Store Mobile Terminal Mode Switching for Clerks and Customers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Store mobile terminal devices are underutilized as they are primarily limited to self-scan shopping and lack flexibility in mode operation, restricting their functionality.
Innovation Solution
A store mobile terminal device that can switch between self-scan mode for customer operation, emergency mode for store clerk operation, and pre-handling mode, allowing product registration and payment processing based on the mode, enabling broader utilization and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the store mobile terminal device is limited to self-scan shopping mode, then the operation interface can be simplified for customers, but the device utilization efficiency decreases
Solution Approach 1:
The terminal device dynamically switches between customer mode and store clerk mode based on operational needs. The mode switching mechanism allows the device to adapt its functionality and interface complexity, enabling it to serve both customers for self-scan shopping and store clerks for emergency situations, thereby improving overall utilization efficiency while maintaining ease of operation for each user type
2Productivity
If the store mobile terminal device supports multiple modes (customer mode and store clerk mode), then the device utilization efficiency improves, but the device complexity increases
Solution Approach 1:
The terminal device is designed with multi-functionality to serve both customers and store clerks. By integrating customer mode for self-scan shopping and store clerk mode for emergency operations into a single device, the system achieves universal applicability. This eliminates the need for separate dedicated devices, improving utilization efficiency while the mode switching mechanism manages the complexity through standardized protocols and interfaces

AI summary
A reception unit receives a mode. The reception unit receives a customer mode or a clerk mode. If the received mode is the customer mode, an acquisition unit acquires, by an operation of a customer, commodity information about a commodity purchased by the customer. If the received mode is the clerk mode, the acquisition unit acquires, by an operation of a clerk, commodity information about the commodity purchased by a customer. An output unit outputs payment information according to the mode on the basis of the commodity information.
