Electronic Price Tag Positioning via Graphic Code Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic price tags are inflexible in size and cannot be accurately positioned for multiple commodities, leading to inefficient use and increased costs due to the need for multiple tags for each commodity.
Innovation Solution
A method that uses graphic codes to update the position and size of electronic price tags, allowing a single larger tag to be used across multiple commodities by scanning commodity and position codes, enabling dynamic size adjustment based on commodity length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single electronic price tag corresponds to a single commodity in a one-to-one manner, then the positioning is accurate, but the number of electronic price tags required increases, leading to increased costs and reduced operational efficiency
Solution Approach 1:
The electronic price tag is designed to serve multiple commodities simultaneously through multi-functionality. By displaying multiple commodity information items on a single tag, the system eliminates the need for one-to-one correspondence between tags and commodities, thereby reducing the total number of tags required while maintaining accurate positioning through the selection of representative commodities.
Solution Approach 2:
Multiple commodity information items are merged and displayed on a single electronic price tag. The system combines information from multiple commodities into one unified display, allowing one tag to represent multiple commodities and thus reducing the quantity of tags needed in the system.
2Quantity of substance
If a large electronic price tag is used to replace several adjacent small tags, then the number of tags is reduced and operational speed is improved, but the positioning accuracy is lost and the tag cannot correspond to individual commodities
Solution Approach 1:
The electronic price tag implements local quality by displaying different types of information in different regions of the tag. The first region shows information for a representative commodity with accurate positioning, while the second region shows information for other commodities. This allows the tag to maintain positioning accuracy for the representative commodity while also providing information for multiple commodities overall.
3Ease of manufacture
If the electronic price tag size is fixed, then the manufacturing is simple, but the adaptability to different commodity configurations is limited
Solution Approach 1:
The system changes the parameter of information display rather than physical tag size. By dynamically adjusting which commodity information is displayed in different regions of the fixed-size tag based on commodity configurations, the system achieves adaptability to different commodity arrangements while maintaining manufacturing simplicity of fixed-size tags.

AI summary
A method for updating the position of electronic price tag by graphic code including: step 1, placing a plurality kinds of commodities on a commodity shelf, mounting an electronic price tag screen on the commodity shelf and below the commodities; step 2, displaying at least n position graphic codes with an even interval on the electronic price tag screen; step 3, carrying out a first scan to send the commodity information to a server; step 4, carrying out a second scan to check a position of the commodity; step 5, sending a plurality of size graphic codes with different size information to a position where the position graphic code in step 4 locates; step 6, selecting a size graphic code with a proper size for a third scan by the supermarket tally clerk; step 7, generating a commodity tag by the server.
