Solution Overview

Problem

Existing coin dispensing apparatuses require multiple driving motors for multiple denominations, leading to increased size, cost, and slow dispensing of coins, as well as difficulty in downsizing and maintenance.

Innovation Solution

A coin dispensing apparatus with a common driving device that rotates multiple coin dispensing units simultaneously, using a transmission device with bevel gears to synchronize the rotation of rotary disks, allowing for parallel dispensing of multiple denominations and reducing the need for individual motors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple driving motors are used for multiple coin dispensing units, then each unit can operate independently, but the apparatus size increases and fabrication cost increases

Engineering Contradiction:

Improveindependent operation capabilityVSAvoidapparatus size

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The patent combines multiple driving motors into a single common driving device that rotates a shared rotary disk. This rotary disk has multiple apertures positioned at different radial distances from the center, allowing different coin denominations to be dispensed simultaneously or independently from the same rotating structure, thereby reducing the number of motors and apparatus size.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The common driving device and shared rotary disk serve multiple functions by accommodating different coin denominations through strategically positioned apertures. The same rotating mechanism can dispense various coin types by controlling which apertures receive and release coins, eliminating the need for separate dedicated motors for each denomination.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If multiple driving motors are used for multiple coin dispensing units, then each unit can operate independently, but dispensing speed decreases

Engineering Contradiction:

Improveindependent operation capabilityVSAvoiddispensing speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent enables continuous dispensing operation by having the rotary disk rotate continuously and present different apertures at the dispensing position at different times. This allows the system to maintain constant operation without idle periods between dispensing different denominations, as the rotating disk naturally cycles through all aperture positions.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent pre-positions coins of different denominations in different apertures of the rotary disk before rotation begins. This preliminary arrangement allows the system to rapidly switch between denominations simply by rotating the disk to bring the appropriate aperture to the dispensing position, eliminating the need for coin repositioning during operation.

Inventive Principle:

Principle #10Preliminary action

4Area of stationary object

If a common driving device is used for multiple coin dispensing units, then apparatus size is reduced, but maintenance difficulty increases

Engineering Contradiction:

Improveapparatus sizeVSAvoidmaintenance difficulty

Core Design Contradiction:

Area of stationary objectVSEase of repair

Solution Approach 1:

The patent segments the rotary disk into multiple independent aperture positions, each capable of holding and dispensing coins independently. This modular aperture design allows individual apertures to be accessed, cleaned, or repaired without affecting the entire rotary disk or other apertures, facilitating easier maintenance of the common driving device.

Inventive Principle:

Principle #1Segmentation

5Area of stationary object

If a common driving device is used for multiple coin dispensing units, then downsizing is facilitated, but device complexity increases

Engineering Contradiction:

Improveapparatus sizeVSAvoidcontrol complexity

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The rotating disk automatically presents different apertures at the dispensing position through its rotation, eliminating the need for complex manual intervention or sophisticated control systems to switch between denominations. The system self-regulates the dispensing sequence based on the rotational position and aperture configuration.

Inventive Principle:

Principle #25Self-service

AI summary

A coin dispensing apparatus capable of dispensing coins of a plurality of denominations surely and more quickly and capable of being fabricated at a low cost is provided. A plurality of coin dispensing units each including a rotary disk having apertures for receiving coins supplied from a coin source are used in combination. Coins received in the apertures are moved along a carrying path. The coins are moved through a dispensing opening from the carrying path toward a coin outlet. A common driving device commonly rotate the disks of the units. A transmission device transmits a driving force of the driving device to the disks. A passage blocking member is formed in a dispensing opening and is selectively positioned at the non-blocking position or the blocking position while simultaneously rotating the disks of the coin dispensing units, thereby dispensing the coins using rotation of the disks based on a dispensing instruction.
