Method and assembly set for a sealed connection of a shower or bath tub
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing methods for bathtubs and shower trays in room corners often result in wrinkles due to non-flat and non-angled distances between the bathtub and room walls, compromising the sealing effect.
Innovation Solution
A method involving a tub sealing tape with a V-shaped incision and a bridging strip that is glued over the cut, allowing for a continuous, wrinkle-free application by adhering to angled walls, and an installation kit with a non-stretchable tub sealing strip and stretchable bridging strip to ensure a uniformly sealed connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a two-layer structure with transition element overlapping sealing strips is used in the corner area, then the sealing tape can be attached to non-flat and non-angled walls, but wrinkles form and sealing effect is reduced
Solution Approach 1:
The sealing tape is divided into two functional layers: a non-stretchable sealing strip that provides the primary seal, and a stretchable bridging strip that adapts to wall irregularities. This segmentation allows each layer to perform its specific function without interfering with the other, preventing wrinkles while maintaining adaptability.
Solution Approach 2:
Different regions of the sealing system have different properties: the sealing strip is non-stretchable to maintain seal integrity, while the bridging strip is stretchable to accommodate wall variations. This local differentiation of material properties resolves the contradiction between adaptability and sealing precision.
2Manufacturing precision
If the sealing tape is made non-stretchable to maintain seal integrity, then sealing precision is improved, but it cannot adapt to varying distances between bathtub and walls
Solution Approach 1:
The sealing system is segmented into a non-stretchable sealing strip for maintaining seal integrity and a stretchable bridging strip for adapting to wall variations. This allows the system to simultaneously achieve both sealing precision and adaptability through functional division.
Solution Approach 2:
The stretchable bridging strip acts as an intermediary element between the non-stretchable sealing strip and the irregular walls. It mediates the geometric mismatches and distance variations, allowing the sealing strip to maintain its integrity while the system adapts to wall variations.
3Ease of operation
If the transition element overlaps the sealing strips, then attachment to angled walls is enabled, but a two-layer structure causes wrinkles
Solution Approach 1:
The sealing system is segmented into a sealing strip layer and a bridging strip layer, where each layer has a specific function. The bridging strip is positioned to bridge wall gaps without creating overlapping layers on the sealing surface, enabling easy attachment while preventing wrinkles.
Solution Approach 2:
The bridging strip operates in a different functional dimension than the sealing strip. While the sealing strip provides the seal, the bridging strip handles the geometric adaptation in a separate layer, allowing attachment to angled walls without compromising seal quality.
