Detent Mounting Assembly for Electrical Fixture Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical fixture mounting systems require complex and often labor-intensive processes for both electrical and mechanical connection, particularly for larger fixtures, which can be challenging for single installers to manage effectively.
Innovation Solution
A mounting assembly comprising an upper unit with a detent mechanism and upper contacts, and a lower unit with a corresponding detent mechanism and lower contacts, allowing for a male-female coupling that facilitates self-alignment and secure electrical and mechanical connection over a range of insertion depths, with features like a collet ring and locking slide for adjustable retention and easy disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mounting methods are used for larger electrical fixtures, then the fixture can be securely mounted, but the installation process becomes labor-intensive and requires multiple installers
Solution Approach 1:
The mounting assembly is divided into separate upper and lower units that can be independently handled and then easily connected. The upper unit attaches to the electrical box while the lower unit attaches to the fixture, allowing a single installer to manage each component separately before joining them together through the detent mechanism.
Solution Approach 2:
The mounting assembly acts as an intermediary device between the electrical box and the fixture. It provides a standardized interface with male-female coupling that simplifies the connection process, allowing the installer to work with manageable components rather than directly handling the entire heavy fixture assembly.
2Productivity
If traditional mounting methods are used, then electrical connections can be established, but the process becomes time-consuming and difficult to align properly
Solution Approach 1:
The upper and lower units are pre-formed with complementary male-female coupling features and keyed electrical contacts. This preliminary preparation of alignment features ensures that when the installer connects the units, they self-align quickly without requiring time-consuming manual adjustment or precise positioning.
Solution Approach 2:
The mounting assembly uses asymmetric male-female coupling features and keyed contacts that guide proper alignment during insertion. The asymmetric design ensures that only the correct orientation fits together, eliminating the need for trial-and-error alignment and reducing installation time.
3Reliability
If a secure mechanical connection is used to hold the fixture, then the fixture remains stable, but the disengagement process becomes difficult when maintenance is needed
Solution Approach 1:
The detent mechanism provides dynamic retention that is stable during normal operation but can be easily released when needed. The spring-loaded detent holds the upper and lower units firmly together through engagement of protrusions and recesses, ensuring stable connection. For disengagement, the release button allows the installer to override the detent and separate the units with minimal effort.
Solution Approach 2:
The mounting assembly is designed to be temporarily discarded (disassembled) for maintenance and then recovered (reassembled) when needed. The quick-release detent mechanism facilitates this cycle by allowing easy separation for maintenance access while maintaining secure connection during operation, enabling the installer to efficiently discard and recover the assembly as needed.

AI summary
A mounting assembly for an electrical fixture has an upper unit and a lower unit. The upper unit includes a first portion of a detent mechanism and an upper contact for connection to a power source. The lower unit is configured for connection to an electrical fixture and includes a second portion of a detent mechanism and a lower contact for connection to the electrical fixture. When the lower unit engages the upper unit, the first portion and the second portion of the detent mechanism cooperate to releasably retain the upper unit and lower unit together and the upper contact and lower contact touch to create an electric pathway between the power source and the electrical fixture.
