RFID Magazine Management for Optical Disc Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of optical discs and data volume increases, managing multiple magazines becomes difficult due to the complexity of tracking and organizing the discs within the system.
Innovation Solution
A magazine management device that includes a case with partitions to store magazines, an antenna system for communicating with radio identifiers on each magazine, and an arithmetic processor to manage and identify the discs, allowing for efficient storage and retrieval of optical discs by reading and writing data without direct handling of individual discs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple magazines are stored to increase data capacity, then the data storage capability is improved, but the management complexity increases
Solution Approach 1:
The patent replaces manual mechanical management of optical discs with an automated radio frequency identification (RFID) system. The antenna automatically detects magazines containing optical discs through wireless communication, eliminating the need for manual tracking and organization. This substitution of mechanical management with automated electromagnetic detection resolves the contradiction by maintaining high storage capacity while reducing management complexity.
2Ease of operation
If manual handling of individual discs is used, then flexibility in disc selection is improved, but the time required for data operations increases
Solution Approach 1:
The system performs preliminary detection of magazines containing optical discs using RFID technology before actual data operations. The antenna continuously identifies and locates target magazines, preparing the system in advance for data retrieval or storage. This preliminary automated detection eliminates time-consuming manual searching while maintaining operational flexibility, as the system can quickly locate and access any specific disc based on stored information.
3Measurement precision
If magazines are stored in fixed orientations, then positioning precision is improved, but user convenience deteriorates
Solution Approach 1:
The RFID system provides self-service functionality by automatically detecting and identifying magazines regardless of their insertion orientation. The antenna can read radio identifiers from magazines in various positions and orientations, allowing the system to self-correct for positioning variations. This eliminates the need for users to precisely align magazines according to specific orientations, thereby improving user convenience while the system maintains sufficient positioning precision through automated detection capabilities.
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 system enables efficient management of multiple optical discs by allowing wireless communication with radio identifiers, reducing the time required for data operations and improving user convenience by allowing magazines to be inserted in various orientations, thus simplifying the process of identifying and accessing disc data.
Implementation Method 1
an antenna that transmits a radio wave for asking a radio identifier provided to the magazine for a response and receives a radio wave of the response transmitted from the radio identifier
