Solution Overview

Problem

Existing beverage makers require users to manually pour a decalcifying agent into a permanently installed reservoir, which is time-consuming and poses a risk of injury due to heated parts, especially when descaling is needed.

Innovation Solution

A beverage maker with a reservoir integrated into the flow line system that can be easily exchanged via a quick-release mechanism, allowing for the use of powdered or tablet-form decalcifying agents like citric acid, and optionally includes a disinfectant, with a storage container designed as either disposable or reusable, featuring a detachable cover or refill opening for easy filling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the reservoir is permanently installed in the beverage maker, then the decalcifying agent can be continuously supplied to the flow line system, but the user must reach into the beverage maker to fill fresh decalcifying agent which is time-consuming and poses a risk of injury

Engineering Contradiction:
Improvecontinuous supply of decalcifying agentVSAvoidfilling of decalcifying agent
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The reservoir is divided into a removable storage container and a connection head that remains attached to the beverage maker. This segmentation allows the storage container to be easily removed and replaced without reaching into the device interior, while the connection head maintains continuous water supply to the flow line system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The storage container is extracted as a separate, removable component from the beverage maker. Users can remove the entire storage container to refill it externally, avoiding the need to reach into the heated interior of the beverage maker while maintaining continuous operation through quick replacement.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If liquid decalcifying agents are used, then they can be easily dispensed, but they may leak out if packaging is damaged and require complex approval procedures for cross-border exports

Engineering Contradiction:
Improvedispensing of decalcifying agentVSAvoidstorage and transport safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The decalcifying agent is changed from liquid to powdered or tablet form. This parameter change eliminates leakage risks associated with liquid packaging damage, simplifies export regulations, and maintains effectiveness through acid-forming properties when combined with water.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces water as an intermediary substance that converts the powdered or tablet decalcifying agent into its active liquid form during use. This mediator approach allows safe storage and transport of the agent in solid form while achieving the desired liquid decalcification effect during operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Duration of action of stationary object

If the reservoir is permanently installed, then the decalcification process can be maintained, but complex assembly steps or interventions in the interior of the beverage maker are required to replace the decalcifying agent

Engineering Contradiction:
Improvecontinuous decalcification processVSAvoidreplacement complexity
Core Design Contradiction:
Duration of action of stationary objectVSEase of manufacture

Solution Approach 1:

The reservoir system is segmented into a removable storage container and a fixed connection head. This allows the storage container to be easily replaced by simple removal and insertion operations without complex assembly steps or interior interventions, while the connection head maintains the continuous decalcification process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The storage container is designed with dynamic, removable connections to the connection head, allowing easy insertion and removal. This dynamic design enables quick replacement of the storage container without complex assembly operations while maintaining the continuous operation of the decalcification system through the permanently installed connection head.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables safe and efficient decalcification without direct user intervention, reducing the risk of injury and simplifying the decalcification process, while the powdered form of the decalcifying agent prevents leakage and is environmentally friendly, with a long service life due to low consumption.

Implementation Method 1

Various decalcifying agents are already known and in use which, due to a chemical reaction, are able to dissolve the 'calcification' in flow line systems and technical devices

Methodology Applied
Scientific EffectChemical reaction: Chemical Bonding

Implementation Method 2

the water flows from the water inflow to the mixture outlet through the dose of descaling agent introduced once by the user, dissolves it and is discharged as a mixture

Methodology Applied
Scientific EffectDissolution: Solvation
