RFID Inventory Terminal With On-Screen Quantity Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inventory management systems using RFID tags cannot adjust the inventory quantity of displayed articles directly on the screen, limiting the accuracy of inventory management.
Innovation Solution
A terminal device with an article display unit and a quantity setting screen display unit that allows users to adjust the inventory quantity of articles displayed on the screen based on RFID tag information, enabling accurate inventory management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID tag information is displayed on the RFID reader screen, then article information can be read without moving articles from shelves, but inventory quantity cannot be adjusted on the screen
Solution Approach 1:
The patent merges the RFID reader functionality with inventory quantity adjustment capabilities by integrating a quantity setting screen display unit into the RFID reader terminal. This allows the single device to both read RFID tag information and adjust inventory quantities directly on its display screen, eliminating the need for separate input devices and resolving the contradiction between ease of operation and management accuracy.
Solution Approach 2:
The RFID reader is enhanced to perform multiple functions: reading RFID tag information, displaying article information, and adjusting inventory quantities. By making the terminal device universal and multi-functional, the system improves operational ease while maintaining or enhancing inventory management accuracy through integrated control.
2Reliability
If additional input devices are used for inventory adjustment, then inventory quantity can be modified, but the process becomes more complex
Solution Approach 1:
The patent combines the inventory adjustment function directly into the RFID reader's display interface. The quantity setting screen display unit allows inventory modification through the existing terminal device without requiring additional input devices, thus maintaining inventory management accuracy while reducing system complexity.
Solution Approach 2:
The RFID reader terminal serves itself by integrating both reading and inventory adjustment functions within the same device. The terminal device performs inventory management operations autonomously without needing external input devices, simplifying the overall system configuration while maintaining operational reliability.
