Solution Overview

Problem

Existing machines for preparing infused beverages using disposable capsules or pods are complex, bulky, costly due to solenoid valves, prone to encrustations, and limited to delivering one beverage at a time, lacking the ability for simultaneous delivery of hot water and infused beverage.

Innovation Solution

A machine design with separate delivery ducts for infused beverage and hot water, featuring a valve member that allows simultaneous or independent delivery of both, controlled by a manually operable lever, reducing complexity and size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If solenoid valves are used to control hot water delivery, then the machine can deliver hot water independently, but the machine becomes bulky and costly

Engineering Contradiction:
Improvehot water delivery capabilityVSAvoidmachine size and cost
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent removes the solenoid valve from the system entirely. Instead of using an electrically controlled solenoid valve, the invention uses a mechanically operated plug valve that is manually controlled. This extraction of the complex solenoid valve component directly reduces machine complexity, size, and cost while maintaining the capability to control hot water delivery independently through the manual valve mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the expensive, complex solenoid valve with a simple, inexpensive manual plug valve mechanism. The manual valve is a basic mechanical component that is much cheaper and simpler to manufacture than an electrically actuated solenoid valve, thereby reducing overall machine cost and complexity while achieving the same functional outcome of controlling hot water flow.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Ease of operation

If solenoid valves are used for beverage delivery control, then precise flow control is achieved, but encrustations occur on the valves

Engineering Contradiction:
Improveflow control precisionVSAvoidencrustations on valve
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the solenoid valve component that is prone to encrustations and replaces it with a manual plug valve system. The manual valve design allows for easier cleaning and maintenance, reducing the harmful encrustation problem while maintaining adequate flow control capability for the beverage delivery application.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The manual plug valve design enables the user to directly control and adjust the flow manually, and the simple mechanical structure allows for easy self-cleaning and maintenance. This self-service capability reduces the accumulation of encrustations that would otherwise require complex automated cleaning systems or specialized valve designs.

Inventive Principle:
Principle #25Self-service
