Dual-Side Coin Handling Device for Simultaneous Supply and Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the retail sector, the personal handover of coins between retail firms and security transport companies is time-consuming and costly due to the need for direct personnel involvement, and existing coin handling devices do not facilitate efficient separation of coin supply and disposal processes.
Innovation Solution
A coin handling device with dual supply units, one for retail employees and another for security transport companies, along with a coin processing unit and storage system, allows for simultaneous operation without user interference, includes authentication and inventory management, and enables secure, efficient sorting and dispensing of coins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single supply unit is used for both retail employees and security transport company, then device complexity is reduced, but personnel expenses and time consumption increase due to manual handover requirements
Solution Approach 1:
The device is divided into two separate supply units (first supply unit for retail employees, second supply unit for security transport company) located at opposite sides of the device. This segmentation allows independent operation by different user groups simultaneously, eliminating the need for manual handover and reducing time loss while maintaining manageable device complexity through modular design
2Adaptability or versatility
If employees of retail firm are involved in coin handover, then operational flexibility is maintained, but personnel expenses increase due to second set of eyes principle
Solution Approach 1:
The device enables self-service operation where the security transport company can independently supply coins through the second supply unit without requiring retail firm employees to be present. The automated coin processing unit handles sorting and storage, eliminating the need for employee involvement in manual handover and reducing personnel expenses while maintaining operational flexibility
3Reliability
If coin supply depends on employee attendance time, then operational control is maintained, but productivity decreases due to scheduling constraints
Solution Approach 1:
The device allows preliminary action by enabling the security transport company to supply coins at any time through the second supply unit without waiting for employee availability. The automated system immediately processes the coins through the coin processing unit, eliminating scheduling constraints and improving productivity while maintaining operational control through the control unit
4Area of stationary object
If both supply units are placed at the same side of the device, then device compactness is improved, but user interference occurs when both units are used simultaneously
Solution Approach 1:
The two supply units are positioned at opposite sides of the device along the horizontal dimension, providing spatial separation that prevents user interference when both units are used simultaneously. This dimensional arrangement maintains device compactness while ensuring operational independence for different user groups
