Wall Drain Gutter With Adjustable Gap For Shower Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall drains for showers are complex, inflexible, and require special construction or recesses in the masonry, occupying floor space and being difficult to install, while also not allowing full use of the floor area due to their design.
Innovation Solution
A wall drain channel using pre-wall technology with a vertically adjustable gap between the wall and floor, allowing for flexible installation without altering the existing masonry, featuring a wall unit and floor unit with adjustable screws and a web for optimal water flow and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wall drains are installed, then water drainage function is achieved, but the installation becomes complex and inflexible requiring special construction
Solution Approach 1:
The drainage system is divided into separate modular components: a floor unit with drainage channel, a wall unit with vertical flange, and a wall covering strip. These segments can be installed independently and assembled together, eliminating the need for complex integrated construction and allowing flexible installation sequences.
Solution Approach 2:
The wall covering strip is designed with adjustable positioning through multiple hole rows at predetermined intervals, allowing dynamic adjustment of the vertical gap height between wall and floor coverings. This enables flexible adaptation to different floor thicknesses and installation conditions while maintaining proper water drainage function.
2Reliability
If conventional wall drains with fixed gap are used, then water passage is provided, but the construction becomes inflexible requiring recesses in masonry
Solution Approach 1:
The system transforms the fixed gap design into a dynamic, adjustable gap through the wall covering strip with multiple positioning holes. The gap height can be varied by selecting different hole positions, allowing adaptation to different floor coverings thicknesses and installation conditions without requiring fixed recesses in the masonry structure.
Solution Approach 2:
The vertical gap dimension is changed from a fixed parameter to a variable parameter that can be adjusted within a range. The wall covering strip provides discrete adjustment positions at predetermined intervals, enabling the gap height to be optimized for different installation scenarios while maintaining proper water drainage function.
3Area of stationary object
If floor area is reduced for drainage channel, then installation space is available, but full floor coverage is lost
Solution Approach 1:
The drainage system transitions from a horizontal floor-mounted channel to a vertical wall-integrated channel. The drainage opening is positioned vertically at the wall-floor junction, allowing water to drain through the vertical gap and into the drainage channel without occupying horizontal floor space. This dimensional change enables full floor coverage while maintaining effective water drainage capability.
4Ease of operation
If pre-wall technology is used, then installation simplicity is improved, but adjustable gap height capability is needed
Solution Approach 1:
The wall covering strip incorporates multiple rows of holes at predetermined intervals along its length, providing discrete adjustment positions for the vertical gap height. This dynamic positioning capability allows the installer to select the appropriate gap height for different floor covering thicknesses while maintaining the simplicity of pre-wall technology installation methods.
Solution Approach 2:
The wall covering strip serves multiple functions: it provides the adjustable positioning mechanism for gap height control, acts as a support element for the wall covering, and defines the lower boundary of the vertical gap. This multi-functionality maintains installation simplicity while enabling gap height adaptability across different application scenarios.

AI summary
The invention relates to a wall drain channel for a shower, which can be installed using pre-wall technology, comprising a drain channel (20), a wall unit (30) arranged above the drain channel (20) for attaching a wall covering, in particular tiles, and a floor unit (40) arranged next to the drain channel (20) for laying a floor covering, in particular tiles, wherein the dimensions of the drain channel (20), the wall unit (30) and the floor unit (40) are selected such that a vertical gap (50) is formed in the corner edge between the wall covering and the floor covering as a water drain, wherein the gap (50) is fluidically connected to the drain channel (20) and wherein a wall covering strip (32) is provided which can be attached to a vertical flange section (31) of the wall unit (30) at a variable height and has a stop edge (33) arranged at the bottom for attaching a wall covering.so that the height of the vertical gap (50) can be adjusted before the wall and floor coverings are installed. The wall drainage channel according to the invention is characterized in that the wall covering strip (32) has at least two rows of bores (34), each with a predetermined grid of distances from the stop edge (33), and that at least one longitudinally extending groove (36) is provided in the vertical flange section (31) of the wall unit (30), into which one or more screws (35) that can be inserted into the bores (34) can be screwed. The invention solves the technical problem of creating a wall drainage channel of the type mentioned above that is simpler and more flexible to install than conventional wall drainage channels, and whose gap height can be adjusted variably and conveniently.
