Dual-Port POS Payment Device for Self-Service Coin and Bill Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing POS devices require customers to either give money to a clerk or perform multiple steps for payment settlement, which can be inefficient and inconvenient.
Innovation Solution
A POS device with dual input ports for currencies, allowing customers to directly input coins and bills into the settlement device without needing to hand them to a clerk, enabling simultaneous payment processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single input port is provided for currencies, then the device structure is simple, but the customer must hand money to the clerk which slows down the payment process
Solution Approach 1:
The single input port is divided into multiple input ports (first input port and second input port) that can simultaneously receive different types of currencies. This segmentation allows the customer to directly insert coins and bills without handing them to the clerk, thereby speeding up the payment process while maintaining a relatively simple overall device structure.
Solution Approach 2:
The customer is enabled to directly insert currencies into the settlement device through the multiple input ports without requiring clerk intervention. This self-service mechanism eliminates the need for the customer to hand money to the clerk, thus improving payment processing speed while the device structure remains manageable through the use of multiple independent input ports.
2Ease of operation
If multiple input ports are added for simultaneous currency insertion, then payment speed improves, but the device structure becomes more complex
Solution Approach 1:
The settlement device incorporates multiple independently positioned input ports (first input port for coins, second input port for bills) that can simultaneously receive different types of currencies. This segmentation enables the customer to conveniently insert different currencies without complex coordination, improving ease of operation while the modular port design keeps the overall structural complexity manageable.
Solution Approach 2:
The settlement device is designed with multiple input ports that can handle different types of currencies (coins and bills) simultaneously. This multi-functionality allows the device to accept various currency types through dedicated ports, enhancing customer convenience without requiring an overly complex structure, as each port serves a specific currency type.
3Productivity
If the settlement device processes only one type of currency at a time, then the internal processing is simple, but the payment process requires multiple steps
Solution Approach 1:
The settlement device segments the currency processing function into multiple input ports, each capable of simultaneously receiving different types of currencies. This segmentation allows the device to process coins and bills at the same time rather than sequentially, reducing the number of processing steps and improving settlement completion time while maintaining relatively simple internal processing for each currency type.
Solution Approach 2:
The multiple input ports enable continuous simultaneous processing of different currency types. While one port receives coins, another port can simultaneously receive bills, eliminating idle time between processing different currency types. This continuity of useful action speeds up settlement completion without significantly increasing the complexity of individual currency processing paths.
