Elastomeric Bandage Pad Alignment via Single Connection Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bandage devices fail to maintain an absorbent pad aligned with a wound when the bandage is stretched, restricting movement and not providing secure coverage.
Innovation Solution
An elastomeric bandage with an adhesive layer and a pad attached at a single connection point, where the pad remains motionless and aligned with the wound even when the bandage is stretched, using a fluid absorbent material and a protective sheet to prevent adhesion issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pad is attached to the bandage at multiple points or distributed attachment, then the pad is securely fixed to the bandage, but the pad moves and becomes misaligned with the wound when the bandage is stretched
Solution Approach 1:
The attachment system is segmented into a single connection point rather than distributed attachment. The pad is attached to the bandage at one specific location, allowing the rest of the pad to remain free and maintain alignment with the wound during stretching, while still providing secure fixation through the single attachment point
Solution Approach 2:
A connection point structure serves as an intermediary between the pad and the bandage. This intermediary element allows the pad to be attached securely while accommodating the stretching motion of the bandage, preventing direct transmission of stretching forces to the pad tissue interface
2Adaptability or versatility
If the bandage is made highly elastic to allow movement, then the user can move freely, but the pad becomes misaligned with the wound during stretching
Solution Approach 1:
The system is segmented into the elastic bandage portion and the pad portion with a defined connection point. This segmentation allows the bandage to stretch independently while the pad maintains its positioning through the single connection point attachment, resolving the conflict between bandage elasticity and pad alignment
Solution Approach 2:
The connection point has specialized local properties that differ from the rest of the bandage and pad structures. This local quality at the connection point allows it to accommodate stretching while maintaining pad alignment, providing different functional characteristics at different locations in the system
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 allows for secure, non-restrictive wound coverage with the pad remaining positioned over the wound, facilitating absorption of bodily fluids without limiting user movement.
Implementation Method 1
An adhesive layer is applied to the elastomeric bandage to adhere to the user's body when the elastomeric bandage is wrapped around the user's body
Implementation Method 2
The pad is comprised of a fluid absorbent material to absorb bodily fluids from the wound

AI summary
An elastomeric bandage device includes an elastomeric bandage that can be wrapped around a user's body such that the elastomeric bandage extends over a wound in the user's body. An adhesive layer is applied to the elastomeric bandage to adhere to the user's body when the elastomeric bandage is wrapped around the user's body. A pad is attached to the elastomeric bandage at a connection point such that the pad is inhibited from being stretched when the elastomeric bandage is stretched. In this way the pad remains positioned over the wound when the elastomeric bandage is wrapped over the wound. The pad is comprised of a fluid absorbent material to absorb bodily fluids from the wound.
