Magnetic LED Bar Kit Side Magnet Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lighting solutions face challenges in single-person installation on ladders due to the need for manual screw handling, which is complicated by the use of magnets that obstruct heat dissipation and increase the profile of the fixture, and often require additional aluminum structures for mounting, increasing costs.
Innovation Solution
A magnetic LED bar kit with toroidal magnets attached to the sides and ends of the LED strip, allowing for magnetic attachment to metal substrates and single-handed installation, while maintaining thermal contact through conductive paste and extruded metal frames with heat dissipation fins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnet is placed on the bottom of the LED bar to hold it in place during installation, then the installer's hands are freed for screw handling, but a gap is created between the LED bar and fixture body that prevents heat dissipation
Solution Approach 1:
The magnet is relocated from the bottom surface to the side surface of the LED bar, changing the spatial dimension of magnetic attachment. This allows the bottom surface to remain in full contact with the fixture body for heat dissipation while the side magnet provides holding force during installation.
Solution Approach 2:
The LED bar is divided into functional zones: the bottom surface is dedicated to thermal contact with the fixture body, while the side surface contains the magnet for installation assistance. This segmentation allows each surface to fulfill its primary function without interference.
2Ease of operation
If a magnet is placed on the bottom of the LED bar to enable magnetic attachment, then installation is simplified, but the profile height of the fixture increases
Solution Approach 1:
The magnet is positioned on the side surface of the LED bar rather than the bottom, utilizing the lateral dimension for magnetic attachment. This keeps the vertical profile low while still providing hands-free installation capability.
3Ease of operation
If a magnet is placed on the bottom of the LED bar for magnetic attachment, then installation is easier, but adjustment becomes difficult because not all fixture bodies are flat under the magnet
Solution Approach 1:
The magnet is relocated to the side surface where it can accommodate varying fixture body geometries. The side position allows the magnet to engage with different surface profiles while the LED bar maintains proper alignment through the retaining channel system.
4Adaptability or versatility
If aluminum structures are added to hold magnets and provide mounting holes, then mounting functionality is achieved, but cost increases
Solution Approach 1:
The magnet-holding function and mounting hole provision are merged into the existing LED bar structure. The retaining channels in the LED bar frame serve dual purposes: holding the magnet in position and providing mounting holes for screw attachment, eliminating the need for separate aluminum structures.
Solution Approach 2:
The LED bar frame is designed with multi-functionality: it provides structural support, heat dissipation pathways, magnet retention through side channels, and mounting capability through integrated holes. This universal design eliminates the need for additional specialized components.
