Nasal Dilator Segmented Release Liner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nasal dilators require a dedicated member, such as a pad or net, to prevent adhesion of the adhesive substance layer to the top region of the nose bridge, which can lead to skin peeling and damage upon removal.
Innovation Solution
A nasal dilator design featuring a flexible strip with an adhesive substance layer and a release liner divided into three pieces, where the first and third pieces are removed to adhere the adhesive substance layer to the nose bridge, and the second piece remains to prevent adhesion to the top region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a dedicated member (pad or net) is added to prevent adhesion to the top region of the nose bridge, then skin protection is improved, but device complexity increases
Solution Approach 1:
The release liner is divided into three separate pieces: a first piece covering one longitudinal end region, a second piece covering the longitudinal middle region, and a third piece covering the other longitudinal end region. This segmentation allows the middle piece to remain and protect the top region of the nose bridge from adhesion, while the end pieces are removed to allow proper adhesion to the nose bridge sides, thereby preventing skin damage without adding dedicated protective members
Solution Approach 2:
The second piece of the release liner acts as an intermediary protective layer between the adhesive substance layer and the top region of the nose bridge. This middle piece remains adhering to the adhesive substance layer during use and prevents direct contact between the adhesive and the sensitive top region of the nose bridge, thereby preventing skin peeling and damage
2Object-affected harmful factors
If the release liner is divided into three pieces with the middle piece remaining, then skin protection is improved, but manufacturing complexity increases
Solution Approach 1:
The release liner is divided into three separate pieces that can be manufactured independently or as a single piece with pre-defined separation zones. This segmentation allows the middle piece to remain and protect the top region of the nose bridge from adhesion, while the end pieces are removed to allow proper adhesion to the nose bridge sides
Solution Approach 2:
The first and third pieces of the release liner are designed to be discarded (removed) during application, while the second piece is recovered and remains in place to provide ongoing protection to the top region of the nose bridge. This selective discarding and recovery approach simplifies the manufacturing process compared to adding dedicated protective members
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
This design effectively prevents the adhesive substance layer from adhering to the top region of the nose bridge, thereby avoiding skin peeling and damage during removal, without the need for a dedicated member.
Implementation Method 1
an adhesive substance layer formed on entire of one surface of the flexible strip

AI summary
This invention relates to a nasal dilator. An object of this invention is to provide a nasal dilator wherein adhesive substance layer is prevented from adhering to a top region of a nose bridge, and which does not need a dedicated member for preventing the adhesion of the substance layer to the top region of the nose bridge. The object is achieved by a nasal dilator comprising a flexible strip, an adhesive substance layer formed on one surface of the flexible strip and a release liner covering the adhesive substance layer, wherein the adhesive substance layer is formed on entire surface of said one surface of the flexible strip, the release liner is divided into three pieces, a first of which covers one longitudinal end region of the adhesive substance layer, a second of which covers longitudinal middle region of the adhesive substance layer and a third of which covers another longitudinal end region of the adhesive substance layer.
