Coin Dispensing Modules Parallel Payout Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coin dispensing devices in vending machines and similar systems are inefficient in dispensing multiple coins quickly and reliably, leading to longer payout times and potential errors due to the sequential dispensing of single coins.
Innovation Solution
A method utilizing multiple coin dispensing modules, each with two coin tubes of the same nominal value, allowing simultaneous activation to dispense multiple coins in a single cycle, controlled by a system that optimizes coin combinations for minimal dispensing cycles and balanced fill levels, with independent operation and fill level sensors to prevent jams and malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If coins are dispensed sequentially one after the other, then the device structure remains simple, but the payout time becomes excessively long
Solution Approach 1:
The coin dispensing device is divided into multiple independent coin dispensing modules, each capable of dispensing coins separately. This segmentation allows parallel operation of multiple modules to dispense multiple coins simultaneously, thereby increasing payout speed without requiring a completely complex new design.
Solution Approach 2:
Multiple coin dispensing modules are combined within a single device, with each module having its own drive mechanism. By merging these independent modules into one integrated system, the device achieves the capability to dispense multiple coins in parallel while maintaining a manageable structural complexity.
2Loss of time
If multiple coin dispensing modules are activated simultaneously, then payout time is reduced, but the risk of errors and jams increases
Solution Approach 1:
Each coin dispensing module operates independently with its own drive mechanism, allowing controlled simultaneous activation. This segmentation isolates potential errors to individual modules rather than affecting the entire system, maintaining reliability while enabling parallel operation.
Solution Approach 2:
The control system determines the optimal combination of coins to be dispensed before activation, and the fill level sensors monitor coin availability in advance. This preliminary planning and monitoring prevent errors during simultaneous dispensing operations.
3Productivity
If coins of the same nominal value are stored in a single coin tube, then the device structure is simple, but the dispensing of multiple coins of the same value requires multiple sequential cycles
Solution Approach 1:
Coins of the same nominal value are distributed across multiple coin tubes assigned to different dispensing modules. This segmentation allows parallel access to coins of the same value through different modules, enabling simultaneous dispensing without requiring a single large complex tube.
Solution Approach 2:
Multiple coin tubes can store coins of the same nominal value, making each tube a universal storage unit for that denomination. This multi-functionality approach allows any module with the appropriate coin tube to dispense coins of that value, increasing dispensing efficiency.
4Productivity
If the device operates with high speed parallel dispensing, then productivity increases, but wear and tear reduces device lifetime
Solution Approach 1:
The mechanical load is segmented across multiple independent modules, each handling a portion of the total dispensing workload. This distribution reduces the wear and tear on any single module, extending the overall device lifetime while maintaining high productivity through parallel operation.
Solution Approach 2:
The device dynamically balances the workload across multiple modules and monitors fill levels in real-time. This dynamic operation allows for optimized usage patterns that reduce excessive wear on individual components while maintaining high dispensing rates.
