Wedge-Shaped Magnet Mount for Oblique Shelf Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices attached to metal shelves using magnets often result in light being emitted vertically downwards, leading to inefficient product illumination as some light shines beyond the shelves, causing customer dazzling and inadequate product lighting.
Innovation Solution
A wedge-shaped magnet is used for magnetic attachment of the lighting device to the shelf, allowing the lamp to be positioned asymmetrically, ensuring light is emitted obliquely downwards, thereby directing all light towards the products and preventing unnecessary illumination of areas in front of the shelves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a magnet of uniform thickness is used to attach the lamp to the shelf, then the lamp is attached vertically downwards with symmetrical positioning, but the light is emitted vertically downwards causing some light to shine beyond the shelves and leading to customer dazzling and inadequate product lighting
Solution Approach 1:
The patent applies asymmetry by using a wedge-shaped magnet with non-uniform thickness instead of a magnet of uniform thickness. This asymmetric design causes the lamp to be attached at an oblique angle rather than vertically, directing the light beam onto the products on the shelf below while preventing light from shining beyond the shelf edges, thus resolving the contradiction between ease of manufacture and lighting efficiency
2Device complexity
If the lamp is positioned to emit light vertically downwards, then the attachment structure is simple and symmetrical, but part of the light is wasted by shining beyond the shelves and does not illuminate the products
Solution Approach 1:
The wedge-shaped magnet introduces asymmetry into the attachment structure, which tilts the lamp at an oblique angle. This asymmetric positioning redirects the light beam onto the products, ensuring that all emitted light energy is utilized effectively for product illumination rather than being wasted by shining beyond the shelf edges
Solution Approach 2:
The magnet has non-uniform thickness with a thicker end and a thinner end, creating local quality variation. This design concentrates the light direction onto a specific target area (the products on the shelf below) while preventing light dispersion into unwanted areas, thereby reducing energy loss
3Illumination intensity
If a larger lamp is used to ensure sufficient product illumination, then adequate lighting is achieved, but energy consumption increases and the need for weaker luminaires is lost
Solution Approach 1:
By using the asymmetric wedge-shaped magnet to direct light precisely onto the products, the system achieves high illumination intensity on the target area with a smaller, lower-power lamp. The oblique angle ensures concentrated light delivery, eliminating the need for larger, higher-consumption luminaires that would be required with vertical downward lighting
