POS Terminal Balance Display and Change Reserve Input Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current change preparation processes for automatic change dispensers in retail settings are cumbersome, requiring manual input and calculation of change reserves, which can lead to errors and inefficiencies in preparing and managing balances for the next day.
Innovation Solution
A merchandise sales data processing apparatus with a POS terminal and automatic change dispenser system that simultaneously displays balance information and an input area for change reserves, allowing clerks to easily input and manage change reserves through a touch panel, facilitating accurate and efficient preparation of change reserves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clerk manually inputs change reserves information through separate screens (balance screen then input screen), then the change reserves can be prepared, but the operation process becomes complex and time-consuming
Solution Approach 1:
The patent combines the balance display screen and the change reserves input screen into a single integrated screen. This allows the clerk to view the current balance and input change reserves information simultaneously without navigating between multiple screens, thereby simplifying the operation process and reducing the steps required to prepare change reserves.
Solution Approach 2:
The display screen is designed to serve multiple functions: displaying the current balance, accepting change reserves input, and showing the calculated payment amount all in one interface. This multi-functional design eliminates the need for separate screens for each operation, improving ease of use while maintaining all necessary functions.
2Productivity
If the clerk uses separate screens for balance display and change reserves input, then data can be collected accurately, but the time required for change preparation increases
Solution Approach 1:
By merging the balance display and change reserves input into a single screen, the system eliminates the time required to navigate between screens and perform separate operations. The clerk can input change reserves information while the balance is displayed, and the system automatically calculates the payment amount, significantly reducing the total time required for change preparation.
Solution Approach 2:
The system automatically calculates the payment amount (today's sales amount minus change reserves) as soon as the change reserves information is input, without requiring additional manual calculation steps. This preliminary automatic calculation saves time and reduces the risk of calculation errors.
3Reliability
If manual calculation of payment amount is performed, then flexibility is maintained, but calculation errors may occur
Solution Approach 1:
The system automatically calculates and displays the payment amount based on the input change reserves information, providing immediate feedback to the clerk. This automatic calculation eliminates manual arithmetic errors and ensures accuracy, while the result is clearly displayed on the same screen for verification.
Data Source
AI summary
A merchandise sales data processing apparatus includes a display device and a first display control unit. The first display control unit displays balance information and an input area simultaneously on the display device. The balance information is information regarding balance of each denomination in an automatic change dispenser which deposits or dispenses money. The balance information is generated by a balance information generating unit. The input area receives, through an input device, the input of change reserves information regarding change reserves that should be prepared in the automatic change dispenser.
