Multi-Web Holding Teeth for High-Force Toothed Disks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toothed disks for media lines lack a reliable holding force, as the holding teeth pendulate around the axis of rotation, resulting in insufficient holding force when a load is applied, and require excessive plugging force for feedthrough.
Innovation Solution
The toothed disk design features holding teeth connected to the mounting section by at least two connecting webs, which enhance mobility and elasticity, preventing pendulum movement and allowing for adjustable insertion forces, with a wrapping angle of at least 70% of the perimeter to increase holding force, and a limited number of holding teeth to reduce insertion force and prevent tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If holding teeth are connected to the mounting section by a single connecting web, then the structure is simpler, but the holding force is insufficient due to pendulum movement
Solution Approach 1:
The connection between the holding tooth and mounting section is segmented into multiple connecting webs instead of a single web. This segmentation prevents the holding tooth from pendulating around the rotation axis by distributing the connection points, thereby ensuring reliable holding force while maintaining structural simplicity.
2Strength
If the holding teeth have a large wrapping angle, then the holding force increases, but the insertion force also increases
Solution Approach 1:
The holding teeth are designed with different local qualities: the contact surface area is optimized to provide sufficient wrapping angle for holding force, while the connecting webs are designed with specific geometric parameters (width, distance from rotation axis) to reduce flexural resistance and insertion force. This local optimization allows the system to achieve both high holding force and low insertion force.
3Ease of operation
If the connecting webs are made more flexible, then the mobility of holding teeth increases, but the structural stability decreases
Solution Approach 1:
The connecting webs are designed with dynamic characteristics that allow them to be flexible during insertion (providing mobility and elasticity) while maintaining structural stability during operation. The geometric parameters of the connecting webs are optimized to provide the right balance between flexibility for ease of insertion and rigidity for stable holding under load.
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 design ensures a high holding force with reduced plugging force requirements and prevents tilting of holding teeth, providing a secure and efficient fastening mechanism for media lines of varying diameters.
Implementation Method 1
The flexural resistance of the connecting webs acts together with the mobility due to the punch-outs, so that the insertion forces for the media line can be readily adjusted. In addition, a pendulum movement of the holding teeth due to the connecting webs is essentially prevented.

AI summary
A toothed disk for fastening a feedthrough-plug-connected media line. The toothed disk includes a circular insertion opening that is defined at a periphery of the insertion opening by elastic holding teeth, separated from each other by respective slots. In the axial direction, the holding teeth extend at an angle to a longitudinal axis that is perpendicular the plane of the insertion opening. Each holding tooth is connected to an outer mounting section by at least one connecting web. Punch-outs are formed between the connecting webs. A mounting section is arranged on a peripheral circle around the insertion opening and lies in a plane parallel to the plane of the insertion opening. Each holding tooth is connected to the mounting section by at least two connecting webs. Also provided is a connection assembly for the feedthrough plug connection of a media line including the toothed disk.
