Skin Straining Device for Wound Stress Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating scars and keloids are ineffective in preventing or ameliorating their formation, as they primarily focus on treating established scars rather than addressing the underlying mechanical environment that contributes to their development.
Innovation Solution
Devices and methods that apply and maintain strain, compression, or stress on the skin around a wound site using skin frames or straining devices to unload stress and reduce the mechanical environment, thereby inhibiting excessive scarring by controlling the mechanical forces acting on the wound during the healing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current scar treatment methods are used, then treatment of established scars is attempted, but they are ineffective in preventing or ameliorating scar formation
Solution Approach 1:
The patent applies preliminary action by implementing stress unloading measures immediately after wound closure, before hypertrophic scarring can develop. The splint or brace is applied during the proliferative stage to prevent the mechanical stress that would otherwise trigger excessive collagen production and scar formation, thereby preventing the problem rather than treating it after it occurs.
2Reliability
If skin straining devices are applied to unload stress at wound site, then scar formation is prevented, but device complexity increases
Solution Approach 1:
The patent employs flexible shells and thin films by using a splint or brace that conforms to the body contour and applies distributed mechanical stress to unload the wound site. This flexible approach achieves effective stress redistribution without requiring complex rigid mechanical structures, thereby maintaining simplicity while ensuring reliability in preventing hypertrophic scarring.
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 solution effectively reduces the formation of scars and keloids by controlling the mechanical environment at the wound site, preventing excessive matrix production and promoting healthier wound healing, with the ability to adapt to various wound sizes and skin types.
Implementation Method 1
straining skin on opposite sides of the wound to off load stresses at the wound site

AI summary
A skin frame or other skin straining device strains skin on each side of a wound where a wound has been closed to off load stresses at the wound site. A dressing may be applied to the strained skin. The dressing may be integral with one or more elements of the skin straining device.
