Coin Processing Unit Width Reduction via Vertical Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coin processing units are large in width, hindering their introduction into small-scale financial institutions and are costly due to the need for a dispensing escrow unit and moving mechanisms, with the risk of abnormal coins being dispensed when mixed with normal coins.
Innovation Solution
A coin processing unit design where the wrapping unit is positioned in the lower region, allowing the coin storing and feeding unit and coin-roll storing and sending unit to be above it, eliminating the need for upward coin transport and incorporating a dispensing box with a vertically opening bottom plate that locks and unlocks to prevent abnormal coins from being dispensed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wrapping unit and coin storing and feeding unit are arranged side by side in the width direction, then coins can be transported from the coin storing and feeding unit to the wrapping unit, but the machine body becomes large in width direction
Solution Approach 1:
The patent changes the spatial arrangement from horizontal (width direction) to vertical (height direction). The coin storing and feeding unit is positioned above the wrapping unit, allowing coins to be transported downward via gravity rather than requiring horizontal transport mechanisms. This dimensional change eliminates the need for complex transport routes while reducing the machine's width.
2Adaptability or versatility
If a dispensing escrow unit and moving mechanisms are added for dispensing coins, then coin dispensing functionality is improved, but the machine body becomes large and costly
Solution Approach 1:
The patent makes the coin storing and feeding unit serve multiple functions: it not only stores and feeds coins to the wrapping unit but also functions as the dispensing escrow unit for coin dispensing operations. This eliminates the need for a separate dispensing escrow unit and its associated moving mechanisms, thereby reducing structural complexity while maintaining full dispensing functionality.
Solution Approach 2:
The patent merges the dispensing escrow unit function with the coin storing and feeding unit. By combining these two functions into a single unit, the patent eliminates redundant structures and moving mechanisms, resulting in a more compact and cost-effective machine design.
3Ease of operation
If the dispensing box bottom plate is always open for collection, then coin collection is simplified, but abnormal coins cannot be prevented from being dispensed
Solution Approach 1:
The patent makes the dispensing box bottom plate dynamic rather than static. The bottom plate can be opened or closed based on the operation mode: it remains closed during coin dispensing to prevent abnormal coins from being dispensed, and is opened during coin collection to simplify the collection process. This dynamic control mechanism resolves the contradiction between operational simplicity and reliability.
Solution Approach 2:
The patent implements feedback control through the control unit that monitors the operation mode and automatically adjusts the bottom plate state. During dispensing operations, the system detects the mode and keeps the bottom plate closed; during collection operations, it opens the bottom plate. This feedback mechanism ensures that abnormal coins are prevented from being dispensed while maintaining ease of collection.

AI summary
A wrapping unit for wrapping and forming a predetermined number of stacked coins into a coin-roll is arranged in a lower region of a machine body. A coin storing and feeding unit and sending unit are arranged side by side in a width direction of the machine body above the wrapping unit. Thus, the machine body is downsized in its width direction.In a state where a dispensing box attached to a dispensing box attachment unit is locked, coins are fed from the coin storing and feeding units, and the fed coins are recognized by a dispensing recognition unit, and sent to the dispensing box. If coins for dispensing sent to the dispensing box are normal coins, the dispensing box is unlocked. If an abnormal coin is recognized, a bottom plate of the dispensing box is opened. Coins dropping from the dispensing box are collected in a collection unit.
