Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current collagen dressings for wound care, primarily derived from bovine sources, may not provide optimal healing support due to limitations in enhancing the wound healing process.
Innovation Solution
A conformable wound dressing comprising a mixture of collagen, bioactive glass, and an additive of cellulose and/or alginate, which releases calcium ions to enhance healing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If collagen dressings are used for wound care, then wound healing is supported through cell attraction and tissue generation, but the healing enhancement is insufficient without additional active components
Solution Approach 1:
The patent combines collagen with bioactive glass particles to create a composite wound dressing material. The collagen provides the base structure for cell attachment and tissue generation, while the bioactive glass particles release calcium ions and other ions to enhance healing. This composite approach resolves the contradiction by integrating multiple functional components into a single dressing product that maintains structural simplicity while achieving superior healing effectiveness.
2Reliability
If bioactive glass is added to collagen to release calcium ions, then wound healing is enhanced, but the manufacturing process becomes more complex
Solution Approach 1:
The bioactive glass particles are pre-loaded with calcium ions and other beneficial ions during the dressing manufacturing process. This preliminary preparation allows the ions to be released gradually at the wound site without requiring complex activation mechanisms or additional processing steps during application. The dressing is prepared in advance with all necessary healing components integrated, simplifying the overall manufacturing while ensuring effective ion release at the wound site.
3Adaptability or versatility
If the dressing structure is made conformable to fit wound contours, then wound coverage is improved, but the structural stability may be compromised
Solution Approach 1:
The patent employs a thin film or mat structure made from the collagen-bioactive glass composite that is inherently flexible and conformable. This thin film structure can easily adapt to various wound contours and shapes while maintaining sufficient structural stability to remain intact during application and wear. The flexibility is achieved through the natural properties of the collagen matrix and the distributed reinforcement from embedded bioactive glass particles, resolving the contradiction between conformability and structural integrity.
