Cable Tray Mounting Insert Assembly for Quick Tray Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire tray attachment systems require the removal of mounting inserts from mounting studs before the wire tray can be detached from the substrate, which is inefficient and cumbersome.
Innovation Solution
A system comprising a wire tray with mounts and mounting inserts that utilize a snap-fit connection, allowing the wire tray to be removed from the substrate without first unscrewing the insert from the stud, by de-actuating the snap-fit connection between the insert and the mount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a threaded mounting insert is used to attach the wire tray to the substrate, then the wire tray can be securely mounted, but the removal process requires unscrewing the insert from the stud first, which is time-consuming and cumbersome
Solution Approach 1:
The mounting system is segmented into three distinct components: the wire tray body, the mounting insert, and the mounting stud. The insert can be independently removed from the stud while remaining retained in the wire tray, allowing the wire tray to be detached without unscrewing the insert. This segmentation enables the insert to serve as a reusable mounting interface that remains on the substrate while the wire tray is removed and reinstalled.
Solution Approach 2:
The mounting insert acts as an intermediary component between the wire tray and the substrate. It provides a threaded interface that engages with the mounting stud on the substrate, while also being retained in the wire tray through the snap-fit connection. This intermediary allows the wire tray to be mounted and dismounted without removing or unscrewing the insert, as the insert remains as a permanent interface on the substrate.
2Reliability
If the mounting insert is permanently threaded onto the stud, then secure mounting is achieved, but the wire tray cannot be removed without first removing the insert, which complicates the removal process
Solution Approach 1:
The system transitions from a static permanent mounting configuration to a dynamic reusable configuration. The mounting insert can be independently removed from the wire tray and reinstalled, allowing the wire tray to be dynamically mounted and dismounted multiple times. The snap-fit connection provides a reusable mechanical interface that maintains mounting security while enabling repeated installation and removal cycles without compromising the threaded engagement with the substrate.
3Ease of manufacture
If a simple push-on connection is used, then easy installation is achieved, but insufficient mounting security and reliability are obtained
Solution Approach 1:
The mounting system merges two different connection mechanisms: a snap-fit connection for easy installation and retention, and a threaded connection for secure mounting. The insert is retained in the wire tray through the snap-fit connection (providing ease of installation), while simultaneously providing a threaded interface with the mounting stud (providing mounting security). This combination allows the wire tray to be easily installed and securely mounted without requiring complex fastening procedures.

AI summary
This publication describes techniques and apparatuses for releasably attaching an object (e.g., a wire tray) to a substrate. Current apparatuses generally do not enable the removal of an attached wire tray from a substrate without first removing an insert from a mounting stud extending from the substrate. The disclosed techniques and apparatuses are configured to permit the removal of an attached wire tray from a substrate without first removing an insert from a mounting stud extending from the substrate.
