Self-POS Terminal Integrating Customer and External System Inputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of self-registration systems using information terminals in retail stores creates a need for separate checkout devices in the checkout room, increasing installation space requirements and maintenance costs.
Innovation Solution
A self-POS terminal is designed to function as both a full-self-handling checkout device and a checkout device for the self-registration system, allowing it to acquire product information from both customer input and an external system, enabling seamless checkout operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate checkout device is installed for the self-registration system, then the system can handle both full-self-handling and self-registration checkouts, but the installation space requirement increases and maintenance cost increases
Solution Approach 1:
The self-POS terminal is designed to perform multiple functions: it serves as both a full-self-handling checkout device and a checkout device for the self-registration system. The terminal can process product registration from either the self-POS interface or the information terminal, calculate charges, and handle payment for both types of checkouts, thereby eliminating the need for separate checkout devices.
2Adaptability or versatility

3Area of stationary object
If the self-POS terminal processes both full-self-handling and self-registration checkouts, then the installation space and maintenance cost are reduced, but the device complexity increases
Solution Approach 1:
The self-POS terminal is designed to perform multiple functions: it serves as both a full-self-handling checkout device and a checkout device for the self-registration system. The terminal can process product registration from either the self-POS interface or the information terminal, calculate charges, and handle payment for both types of checkouts, thereby eliminating the need for separate checkout devices.
Solution Approach 2:
The self-POS terminal acts as an intermediary that receives and processes information from two different sources: direct product registration from customers using the self-POS interface, and product registration data transmitted from the information terminal. The terminal integrates these two information streams and processes them through a unified checkout workflow, managing the complexity of handling multiple input sources.
Data Source
AI summary
A checkout device includes a first acquisition unit, a second acquisition unit, and a checkout unit. The first acquisition unit acquires information on a product to be purchased by a customer based on data input by the customer's operation on an input device. The second acquisition unit acquires, from an external system, information on a product to be purchased by a customer, the information stored in the external system, based on data input by the customer's operation on an information terminal. The checkout unit makes a checkout based on the information on the product acquired by the first acquisition unit and the second acquisition unit.
