Solution Overview
Problem
Opticians face difficulties in efficiently tracking the progress of eyeglasses being made, including detecting delays or anomalies, and locating specific trays, which leads to potential errors and increased search time for both opticians and customers.
Innovation Solution
A device utilizing electronic and computer systems to track the location and progress of trays through radio-identification devices, barcode readers, and a database management system, allowing for quick identification and updating of tray positions and manufacturing stages, thereby facilitating accurate tracking and communication of delivery status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual review of each tray is used to track progress, then complete monitoring is achieved, but time consumption and labor effort increase significantly
Solution Approach 1:
The system enables self-monitoring through automated tracking. Each tray is equipped with identification means (RFID tags, barcodes, or QR codes) that automatically transmit location and status information to the central management system without requiring manual intervention. The system autonomously monitors tray positions, manufacturing progress, and delivery status, eliminating the need for opticians to manually review each tray while maintaining complete monitoring coverage.
Solution Approach 2:
The patent replaces manual mechanical tracking with electronic and digital systems. Instead of physically reviewing each tray, opticians use a central management system with software that processes electronic signals from RFID readers, barcode scanners, or QR code readers. This substitution of mechanical manual inspection with electronic automation significantly reduces time consumption while maintaining reliable monitoring.
2Adaptability or versatility
If manual search for trays is used to locate specific glasses, then complete search capability is achieved, but search time increases significantly
Solution Approach 1:
The system enables automatic location and identification of trays. Each tray carries unique identification means (RFID tags, barcodes, or QR codes) that automatically transmit their location and status to the central management system. When an optician needs to locate a specific tray, the system can actively search for and display the tray's location information, or the tray can passively be detected by readers, eliminating manual searching.
Solution Approach 2:
The patent replaces manual physical search with electronic detection and digital display systems. RFID readers, barcode scanners, or QR code readers automatically detect tray locations and transmit this information to a central management system that displays tray positions on screens or prints location data, substituting the time-consuming manual search process with rapid electronic detection and information retrieval.
3Productivity
If electronic tracking systems are implemented, then tracking efficiency is improved, but device complexity increases
Solution Approach 1:
The system divides the tracking function into separate, independent components: identification means attached to each tray (RFID tags, barcodes, or QR codes), portable or fixed readers for detecting identification, and a central management system for processing information. This segmentation allows each component to be simple and inexpensive while the collective system achieves efficient tracking. The identification means remain with the trays throughout their journey, while readers and processing systems are distributed where needed.
Solution Approach 2:
The patent uses identification means (RFID tags, barcodes, or QR codes) as intermediary elements that carry information about trays without requiring complex integration. These intermediaries bridge the gap between physical trays and the electronic management system, enabling tracking through simple attachment and detection mechanisms rather than complex embedded systems. The intermediaries transmit location and status information passively or actively without requiring power sources or complex electronics in the trays themselves.
4Reliability
If manual verification of delivery dates is used, then complete verification is achieved, but error risk increases
Solution Approach 1:
The system enables automatic verification of delivery dates and progress status. The central management system continuously monitors tray positions and manufacturing progress through electronic signals from RFID readers, barcode scanners, or QR code readers. Delivery dates and progress information are automatically updated and stored in the system, allowing for instant verification without manual intervention. The system autonomously compares current progress against scheduled delivery dates and can generate alerts for potential delays.
Solution Approach 2:
The patent replaces manual verification with electronic data processing and automated comparison systems. The central management system uses software that automatically retrieves tray progress information, compares it against scheduled delivery dates, and determines whether delays have occurred. This electronic verification process eliminates human error in date comparison while maintaining complete verification coverage and significantly reducing the time required for verification.
