Wireless Tag Reader Input Disabling for Error Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless tag reader systems face errors due to interrupts from user input devices during the tag reading process, leading to inefficiencies and the need for operators to clear error states, especially as the number of tags read increases.
Innovation Solution
A wireless tag reader data processing apparatus with a processor that disables input from user devices like touch panels, keyboards, and scanners while the RFID reader is active, ensuring uninterrupted data reading and preventing errors by notifying users that other input devices are disabled during the reading process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the RFID reader collectively reads data from multiple wireless tags, then the productivity of the system is improved, but the processing time increases and the system becomes more susceptible to interrupts from other input devices
Solution Approach 1:
The system performs preliminary actions by disabling other input devices before the RFID reading process begins and re-enables them after completion. This preventive measure ensures that no interrupts can occur during the critical reading period, allowing the system to maintain high productivity without risking processing interruptions.
2Ease of operation
If the system allows simultaneous operation of multiple input devices, then the ease of operation is improved, but errors occur due to interrupts during tag reading
Solution Approach 1:
The system applies preliminary anti-action by disabling other input devices before the RFID reading process starts. This counter-measure prevents potential interrupts that would cause errors, thereby maintaining system reliability while still allowing easy operation of the RFID reader itself. The disabled state is temporary and automatically reversed after reading completes.
3Adaptability or versatility
If the system processes interrupts from user input devices during tag reading, then the adaptability to user operations is improved, but the processing efficiency decreases and error handling becomes necessary
Solution Approach 1:
The system extracts or removes the capability to process interrupts from other input devices during the RFID reading period. By taking out this potentially disruptive function temporarily, the system maintains high processing efficiency for tag reading without the overhead of handling unrelated user inputs. The input capability is restored after the reading process completes.

AI summary
A wireless tag reader data processing apparatus includes a reading device interface configured to receive data read from wireless tags by a reading device and a user input device interface configured to receive data from a user input device. A processor is configured to disable an input from the user input device while the reading device is reading the data of the wireless tag. The wireless tag reader data processing apparatus in some examples may be incorporated into a point-of-sale terminal.
