Sealing System for Membrane Rods with Jaw Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall insulation systems face challenges in maintaining airtightness and allowing for technical space between the membrane and the facing, which complicates the installation of cables and pipes, and requires piercing the membrane, potentially damaging it.
Innovation Solution
A sealing system with a first jaw adapted to engage on a ribbed rod section and a second jaw that locks in contact with the membrane, providing sealing at two levels to restore airtightness without piercing the membrane, and allowing for technical space for cables and pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the membrane is positioned on the inside of the lining frame, then the membrane is not pierced by spacer accessories during installation, but fixing the facing to the lining framework still pierces the membrane with fixing elements
Solution Approach 1:
The system divides the sealing function into two distinct components: the membrane provides the primary airtight barrier, while the sealing jaw with sealing element provides the secondary seal at penetration points. This segmentation allows each component to specialize in its function, with the membrane maintaining overall airtightness and the sealing jaw addressing localized piercings without compromising the membrane's integrity.
Solution Approach 2:
The sealing jaw acts as an intermediary component between the fixing elements and the membrane. Instead of fixing elements directly piercing the membrane, they first engage the sealing jaw, which then contacts and seals against the membrane. This intermediary protects the membrane from direct damage while still allowing secure attachment.
2Adaptability or versatility
If the membrane is positioned in front of the lining framework, then technical space is available for cables and pipes, but the membrane is damaged or distended by cables or fixing accessories
Solution Approach 1:
The sealing jaw serves as a protective intermediary between cables/pipes and the membrane. Cables and fixing accessories engage the sealing jaw rather than directly contacting the membrane, allowing technical space to be utilized while preventing damage or distention of the membrane through the jaw's protective function.
Solution Approach 2:
The sealing element functions as a flexible thin film that can deform to accommodate cables and pipes passing through or near the membrane area. This flexibility allows the sealing system to adapt to various cable configurations while maintaining the membrane's integrity and airtightness.
3Reliability
If cables are arranged behind the membrane, then the membrane is protected from damage, but access for maintenance or upgrading wiring installation requires removing or opening the membrane
Solution Approach 1:
The sealing jaw creates an accessible intermediate space between itself and the membrane where cables can be installed and maintained. This intermediate zone allows wiring work to be performed without compromising the membrane's protective position, while the removable or accessible nature of the sealing jaw provides easy access for maintenance activities.
Solution Approach 2:
The system segments the wall structure into three functional zones: the membrane providing the protective barrier, the intermediate space between the sealing jaw and membrane for cable installation and maintenance, and the sealing jaw itself as the accessible interface. This segmentation enables both membrane protection and easy maintenance access simultaneously.
4Reliability
If the edge of the engagement opening of the first jaw is adapted to match the shape of the rod section, then sealing with the rod is achieved, but the jaw must be precisely manufactured to conform to the rod profile
Solution Approach 1:
The sealing element uses material property changes (elastic deformation) rather than precise geometric matching to achieve sealing. The sealing jaw's engagement opening can have standard dimensions, and the sealing effect is achieved through the elastic deformation of the sealing element material when compressed against the rod, accommodating profile variations without requiring high manufacturing precision.
Solution Approach 2:
The sealing jaw combines a rigid structural component (the jaw body with engagement opening) with a compliant sealing material (the sealing element). This composite structure allows the rigid part to provide structural support and positioning, while the compliant material adapts to the rod profile through deformation, reducing the need for precise manufacturing of the engagement opening.
