Pre-wall Installation Shell with Flange for Watertight Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sanitary spaces, existing methods for concealing technical installations behind breeze block walls often compromise watertightness when recesses or shelves are added, and electrical appliances can leak moisture due to improper fitting.
Innovation Solution
A shell with a flange is integrated into the pre-wall, allowing a watertight layer to cover the panels and overlap with the shell's flange, ensuring watertightness regardless of the nested element, and can be used for recesses, shelves, or electrical appliances, with adjustable stops and flexible edges for sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a recessed part such as an alcove or a built-in cabinet is arranged in the pre-wall, then the functionality and aesthetics of the space are improved, but the watertight layer has to be interrupted and additional sealing components are required
Solution Approach 1:
The nesting element is placed inside the shell, which itself is integrated into the pre-wall. This nested structure allows the recessed part to be accommodated while the shell maintains the watertight barrier, eliminating the need to interrupt the watertight layer.
Solution Approach 2:
The shell acts as an intermediary component between the pre-wall and the nesting element. It provides a watertight interface that connects to the pre-wall's watertight layer, allowing the nesting element to be installed without compromising the overall watertightness.
2Adaptability or versatility
If a shelf is arranged on the pre-wall, then the storage functionality is improved, but screws must be screwed into the pre-wall affecting the watertightness
Solution Approach 1:
The shelf is arranged as a nesting element within the shell structure. The shell provides mounting surfaces and structural support, allowing the shelf to be fixed without penetrating the pre-wall's watertight layer, thus maintaining watertightness while providing storage functionality.
3Adaptability or versatility
If electrical appliances such as a fan are arranged in the ceiling or wall, then ventilation functionality is improved, but improper fitting causes leakage and moisture penetration
Solution Approach 1:
The shell serves as an intermediary housing for the electrical appliance (e.g., fan). It provides integrated sealing interfaces and connection points that ensure proper fitting and prevent leakage, while the appliance itself remains protected within the watertight shell structure.
4Adaptability or versatility
If an alcove or built-in cabinet is arranged in the pre-wall, then the aesthetic appearance is improved, but the alcove must be covered with a sealing layer that adversely affects its appearance
Solution Approach 1:
The sealing function and the aesthetic covering are merged into a single integrated shell structure. The shell itself is designed to be aesthetically pleasing while inherently providing the sealing function, eliminating the need for separate sealing layers that would compromise appearance.
