Adjustable Screen POS Device for Dynamic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Point-of-sale devices and self-checkout terminals often face inefficiencies due to inflexible configurations, leading to underutilization of space and resources during varying business conditions, as they cannot quickly adapt between point-of-sale and self-checkout applications to match changing customer throughput.
Innovation Solution
A configurable point-of-sale device equipped with an adjustable screen and an accelerometer, where the processor analyzes orientation data to determine the screen's position and orientation, allowing it to automatically switch between point-of-sale and self-checkout applications based on the screen's position and orientation, enabling easy configuration by simply moving the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the point-of-sale device has a fixed configuration, then the device structure is simple and stable, but the device cannot adapt to changing business conditions and checkout volume
Solution Approach 1:
The patent applies the dynamics principle by making the screen position adjustable between a first position for point-of-sale operation and a second position for self-checkout operation. The screen can be physically moved between these positions to change the device's functional configuration, allowing it to adapt to varying business needs while maintaining a relatively simple overall device structure.
2Adaptability or versatility
If the point-of-sale device is configured for point-of-sale operation, then it can serve cashiers efficiently, but it cannot be used during slow periods when self-checkout is needed
Solution Approach 1:
The device enables dynamic switching between point-of-sale and self-checkout modes by physically moving the screen between predefined positions. This mechanical adjustment allows the device to adapt its function based on business conditions without requiring complex software reconfiguration or manual intervention, thereby minimizing time loss.
Solution Approach 2:
The system incorporates self-service elements where the device automatically detects the screen position and configures the appropriate application accordingly. When the screen is moved to the first position, the point-of-sale application is automatically launched, and when moved to the second position, the self-checkout application is automatically launched, eliminating the need for manual reconfiguration.
3Productivity
If multiple point-of-sale devices are deployed, then customer service capacity increases, but space utilization decreases during slow periods
Solution Approach 1:
The patent implements multi-functionality by enabling a single point-of-sale device to serve dual purposes: it can operate as a traditional point-of-sale device when the screen is in the first position, and as a self-checkout terminal when the screen is in the second position. This universality allows the same physical device to fulfill different functional roles based on business demand, improving space utilization during slow periods.
4Ease of operation
If the device requires manual configuration for mode switching, then the configuration process is controlled and verified, but the configuration process is time-consuming and labor-intensive
Solution Approach 1:
The system performs self-service configuration by automatically detecting the screen's physical position through position detection mechanisms and autonomously launching the appropriate application. When the screen is moved to the first position, the system automatically detects this and launches the point-of-sale application without requiring manual intervention. Similarly, movement to the second position automatically triggers the self-checkout application launch, eliminating configuration time and labor requirements.

Function Achieved in This Case
This solution allows for efficient use of space by enabling quick switching between applications, optimizing customer throughput and resource utilization by allowing cashiers to easily convert between point-of-sale and self-checkout modes without the need for manual intervention.
Implementation Method 1
The adjustable screen includes an accelerometer. The accelerometer is configured to generate orientation data. The orientation data corresponds to the adjustable screen.
Data Source
AI summary
A point-of-sale device including an adjustable screen, an accelerometer, and a processor is provided. The adjustable screen is arranged in a cashier position or a customer position. The accelerometer generates orientation data corresponding to the adjustable screen. The processor determines, via an accelerometer driver, an adjustable screen position based on the orientation data. The processor then generates, via the accelerometer driver, a position change notification if the adjustable screen changes position. The processor then provides the position change notification and the adjustable screen position to an application selector. The processor then launches, via the application selector upon receiving the position change notification, an application based on the adjustable screen position. In one example, the launched application is a point-of-sale application if the adjustable screen position is the cashier position. In another example, the launched application is a self-checkout application if the adjustable screen position is the customer position.
