Solution Overview

Problem

Existing vending machine storage and dispensing technologies, such as spirals and sliders, are limited in accommodating various product sizes and shapes, making it difficult to change products seasonally or when offering different items, as they often require costly conversions or are not technically feasible for products like canned goods or unusual shapes.

Innovation Solution

A coupling system with rotatable rollers and a coupling device that allows for mechanical synchronization of transport devices, enabling easy adjustment and synchronization of conveying speed, accommodating products of varying dimensions and shapes by creating a releasable positive connection between adjacent rollers, allowing for flexible and customizable storage and dispensing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional spirals or sliders are used for conveying goods, then the structure is simple and reliable, but the adaptability to different product sizes and shapes is limited

Engineering Contradiction:
Improveadaptability to different product sizes and shapesVSAvoidcomplexity of transport device configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transport system is divided into multiple independent transport devices, each with its own rotatable roller and drive mechanism. These segmented units can be independently configured and combined to handle different product types, allowing the system to adapt to various product sizes and shapes without requiring complete system replacement

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transport devices incorporate rotatable rollers that can rotate at variable speeds and can be mechanically synchronized through coupling devices. This dynamic capability allows the system to adjust its operation to match different product characteristics and conveying requirements, enhancing adaptability while maintaining coordinated operation

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the vending machine is converted to accommodate different products, then product versatility is improved, but the conversion cost and complexity increase significantly

Engineering Contradiction:
Improveproduct versatilityVSAvoidconversion cost and ease of implementation
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The transport devices are designed as universal, modular units that can handle multiple product types through standardized interfaces and adjustable parameters. The coupling system allows different transport devices to be combined in various configurations, enabling a single standardized design to serve multiple product categories without costly custom conversions

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

Solution Approach 2:

The system achieves product versatility by changing operational parameters such as roller rotation speed, coupling configuration, and transport device arrangement rather than physically modifying the structure. This allows the same hardware to adapt to different products by adjusting speed ratios and mechanical connections, avoiding expensive conversions

Inventive Principle:
Principle #35Parameter changes

3Productivity

If multiple transport devices are used to handle various products, then product capacity is improved, but the synchronization of conveying speed becomes difficult

Engineering Contradiction:
Improveproduct handling capacityVSAvoidsynchronization mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Multiple transport devices are mechanically merged through the coupling system, which connects adjacent rotatable rollers through a common coupling device. This merging creates a synchronized mechanical linkage where the rotation of one roller is directly coupled to others, ensuring coordinated conveying speed across multiple devices while maintaining their individual capacity to handle different products

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If fixed-speed transport devices are used, then the device structure is simple, but the ability to adjust conveying speed for different products is limited

Engineering Contradiction:
Improveconveying speed adjustabilityVSAvoidspeed control mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transport devices transition from fixed-speed operation to dynamic speed control through independently drivable rotatable rollers. Each roller can be driven at variable speeds and mechanically synchronized through coupling devices, allowing the system to adapt conveying speeds to different product requirements while maintaining coordinated operation through mechanical linkage

Inventive Principle:
Principle #15Dynamics
