Solution Overview

Problem

Existing beverage vending machines are bulky and costly due to the need for multiple storage containers for cleaning and descaling agents, which are often designed as disposable items or require pumps, leading to high production and acquisition costs and environmental waste.

Innovation Solution

A compact beverage vending machine design with a single receiving space for interchangeable reservoirs, where the electronic control device automatically selects the appropriate cleaning or descaling program based on the inserted container, and the flow line system is flushed with fresh water to prevent residue buildup, allowing for flexible adaptation to user needs and regional water hardness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple storage containers for cleaning and descaling agents are provided, then the beverage vending machine can perform comprehensive maintenance functions, but the machine becomes bulky and complex

Engineering Contradiction:
Improvemaintenance functionVSAvoidmachine structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single storage container is designed to hold multiple different maintenance agents (cleaning agent, descaling agent, and rinse agent) through interchangeable cartridges or compartments. The electronic control device automatically identifies the inserted cartridge type and selects the appropriate maintenance program, allowing one physical container to serve multiple maintenance functions that previously required separate containers.

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

Solution Approach 2:

The patent combines multiple storage containers into a single integrated storage container structure. Instead of providing separate physical containers for cleaning agent, descaling agent, and rinse agent, the invention merges them into one container that can hold different agent types, reducing the overall number of components and simplifying the machine structure.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If disposable storage containers with pumps are used, then cleaning and descaling agents can be automatically delivered, but production and acquisition costs increase

Engineering Contradiction:
Improveautomatic deliveryVSAvoidproduction cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The pump mechanism is extracted from the storage container and relocated to the beverage vending machine's main body. Instead of incorporating expensive pumps into disposable containers, the invention uses the machine's existing pump system to deliver maintenance agents from simple, pump-free storage containers, significantly reducing production costs while maintaining automatic delivery capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The storage containers are designed to work passively with the machine's existing fluid delivery system. The containers simply store the maintenance agents, and the machine's pump and control systems handle all active delivery functions, allowing the containers to be simple, low-cost components that rely on the machine's infrastructure for automated operation.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If disposable storage containers are used, then ease of use is improved, but environmental waste increases

Engineering Contradiction:
Improveease of useVSAvoidwaste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

Instead of discarding entire disposable storage containers after use, the invention enables recovery and reuse of the container structure. The same physical container can be emptied, refilled with different maintenance agents, and reinserted into the machine multiple times, transforming a single-use component into a reusable vessel that reduces waste while maintaining ease of operation.

Inventive Principle:
Principle #34Discarding and recovering

4Device complexity

If a single storage container is used, then the machine becomes compact and cost-effective, but the ability to store multiple agents simultaneously is reduced

Engineering Contradiction:
Improvemachine compactnessVSAvoidagent storage capacity
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The storage container is designed with dynamic, reconfigurable internal structure. Instead of fixed compartments for different agents, the container can be configured to hold different types of maintenance agents in different arrangements. The electronic control device dynamically selects which agent to use based on the inserted cartridge type and the selected maintenance program, allowing a single physical container to provide the storage capacity of multiple fixed containers.

Inventive Principle:
Principle #15Dynamics
