Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current photodynamic therapy technologies face challenges in effectively transmitting light to cancerous tissues, particularly for treating metastatic brain tumors, due to the need for stable light transmission through living tissues.
Innovation Solution
A light-guiding adhesive patch is developed, comprising an adhesive patch portion with a light guide layer and a light-transmitting portion connected to guide light from an external source to the adhesive patch portion, ensuring strong adhesion and efficient light transmission to organic matter surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light-transmitting device is applied to treat cancerous tissues, then light transmission to the treatment site is improved, but stable adhesion to organic matter surfaces is insufficient
Solution Approach 1:
The adhesive patch integrates multiple functional layers including a light-transmitting portion (transparent or translucent material), an adhesive portion (adhesive layer and core layer), and a light guide layer. This composite structure combines the light transmission capability of transparent materials with the adhesion properties of adhesive layers, resolving the contradiction between light transmission and adhesion stability.
Solution Approach 2:
The adhesive layer and core layer serve as intermediary components between the light-transmitting portion and the organic matter surface (skin, tissue). These intermediate layers provide both mechanical adhesion to the surface and optical transmission pathways, enabling stable attachment while maintaining light delivery to the treatment site.
2Illumination intensity
If a light-guiding adhesive patch is designed with multiple layers, then light transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The adhesive patch is segmented into distinct functional layers: a light-transmitting portion for optical delivery, an adhesive portion comprising adhesive layer and core layer for attachment, and a light guide layer for light distribution. This segmentation allows each layer to be optimized for its specific function while maintaining overall system effectiveness.
Solution Approach 2:
The adhesive patch integrates multiple functions into a single device: light transmission, light guidance, adhesion to organic surfaces, and mechanical support. By combining these functions into one multi-functional device, the patent avoids the complexity of using separate components for each function.
