Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic shelf labels have limited display areas, failing to meet the needs of large commodities or those requiring more information display, and are inefficient due to manual replacement of traditional paper labels.
Innovation Solution
A multi-screen electronic shelf label with a power supply, multiple screens, a master control chip, an antenna circuit, a screen driving circuit, and an RGB lamp circuit, enabling wireless communication and flexible, efficient display of information across multiple screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single-screen electronic shelf label is used, then the device complexity is low, but the display area is limited and cannot meet the needs of large commodities or those requiring more information display
Solution Approach 1:
The electronic shelf label is divided into multiple independent screens (first screen, second screen, etc.), each capable of displaying information independently. This segmentation allows the total display area to be expanded while each individual screen module remains relatively simple in structure, resolving the contradiction between large display area and device complexity.
2Productivity
If traditional paper labels are used, then the device complexity is low, but the shelf management efficiency is low due to manual replacement
Solution Approach 1:
The patent replaces the mechanical manual replacement process of paper labels with an electronic display system controlled by a master control chip. The master control chip wirelessly controls multiple screen modules to display commodity information, eliminating the need for manual intervention and significantly improving shelf management efficiency despite the increased electronic complexity.
3Area of stationary object
If a multi-screen electronic shelf label is used, then the display area is enhanced, but the power consumption increases
Solution Approach 1:
The patent implements periodic scanning control of the multiple screen modules through the master control chip, rather than keeping all screens continuously active. The chip sequentially activates different screen modules to display information, which reduces overall power consumption compared to having all screens operating simultaneously, while still providing adequate display area for large commodities.
