Recyclable Thin-Film Cell Matrix for Low-Cost Expandable Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing expandable cell matrices used in various applications are costly and not recyclable, particularly problematic in healthcare settings where contamination occurs, necessitating the development of affordable, recyclable, and disposable alternatives.
Innovation Solution
Manufacturing expandable cell matrices using recyclable thin films, specifically by creating a plurality of interconnected cells through folding and sealing processes, allowing the structures to expand into a container form upon fluid introduction, with methods including cross-web, gusset, and vertical sealing techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If dip molding, vacuum forming, and cast molding of PVC vinyls and polyurethanes are used to manufacture cell matrices, then the structural integrity and durability are improved, but the manufacturing cost increases and the material becomes non-recyclable
Solution Approach 1:
The patent changes the material parameters from traditional PVC vinyls and polyurethanes to thin-film materials that are recyclable and cost-effective, while maintaining the structural integrity needed for cell matrix functionality through optimized film properties and sealing parameters
Solution Approach 2:
The patent adopts disposable thin-film cell matrices that can be manufactured at lower cost and discarded after use in healthcare settings, replacing expensive and non-recyclable traditional materials with affordable, single-use alternatives
2Duration of action of stationary object
If traditional PVC materials are used in healthcare settings, then the structural durability is improved, but the environmental impact worsens due to non-recyclability and contamination disposal requirements
Solution Approach 1:
The patent implements a disposable approach where thin-film cell matrices are discarded after single use in healthcare settings, eliminating the need for cleaning and sterilization, and enabling proper waste disposal that reduces environmental impact compared to non-recyclable PVC materials
Solution Approach 2:
The patent employs single-use thin-film cell matrices that prevent cross-contamination in healthcare applications while being environmentally friendly and recyclable, replacing durable but harmful traditional materials
3Strength
If thick materials are used to ensure durability, then the strength is improved, but the storage space requirement increases and the ease of operation deteriorates
Solution Approach 1:
The patent uses thin-film materials to construct cell matrices that can be easily stored, transported, and deployed, providing the necessary strength and durability through optimized film properties rather than material thickness, thereby improving portability and ease of operation
