Terminal Control System for Flexible Product Registration Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customers may find it inconvenient to operate terminal devices during shopping, particularly when they want to continuously read product information or check registered products, as existing systems do not offer flexible modes for product registration.
Innovation Solution
A control system that includes a registration means, a mode reception means, and a display control means to allow customers to switch between a sequential checking mode and a continuous mode on the terminal device, enabling them to choose how to interact with product information and registration screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed operation mode is used for product registration, then the system is simple to implement, but customer convenience deteriorates due to inability to adapt to different shopping preferences
Solution Approach 1:
The system dynamically switches between sequential checking mode and continuous scanning mode based on customer selection. The display control unit adapts the operational state in real-time, allowing the same terminal device to serve different customer preferences without requiring multiple dedicated devices.
Solution Approach 2:
A single terminal device is designed to perform multiple functions by supporting both sequential checking mode and continuous scanning mode. This multi-functionality eliminates the need for separate devices for different shopping styles, improving adaptability while maintaining reasonable system complexity.
2Ease of operation
If the terminal device requires unique operation steps, then the system is easy to control, but ease of operation deteriorates as customers feel inconvenient during shopping
Solution Approach 1:
The system performs preliminary action by automatically registering products in the background without requiring customers to manually check each product. In continuous scanning mode, the terminal device continuously reads and registers products automatically, reducing the number of operations customers need to perform and improving ease of operation.
Solution Approach 2:
The terminal device provides self-service functionality where the system automatically handles product registration and screen switching based on the selected mode. Customers simply need to select their preferred mode once, and the system takes care of the remaining operations automatically, significantly improving ease of operation.
3Productivity
If the reading screen is displayed continuously, then continuous scanning is enabled, but information feedback to customer deteriorates due to lack of visual confirmation of registered products
Solution Approach 1:
The display functionality is segmented into different modes: sequential checking mode provides visual feedback by displaying each registered product individually, while continuous scanning mode prioritizes scanning speed. This segmentation allows the system to optimize for either information feedback or productivity depending on customer preference, resolving the contradiction between the two requirements.
Solution Approach 2:
The display mode dynamically adapts based on customer selection. When sequential checking mode is selected, the system provides detailed visual feedback. When continuous scanning mode is selected, the system prioritizes scanning speed while still providing necessary information. This dynamic adaptation resolves the contradiction between productivity and information feedback.

AI summary
This control system including: a registration unit configured to register, when identification information is read on a reading screen capable of reading the identification information about a product by an operation by a customer on the terminal device, the product indicated by identification information in a list; a mode reception unit configured to receive one of a sequential checking mode in which a list screen of the list is displayed when the identification information is read and a continuous mode in which the reading screen is displayed when the identification information is read; and a display control unit configured to display a screen related to the received mode on the terminal device.
