RFID List Display Update for Inventory Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RFID reader writers used in stock management often have small displays, leading to inaccurate inventory checks and stock checks due to partial or fine displays when handling a large quantity of commodities.
Innovation Solution
An information registering apparatus and method that includes a list creating unit, list display unit, and list-display updating unit to arrange and update records of identification information from radio IC tags, prioritizing recently read records to the top of the list for improved visibility and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a small display screen is used in the RFID reader writer, then the device can be portable and carried easily, but the display becomes partial or fine making inventory check inaccurate
Solution Approach 1:
The patent transitions the display from a two-dimensional small screen to a three-dimensional physical list structure where records can be arranged vertically with recent readings at the top. This spatial reorganization allows comprehensive information display within the portable device's display constraints, maintaining both portability and inventory check accuracy.
2Loss of information
If a large number of commodity information records are displayed simultaneously, then complete inventory information is provided, but the display becomes crowded and hard to read on a small screen
Solution Approach 1:
The patent segments the commodity information records into a structured list format with hierarchical organization. Recent readings are separated and placed at the top, while other records follow in order, creating distinct visual segments that are easier to process on a small screen while maintaining complete information.
Solution Approach 2:
The list display is designed to be dynamic, automatically reorganizing records based on reading timing. As new readings occur, the list updates to maintain the most recent information at the top, providing adaptive information presentation that maintains readability while preserving complete inventory data.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances work efficiency by providing an accurate and comprehensible inventory check even for large quantities of commodities, ensuring precise information display and reducing errors.
Implementation Method 1
a small medium that incorporates an IC chip and an antenna and performs communication with a dedicated reader writer in a non-contact manner via the antenna

AI summary
In a state in which a list generated by arranging a large number of records including at least identification information, which are stored by radio IC tags, for individually identifying objects and information derived from the identification information is acquired and displayed, the information stored by the radio IC tags is read. Then, the list is updated to and displayed in a state in which the records of the list including the read information stored by the radio IC tags are moved to the top of the list in order of the reading. Therefore, even when inventory of a large quantity of commodities is performed, it is possible to provide a customer with information concerning inventory check in an accurate and comprehensible form. As a result, it is possible to improve work efficiency of the user.
