Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear filters for fluorescent emission technology (FET) in medical and dental fields obstruct ambient light viewing while isolating fluorescent light, preventing practitioners from seeing both types of light simultaneously.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a filter is employed to isolate fluorescent light from excitation light, then fluorescent light detection is improved, but ambient light viewing is blocked
Solution Approach 1:
The filter assembly is designed to be movable and switchable between different positions. The filter can be dynamically inserted or removed from the optical path, allowing the practitioner to switch between fluorescent light detection mode and ambient light viewing mode. This dynamic configuration resolves the contradiction by making the filtering function conditional rather than permanent.
Solution Approach 2:
The eyewear system is segmented into separate functional components: the base eyewear structure, the removable filter assembly, and the mounting mechanism. This segmentation allows the filter to be independently controlled and positioned, enabling selective application of the filtering function only when fluorescent light detection is required, thereby preserving ambient light viewing capability when the filter is retracted.
2Measurement precision
If a filter is permanently attached to eyewear for FET, then fluorescent light isolation is improved, but flexibility and adaptability are reduced
Solution Approach 1:
The filter assembly incorporates a magnetic mounting mechanism that enables dynamic attachment and detachment. The filter can be easily mounted when needed for fluorescent light isolation and removed or repositioned when ambient light viewing is required, providing adaptability without compromising the effectiveness of fluorescent light isolation when the filter is in place.
Solution Approach 2:
The eyewear system is designed to support multiple functions through a universal mounting structure. The same magnetic mounting mechanism accommodates both the filter assembly for fluorescent light detection and allows the eyewear to function normally for ambient light viewing. This multi-functionality resolves the contradiction by making the system adaptable to different operational requirements.
3Device complexity
If a filter assembly is added to eyewear for light filtering, then device complexity is reduced through magnetic attachment, but manufacturing complexity increases
Solution Approach 1:
The traditional mechanical attachment mechanisms (screws, clips, adhesives) are replaced with a magnetic mounting system. This substitution simplifies the user interaction and assembly process while the manufacturing complexity is managed through standardized magnetic components and pre-fabricated filter assemblies that can be produced using conventional manufacturing techniques.
