Variable Speed Coin Transport Control for Transaction Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin handling devices operate at a fixed, relatively low speed to ensure authenticity checking, leading to inefficient performance and prolonged transaction times, as they must accommodate the most complex currency, even when authenticity verification is unnecessary.
Innovation Solution
A coin handling device with a control unit that adjusts the transport speed based on different operating modes, allowing for optimized speed selection depending on the situation, such as during scheduled or aborted transactions, and varying currency complexities, to ensure efficient and safe handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conveyor belt is driven at a fixed low speed to ensure reliable authenticity checking, then the authenticity verification reliability is improved, but the device performance and transaction speed deteriorate
Solution Approach 1:
The conveyor belt speed is changed from a fixed value to a dynamically adjustable parameter. The control unit varies the transport speed based on different operating situations (normal operation vs. aborted transaction), allowing the system to adapt its performance characteristics to match the current operational context, thereby resolving the contradiction between reliability and productivity.
Solution Approach 2:
The transport speed parameter is modified according to different operational states. During normal operations, a lower speed is maintained for reliable authenticity checking, while during aborted transactions, the speed is increased to quickly clear coins from the input unit, thus optimizing both reliability and productivity under different conditions.
2Reliability
If the conveyor belt is driven at a fixed low speed to accommodate the most complex currency, then the detection reliability for complex currencies is improved, but the handling speed for simpler currencies deteriorates
Solution Approach 1:
The system dynamically adjusts the conveyor belt speed based on the complexity of the currency being processed. For complex currencies requiring thorough verification, the speed is reduced to ensure reliable detection. For simpler currencies, the speed is increased to improve handling efficiency, thus resolving the contradiction between detection reliability and handling speed.
3Reliability
If the conveyor belt is driven at a fixed low speed to ensure safe handling, then the safety of coin transport is improved, but the transaction processing time deteriorates
Solution Approach 1:
The transport speed is dynamically adjusted based on the operational context. During normal transactions, a lower speed ensures safe and reliable handling. During aborted transactions, the speed is increased to quickly clear the input unit, reducing the time loss associated with aborting transactions while maintaining safety during normal operations.
