Solution Overview
Problem
Retail environments face challenges with small-sized print on shelf tags, poor lighting conditions, and outdated information, making it difficult for consumers to read product information and for retailers to maintain operational efficiency.
Innovation Solution
An electronic shelf-tag system featuring a fascia-mounted LED array that displays product information in shared electronic shelf tags for multiple consecutive shelf slots, with proximity detection to display information only when customers are present, and the ability to automatically or manually group products for unified tagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If printed shelf tags are used to display product information, then the information can be provided in physical form, but the text becomes difficult to read due to small-sized print and poor lighting conditions
Solution Approach 1:
The patent replaces the mechanical/optical system of printed text with an electronic LED display system. The LED array dynamically generates illuminated text and graphics, eliminating the need for physical light reflection from printed surfaces. This substitution enables active light emission, ensuring high visibility and readability regardless of ambient lighting conditions.
Solution Approach 2:
The system changes the physical state of information display from static printed text to dynamic electronic text with adjustable parameters. The LED display can modify brightness, contrast, and illumination intensity based on ambient light detection, ensuring optimal readability across different lighting conditions while maintaining energy efficiency.
2Extent of automation
If traditional shelf tags are used, then the structure remains simple, but the information is not timely updated when products are sold out or replaced
Solution Approach 1:
The system implements a feedback mechanism where the LED display continuously receives real-time product data from the retail management system. When product inventory status changes or products are replaced, the system automatically detects these changes through data communication protocols and updates the display accordingly, ensuring information accuracy without manual intervention.
Solution Approach 2:
The electronic shelf tag system performs self-updating by automatically receiving, processing, and displaying new product information without requiring manual tag replacement. The system autonomously manages information lifecycle from data reception to display update, reducing labor time and ensuring timely information availability.
3Loss of information
If LED array horizontal resolution is limited for a shelf slot, then the device complexity remains low, but the product information cannot be fully displayed
Solution Approach 1:
The system employs dynamic display techniques where the LED array adjusts its content presentation based on available resolution. Text and graphics are dynamically scaled, wrapped, or prioritized to fit the display area while maintaining readability. The system can also dynamically switch between different information types (e.g., from detailed descriptions to key product attributes) based on space constraints.
Solution Approach 2:
When horizontal resolution is insufficient, the system utilizes the vertical dimension for additional information display. The LED array can arrange product information in multi-line formats, use vertical spacing for product details, or employ hierarchical information architecture where primary information appears horizontally and secondary information appears vertically, effectively utilizing three-dimensional display space.

AI summary
Disclosed herein are electronic shelf-tag systems and methods thereof. For example, an electronic shelf-tag system includes, in some embodiments a fascia configured to mount to a shelf of a shelving unit and a light-emitting diode (“LED”) array coupled to the fascia. The LED array is configured to display product information in a shared electronic shelf tag for two or more products respectively stocked in two or more consecutive shelf slots when a horizontal resolution of a portion of the LED array corresponding to at least one shelf slot of the two or more consecutive shelf slots is insufficient for displaying the product information for the product stocked in the at least one shelf slot.
