Split Grommet Assembly for Stranded Element Feedthrough Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grommets require installation together with stranded elements, making replacement or maintenance complex, time-consuming, and costly, especially when forgotten during installation.
Innovation Solution
A split-design grommet comprising two separate elements that can be installed independently of the stranded element, allowing for easy adaptation to different openings and designs, with the ability to be installed before or after the stranded element, and featuring collars and cavities for protection and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a grommet is designed as a single integrated piece, then it provides complete protection for the stranded element, but it requires uninstallation of the stranded element for replacement or maintenance
Solution Approach 1:
The grommet is divided into two separate grommet elements that can be installed and removed independently. Each element can be fitted separately to the opening, allowing maintenance without uninstalling the stranded element while maintaining complete protection when both elements are in place
2Strength
If a grommet is designed as a single integrated piece, then it provides structural edge protection, but it must be installed together with the stranded element making installation complex
Solution Approach 1:
The grommet is segmented into two separate elements that can be installed independently of the stranded element. This allows the grommet to be fitted to the opening first, providing edge protection before the stranded element is installed, simplifying the overall installation process
3Stability of the object's composition
If a grommet is designed as a single integrated piece, then it maintains structural integrity, but it cannot be easily adapted to different opening dimensions
Solution Approach 1:
The grommet is divided into two separate elements that can be selected and combined in different configurations to match various opening dimensions. Each element can be independently sized and shaped, providing adaptability to different openings while maintaining structural integrity when assembled together
Solution Approach 2:
The two-element grommet system can be configured in multiple ways to accommodate different opening sizes and shapes. The elements can be interchanged or repositioned to fit various geometries, making the grommet system universally applicable to different openings

AI summary
A grommet for feeding a stranded element through an opening includes a first grommet element having an elongated first body with a first collar radially extended relative to the first body. The grommet includes a second grommet element having an elongated second body with a second collar radially extended relative to the second body. The first grommet element and the second grommet element are formed separately from each other. A feedthrough includes the grommet, and a method includes feeding a stranded element through an opening.
