Rotating POS Terminal Layout for Attended and Self-Checkout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional point-of-sale systems lack flexibility and efficiency in operation, and inventory management is labor-intensive, requiring dedicated employees for counting, reporting, and tracking stock levels.
Innovation Solution
A point-of-sale system with a rotating video terminal for attended and self-service modes, integrated with wireless communication for mobile transactions, and an inventory monitoring system that allows for automated data entry and reporting, enabling efficient inventory management and reduced manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated terminals are provided for attended checkout and self-service checkout separately, then each terminal type can be optimized for its specific function, but the system lacks flexibility and requires more terminal devices
Solution Approach 1:
The patent applies multi-functionality by designing a single checkout terminal that can operate in both attended and self-service modes. The terminal includes a rotatable display device that can be positioned in different orientations to accommodate different service modes, and a control device that can switch between attended and self-service operational modes, allowing one terminal to replace what would traditionally require two separate terminals
Solution Approach 2:
The patent applies dynamics through the rotatable display device that can change its orientation dynamically. The display can be rotated between a first position for attended checkout mode and a second position for self-service mode, allowing the terminal's configuration to adapt to different operational requirements rather than being fixed in a single state
2Measurement precision
If employees are assigned to physically locate, count, and track inventory, then inventory management can be performed accurately, but labor costs and time consumption increase
Solution Approach 1:
The patent applies self-service by implementing an automated inventory monitoring system that continuously tracks inventory levels without requiring employee intervention. The system automatically detects when inventory is depleted or below threshold levels and generates notifications, allowing the inventory management process to serve itself rather than requiring dedicated human labor for counting and tracking
Solution Approach 2:
The patent applies feedback through an automated notification system that provides real-time information about inventory status. When inventory levels fall below predetermined thresholds or items are depleted, the system automatically generates and sends notifications to relevant personnel, creating a continuous feedback loop that maintains accurate inventory knowledge without requiring manual counting
3Reliability
If employees manually generate inventory reports and place purchase orders, then inventory replenishment can be controlled, but productivity decreases and labor costs increase
Solution Approach 1:
The patent applies self-service by implementing an automated system that generates inventory reports and places purchase orders without employee intervention. The system continuously monitors inventory levels, automatically generates reports when replenishment is needed, and can even initiate purchase orders, allowing the inventory management process to handle its own replenishment needs
Solution Approach 2:
The patent applies preliminary action by proactively monitoring inventory levels and generating notifications before inventory is completely depleted. The system maintains inventory above predetermined threshold levels through advance detection and notification, preventing stockouts rather than reacting after depletion occurs

AI summary
A point-of-sale system includes: a check-out terminal having a cash drawer; and a video terminal coupled to a rotating base. In an attended check-out terminal mode the video terminal is configured to be rotated on the rotating base to a first position such that a display screen of the video terminal is approximately parallel with a front surface of the cash drawer, and in a self-service check-out terminal mode the video terminal is configured to be rotated on the rotating base to second position such that the display screen of the video terminal is approximately perpendicular to the first position.
