Light-Guiding Adhesive Patch for Metastatic Brain Tumor Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current photodynamic therapy technologies face challenges in effectively transmitting light to cancerous tissues, particularly in metastatic brain tumors, where the light-guiding capabilities are inadequate.
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 conventional adhesive patches are used, then adhesion to organic matter surfaces is achieved, but light transmission capability is insufficient
Solution Approach 1:
The patent combines the adhesive patch structure with light-guiding functionality into a single integrated device. The adhesive patch includes both adhesive layers for securing to tissue and light-guiding layers for transmitting light, merging two previously separate functions (adhesion and light guidance) into one unified structure that simultaneously achieves both objectives.
Solution Approach 2:
The adhesive patch employs composite material structure consisting of multiple layers with different properties: adhesive layers for bonding, light-guiding layers for light transmission, and potentially light-transmitting portions for enhanced optical performance. This composite structure allows the patch to exhibit both strong adhesion characteristics and effective light transmission capabilities that individual materials cannot achieve alone.
2Productivity
If light-guiding structures are added to improve light transmission, then photodynamic therapy efficacy is enhanced, but device complexity increases
Solution Approach 1:
The adhesive patch is designed as a multi-functional device that simultaneously performs adhesion, light guidance, and light transmission functions. By making the patch universal in its capabilities, it eliminates the need for separate adhesive applications and light-guiding structures, thereby enhancing photodynamic therapy efficacy while avoiding the complexity increase that would result from adding separate components.
Solution Approach 2:
The patent divides the adhesive patch into distinct functional layers or portions, including adhesive layers and light-guiding layers. This segmentation allows each layer to be optimized for its specific function while maintaining overall integration, enabling effective light transmission for photodynamic therapy without creating an overly complex monolithic structure.
