Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound care systems lack the ability to efficiently flush, disinfect, and provide nutrient supply, temperature control, oxygenation, pH regulation, electrolyte replacement, and detoxification without removing bandages, while also facilitating the introduction of growth factors and antibiotics in a safe and easy manner.
Innovation Solution
A pouch-shaped wound dressing system with a planar capillary membrane system that allows for the introduction and removal of liquids, gases, and substances through a supply line, enabling intermittent or continuous nutrient supply and exudate suction, with capillary membranes designed for high permeability and adaptable configurations for different wound sizes and treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional wound dressing system is used, then the wound can be covered and protected, but it cannot efficiently flush, disinfect, provide nutrient supply, temperature control, oxygenation, pH regulation, electrolyte replacement, and detoxification without removing bandages
Solution Approach 1:
The capillary membrane system is designed to perform multiple wound care functions simultaneously: flushing, disinfection, nutrient supply, temperature control, oxygenation, pH regulation, electrolyte replacement, and detoxification. This multi-functional approach resolves the contradiction by enabling diverse treatment capabilities through a single integrated system rather than requiring multiple separate devices or procedures
Solution Approach 2:
The system divides the wound care functions into separate controllable components: a pump for liquid introduction, a vacuum unit for exudate removal, and a capillary membrane system for substance delivery. This segmentation allows each component to be optimized for its specific function while working together as an integrated system, managing complexity through modular design
2Manufacturing precision
If a capillary membrane system is introduced into the wound, then uniform material distribution and efficient substance delivery are achieved, but the system requires complex supply lines and connection to external units
Solution Approach 1:
The capillary membrane system acts as an intermediary between the external supply lines and the wound tissue. The membranes receive substances through supply lines and automatically distribute them uniformly across the wound area through capillary action, eliminating the need for complex direct connection systems while maintaining precise material distribution
Solution Approach 2:
The system uses a pump to introduce liquids and a vacuum unit to remove exudates, creating controlled fluid flow through the capillary membrane system. This hydraulic approach enables precise substance delivery and uniform distribution without requiring complex mechanical positioning or multiple connection points
3Productivity
If the pouch-shaped wound dressing is used with permeable lower face, then efficient exudate removal and substance delivery are achieved, but the structural integrity and containment capability are reduced
Solution Approach 1:
The pouch structure is designed with differentiated properties: the lower face is made permeable for exudate removal and substance delivery, while the upper face and side walls maintain higher structural integrity for containment. This local quality differentiation resolves the contradiction by providing both permeability where needed and strength where required within the same structure
Solution Approach 2:
The lower face of the pouch utilizes porous or semi-permeable material that allows selective passage of exudates and therapeutic substances while maintaining structural form. The porous structure enables efficient exudate removal through capillary action and pressure gradients without compromising the overall pouch integrity
4Adaptability or versatility
If intermittent or continuous treatment is provided through the supply line, then flexible wound care protocols are enabled, but the control mechanism and monitoring requirements increase
Solution Approach 1:
The system enables dynamic treatment protocols by allowing switching between intermittent and continuous operation modes through the pump and vacuum unit controls. The capillary membrane system automatically adjusts substance delivery based on the operational mode, providing treatment flexibility without requiring complex manual intervention or monitoring systems
