uses moderate attenuation (0.1-0.5) for shading, and the third uses selective attenuation (0.05-0.3) for color balance. These parameter changes enable enhanced visibility without excessive background distortion.
3Illumination intensity
If strong attenuation is applied to all wavelengths, then general shading is achieved, but visibility of specific colors is not significantly improved
Solution Approach 1:
The optical filter is segmented into three distinct attenuation regions with different attenuation characteristics. The first region (450-650nm) provides strong attenuation to enhance target color contrast, the second region (650-750nm) provides moderate attenuation for general shading, and the third region (380-450nm) provides selective attenuation for color balance. This segmentation prevents uniform attenuation from washing out color differentiation.
Solution Approach 2:
Different wavelength regions receive different levels of attenuation tailored to their specific function. The first region receives strong attenuation for color contrast enhancement, the second receives moderate attenuation for general shading, and the third receives selective attenuation for color balance. This local quality differentiation ensures that color information is preserved while achieving overall shading.
