Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a store mobile terminal device is used for pre-handling product registration, it is challenging to identify the store clerk who performed the registration after the settlement process.
Innovation Solution
A store mobile terminal device and payment device system that includes a reception means for inputting clerk identification, a product information acquisition means, and an output means for generating payment information with clerk identification, enabling the payment device to read and settle transactions while issuing a receipt with clerk identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a store mobile terminal device is used as a product registration device for pre-handling, then productivity is improved by allowing product registration before settlement, but it becomes difficult to identify which store clerk performed the product registration after settlement
Solution Approach 1:
The system performs preliminary product registration using the store mobile terminal device before the settlement process. The store clerk inputs product information in advance, and the system stores this information with associated clerk identification, enabling efficient pre-handling while preserving accountability information for later retrieval.
Solution Approach 2:
The system introduces an intermediary mechanism (the store mobile terminal device with integrated reception means, product information acquisition means, and output means) that bridges product registration and settlement processes. This intermediary captures and transmits clerk identification information through payment information that is readable by the payment device, ensuring continuous traceability.
2Ease of operation
If the store mobile terminal device is used for pre-handling product registration, then ease of operation is improved, but the device complexity increases to maintain clerk identification through the settlement process
Solution Approach 1:
The store mobile terminal device is designed with multi-functionality, serving both as a product registration device and maintaining clerk identification capabilities. The device integrates reception means for clerk identification, product information acquisition means, and output means for payment information, allowing one device to perform multiple functions without requiring separate specialized equipment.
Solution Approach 2:
The system merges the product registration function and clerk identification function into a single integrated process. The reception means that receives clerk identification, the product information acquisition means, and the output means work together as a unified system, combining multiple functions into one cohesive device operation.

AI summary
A reception unit receives an input of identification information of a store clerk. A product information acquisition unit acquires product information of a product that is purchased by a customer in accordance with the store clerk's operation. An output unit outputs settlement information for the product that includes the identification information of the store clerk, relates to payment based on the product information, and can be read by a settlement device. The settlement device reads the settlement information. The settlement device uses the read settlement information to settle the payment. The settlement device issues a receipt that includes the identification information of the store clerk included in the settlement information.
