Solution Overview

Problem

Existing post-mix beverage dispensing equipment cannot produce both hot and cold drinks, limiting the variety of beverages that can be dispensed.

Innovation Solution

A beverage dispenser system that includes a temperature selector switch, solenoid valves, and mixing chambers to control the flow of hot and cold water with beverage concentrate, allowing for the creation of both hot and cold versions of a beverage using the same concentrate, with adjustable water-to-concentrate ratios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing post-mix beverage dispensing equipment is used, then cold beverages can be produced, but hot beverages cannot be produced

Engineering Contradiction:
Improvebeverage temperature varietyVSAvoidequipment configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The beverage dispenser is designed to perform multiple functions by incorporating both hot and cold water supply systems, allowing the same device to produce both hot and cold beverages. The system uses a single dispenser unit with selectable temperature modes, eliminating the need for separate hot and cold beverage machines.

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

Solution Approach 2:

The system dynamically switches between hot and cold water supply based on user selection. The control mechanism activates different solenoid valves depending on whether hot or cold beverage preparation is selected, enabling the system to adapt its function in real-time without physical reconfiguration.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If separate hot and cold beverage dispensers are used, then both hot and cold beverages can be produced, but equipment cost and space increase

Engineering Contradiction:
Improvebeverage temperature varietyVSAvoidequipment space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines hot and cold beverage dispensing functions into a single integrated unit. The dispenser merges the water supply system, mixing chamber, and dispensing mechanism into one compact device, reducing the space required compared to having separate hot and cold beverage machines.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If separate hot and cold beverage dispensers are used, then both hot and cold beverages can be produced, but equipment cost increases

Engineering Contradiction:
Improvebeverage temperature varietyVSAvoidequipment cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The beverage dispenser is designed to perform multiple functions by incorporating both hot and cold water supply systems, allowing the same device to produce both hot and cold beverages. The system uses a single dispenser unit with selectable temperature modes, eliminating the need for separate hot and cold beverage machines.

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

AI summary

An apparatus ( 100 ) and method may be configured for detecting selection between a hot version and a cold version of a beverage, causing opening of a first of a plurality of valves ( 212, 214 ) and closing of a second of the plurality of valves ( 234, 236 ) for providing water to a first of a plurality of mixing chambers ( 220, 238 ) on the selection, causing delivery of beverage concentrate to the first mixing chamber, controlling a flow rate of the water and a flow rate of the beverage concentrate into the mixing chamber for mixing of the water with the beverage concentrate in a controlled ratio to create the beverage, and dispensing the beverage from the mixing chamber.
