Order List Display for Cancelled Menu Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing order management systems in restaurants lack the ability to maintain a history of cancelled menu items, making it difficult for operators to track cancellations during checkout, which reduces operability and increases operator burden.
Innovation Solution
An order receiving apparatus and method that includes a display unit for listing ordered menu items, a receiving unit to identify and cancel orders, and a changing unit to change the display of cancelled items to a special format, allowing operators to easily track cancelled orders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the checkout apparatus deletes cancelled menu items from the order list, then the order list remains clean and simple, but the operator cannot track cancellation history during checkout
Solution Approach 1:
The patent applies color changes to visually distinguish cancelled menu items from active orders in the order list. Cancelled items are displayed in a different color (e.g., grayed out or highlighted), allowing operators to quickly identify and track cancellations without deleting the records. This resolves the contradiction by preserving cancellation history while maintaining operational convenience through visual differentiation.
2Loss of information
If the checkout apparatus maintains a history of cancelled menu items, then the operator can track cancellations, but the order list becomes more complex and harder to manage
Solution Approach 1:
By using color changes to mark cancelled items, the system preserves complete order history including cancellations while avoiding the need for complex separate tracking mechanisms. The visual distinction allows operators to process both active and cancelled items efficiently without increasing operational complexity.
Solution Approach 2:
The patent segments the order list display by visually separating cancelled items from active orders through color coding. This segmentation allows operators to quickly distinguish between different order states without creating separate data structures or complex management procedures, thus maintaining simplicity while preserving information.
3Ease of operation
If the checkout apparatus displays all order information in the same format, then the display is simple and consistent, but the operator cannot easily identify cancelled orders
Solution Approach 1:
The patent implements color changes in the display format to highlight cancelled orders. This allows all order information to be displayed in a single unified interface while using visual cues (color differentiation) to immediately identify cancelled items, eliminating the need for multiple display modes or complex filtering mechanisms.

AI summary
An order receiving apparatus includes: a display unit configured to display an order input screen including an order list in which order information indicating ordered menu items is list-displayed; a receiving unit configured to receive the order information indicating a menu item, an order of which is to be cancelled, among the pieces of order information list-displayed in the order list; a canceling unit configured to cancel the order of the menu item indicated by the received order information; and a changing unit configured to change display of the order information indicating the menu item, the order of which is cancelled, among the pieces of order information list-displayed in the order list to special display.
