Manual In-Cup Milk Frothing Pump for Moisture-Robust Control

Solution Overview

Problem

Existing milk frothing appliances are costly to manufacture, prone to moist-induced defects, and require extensive cleaning and external controls, which can be aesthetically unpleasing and user-unfriendly.

Innovation Solution

A milk frothing device utilizing a mechanical hand pump instead of an electric pump, with a simplified design that includes a hand pump actuator as the primary user control, eliminating the need for external controls and reducing electronic components, thus enhancing reliability and ease of cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If electric pumps and electronic components are used in milk frothing devices, then automation and functionality are improved, but manufacturing cost increases and reliability decreases due to moist-induced defects

Engineering Contradiction:

ImproveautomationVSAvoidreliability

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The patent replaces the electric pump with a manual pump mechanism operated by the user. This substitution eliminates the electronic components and motor required for automated milk delivery, thereby improving reliability by removing parts susceptible to moist-induced defects while maintaining the core functionality of milk frothing through manual operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The manual pump design uses simpler, less expensive mechanical components that are more resistant to moisture and easier to manufacture. While requiring manual operation, these components are more reliable in humid kitchen environments compared to electric pumps, effectively trading automation for robustness.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Extent of automation

3Adaptability or versatility

If multiple external controls are added to milk frothing devices, then functionality and user control are improved, but aesthetic appearance deteriorates and device complexity increases

Engineering Contradiction:

ImprovefunctionalityVSAvoidaesthetic appearance

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The patent integrates multiple functions into a single unified control mechanism. The main control serves both as the aesthetic focal point and as the operational interface for milk delivery and frothing functions, eliminating the need for separate external controls and maintaining a clean, minimalist design.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines control functions directly into the brewing chamber and cup holder assembly. The cup holder itself serves as a control interface, and the brewing chamber integrates both heating and frothing functions, eliminating the need for separate external controls and maintaining a clean, minimalist design.

Inventive Principle:

Principle #5Merging (Combining)
