Spring-Closed Line Feedthrough for Reliable Gas Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing line feedthroughs may not securely close the passage through the hose body, potentially allowing gas to pass through, due to user errors or inadequate closure mechanisms.
Innovation Solution
A line feedthrough design that includes a cladding tube, a fastening element, and a flexible hose body with a spring device that presses the hose body toward a closed position, ensuring the passage is completely closed regardless of the number and size of lines guided through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual closure mechanism is used for the hose body, then the device complexity is reduced, but the reliability of closing the passage is compromised due to user errors
Solution Approach 1:
The spring device automatically closes the hose body passage without requiring user intervention. The spring mechanism self-activates to return the hose body to its closed position after being opened, eliminating reliance on user memory or attention and preventing user errors while maintaining relatively simple device architecture
Solution Approach 2:
The spring device is pre-loaded to store elastic energy that automatically actuates the hose body closure. This preliminary energy storage ensures that the closing action is reliably initiated without requiring real-time user input, thereby improving closure reliability while keeping the mechanism simple
2Reliability
If the hose body is made fully rigid to ensure secure closure, then the sealing effectiveness is improved, but the ease of operation for guiding lines through is reduced
Solution Approach 1:
The hose body is designed as a flexible element that can dynamically change its configuration between an open state (for easy line insertion) and a closed state (for reliable sealing). This dynamic flexibility allows the hose body to adapt to different operational requirements, maintaining both ease of operation and sealing effectiveness
Solution Approach 2:
The hose body utilizes flexible material properties to achieve secure closure while remaining easy to operate. The flexibility of the hose body allows it to be manually opened for line guidance and then automatically returned to a sealed closed position by the spring mechanism, combining operational ease with reliable sealing
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
The solution ensures that the hose body securely closes the passage, preventing gas from passing through, and reduces the risk of user errors by maintaining the closed position through the use of a spring device.
Implementation Method 1
a spring device is provided which acts on the fastening element, which can be displaced in the axial direction relative to the cladding tube, with a force which presses the hose body toward its closed position

AI summary
A line feedthrough for guiding at least one line through a component, contains a cladding tube, a fastening element, and at least one sealing element which is in the form of a flexible hose body and arranged within the cladding tube. The hose body is connected, in a first axial end region, to the fastening element. It is possible to displace said hose body between a closed position, in which the hose body at least partially closes a passage through the hose body, and an open position, in which a passage through the hose body is at least partially unblocked. A spring device is provided that acts on the fastening element, which can be displaced in the longitudinal direction (L) relative to the cladding tube, with a force that presses the hose body toward a closed position.
