Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective devices for dressings and injured skin areas are inefficient due to unpredictable dimensions, shapes, and locations, leading to unnecessary purchases of incorrect sizes and discomfort from non-adaptable designs, and they fail to provide a sealed barrier against contamination.
Innovation Solution
A protective kit comprising a thin, flexible, waterproof base sheet that can be cut to size and a waterproof, non-allergenic adhesive in a compressible tube, allowing for customizable coverage and secure sealing with a continuous adhesive bead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-sized protective devices are used, then protection coverage is provided, but the devices are either too small or too large leading to waste and discomfort
Solution Approach 1:
The protective device is divided into two separate components: a reusable waterproof base sheet and disposable adhesive beads. This segmentation allows the base sheet to be used repeatedly with different dressings while the adhesive beads are consumed as needed, reducing waste of the main protective structure.
Solution Approach 2:
The base sheet is designed to be dynamically resizable through cutting and folding, allowing it to adapt to various dressing dimensions. The sheet can be cut to custom sizes and folded to accommodate different body contours, providing versatility without requiring multiple pre-sized devices.
2Adaptability or versatility
If pre-shaped protective devices are used, then protection coverage is provided, but the devices do not adapt to irregular body shapes causing discomfort
Solution Approach 1:
The base sheet transitions from a flat stored state to a customized three-dimensional configuration during use. It can be folded, cut, and shaped to match irregular body contours and movement requirements, providing both adaptability and comfort.
Solution Approach 2:
The device uses a flexible thin film base sheet that can conform to various body shapes and movements. The material's flexibility allows it to adapt to irregular contours while maintaining comfort during limb movement and body activity.
3Reliability
If adhesive tape with perforations is used, then the sheet can be fixed on the skin, but the seal between skin and sheet is not guaranteed
Solution Approach 1:
The adhesive function is extracted from the base sheet and implemented as separate dispensable adhesive beads. This allows the adhesive to be applied only where needed around the dressing perimeter, creating an effective seal without requiring adhesive coverage across the entire sheet surface.
Solution Approach 2:
Adhesive is applied locally only at the peripheral edges around the dressing rather than uniformly across the entire base sheet. This localized adhesive application creates effective sealing at the critical interface between skin and protective sheet while reducing adhesive complexity and material usage.
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 kit provides effective, customizable protection against soiling and contamination with impure elements, ensuring a secure and comfortable fit for varied body conformations, while being economical and easy to use.
Implementation Method 1
a waterproof and non-allergenic adhesive, preferably provided with a spout for dispensing this adhesive in the form of a bead, said adhesive having properties enabling it to adhere both to the skin and the protective sheet
Implementation Method 2
The deposition of a continuous bead of adhesive between the skin and the protective sheet not only allows effective fixing of the latter, but also ensures the function of a perfectly sealed barrier
Implementation Method 3
at least one overall sheet or non-dedicated, thin, flexible and waterproof base sheet
