Coin Storage Door Retry Control for Complete Coin Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coin handling apparatuses face challenges in reliably discharging all coins from storage due to the complexity of requiring a residual sensor for detecting remaining coins, which complicates the apparatus configuration.
Innovation Solution
A coin handling apparatus with a control unit that determines if all coins have been discharged based on recognition unit feedback, executing retry control to reopen the storage door if not all coins are recognized, and managing coin storage through a memory unit to track coin counts and adjust withdrawal operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vibration imparting mechanism and residual sensor are used to detect remaining coins, then coin discharge reliability is improved, but device complexity increases
Solution Approach 1:
The patent replaces the mechanical vibration imparting mechanism and residual sensor system with an intelligent control system that uses recognition unit data to determine discharge completeness. The control unit analyzes the relationship between stored coin count and recognized coin count to logically determine whether discharge is complete, eliminating the need for complex mechanical vibration mechanisms and residual sensors.
Solution Approach 2:
The patent implements a feedback mechanism where the recognition unit continuously monitors discharged coins and provides data to the control unit. The control unit uses this feedback information to determine whether all coins have been discharged and automatically executes retry control by reopening the door if discharge is incomplete, creating a closed-loop system that ensures complete discharge without additional hardware.
2Reliability
If the door is opened multiple times to ensure complete coin discharge, then coin discharge completeness is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary determination of discharge completeness by the control unit using recognition unit feedback before finalizing the discharge process. This allows the system to identify incomplete discharge early and execute retry control proactively, ensuring complete discharge without unnecessary repeated door openings and minimizing processing time.
Solution Approach 2:
The patent implements dynamic control where the control unit adjusts the door opening strategy based on real-time recognition data. The system dynamically determines whether to reopen the door for retry control based on the calculated discharge completeness, optimizing the balance between discharge completeness and processing time by avoiding unnecessary repeated operations.

AI summary
A coin handling apparatus includes a first storage that stores one or more coins, is equipped with a door, and configured to discharge the stored one or more coins by opening the door; a transport unit that transports the one or more coins discharged; a recognition unit that recognizes the one or more coins transported; and a control unit that, in response to receiving a withdrawal instruction, executes control to open the door and, based on a recognition result, to control the transport unit to transport one or more withdrawal target coins to a withdrawal unit, the one or more withdrawal target coins being among the one or more coins discharged from the first storage. When the control unit determines in the control that not all of the one or more coins have been discharged from the first storage, the control unit executes retry control to open the door again.
