Plastically Deformable Wound Care Article for Deep Wounds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wound care articles are unsuitable for deep wounds and complex body topographies, requiring cumbersome handling and potentially leading to sepsis issues, as they are designed for flat wounds and lack adaptability to irregular anatomical shapes.
Innovation Solution
A wound care article with a flat layer of absorbent material and an active element that is plastically deformable, allowing it to be shaped to fit various wound topologies, eliminating the need for additional fillers and enhancing absorption by bringing superabsorbent polymers close to the wound site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flat wound care product is used, then it is suitable for shallow wounds and flat body topography, but it cannot effectively treat deep wounds or adapt to complex body topography
Solution Approach 1:
The wound care product incorporates a plastically deformable reinforcement element that allows the product to be dynamically shaped from flat to convex or concave forms. This enables adaptation to various wound depths and body topographies while maintaining structural integrity during application and use.
Solution Approach 2:
The reinforcement element is designed with specific material properties (plastic deformability) that allow permanent shape changes. The material can be deformed plastically to create convex shapes for deep wounds or concave shapes for body contours, fundamentally changing the product's geometric parameters to match wound requirements.
2Volume of moving object
If additional wound fillers are used for deep wounds, then the wound can be filled, but the handling becomes cumbersome and absorbency may be impaired
Solution Approach 1:
The invention merges the wound filling function with the absorbent wound care product itself. The plastically deformable reinforcement allows the single product to perform both filling and absorbing functions, eliminating the need for separate filler materials and simplifying the application process.
Solution Approach 2:
The wound care product is designed as a multi-functional element that can simultaneously fill deep wounds and absorb exudate. The plastically deformable structure enables it to adapt to various wound depths while maintaining its absorbent capabilities, making it a universal solution for different wound types.
3Volume of moving object
If wound fillers are used, then deep wounds can be filled, but the superabsorbent polymers are not brought close to the wound site
Solution Approach 1:
The invention combines the wound filling structure with the absorbent material containing superabsorbent polymers into a single integrated product. This ensures that the superabsorbent polymers are positioned directly at the wound site when the product is applied, maximizing their therapeutic effect.
4Strength
If a reinforcement is made visible on the surface, then it provides structural support, but it cannot come into contact with the wound and may cause irritation
Solution Approach 1:
The reinforcement element is designed with differentiated properties: the internal structure provides strength and plastic deformability, while the surface layer in contact with the wound is soft, elastic, and absorbent. This local differentiation ensures structural support without skin irritation.
Applied Scientific Principles

Function Achieved in This Case
The deformable wound care article effectively fills deep wounds, promotes wound healing by contacting large areas of the wound bed, and adapts to complex body shapes, reducing sepsis risks and improving comfort by avoiding skin irritation.
