Replaceable Adhesive Bra Liner for Wrinkle-Free Skin Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive bras face challenges in smooth adhesion due to the high deformation of elastic and colloid materials, leading to wrinkles and reduced adhesion, and they are difficult to clean, which can harbor bacteria and affect health.
Innovation Solution
An adhesive-replaceable adhesive bra design with a molded cup, adhesive body, and limiting body, where the limiting body shapes and limits the molded cup or adhesive body, ensuring smooth adhesion and preventing wrinkles, and allows for separate packaging to prevent bacterial growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the adhesive layer is manually brushed or hot melted onto the adhesive bra, then the adhesive layer can be transferred to the adhesive bra, but the high deformation of elastic and colloid materials causes wrinkles and prevents complete adhesion to the skin
Solution Approach 1:
The adhesive layer is pre-transferred to a release liner in a controlled environment before use. This preliminary action allows the adhesive to be applied uniformly on a stable substrate (the release liner) where it can maintain its integrity, rather than being applied directly to the deformable adhesive bra material. The pre-transferred adhesive layer is then positioned and adhered to the adhesive bra in a single smooth operation, preventing wrinkles and ensuring complete contact.
2Ease of operation
If the adhesive bra is stored with the release liner inadequately adhered or missing, then storage is simpler, but impurities such as dust adhere to the adhesive layer, making it difficult to clean and reducing adhesion
Solution Approach 1:
The release liner serves as an intermediary protective barrier between the adhesive layer and the external environment during storage and handling. By keeping the release liner properly adhered to the adhesive layer, dust and impurities are prevented from contaminating the adhesive surface. The release liner can be easily removed at the point of use, allowing the clean adhesive layer to be applied to the skin without compromising adhesion performance.
3Duration of action of stationary object
If the adhesive bra is used multiple times, then reusability is improved, but the adhesive layer harbors bacteria, which has adverse effects on human health
Solution Approach 1:
The adhesive layer is separated from the adhesive bra structure by being transferred on a release liner. This extraction allows the adhesive layer to be removed and disposed of after a single use, while the adhesive bra itself can be cleaned and reused. The disposable adhesive layer prevents bacterial accumulation, as it is discarded after one use, while the reusable adhesive bra maintains its structural integrity and can be sanitized for subsequent uses.
4Ease of operation
If the adhesive layer is adhered to the skin with wrinkles due to material deformation, then application is simpler, but adhesion is reduced and comfort is poor
Solution Approach 1:
The adhesive layer is pre-applied to the release liner in a controlled manufacturing process, ensuring it is free of wrinkles and defects before reaching the user. This preliminary preparation eliminates the need for the user to manually smooth out wrinkles during application. When the release liner is removed and the adhesive layer is transferred to the adhesive bra and then to the skin, the pre-smoothed adhesive layer maintains its wrinkle-free condition, ensuring complete contact and comfort.
