Solution Overview

Problem

Existing adhesive bandages fail to adequately protect wounds from external contaminants, particularly around joints, due to buckling and loosening of the adhesive, and often provide insufficient gauze coverage.

Innovation Solution

A wound/bandage protection system utilizing a super-stretchable elastic non-woven material with a strip and fasteners, designed to securely wrap around limbs, preventing buckling and maximizing gauze coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a thin strip of adhesive is used around the gauze pad to adhere to the skin, then the bandage can be applied to cover the wound, but the adhesive buckles or comes loose particularly around joints, failing to keep the wound properly sealed

Engineering Contradiction:
Improvewound sealing reliabilityVSAvoidadhesive stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent uses a flexible membrane layer that extends beyond the gauze pad to provide a stable base for adhesive application. This membrane acts as a flexible shell that maintains its integrity around joints, preventing the adhesive from buckling or loosening while still allowing the bandage to conform to body contours.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent extends the adhesive layer in a different dimension by providing a membrane that protrudes beyond the gauze pad edges. This dimensional extension creates an overlapping adhesive region that wraps around the limb, distributing stress and preventing buckling at the adhesive-gauze interface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If the gauze is extended to the edge of the adhesive to maximize wound coverage, then more gauze is available to cover the wound, but the adhesive area is reduced and cannot provide adequate sealing

Engineering Contradiction:
Improvegauze coverage areaVSAvoidwound sealing reliability
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent segments the bandage structure into distinct functional layers: a gauze pad layer for wound coverage and a membrane layer for adhesive application. This segmentation allows each layer to be optimized independently - the gauze can be sized for maximum wound coverage while the membrane provides sufficient adhesive area for reliable sealing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flexible membrane layer serves as an intermediary structure that separates the gauze pad from the adhesive function. It extends beyond the gauze edges to provide adequate adhesive surface area without reducing the gauze coverage, maintaining both wound coverage and sealing reliability.

Inventive Principle:
Principle #30Flexible shells and thin films

3Adaptability or versatility

If the adhesive bandage is designed to conform to bending limbs, then it can be applied to joints, but the gauze and adhesive buckle and loosen due to the bending motion

Engineering Contradiction:
Improvejoint adaptabilityVSAvoidbandage structure stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The flexible membrane layer acts as a stable platform that maintains its structural integrity during bending motions. Its flexibility allows the bandage to adapt to joint movements, while its extended design prevents buckling of the gauze and adhesive layers by distributing mechanical stress across a larger area.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent uses dimensional extension of the membrane layer to create overlapping regions that wrap around the limb. This dimensional approach allows the bandage to accommodate bending motions by distributing stress across multiple layers and areas, preventing buckling while maintaining joint adaptability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
