Lining Unit for Shape-Corresponding Lining of a Room
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lining units for wet areas in buildings are complex to assemble and may not provide adequate moisture protection, especially in areas where water can hit the side surfaces.
Innovation Solution
A pre-fabricated lining unit with a one-piece bottom part and side parts, where the side parts have varying heights to accommodate different moisture exposure areas, and feature an adherence structure for tile attachment and a three-layered side seam for enhanced stability and moisture protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lining units are made up on site of multiple individual elements, then adaptability to different assembly spaces is improved, but device complexity and ease of assembly deteriorate due to the need to connect numerous parts
Solution Approach 1:
The patent combines multiple individual elements (bottom part and side parts) into a pre-assembled one-piece lining unit. The side parts are already connected to the bottom part in the correct configuration before delivery, eliminating the need for on-site assembly of multiple separate components while maintaining adaptability through pre-configured design.
Solution Approach 2:
The lining unit is pre-assembled in the factory with side parts already connected to the bottom part in the proper configuration. This preliminary assembly action is performed before delivery to the construction site, reducing on-site assembly complexity while ensuring correct installation geometry.
2Adaptability or versatility
If lining units are made up on site of multiple individual elements, then adaptability to different assembly spaces is improved, but ease of assembly deteriorates due to time-consuming connection processes

3Ease of manufacture
If standard height side parts are used, then manufacturing simplicity is improved, but moisture protection deteriorates in areas with varying moisture exposure heights
Solution Approach 1:
The patent applies different heights to different side parts based on their specific functional requirements. Side parts exposed to higher moisture levels or splash zones are made taller, while side parts in drier areas can be shorter. This local differentiation of quality (height) ensures adequate moisture protection where needed while maintaining manufacturing efficiency.

AI summary
A lining unit has a bottom part and side parts standing upright starting at the bottom part, wherein the bottom part and the side parts are made of a water-tight film. The bottom part is formed in one piece with at least one side part, and the lining unit is formed in a pre-fabricated manner for lining a room, such as a wet room. The side parts completely border the bottom part and form a right or obtuse angle with one another in a cross section parallel to the floor and have different heights. At least a first and a second side part have a first height and a third and further side parts, including an opening side part, have a second height, with the first height corresponding to a multiple of the second height.
