Two-Part Cable Grommet Structure for Automated Sealed Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable grommets require manual intervention to thread cables through a through-opening, disrupting automated production and mounting processes, and are not easily mountable or reliable in operation.
Innovation Solution
A two-part cable grommet composed of identical carrier bodies, each with a funnel-shaped base body from a soft component and a clamping element from a hard component, allowing seamless connection without interrupting the manufacturing or mounting process, featuring a sealing element and cover portion for enhanced protection and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable grommets are formed integrally from a soft component with a through-opening for threading cables, then sealing effectiveness is improved, but manual intervention is required which disrupts automated production processes
Solution Approach 1:
The cable grommet is divided into two separate carrier bodies (first and second carrier bodies) that can be produced independently and then connected. This segmentation allows each carrier body to be manufactured using automated processes without requiring manual cable threading, while the combined structure maintains the sealing effectiveness of the integral design.
2Reliability
If cable grommets are formed integrally from a soft component, then sealing effectiveness is improved, but ease of manufacture and mounting is reduced
Solution Approach 1:
The integral grommet is segmented into two carrier bodies that can be manufactured separately using optimized processes for each component. The first carrier body can be produced with its sealing elements, and the second carrier body with its corresponding features, allowing for easier and more flexible manufacturing and mounting operations.
Solution Approach 2:
The two carrier bodies are designed to nest together, with the second carrier body fitting onto or into the first carrier body. This nesting arrangement simplifies the assembly process while maintaining the overall sealing structure, making the grommet easier to manufacture and mount compared to a single integral piece.
3Productivity
If a two-part cable grommet structure is used to enable automated mounting, then productivity is improved, but device complexity increases
Solution Approach 1:
The grommet is segmented into two functional carrier bodies that can be independently manufactured and then connected through automated processes. The first carrier body contains the sealing elements, while the second carrier body provides the connecting structure, allowing for automated assembly without significantly increasing overall device complexity.
Solution Approach 2:
The two carrier bodies are merged into a single functional unit that performs both sealing and mounting functions. The connection between the first and second carrier bodies integrates their individual functions into a cohesive structure that enables automated mounting while maintaining simplicity.

AI summary
According to the disclosure, a cable grommet consisting of two identical carrier bodies is provided. The carrier bodies each comprise an approximately funnel-shaped base body formed from a soft component, and a clamping element formed from a hard component, wherein the carrier bodies can be connected to one another by means of the clamping element along a connecting face in order to form the cable grommet.
