Perforated Stratiform Biomatrix for Wound Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stratiform biomatrices for wound treatment lack sufficient flexibility and spatial modeling capability, making it difficult to achieve complete and homogeneous coverage of deep and irregularly shaped wound cavities, and they often require mechanical cutting tools for adaptation, which is labor-intensive and risky.
Innovation Solution
The development of stratiform biomatrices formed from regularly shaped, evenly arranged portions connected by continuous, straight-through perforations, allowing for easy tearing and resizing without cutting tools, enhancing flexibility and spatial modeling capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stratiform biomatrices are made from continuous homogeneous material, then structural integrity is maintained, but flexibility and spatial modeling capability are insufficient
Solution Approach 1:
The biomatrix is divided into multiple regularly shaped portions (e.g., squares, rectangles, triangles) connected by perforations. This segmentation allows the material to be flexed and molded into three-dimensional configurations while maintaining structural integrity through the connected portions, directly resolving the contradiction between flexibility and structural strength.
2Ease of operation
If stratiform biomatrices are made as single piece, then application is simple, but adaptation to irregular wound shapes requires mechanical cutting tools
Solution Approach 1:
The perforated design allows the biomatrix to be easily torn or cut into custom shapes by hand without requiring mechanical cutting tools. The regular portions connected by perforations provide natural separation lines that guide easy division, enabling safe adaptation to irregular wound shapes while minimizing the risk of infection and injury from tool use.
Solution Approach 2:
The perforations are pre-formed during manufacturing to create natural separation lines. This preliminary action prepares the biomatrix for easy custom shaping at the point of use, eliminating the need for mechanical cutting tools and reducing the risk of infection and injury during adaptation to irregular wound shapes.
3Productivity
If stratiform biomatrices have fixed size and shape, then manufacturing is efficient, but customization to different wound sizes is difficult
Solution Approach 1:
The biomatrix is manufactured as a sheet with regularly spaced perforations that create uniform portions. This segmentation allows efficient manufacturing of standardized sheets while enabling easy customization to different wound sizes by simply tearing or cutting along the perforation lines, maintaining both manufacturing efficiency and adaptability.
Solution Approach 2:
The perforations are pre-formed during manufacturing to create natural separation lines. This preliminary action prepares the biomatrix for easy custom sizing at the point of use, allowing efficient manufacturing of standardized sheets that can be readily adapted to different wound dimensions without requiring complex custom manufacturing processes.
