Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tracking methods are used for table status, then system complexity is low, but productivity and table turnover efficiency deteriorate
Solution Approach 1:
The patent replaces manual mechanical tracking methods with automated electronic detection systems. Mobile devices equipped with NFC readers, RFID readers, QR code scanners, or barcode scanners automatically detect table status by reading tags on table surfaces, eliminating the need for manual checking and paperwork. This substitution of mechanical/manual operations with electronic automation directly improves table turnover efficiency while the modular nature of the system keeps complexity manageable.
Solution Approach 2:
The system enables tables to effectively report their own status through the detection tags (NFC, RFID, QR code, or barcode) that are permanently attached to each table. When a mobile device scans these tags, the table's status information is automatically captured and transmitted to the central server without requiring manual input from staff, thus improving productivity while minimizing system complexity.
2Productivity
If automated detection systems are implemented, then productivity improves, but device complexity increases
Solution Approach 1:
The patent employs mobile devices that can perform multiple functions: they serve as detection devices for reading table status tags, as communication devices for transmitting data to the server, and as user interface devices for displaying information to staff and customers. This multi-functionality consolidates what would otherwise require separate specialized devices, thereby improving employee productivity while preventing device complexity from escalating.
Solution Approach 2:
The system introduces a central server as an intermediary that manages the complexity of data processing, storage, and analysis. Mobile detection devices communicate status information to the server, which then handles the complex tasks of tracking table status, generating analytics, and providing recommendations. This intermediary approach allows employee-facing devices to remain relatively simple while still achieving high productivity through centralized intelligent processing.
3Measurement precision
If real-time table status tracking is implemented, then information accuracy improves, but loss of time in data collection decreases (i.e., more time is required)
Solution Approach 1:
The system performs preliminary detection of table status automatically as soon as a mobile device comes within range of a table's detection tag. The status is captured in real-time without requiring manual intervention or subsequent data entry, thus achieving high measurement precision (accurate real-time status tracking) while minimizing the time loss associated with data collection.
Solution Approach 2:
The system maintains continuous monitoring of table status through automated detection tags that are always active on each table. Rather than periodically sampling table status or requiring manual checks at intervals, the system continuously tracks status changes in real-time, ensuring high measurement precision while the automated nature of the detection eliminates time loss from manual data collection processes.
4Adaptability or versatility
If multiple detection methods are provided (NFC, RFID, QR code, barcode), then adaptability improves, but device complexity increases
Solution Approach 1:
The system dynamically selects and employs the most appropriate detection method based on the specific table configuration and available technology. Each table can be equipped with different types of detection tags (NFC, RFID, QR code, or barcode), and the mobile detection devices are configured to automatically recognize and read the appropriate tag type. This dynamic adaptability allows the system to accommodate diverse implementation scenarios while the automated selection process prevents the complexity from becoming unmanageable.
