Solution Overview

Problem

Traditional bandages require repeated application and removal for wound examination and treatment, which is time-consuming and inconvenient for both caregivers and patients, especially for needy wounds that require multiple attentions during healing.

Innovation Solution

A multicomponent bandaging system with a base and a lid that allows repeated access to the wound without fully removing the bandage, using adhesive technology and hinging mechanisms to ensure easy opening and closing without disrupting skin adhesion, and featuring rocker-lock assemblies for secure closure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional bandages are used for wound care, then the wound can be covered and protected, but the bandage must be repeatedly removed and reapplied for wound examination and treatment, which is time-consuming and inconvenient

Engineering Contradiction:

Improveease of wound accessVSAvoidtime for bandage application and removal

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The bandaging system is divided into two functional segments: a base layer that remains adhered to the skin and provides continuous protection, and a removable lid that can be opened for wound access. This segmentation allows the protective function to persist while enabling easy wound examination and treatment without complete bandage removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lid is designed with dynamic characteristics, allowing it to be easily opened and closed multiple times while the base remains fixed. This dynamic design enables repeated wound access without requiring removal of the entire bandaging system, thus reducing time loss and improving operational ease.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the adhesive base is removed for wound access, then the wound can be examined and treated, but the adhesive must be reapplied which causes skin irritation and discomfort

Engineering Contradiction:

Improveease of wound accessVSAvoidskin irritation from adhesive

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

By separating the adhesive base from the removable lid, the system allows wound access without removing the adhesive component. The base remains adhered to the skin providing continuous protection, while only the non-adhesive lid is removed for wound care, thereby minimizing skin irritation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The removable lid acts as an intermediary that provides wound access without requiring removal of the adhesive base. This intermediary component enables wound examination and treatment while the adhesive remains in place, reducing direct contact between adhesive and skin that would cause irritation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If multiple bandages are used for one wound, then the wound can receive adequate care, but it increases the complexity of wound management and waste

Engineering Contradiction:

Improvequality of wound careVSAvoidnumber of bandages to manage

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The reusable base with multiple lids provides multi-functionality, serving as a single continuous bandaging system that can accommodate multiple wound care episodes. The base remains in place while different lids can be applied or the same lid reused, eliminating the need to manage multiple complete bandages and reducing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system allows for discarding only the removable lid after use while recovering and reusing the adhesive base. This selective discarding and recovery approach reduces the number of complete bandages needed, simplifying wound management and reducing waste compared to using multiple disposable bandages.

Inventive Principle:

Principle #34Discarding and recovering

AI summary

The base of this bandaging system is attached to the skin around a wound by adhesive and supports the edges of the lid, which covers the wound and can easily be removed and replaced or re-used many times to facilitate examining or treating the wound while the base remains in place. The bandaging system has multiple embodiments to accommodate various situations. An embodiment with generally planar components is very simple but may cause vertical pressure on the skin near the wound when the lid is removed or attached. Such pressure is avoided by alternative embodiments in which the components have non-planar parts. Some embodiments have a hinge on an edge of the lid which allows the wound to be uncovered without detaching the lid. The components which latch lids to bases contribute to making the systems easy, quick, convenient, and comfortable to use.
