Lining unit for the shape-replacement of a room

Solution Overview

Problem

Existing lining units for wet areas in buildings often require complex assembly and may not provide adequate moisture protection, especially in areas where moisture occurs on both floor and side walls, such as showers and bathrooms.

Innovation Solution

A pre-fabricated lining unit with a one-piece floor part and side parts of varying heights, where the side parts can be connected to form seamless transitions and cover different heights, using a thermoplastic film that can be easily cut to accommodate pipes and fittings, and featuring a triple-layer side seam for enhanced stability and moisture protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a lining unit is assembled on site from multiple individual elements, then adaptability to different room configurations is improved, but assembly complexity and time increase

Engineering Contradiction:

Improveadaptability to room configurationsVSAvoidassembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lining unit is divided into a floor part and multiple side parts that can be assembled on-site. The side parts can be connected in different configurations (e.g., 2, 3, or 4 side parts) to adapt to various room widths and door opening positions, while maintaining a standardized base floor part design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The side parts are pre-formed with standardized connection elements (adhesive strips or welding flaps) that enable quick assembly. The pre-formed corner formations and standardized heights reduce on-site preparation work and simplify the assembly process.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If a lining unit is assembled on site from multiple individual elements, then adaptability to different room configurations is improved, but assembly time increases

Engineering Contradiction:

Improveadaptability to room configurationsVSAvoidassembly time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The lining unit is divided into a floor part and multiple side parts that can be assembled on-site. The side parts can be connected in different configurations (e.g., 2, 3, or 4 side parts) to adapt to various room widths and door opening positions, while maintaining a standardized base floor part design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The side parts are pre-formed with standardized connection elements (adhesive strips or welding flaps) that enable quick assembly. The pre-formed corner formations and standardized heights reduce on-site preparation work and simplify the assembly process.

Inventive Principle:

Principle #10Preliminary action

3Ease of manufacture

If standard-height side parts are used, then manufacturing and assembly are simplified, but moisture protection in areas with high moisture exposure is inadequate

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidmoisture protection

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The lining unit provides different side part heights (first height and second height) to match different moisture exposure levels in various wall areas. Higher side parts are used in areas with high moisture exposure (e.g., where water directly hits walls), while lower side parts are sufficient in drier areas, optimizing both protection and material usage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The invention adds the height dimension as a variable parameter for side parts. Instead of using uniform height throughout, the system incorporates multiple height levels (first height for high-moisture areas, second height for low-moisture areas) to provide appropriate moisture protection where needed while maintaining manufacturing efficiency through standardized production of different height variants.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

The invention relates to a lining unit (1) with a base part (4) and side parts (5, 6, 7, 8) extending from the base part (4), wherein the base part (4) and the side parts (5, 6, 7, 8) are formed from a waterproof film. To further develop such a lining unit (1), it is proposed that the base part (4) is formed in one piece with at least one side part (5, 6, 7, 8), wherein the lining unit (1) is prefabricated for lining a room (2) such as a wet room, wherein the dimensions of the base part (4) correspond to the area of the floor of the room (2), and wherein the dimensions of each side part (5, 6, 7, 8) correspond to the area of a wall or an opening, such as a door, of the room (2), wherein the side parts (5, 6, 7, 8) completely surround the base part (4) and the base part (4) and the side parts (5, 6, 7, 8)8) each have an inner and an outer surface, wherein the inner surfaces are further formed with an adhesion structure (35) for the attachment of tiles (32), wherein the side parts (5, 6, 7, 8) form a right or obtuse angle with each other in a cross-section parallel to the floor with respect to their inner or outer surfaces and have different heights (a, b), namely, in any case, a first and a second side part (5, 6, 7, 8) have a first height (a) and a third and optionally further side parts (5, 6, 7, 8), including in particular an opening side part (5, 6, 7, 8), have a second height (b), wherein the first height (a) corresponds to a multiple of the second height (b).
