Magnetic Ceiling Locator for Recessed Light Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During building construction, locating and accessing objects like recessed light fixtures mounted behind drywall or ceiling materials is challenging due to the concealment by sheet materials, requiring precise exposure without damaging the surrounding structure.
Innovation Solution
A locating device with a magnetically coupled assembly that includes a first assembly attachable to the light fixture's socket and a second assembly on the outer surface, utilizing opposite polarity magnets for alignment and a tubular member with splined surfaces to adjust length, allowing for accurate positioning and exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If sheet material is placed over structural members to conceal bodies, then the aesthetic appearance and structural integrity are improved, but the ability to locate and access the bodies deteriorates
Solution Approach 1:
The patent introduces magnetic assemblies as intermediary components that bridge the gap between the concealed body and the sheet material surface. The first magnetic assembly attaches to the body while the second assembly attaches to the sheet material, with their magnetic interaction providing tactile feedback that indicates the body's location without requiring direct visual detection through the sheet material.
2Device complexity
If the locating device uses fixed length assemblies, then the device structure is simplified, but the ability to accommodate various fixture sizes and depths deteriorates
Solution Approach 1:
The patent implements adjustability mechanisms in both magnetic assemblies that allow the length and position of components to be dynamically changed. The first assembly has adjustable length to reach different body depths, and the second assembly has adjustable positioning features to accommodate various fixture sizes and sheet material thicknesses, transforming a static device into an adaptable tool.
3Measurement precision
If the magnet strength is increased to improve alignment accuracy, then the alignment precision is improved, but the risk of damaging the sheet material or body deteriorates
Solution Approach 1:
The patent employs multiple magnets distributed across the assemblies rather than relying on a single high-strength magnet. This distributed magnetic field provides sufficient alignment precision through cumulative magnetic force while reducing the risk of concentrated stress or damage to the sheet material or body at any single point.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise location and exposure of recessed light fixtures by magnetically aligning the device, facilitating accurate cutting or drilling through the ceiling material while accommodating various fixture sizes and shapes.
Implementation Method 1
The second assembly has a magnet having an opposite polarity of the magnet of the first assembly

AI summary
A locating device for locating the centerpoint of a body such as a recessed light fixture behind a ceiling. The device includes an extendable first member connectable in the center of the body and a second member positionable on the outer surface of the ceiling. A magnet positioned in the first member cooperates with a magnet positioned in the second member to maintain the second member in an aligned position with the center of the body. The extendable first member accommodates various size bodies so that the magnet positioned in the first member extends to the ceiling for attraction to the magnet positioned in the second member.
