Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydrogel-based wound dressings have poor mechanical properties and do not effectively maintain viscosity at body temperature, leading to suboptimal wound healing and convenience issues.
Innovation Solution
A hydrogel-based topical wound dressing comprising polyethylene glycol (PEG), white petrolatum, 1,2-hexandiol, ethylhexylglycerin, sodium hyaluronate, a protein extract obtained through a multi-step decellularization process, and purified water, which maintains viscosity across temperature changes and enhances wound healing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydrogel is used as the main material for wound dressing, then moisture retention and biocompatibility are improved, but mechanical properties and tensile strength deteriorate
Solution Approach 1:
The patent uses a composite material system combining hydrogel with other polymers and additives to achieve both high moisture retention and improved mechanical strength. The hydrogel network is integrated with reinforcing components that provide structural support while maintaining the hydrophilic properties necessary for wound healing.
2Ease of operation
If hydrogel viscosity is increased at room temperature for better application, then viscosity stability at body temperature deteriorates
Solution Approach 1:
The patent employs temperature-responsive polymer components that undergo controlled changes in their physical properties at different temperatures. These components are designed to maintain optimal viscosity at room temperature for easy application, then transition to a stable, less viscous state at body temperature to ensure proper spreading and retention without excessive thickness.
3Reliability
If protein extract is added to enhance wound healing effect, then risk of immune reactions and toxicity increases
Solution Approach 1:
The patent extracts and isolates specific beneficial protein components from natural sources while removing or neutralizing immunogenic elements. The protein extract is processed to retain only the therapeutic factors needed for wound healing, such as growth factors or enzymes, while eliminating proteins that could trigger immune responses or allergic reactions.
Solution Approach 2:
The patent uses the hydrogel matrix as an intermediary carrier that protects and delivers the protein extract in a controlled manner. The hydrogel structure shields the protein components from direct immune system recognition while allowing gradual release at the wound site, reducing the risk of immune reactions while maintaining therapeutic efficacy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dressing provides excellent wound healing, re-epithelialization, and angiogenesis effects while maintaining convenience due to stable viscosity at body temperature, and it does not cause toxicity or immune reactions.
Implementation Method 1
Hydrogel has a three-dimensional hydrophilic polymeric network structure with water as a dispersion medium, and may absorb a large amount of moisture
Implementation Method 2
The topical wound dressing has excellent wound healing, re-epithelialization, and angiogenesis effects
