Solution Overview

Problem

Traditional milk containers for coffee machines lack versatile adjustment mechanisms, limiting the ability to dispense milk into cups of varying heights and preventing simultaneous dispensing into multiple cups, which reduces coffee machine productivity.

Innovation Solution

A milk container with a flexible pipe connection allows the milk dispenser to be adjustable in height and position, enabling simultaneous dispensing into multiple cups by hooking to an external coffee dispenser, with the flexibility of the pipe allowing adaptation to different cup heights and minimizing overall dimensions for storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a complex movement mechanism is used to adjust the milk dispenser position, then the position can be adjusted, but the structure becomes complex and versatility is still insufficient for different cup heights

Engineering Contradiction:
Improveadaptability to different cup heightsVSAvoidcomplexity of movement mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces fixed adjustment mechanisms with a dynamic flexible pipe connection that allows the milk dispenser to move freely in space. The flexible pipe enables continuous position adjustment rather than discrete steps, providing adaptability to various cup heights without complex mechanical structures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the physical state of the connection from rigid to flexible, allowing the milk dispenser to achieve multiple positions through the flexibility of the pipe rather than through complex mechanical adjustment mechanisms. This parameter change enables versatile positioning while simplifying the overall structure.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the milk dispenser is fixed in position, then the structure is simple, but it cannot adapt to different cup heights or dispense into multiple cups simultaneously

Engineering Contradiction:
Improveability to dispense into multiple cups simultaneouslyVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The flexible pipe connection enables the milk dispenser to serve multiple functions: it can dispense into single or multiple cups simultaneously, adapt to different cup heights, and maintain a compact configuration when not in use. This single flexible connection provides multi-functionality without requiring multiple complex mechanisms.

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

Solution Approach 2:

The dynamic flexibility of the pipe allows the milk dispenser to be positioned for single or multiple cup dispensing as needed, enabling the system to adapt its configuration for different productivity requirements without structural complexity.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the milk dispenser is positioned remotely from the containment body, then it can reach different cup positions, but the overall dimensions increase

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidoverall dimensions
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent uses a flexible pipe to connect the milk dispenser to the containment body, allowing the dispenser to extend to remote positions when needed while maintaining a compact overall configuration. The flexible pipe acts as a space-efficient connection that does not increase the permanent dimensions of the system.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The dynamic positioning capability provided by the flexible pipe allows the milk dispenser to extend remotely during operation but return to a compact configuration during storage, effectively managing the volume requirement while maintaining positioning flexibility.

Inventive Principle:
Principle #15Dynamics
