Solution Overview

Problem

Modern coffee machines often have cup pedestals that are not adjustable in height, limiting the use of taller latte macchiato glasses and causing splashing when using shorter espresso cups due to a fixed dispensing point, which requires complex design and hose routing adjustments.

Innovation Solution

A non-rotatable and height-adjustable plunger for the beverage container storage device, featuring a spiral link and lever system that allows easy height adjustment without twisting, enabling the use of containers of varying heights without splashing, and simplifying the design and hose routing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cup pedestal height is fixed, then the structure is simple, but taller latte macchiato glasses cannot be used and shorter espresso cups cause splashing

Engineering Contradiction:
Improvecompatibility with different container heightsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cup pedestal is made height-adjustable through a spiral link mechanism that converts rotational movement of a lever into vertical displacement. This dynamic adjustment allows the pedestal to adapt to different container heights while maintaining structural simplicity through the use of a compact mechanical linkage system integrated into the housing.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the dispensing point height is made variable, then containers of different heights can be used, but the design effort and hose routing complexity increase considerably

Engineering Contradiction:
Improveadjustability to different container heightsVSAvoiddesign complexity and hose routing
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The dispensing point is integrated with the height-adjustable cup pedestal, moving vertically together with it. This dynamic coupling allows the dispensing point to automatically adapt to different container heights without requiring separate adjustment mechanisms or complex hose routing, as the hose connection point moves with the pedestal.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cup pedestal and dispensing point are combined into a single integrated assembly that moves together. This merging eliminates the need for separate adjustment mechanisms for the dispensing point, simplifying the overall design and hose routing while maintaining adaptability to different container heights.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If a rotatable plunger is used for height adjustment, then the mechanism can be simple, but the container may be twisted which is undesirable for containers with handles

Engineering Contradiction:
Improveease of height adjustmentVSAvoidtwisting of the container
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The plunger is designed to move only vertically through a guide mechanism that constrains its motion to a linear path. This dynamic constraint prevents rotational movement while maintaining ease of operation through the spiral link lever mechanism, ensuring that containers are adjusted in height without being twisted.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If the plunger height is adjustable, then different container sizes can be accommodated, but the mechanism becomes more complex

Engineering Contradiction:
Improveaccommodation of different container sizesVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The height adjustment mechanism uses a spiral link connected to a lever that converts rotational movement into vertical displacement of the plunger. This dynamic mechanism provides smooth, continuous height adjustment while maintaining relative simplicity through the use of a compact mechanical linkage integrated into the housing structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spiral link mechanism serves multiple functions: it provides height adjustment, acts as a locking mechanism through its self-locking spiral geometry, and integrates into the housing structure as a space-efficient design. This multi-functionality reduces overall mechanism complexity while achieving the desired adaptability.

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