Sealing Sleeve and Mounting Section for Concealed Pipe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for ensuring a closed water flow through a wall cladding from a concealed pipe to the room side are prone to leaks due to inadequate sealing, which can lead to undetected moisture damage, and require complex coordination between plumbers and tilers for precise installation and sealing.
Innovation Solution
A method involving a sealing sleeve that surrounds the connecting piece of the flush-mounted pipe, with a building plug inserted within, providing a continuous watertight seal from the concealed pipe to the room side, allowing for leak detection and remediation, and maintaining the seal throughout the construction process without requiring significant adjustments or specialized sealing collars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a building plug is used to seal the connecting piece and a sealing sleeve is pulled over it, then the connecting piece can be sealed watertight, but high friction between the building plug and sealing sleeve can damage the sealing sleeve and impair its sealing capability
Solution Approach 1:
The patent introduces a mounting section as an intermediary element between the building plug and the sealing sleeve. This mounting section features an outer profile that contacts the building plug and an inner profile that contacts the sealing sleeve, acting as a mediator that reduces direct friction and prevents damage to the sealing sleeve while maintaining the sealing function.
Solution Approach 2:
The sealing assembly is segmented into distinct functional components: the building plug for blocking, the sealing sleeve for sealing, and the mounting section for facilitating assembly. This segmentation allows each component to perform its specific function optimally without interfering with others, particularly protecting the sealing sleeve from damage during installation.
2Reliability
If the sealing sleeve is expanded to the size of the building plug over a long period, then it can seal the building plug, but it often does not contract sufficiently after the building plug is removed and is therefore only insufficiently in contact with the fitting connection piece
Solution Approach 1:
The mounting section serves as a permanent intermediary structure that maintains the sealing relationship after the building plug is removed. The sealing sleeve seals against the mounting section rather than relying on contraction from the building plug, ensuring continuous sealing contact throughout the service life of the installation.
3Reliability
If the connecting piece is sealed with a building plug during shell construction, then the water pipe can be tested for leaks, but the construction process requires complex coordination between plumbers, tilers, and fine installation craftsmen
Solution Approach 1:
The mounting section is designed as a universal component that serves multiple functions: it facilitates initial sealing during shell construction, maintains sealing during wall cladding installation, and enables final fitting connection during fine installation. This multi-functionality reduces the need for specialized components for each construction phase and simplifies coordination between different craftsmen.
4Ease of operation
If a passage is provided in the wall cladding for the water pipe, then water flow to the room side is enabled, but there is a risk that water from the room side can get through to the flush-mounted side and cause permanent damage to the structure
Solution Approach 1:
The sealing sleeve acts as a flexible sealing barrier that conforms to the mounting section and blocking body, creating a moisture-tight seal around the passage through the wall cladding. This flexible sealing membrane prevents water from penetrating through the passage to the flush-mounted side while allowing the water pipe to pass through.
