Diffusion-Tight Sanitary Wall Elements for Moisture-Resistant Renovation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for renovating sanitary rooms do not effectively address the challenge of moisture ingress due to high humidity, which can lead to damage and reduce the sustainability of the renovation.
Innovation Solution
The introduction of a diffusion-tight layer between the decorative and carrier plates, with additional diffusion agents at functional points, ensures that the wall elements remain moisture-proof even at areas with installation lines or electrical connections, and the use of a diffusion-tight trough at the floor level prevents moisture from entering the sanitary room or floor sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functional points (connection points, control elements) are provided in the wall elements for water and electricity supply, then the usability and functionality of the sanitary room is improved, but the diffusion-tightness of the wall element is compromised at these locations
Solution Approach 1:
A diffusion-tight membrane is introduced as a thin film that selectively covers functional points in the wall element. This membrane allows water and electricity to pass through at the functional points while maintaining diffusion-tightness for moisture vapor in the surrounding areas, thus resolving the contradiction between functionality and moisture protection.
Solution Approach 2:
The wall element is designed with differentiated properties: areas with functional points have permeable characteristics to allow utility passage, while the surrounding areas maintain diffusion-tight properties. This local differentiation enables the wall element to simultaneously provide functionality and prevent moisture ingress in non-functional areas.
2Reliability
If the wall elements are made diffusion-tight to prevent moisture ingress, then the sustainability and durability of the renovation is improved, but the installation of installation lines and functional points becomes more complex
Solution Approach 1:
The diffusion-tight membrane is pre-integrated into the wall element during factory production, with functional points already positioned and the membrane configured to accommodate them. This preliminary preparation eliminates the need for complex on-site modifications to achieve both diffusion-tightness and functionality, simplifying the installation process.
Solution Approach 2:
The wall element combines multiple materials and layers including the carrier plate, decorative layer, and diffusion-tight membrane in a composite structure. This composite design integrates moisture protection and utility passage capabilities into a single unified component, reducing overall installation complexity while maintaining durability.
