Solution Overview

Problem

Existing beverage preparation machines lack easy and tool-free access to operational components, making maintenance and cleaning challenging for both technicians and users, particularly for flow pressurization and milk frothing devices.

Innovation Solution

The machine design includes side and posterior access elements that allow technicians to assemble and disassemble flow pressurization devices without disassembling the casing, and provides tool-free access to milk frothing devices and discharge casings, using retention elements and actuation parts for easy handling and retention without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the machine casing is designed with traditional sealed structure, then the internal components are protected from damage, but access to flow pressurization devices requires complete disassembly of the casing

Engineering Contradiction:

ImproveAccess to flow pressurization devicesVSAvoidCasing structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The machine casing is divided into multiple access elements: a first access element for flow pressurization devices and a second access element for control means. This segmentation allows technicians to access specific components without disassembling the entire casing, resolving the contradiction between ease of access and structural integrity.

Inventive Principle:

Principle #1Segmentation

2Ease of repair

If access to internal components is simplified, then maintenance and cleaning become easier, but sensitive components may be exposed to accidental damage

Engineering Contradiction:

ImproveMaintenance of flow pressurization devicesVSAvoidRisk of damage to sensitive components

Core Design Contradiction:

Ease of repairVSObject-affected harmful factors

Solution Approach 1:

By creating separate access elements for different component groups (flow pressurization devices vs. control means), the design enables targeted maintenance while preventing unauthorized or accidental access to sensitive control components, thus balancing ease of repair with protection from damage.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If milk frothing device is made removable for cleaning, then cleaning accessibility is improved, but the device structure becomes more complex with additional retention elements

Engineering Contradiction:

ImproveCleaning of milk frothing deviceVSAvoidRetention mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The milk frothing device incorporates dynamic retention elements that can be actuated to release the device from its mounted position. This allows the device to transition between fixed and removable states, enabling easy cleaning while maintaining a relatively simple overall structure through controlled mobility rather than complex permanent fixtures.
