Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of seals at the end of components and the sealing connection between components and lines passing through them is often complex and difficult, particularly for pipes and electrical lines in building structures.
Innovation Solution
A seal with a circumferential turn-over collar that inverts from an assembly position to a sealing position, allowing for a simplified assembly and reliable sealing without the need for additional clamping devices, utilizing an elastically deformable sealing ring and one-piece design for enhanced sealing efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional sealing methods are used, then sealing connection is achieved, but assembly becomes complex and difficult requiring additional clamping devices
Solution Approach 1:
The turn-over collar is designed to automatically seal against the component section when inverted, eliminating the need for additional clamping devices or complex assembly procedures. The collar's geometry and elastic sealing ring enable self-sealing functionality upon simple inversion movement.
Solution Approach 2:
The turn-over collar utilizes an inversion movement to transform from an open assembly position to a closed sealing position. By inverting the collar structure, the sealing surface is brought into contact with the component section, achieving sealing through this reverse motion rather than traditional compression or threading mechanisms.
2Reliability
If multiple sealing components are used, then sealing reliability improves, but installation complexity increases
Solution Approach 1:
The turn-over collar integrates multiple sealing functions into a single component. It combines the sealing ring, the sealing surface, and the mechanical constraint function into one integrated structure that performs multiple sealing tasks simultaneously, reducing the number of separate components needed.
Solution Approach 2:
The turn-over collar serves multiple functions: it provides sealing against the component section, maintains sealing pressure through its elastic deformation, and prevents line displacement. This multi-functional design achieves reliable sealing without requiring multiple specialized components.
3Adaptability or versatility
If elastic sealing rings are used, then sealing adaptability improves, but structural complexity increases
Solution Approach 1:
The elastic sealing ring utilizes material elasticity to adapt its dimensional parameters. When the turn-over collar is inverted and contacts the component section, the sealing ring deforms elastically to accommodate variations in line diameter and create a reliable seal across different sizes without requiring adjustable mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy handling and secure sealing of components and lines without tools, providing multiple sealing levels and accommodating varying line diameters, ensuring a robust and adaptable sealing solution.
Implementation Method 1
The turn-over collar has an elastically deformable sealing ring at its collar end for circumferential contact with the component section. During the transfer of the turn-over collar from the assembly position to the sealing position, the elastically deformable sealing ring on the turn-over collar is expanded so that, in the sealing position the sealing ring creates a circumferential sealing effect on the outside of the component section due to the material expansion and the resulting restoring forces acting in the sealing ring.
