Brush Port Assembly With Split Bezel for Existing Cable Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brush port assemblies for electronic equipment enclosures require complex installations and often necessitate disassembly or removal of existing cables, making it difficult to install them in openings with already present cables or wiring.
Innovation Solution
A brush port assembly with a single-piece bezel and brush component, featuring a discontinuous perimeter, hooks, and deflectable tabs, allowing toolless installation by engaging edges and applying force to secure the assembly without disassembling existing cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional multi-piece brush port assemblies are used, then installation flexibility around existing cables is improved, but device complexity and installation time increase
Solution Approach 1:
The patent combines multiple separate components (bezel, brush component, mounting features) into a single integrated brush port assembly. The bezel and brush component are pre-assembled as one unit with mounting features built-in, eliminating the need for separate installation steps and reducing the number of individual parts while maintaining installation flexibility.
Solution Approach 2:
The bezel incorporates a discontinuous perimeter with gaps that allow the assembly to be installed around existing cables. This segmentation of the bezel perimeter enables adaptability to different cable configurations without requiring complete disassembly of the enclosure or removal of existing cables.
2Ease of operation
If toolless installation features are added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The assembly incorporates self-installing features including deflectable tabs that automatically engage with mounting surfaces and hooks that self-align during installation. These features enable the assembly to install itself without requiring external tools or complex adjustment procedures, making installation simple while keeping the device structure relatively straightforward.
3Ease of operation
If a single-piece bezel with discontinuous perimeter is used, then ease of installation around cables is improved, but structural strength may be reduced
Solution Approach 1:
The discontinuous perimeter bezel incorporates localized reinforcement at critical stress points and uses strategically positioned mounting features to compensate for the gaps. The reinforcement ensures that the reduced perimeter structure maintains sufficient structural strength for its intended application while preserving the installation advantage of the discontinuous design.

AI summary
A brush port assembly includes a bezel frame and a brush component. The bezel frame is comprised of an elongate body having first and second ends, a top surface, and an underside. The elongate body is formed as a generally enclosed shape that frames an opening, whereby the first and second ends are arranged in an end-to-end relationship with a gap therebetween. The brush component has a spine member from which a plurality of bristles extend. The spine member is secured to the underside of the elongate body such that the bristles substantially entirely cover the opening. The bezel frame is installable, without the aid of tools, along an exposed edge of a brush port opening in a surface of an electronic equipment enclosure. Additionally, the bezel frame is installable around a cable that passes through the brush port opening by maneuvering the cable through the gap.
