Foldable Sealing Profile for Leak-Proof Corner Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing tapes used in sanitary installations, such as shower trays and bathtubs, face challenges in achieving optimal tightness in corner areas, requiring complex adjustments and often leading to leaks due to their limited adaptability and coverage of only two surfaces.
Innovation Solution
A foldable sealing tape design with multiple strips and a foldable area that can be adjusted to fit various installation scenarios, allowing seamless coverage of at least three surfaces without the need for on-site adaptation, featuring adhesive surfaces and materials that can be flexible or rigid, with folds that enhance foldability and tear-off edges for easy material management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional sealing tape is used with elastic material, then the sealing tape can conform to the installation object, but it straightens out due to elasticity from the corner edge, compromising sealing tightness
Solution Approach 1:
The sealing tape is divided into multiple strips (first strip, second strip, third strip, fourth strip) that can be independently positioned and adhered to different surfaces. This segmentation allows each strip to maintain its position without elastic recovery, while collectively covering the corner area and ensuring reliable sealing.
Solution Approach 2:
The sealing tape extends into a third dimension by having strips that can be adhered to vertical surfaces (connecting walls) in addition to horizontal surfaces (floor). This multi-surface coverage in different dimensions prevents the elastic straightening problem by distributing the sealing function across multiple planes.
2Ease of operation
If sealing tape is cut with a knife for adjustment, then adaptation to corner edges is improved, but leakage problems are introduced
Solution Approach 1:
The sealing tape is pre-configured with multiple strips and adhesive surfaces designed to accommodate various corner configurations without requiring on-site cutting or adjustment. The strips can be positioned and adhered in different arrangements to fit the corner edge, eliminating the need for knife adjustment and preserving sealing integrity.
3Device complexity
If sealing tape covers only two surfaces, then the structure remains simple, but seamless sealing of a third surface requires cutting and creates leakage risks
Solution Approach 1:
The sealing tape is designed with multiple strips that can be adhered to different combinations of surfaces (floor and connecting walls), making it universally applicable to various installation situations. The same sealing tape structure can seal two surfaces or three surfaces depending on the configuration, eliminating the need for cutting and ensuring continuous sealing.
4Adaptability or versatility
If foldable area is added to sealing tape, then adaptability to different installation situations is improved, but device complexity increases
Solution Approach 1:
The sealing tape incorporates a foldable area that allows dynamic adjustment of the strip configurations. The foldable area enables the strips to be folded along a folding edge to accommodate different corner configurations and installation situations, providing adaptability while maintaining a relatively simple overall structure.

AI summary
The sealing profile (100) has left lower strips (3) that are connected with an adjacent left upper strip (10). The right bottom strips (6) are connected to an adjacent right upper strips (13). The folding portion (500) is placed between the left upper strips and the right upper strip at different folding positions. An independent claim is included for method for mounting sealing profile.
