Septum Insertion via Suction Mandrel and Tapering Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inserting septums into carrier elements are complex, time-consuming, and costly, as they require separate steps for insertion and gluing, making them unsuitable for fully automatic processes.
Innovation Solution
A method using a suction mandrel to attach and elastically compress the septum, allowing it to be pushed through a tapering setting channel and securely clamped into the carrier element, eliminating the need for subsequent gluing and mechanical flanging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the septum is inserted using separate insertion and gluing steps as in prior art, then the connection between septum and carrier element is mechanically stable, but the process becomes complex and time-consuming
Solution Approach 1:
The patent combines the insertion and fixation steps into a single operation by using a setting bush with a tapering setting channel that elastically compresses the septum to create a self-locking connection, eliminating the need for separate gluing steps and reducing process complexity while maintaining mechanical stability
Solution Approach 2:
The setting bush acts as an intermediary tool that temporarily holds the septum during insertion and applies controlled elastic compression through its tapering channel, enabling automatic fixation without additional bonding agents or separate operations
2Reliability
If separate insertion and gluing steps are used as in prior art, then the septum can be securely fixed, but the manufacturing time and cost increase
Solution Approach 1:
The patent merges multiple operations (insertion, compression, and fixation) into a single automated process step using the setting bush, thereby reducing manufacturing time and increasing productivity while ensuring secure fixation through elastic compression
Solution Approach 2:
The septum is designed to be self-fixing through elastic compression in the tapering setting channel, where the compressed septum naturally locks into the carrier element opening without requiring external bonding agents or additional fixation steps, enabling fully automated high-speed production
3Reliability
If the septum is elastically compressed in the setting channel, then the septum is firmly clamped in the setting opening, but the septum experiences material stress during insertion
Solution Approach 1:
The setting channel is designed with a gradual taper that progressively compresses the septum, cushioning the material stress by distributing the compression force over the insertion process rather than applying sudden high stress, while still achieving firm clamping in the final position

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method enables a cost-effective, time-saving, and fully automatic process for inserting septums into carrier elements, ensuring a mechanically stable connection without additional aids or steps, reducing material stress and preventing protrusion.
Implementation Method 1
the septum is initially attached by means of a suction mandrel (40) to its end face by suction
Implementation Method 2
it is pushed into the setting opening (2) of the carrier element (3), the septum (1) being elastically compressed at least in the lateral direction while the septum (1) is being pushed through the setting channel (52)

AI summary
The invention relates to a method for inserting at least one septum (1) into a setting opening (2) of a support element (3), wherein the septum (1) is attached to a suction mandrel (40) in a first step by means of suction;In a second step, the septum (1) is positioned over an opening (51) of a setting sleeve (5) arranged vertically (V) between the suction mandrel (40) and the support element (3), and after the setting sleeve (5) is flush with the support element (3), the septum (1) is pushed completely through a setting channel (52) of the setting sleeve (5), which tapers in cross-section from the opening (51) towards the support element (3), by means of the suction mandrel (40) and inserted into the setting opening (2) of the support element (3), whereby during the pushing of the septum (1) through the setting channel (52), the septum (1) is elastically compressed at least in the lateral direction in order to clamp the septum (1) in the setting opening (2).
