Shelf Label Lighting Layout to Eliminate Retail Shelf Shadows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic shelf illumination systems mounted on ceilings suffer from shadow effects, lack of light beam variability, and high installation and maintenance costs, requiring expensive equipment and skilled operation.
Innovation Solution
An electronic shelf label system with a display screen and independently controllable illumination device attached to the shelf rail, allowing for precise and flexible lighting adjustments, reduced infrastructure needs, and low-power operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If illumination devices are mounted on the ceiling, then the entire shelf area can be illuminated, but shadow effects are caused by the shelf structure or customers
Solution Approach 1:
The illumination system is segmented into multiple independent illumination devices, each integrated into individual electronic shelf labels positioned at different locations along the shelf. This distributed segmentation eliminates shadow effects by providing light from multiple angles and positions, replacing the single ceiling-mounted source.
Solution Approach 2:
The electronic shelf label structure serves as an intermediary carrier that integrates both the display function and illumination function. The illumination device is embedded within the shelf label housing, using the shelf label itself as the mounting intermediary, which positions the light source optimally near the products without requiring ceiling installation.
2Adaptability or versatility
If expensive illumination devices with high variability are used, then lighting flexibility and focus control are improved, but installation and maintenance costs increase significantly
Solution Approach 1:
The electronic shelf label is designed as a universal platform that combines multiple functions: product information display, pricing information, and illumination. The same housing and power infrastructure serve both the display screen and the illumination device, eliminating the need for separate theatrical lighting equipment and reducing overall system cost.
Solution Approach 2:
The illumination device is integrated into the electronic shelf label structure, using the label's own housing, power supply, and mounting mechanism. This self-service integration eliminates the need for separate installation infrastructure and simplifies maintenance, as the illumination component can be serviced together with the electronic shelf label itself.
3Illumination intensity
If ceiling-mounted illumination devices are used, then broad area coverage is achieved, but the light beam lacks variability in diameter, orientation, and shape
Solution Approach 1:
Each illumination device integrated into the electronic shelf label is positioned locally near specific products or product groups on the shelf. This local positioning allows each light source to be optimized for its specific illumination task, providing variable orientation and focused coverage for different product arrangements, rather than using a single ceiling-mounted source for the entire area.
Solution Approach 2:
The illumination system enables dynamic control of individual illumination devices through independent controllable features. Each illumination device can be adjusted in intensity, timing, and activation based on specific needs such as highlighting particular products, creating dynamic lighting scenarios that adapt to different retail situations.
4Manufacturing precision
If expensive control devices are installed to achieve precise lighting control, then lighting precision is improved, but operation complexity and user skill requirements increase
Solution Approach 1:
The control functionality is merged into the electronic shelf label's existing control architecture. The same controller that manages display content and pricing information also controls the illumination device, eliminating the need for separate theatrical lighting control equipment and simplifying the user interface to what retail staff are already familiar with.
Solution Approach 2:
The illumination device is designed to be self-regulating and automatically controllable through the electronic shelf label's existing communication protocols. The system can automatically adjust illumination based on pre-programmed schedules, product information, or sensor inputs, reducing the need for manual intervention and specialized operator skills.
