Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing methods for lead-ins through vapour barriers during building renovations are cumbersome and labor-intensive, particularly for existing pipes and wires, as traditional sealing tapes are time-consuming and difficult to achieve aesthetic and airtight fittings.
Innovation Solution
A self-vulcanizing renovation collar made of flexible sheet-like material with adhesive and a central opening, allowing easy installation on existing pipes and wires by overlapping and self-vulcanizing to form a watertight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sealing tapes are used to seal lead-ins through vapour barriers during renovations, then sealing can be achieved, but the process becomes time-demanding and labor-intensive
Solution Approach 1:
The sealing solution is divided into separate functional components: a pre-cut sheet-like material with adhesive on one side for attachment to the vapour barrier, and self-vulcanizing properties that enable the material to bond to itself when overlapped. This segmentation allows for faster installation while maintaining sealing effectiveness.
Solution Approach 2:
The sheet-like material is pre-cut with cuts from the central opening to the periphery before installation. This preliminary preparation enables the material to be easily wrapped around and overlapped on existing pipes and wires during renovation, significantly reducing installation time while ensuring proper sealing geometry.
2Reliability
If traditional sealing tapes are used to seal lead-ins through vapour barriers, then sealing can be achieved, but achieving aesthetic and airtight fittings becomes difficult
Solution Approach 1:
The material undergoes a parameter change through self-vulcanization, transforming from a non-crosslinked state to a crosslinked elastic state. This chemical transformation enables the material to form permanent, airtight bonds when overlapped, ensuring reliable sealing while simplifying the installation process compared to traditional tapes.
Solution Approach 2:
The sealing collar combines multiple material properties in one product: adhesive properties for attachment to the vapour barrier, self-vulcanizing capability for self-bonding, and flexible sheet-like structure for easy wrapping. This composite approach ensures both airtightness and ease of operation.
3Adaptability or versatility
If known sealing collars are used during renovations, then they work for new buildings, but they cannot be used for existing pipes and wires that cannot be peeled off and reinstalled
Solution Approach 1:
The sheet-like material is designed to be flexible and dynamic during installation, allowing it to be wrapped around existing pipes and wires of various shapes and sizes. The material's flexibility enables adaptation to existing infrastructure without requiring removal or reinstallation of pipes and wires, while the self-vulcanizing property provides the stability needed for permanent sealing.
Solution Approach 2:
The sealing collar is made as a flexible sheet-like material that can conform to the shape of existing pipes and wires. This flexible film structure allows the collar to be installed over existing infrastructure without rigid constraints, significantly improving adaptability while maintaining sealing effectiveness through the self-vulcanizing mechanism.
