Solution Overview

Problem

Conventional coin handling machines are inadequate for retail stores as they cannot efficiently handle large amounts of coins, are prone to coin jams, and are costly and complex, making them unsuitable for retail environments.

Innovation Solution

A coin handling machine with a simplified transportation structure, using a rotary disk inclined at an angle and a hopper to feed coins one by one, along with a replenishing and collecting unit that includes an overflow stacking unit and a coin cassette for efficient coin management and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If conventional coin handling machines are used, then they can handle coins, but they cannot efficiently handle large amounts of coins and are prone to coin jams

Engineering Contradiction:
Improveamount of coinsVSAvoidcoin jam occurrence
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The machine divides coin storage into multiple denomination-specific escrow units and storing and feeding units, each handling specific coin types separately. This segmentation prevents different coin types from interfering with each other and reduces overall coin jam occurrence while enabling large-volume processing

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs a rotary disk mechanism that dynamically feeds coins one by one from storage to the transport path. This dynamic feeding system adapts to varying coin volumes and types, preventing jams by controlling the feeding rhythm while maintaining high processing capacity

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If bank-grade coin depositing and dispensing machines are used, then large amounts of coins can be handled, but the machines are large in size, expensive, and have complicated transport paths

Engineering Contradiction:
Improveamount of coinsVSAvoidtransport path complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The rotary disk mechanism serves multiple functions: storage, sorting by denomination, and feeding to the transport path. This multi-functionality eliminates the need for separate complex transport paths for each operation, simplifying the overall system while maintaining large coin handling capacity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent nests multiple functional components within compact spaces - escrow units are positioned within the housing, storing and feeding units are integrated into the structure, and the rotary disk is nested within the coin path. This nesting achieves large coin volume handling in a compact footprint with simplified pathways

Inventive Principle:
Principle #7Nested doll (Nesting)

3Quantity of substance

If cylinder-based coin storage is used, then coins can be stored, but coins easily stand up in the cylinder and cause trouble such as coin jams

Engineering Contradiction:
Improvecoin storage capacityVSAvoidcoin jam occurrence
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

Instead of storing coins upright in cylinders where they can stand and jam, the patent inverts the approach by using a rotary disk that feeds coins horizontally one by one. The coins remain flat and aligned during storage and feeding, eliminating the standing problem while maintaining storage capacity

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent replaces the passive cylinder storage system with an active rotary disk feeding mechanism. This substitution transforms the coin handling from gravity-dependent vertical storage to mechanically-controlled horizontal feeding, preventing coins from standing and causing jams while maintaining efficient storage and dispensing

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
