Solution Overview
Problem
Users unfamiliar with the operation of box-shaped reading devices for RFID tags may perform improper operations, leading to delays in processing due to incorrect handling of the opening-and-closing lid during the reading process.
Innovation Solution
A reading device with a housing, antenna, opening-and-closing lid, detector, and alert unit that detects the open or closed state of the lid and provides alerts to guide users on proper operation methods, ensuring correct usage and preventing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the opening-and-closing lid is closed during reading to prevent read errors, then reading reliability is improved, but users unfamiliar with operations may forget to open the lid or open it during reading, causing processing delays
Solution Approach 1:
The system implements feedback by detecting the open/closed state of the lid during reading operations and providing real-time alerts to users. The alert unit notifies users when the lid is opened during reading or not opened after reading completion, guiding proper operation and preventing processing delays while maintaining reading reliability.
Solution Approach 2:
The system performs preliminary detection of the lid state before and during reading operations. By detecting whether the lid is properly closed before starting reading and monitoring its state throughout the process, the system can proactively issue alerts to prevent improper operations that would cause delays.
2Ease of operation
If the lid state is monitored and alerts are provided to guide users, then ease of operation is improved, but device complexity increases due to additional detector and alert unit components
Solution Approach 1:
The detector and alert unit serve multiple functions: detecting lid state, determining reading operation status, and providing guidance alerts to users. This multi-functionality improves ease of operation while minimizing the increase in device complexity by making the additional components perform several related tasks.
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
The device effectively guides users to maintain the lid in the correct state during reading and after completion, preventing errors and ensuring efficient processing by issuing alerts when the lid is opened during reading or left closed after processing is finished.
