Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If light sources are arranged in an array with multiple rows and columns to cover a broader area, then the light coverage area is improved, but the alignment precision of light rays may deteriorate
Solution Approach 1:
The optical assembly is segmented into multiple light sources arranged in rows and columns, each with its own collimating lens. This segmentation allows independent optimization of each light source's alignment while collectively covering a broader area, resolving the contradiction between area coverage and alignment precision.
Solution Approach 2:
Each light source in the array is equipped with a collimating lens that provides localized collimation and alignment optimization for that specific position. This local quality approach ensures that each segment of the light array maintains precise alignment while the overall array covers a larger area.
2Manufacturing precision
If a collimating lens is used to align light rays in a specific direction, then the light ray alignment is improved, but the light distribution uniformity may worsen
Solution Approach 1:
The patent introduces a diffuser element that operates in a different optical dimension than the collimating lens. While the lens works in the directional dimension to align rays, the diffuser works in the spatial distribution dimension to uniformize the light pattern, thereby resolving the contradiction between alignment and uniformity.
Solution Approach 2:
A diffuser element is introduced as an intermediary component between the collimating lens and the target area. This intermediary softens the highly directional collimated light and redistributes it more uniformly across the treatment area, maintaining alignment while improving uniformity.
3Adaptability or versatility
If multiple light sources with different wavelengths are used to treat various medical indications, then the treatment versatility is improved, but the device complexity increases
Solution Approach 1:
The optical assembly is designed with a universal structure that can accommodate multiple light sources emitting at different wavelengths. The collimating lens and diffuser configuration works effectively for various wavelengths, allowing a single device design to provide multi-wavelength treatment capabilities without proportionally increasing complexity.
Solution Approach 2:
Multiple light sources with different wavelengths are merged into a single array configuration with a unified optical path through the collimating lens and diffuser. This combining approach allows diverse wavelength treatments to be delivered through a single integrated device rather than requiring separate devices for each wavelength.
