Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin receiving devices face performance issues when handling large amounts of coins, leading to jams and potential damage from foreign matters, especially when the coin separating unit is overloaded.
Innovation Solution
An active type feeder with a vibratory feed module and a transfer module, including a guide face with recesses and a rotatable blocking element, is used to regulate the coin feed rate and prevent jams, while a detector module ensures the coin separating unit is not overloaded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a passive guide face is used to feed coins to the coin separating unit, then the device structure is simple, but the device cannot handle large amounts of coins efficiently and experiences jams and overload
Solution Approach 1:
The patent applies the dynamics principle by transforming the static passive guide face into an active vibratory feed module. The guide face is now capable of vibration to actively transport coins toward the coin separating unit, enabling the system to handle large amounts of coins efficiently while maintaining controlled feed rates to prevent jams and overload conditions.
Solution Approach 2:
The patent directly applies mechanical vibration by equipping the feed module with a vibratory guide face that generates vibrations to move coins along the feeding path. This vibratory mechanism ensures reliable coin transport, controls the feed rate to match the separating unit's capacity, and prevents accumulation that would lead to jams and overload situations.
2Speed
If coins are fed rapidly to the coin separating unit, then processing speed increases, but the coin separating unit becomes overloaded and jams occur
Solution Approach 1:
The patent applies feedback by implementing a detector module that monitors the coin stock in the lower portion of the base plate and the operational state of the coin separating unit. This feedback mechanism allows the vibratory feed module to adjust its coin feed rate dynamically, ensuring that coins are fed at a speed that the separating unit can handle without becoming overloaded or jammed, thus maintaining high reliability.
Solution Approach 2:
The patent uses dynamics by making the coin feed rate adjustable and responsive to system conditions. The vibratory feed module can vary its feeding speed based on the separating unit's current load and performance, allowing rapid feeding when capacity is available while slowing down or stopping when the unit approaches overload, preventing jams and maintaining reliable operation.
3Reliability
If foreign matters are present on coins, then coin separation function and unit performance are adversely affected, but no cleaning mechanism is provided
Solution Approach 1:
The patent applies preliminary action by incorporating recesses in the guide face that actively remove foreign matters from coins during the feeding process, before the coins reach the coin separating unit. This preliminary cleaning action prevents foreign substances from interfering with the separation function or damaging the unit, improving reliability without requiring a separate complex cleaning mechanism.
Solution Approach 2:
The patent converts the potentially harmful presence of foreign matters into a beneficial cleaning function. The recesses in the guide face are designed to exploit the coin feeding process itself to remove contaminants, turning the feeding mechanism into a dual-purpose system that both transports coins and cleans them, thereby protecting the separation function without adding significant complexity.
4Productivity
If the coin separating unit handles large coin volumes, then productivity increases, but the unit may be damaged by foreign matters and overload
Solution Approach 1:
The patent applies preliminary action by cleaning coins of foreign matters during the feeding process through the recessed guide face, before they enter the coin separating unit. This preliminary cleaning protects the separating unit from damage by foreign substances, allowing it to handle large coin volumes continuously without degradation, thus maintaining both high productivity and durability.
Solution Approach 2:
The patent uses dynamics by implementing a controllable feed rate mechanism that adapts to the separating unit's capacity and condition. The vibratory feed module can adjust the coin feed rate to prevent overload conditions, allowing the unit to process large volumes sustainably without exceeding its load capacity, thereby maintaining both high productivity and structural integrity over time.
