Wall Insert with Sealing Sleeve for Waterproof Fastening in Wet Rooms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening solutions for damp or wet rooms, such as those in showers and bathtubs, fail to provide adequate strength and waterproofing, leading to moisture absorption and potential mold growth in building materials like gypsum panels and lightweight concrete, resulting in structural damage and instability.
Innovation Solution
A wall insert system featuring a body with a flange and sealing sleeve, which can be factory-fitted or site-installed, providing a secure and waterproof fastening solution by integrating into the composite seal of the room, using materials like cement adhesive or resin that are insensitive to moisture, and incorporating adjustable brackets and interchangeable elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If plasterboard or drywall panels are used in damp rooms, then installation ease is improved, but moisture resistance deteriorates leading to material saturation and strength loss
Solution Approach 1:
The wall insert divides the wall into dry and wet zones by creating a recess that houses waterproofing and sealing components, allowing the plasterboard to remain intact while protecting against moisture intrusion at specific locations
Solution Approach 2:
The wall insert acts as an intermediary element between the plasterboard and the wet environment, incorporating waterproofing membranes and sealing sleeves that prevent direct contact between moisture and the plasterboard material
2Strength
If dowel holes or cracks are present in plasterboard, then fastening capability is improved, but waterproofing deteriorates allowing moisture absorption and mold growth
Solution Approach 1:
The wall insert is installed before final waterproofing to preemptively seal potential moisture entry paths at dowel holes and cracks, preventing moisture ingress before it can cause damage
Solution Approach 2:
The sealing sleeve and waterproofing membrane serve as intermediary barriers that protect the plasterboard and surrounding areas from moisture while allowing fasteners to pass through the insert body
3Productivity
If lightweight wall materials like aerated concrete are used, then construction speed is improved, but structural strength deteriorates when waterproofing is damaged
Solution Approach 1:
The wall insert is pre-installed in the recess before final waterproofing and tiling, ensuring that lightweight materials maintain their load-bearing capacity by preventing moisture-induced strength degradation
Solution Approach 2:
The wall insert changes the local material parameters by introducing moisture-resistant components in critical areas, allowing lightweight materials to be used overall while maintaining strength where needed
4Device complexity
If traditional fastening methods are used in damp rooms, then simplicity is improved, but long-term reliability deteriorates due to moisture absorption and material degradation
Solution Approach 1:
The fastening system is segmented into the insert body embedded in the wall and the flange/bracket portion visible on the surface, with the insert providing secure anchoring in moisture-resistant materials while the bracket supports the fixture
Solution Approach 2:
The insert body acts as an intermediary between the wall structure and the bracket, providing threaded fasteners embedded in moisture-resistant material that maintain their holding power over time
