Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If side emitting fiber optic mesh or LED chip array is used, then the adhesive device can be compact and self-contained, but the UV radiation distribution becomes non-uniform
Solution Approach 1:
A light guiding layer is introduced as an intermediary component between the UV radiation source and the treated surface. This layer receives UV radiation from the source and guides/distributes it uniformly across the treatment area, mediating between the compact source design and the requirement for uniform radiation distribution.
Solution Approach 2:
The patent replaces direct mechanical/optical emission from side-emitting sources with a light guiding mechanism. Instead of relying on the inherent emission pattern of fiber optic meshes or LED arrays, the system uses a light guiding layer to control and distribute the radiation, substituting passive emission with active guidance.
2Productivity
If non-uniform UV radiation distribution occurs, then device structure can be simpler, but disinfection efficiency decreases
Solution Approach 1:
The light guiding layer acts as a mediator that transforms the non-uniform radiation output from simple sources into a uniform distribution pattern, enabling high disinfection efficiency without requiring complex multi-source arrangements.
Solution Approach 2:
The light guiding layer changes the spatial distribution parameter of UV radiation, transforming it from a concentrated or non-uniform pattern at the source to a uniform pattern across the treatment surface, thereby improving disinfection efficiency.
