Serving Tray Protection by Delivery Sequence for Wrong-Order Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for efficiently delivering ordered food to multiple tables while preventing wrong delivery and ensuring consistent service are inadequate, particularly in environments where electronic devices like robots are used to replace human labor.
Innovation Solution
An electronic device equipped with a processor, memory, and driver, which includes a plurality of serving trays and a protection module. The device determines a serving order based on items on the trays and order information, and while delivering items, it provides protection for serving trays with subsequent serving orders, preventing unauthorized access and ensuring correct delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple serving trays are delivered simultaneously to multiple tables, then service efficiency is improved, but the risk of wrong delivery increases
Solution Approach 1:
The system segments the delivery process by assigning unique identifiers to each serving tray and establishing separate delivery routes or sequences for different tables. The serving trays are processed individually through the delivery system even when multiple items are being delivered simultaneously, ensuring that each tray can be tracked and delivered to the correct destination without confusion.
Solution Approach 2:
The system implements feedback mechanisms where the electronic device continuously monitors the status of each serving tray during delivery, tracks its position, and confirms successful delivery to the intended table. This real-time feedback allows the system to detect and correct potential delivery errors before they result in wrong deliveries.
2Ease of operation
If employees place cooked food on robots without considering serving order and table position, then ease of operation is improved, but delivery precision deteriorates
Solution Approach 1:
The electronic device performs self-identification of serving trays and automatic determination of delivery sequences. The system autonomously identifies each tray's contents, matches them with corresponding order information, and establishes the correct delivery sequence without requiring employee input about serving orders or table positions. This self-service capability maintains ease of operation while ensuring delivery precision.
Solution Approach 2:
The system replaces manual tracking and ordering methods with electronic identification and automated sequence determination. Instead of relying on employees to physically organize trays in a specific order or manually track their destinations, the electronic device uses sensors, cameras, or RFID tags to automatically identify and track each tray, substituting mechanical organization with intelligent electronic management.
3Manufacturing precision
If protection is provided for serving trays with subsequent serving orders during delivery, then delivery accuracy is improved, but device complexity increases
Solution Approach 1:
The system establishes protection measures for serving trays in advance, before the actual delivery error could occur. By pre-determining the serving sequence and pre-establishing protection mechanisms for trays with subsequent orders, the system proactively prevents wrong deliveries rather than reacting to errors after they occur. This preliminary action simplifies the overall system by avoiding the need for complex real-time intervention mechanisms.

AI summary
An electronic device may be configured to, based at least on items on a plurality of serving trays and/or pieces of order information of a plurality of destinations, determine a serving order in which the items on the plurality of serving trays need to be delivered, and while an item is delivered to one destination among the plurality of destinations, provide protection for a serving tray to which a serving order subsequent to a serving order of the one destination is mapped.
