Self-Adherent Compression Wrap for Consistent Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compression wraps fail to maintain consistent pressure, tend to slip or stretch out of shape, are difficult to remove and reapply, and are not washable or reusable, limiting their effectiveness in post-operative recovery and comfort.
Innovation Solution
Self-adherent compression wraps made from elongated strips of foamed plastic with a high percentage of plasticizer, allowing them to adhere to themselves and surfaces without a separate adhesive, which can be easily applied, removed, washed, and reapplied, conforming to body contours and providing adjustable pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bandages are used for compression wrapping, then the material provides initial compression, but the bandage tends to expand, slip and stretch out of shape, failing to maintain steady compression
Solution Approach 1:
The patent applies parameter changes by incorporating a high percentage of plasticizer (at least 40% by weight) into the foam material composition. This chemical parameter change transforms the material properties, enabling the foam to become self-adherent while maintaining compression stability and preventing the bandage from expanding or stretching out of shape during use.
Solution Approach 2:
The patent uses composite materials by creating a foam material that integrates multiple functions within a single substance. The foam combines structural support, adhesion (through incorporated plasticizer), and compression capabilities, eliminating the need for separate adhesive layers or components while maintaining shape retention and compression stability.
2Ease of operation
If self-adherent bandages with adhesive impregnation are used, then the wrapping sticks to itself, but the material is difficult to remove, reapply, and wash
Solution Approach 1:
The patent applies parameter changes by fundamentally altering how adhesion is achieved. Instead of using surface-applied adhesives that create strong bonds difficult to remove, the plasticizer is incorporated throughout the foam material matrix, creating a reversible adhesive effect that allows easy removal, washing, and reapplication while maintaining self-adherent properties during use.
3Stress or pressure
If pre-fabricated compression garments are used, then the garment provides compression, but it is either overly restrictive, uncomfortable, or unable to provide sufficient compression, and is difficult to fit properly
Solution Approach 1:
The patent applies segmentation by providing compression in the form of multiple separate bandage strips rather than a single pre-fabricated garment. This allows the compression to be applied in sections, easily adjusted to fit different body contours and sizes, and modified to provide appropriate compression levels without the restrictiveness of pre-fabricated garments.
Solution Approach 2:
The patent applies dynamics by making the compression system adjustable and adaptable. The bandage strips can be wrapped with varying tension, repositioned, removed, and reapplied as needed, allowing the compression force to be dynamically adjusted to match the patient's specific needs and body changes during recovery, unlike fixed pre-fabricated garments.
