Reinforced Applicator With Stiffened Support for Flat Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reinforced applicators made of non-woven fabrics are inconvenient to operate, prone to deformation, and difficult to adhere flatly on the skin surface, leading to inaccurate placement and reduced adhesive effectiveness.
Innovation Solution
A reinforced applicator design with a supporting portion having a higher Young's modulus than the adhesion portion, featuring a first and second supporting member, allows for easy one-handed operation and accurate application by reducing deformation and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the reinforced applicator is made of non-woven fabric with softer texture, then it is comfortable to wear, but it is inconvenient to operate and easy to deform when picked up
Solution Approach 1:
The reinforced applicator is divided into two functional segments: a softer adhesion portion for comfort and a stiffer supporting portion for structural integrity. The supporting portion includes a first supporting member (ring-shaped) and a second supporting member (protruding from the first), which are integrated with but distinct from the adhesion portion. This segmentation allows each part to perform its specialized function without compromising the other.
Solution Approach 2:
Different regions of the reinforced applicator are assigned different material properties: the adhesion portion uses softer non-woven fabric for comfort against the skin, while the supporting portion uses stiffer material with higher Young's modulus for deformation resistance. This local differentiation of material quality enables the applicator to simultaneously achieve comfort and operational convenience.
2Reliability
If the reinforced applicator is made of softer non-woven fabric, then it is comfortable, but it is difficult to adhere flatly on the skin surface
Solution Approach 1:
The supporting portion with higher Young's modulus is strategically positioned at the periphery and extends toward the center, providing localized rigid support that prevents the softer adhesion portion from wrinkling during application. This local quality differentiation ensures the adhesion surface remains flat while maintaining comfort.
Solution Approach 2:
The reinforced applicator combines two materials with different mechanical properties: softer non-woven fabric for the adhesion portion and stiffer material for the supporting portion. This composite structure allows the softer material to conform to the skin comfortably while the stiffer material maintains flatness and prevents deformation during application.
3Measurement precision
If the reinforced applicator is placed on the periphery of the applicator in sleeving manner, then it secures the applicator, but it is hard to localize accurately and deflection is easy to happen during one-handed operation
Solution Approach 1:
The supporting portion is segmented into a ring-shaped first supporting member that provides circumferential support for accurate localization, and a second supporting member that protrudes from the first to serve as a convenient grip point for one-handed operation. This segmentation enables both precise positioning and easy handling.
Solution Approach 2:
The second supporting member acts as an intermediary element that facilitates one-handed operation by providing a protruding grip point. This intermediary structure allows the user to easily pick up and position the applicator without directly handling the soft adhesion portion, thereby improving localization accuracy.
4Ease of operation
If the reinforced applicator uses softer material, then it is comfortable, but wrinkles are easily produced when stuck on the skin surface
Solution Approach 1:
The supporting portion with higher Young's modulus is positioned at the periphery and extends toward the center, providing localized rigid support that prevents the softer adhesion portion from wrinkling during application. This local quality differentiation ensures the adhesion surface remains flat while maintaining comfort.
Solution Approach 2:
The reinforced applicator combines softer non-woven fabric for the adhesion portion with stiffer material for the supporting portion. This composite structure allows the softer material to remain comfortable against the skin while the stiffer material prevents wrinkle formation by maintaining structural integrity during application.

AI summary
The present disclosure describes a reinforced applicator (1), including an adhesion portion (11), a supporting portion (12), and an adhesive layer (13). The adhesion portion (11) has an upper surface and a lower surface which are opposite to each other. The Young's modulus of the supporting portion (12) is greater than the Young's modulus of the adhesion portion (11) and supports the adhesion portion (11). The supporting portion (12) has a first supporting member (121) provided on the adhesion portion (11), and a second supporting member (124) formed by extending from the first supporting member (121) along the direction away from the upper surface, the adhesive layer (13) is provided on the lower surface. According to the present disclosure, it is able to provide a reinforced applicator (1) which can be conveniently picked up and accurately reinforce an applicator in the case of one-handed operation.
