Unified Operator Selection Screen for ECR Authority Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sales data processing apparatuses, such as ECRs, require cumbersome processes for adding or removing operator authorities, involving separate tab or screen management for each operator position, which is inefficient and time-consuming.
Innovation Solution
A sales data processing apparatus and method that associate operator groups with predetermined conditions, generating an operator selection screen by linking operators to tabs or screens based on set criteria, allowing easy management and display of operator permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate tabs or screens are created for each operator position, then operator authority management is achieved, but the process of adding or removing operators becomes troublesome and time-consuming
Solution Approach 1:
The patent combines multiple operator position tabs into a single unified operator selection screen. Instead of maintaining separate tabs for each position (cashier, manager, administrator), the system displays all operators across all positions on one screen, allowing selection without navigating through multiple separate tabs. This merging eliminates the need to create or delete tabs when operators are added or removed, significantly reducing the time and complexity of operator management while maintaining proper authority control.
2Ease of operation
If operator keys are positioned in separate tabs for each position, then authority restriction is implemented, but operator key management becomes complex when operators are added or deleted
Solution Approach 1:
The patent merges operator keys from multiple position-specific tabs into a single unified selection screen. All operator keys (cashier, manager, administrator) are displayed together on one screen with visual indicators showing their respective positions and authorities. This approach maintains authority restriction through clear visual differentiation while eliminating the complexity of managing separate tabs and repositioning keys when operators are added or removed.
Solution Approach 2:
The patent uses visual differentiation (such as color coding or icon indicators) to distinguish operator keys by position and authority level on the unified selection screen. Different colors or symbols indicate different roles (cashier, manager, administrator), allowing the system to maintain ease of operation with clear authority indication while simplifying the underlying management structure.
3Adaptability or versatility
If multiple tabs are used for different operator positions, then authority-based access control is achieved, but the number of screens and tabs increases system complexity
Solution Approach 1:
The patent consolidates multiple position-specific tabs into a single operator selection screen that displays all operators regardless of position. The system maintains adaptability and versatility by clearly indicating each operator's position and authority through visual cues (icons, color codes, or position labels), allowing proper access control to be enforced while dramatically reducing the number of tabs and screens the system must manage.

AI summary
A sales data processing apparatus includes the following. An operation unit is associated with a display and receives operation by touch. A setting unit associates an operator group with each operator according to a predetermined condition and associates a predetermined number of operator groups with each tab or each screen displayed on the display. A display control unit generates an operator selection screen to select the operator based on contents set by the setting unit and displays the operator selection screen on the display.
