Solution Overview

Problem

Traditional coffee machines require manual removal of coffee packages after each use, leading to inconvenience and complex, voluminous mechanisms for automatic package removal.

Innovation Solution

A coffee machine with a simple structure and small volume, featuring a first mechanism with a horizontal arc-shaped recess and a second mechanism with a vertical arc-shaped recess, along with a torsion spring and gear portion, allowing for automatic package removal without additional auxiliary components, ensuring reliable sealing and efficient extraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a complex automatic package removal mechanism is added to the coffee machine, then the package removal automation is improved, but the device complexity and housing volume increase

Engineering Contradiction:
Improvepackage removal automationVSAvoidmechanism complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent merges the package delivery function and package removal function into a single integrated mechanism. The first arc-shaped recess serves both to deliver the package from the inlet and to remove it from the chamber by combining both functions in one structural element, thereby reducing overall mechanism complexity while maintaining automation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The first mechanism with the arc-shaped recess performs multiple functions: it delivers the coffee package into the chamber, seals the package during brewing, and removes the package after brewing. This multi-functional design eliminates the need for separate dedicated mechanisms for each operation, reducing device complexity while achieving full automation.

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

2Extent of automation

If a complex automatic package removal mechanism is added to the coffee machine, then the package removal automation is improved, but the housing volume increases

Engineering Contradiction:
Improvepackage removal automationVSAvoidhousing volume
Core Design Contradiction:
Extent of automationVSVolume of stationary object

Solution Approach 1:

The patent merges the package delivery function and package removal function into a single integrated mechanism. The first arc-shaped recess serves both to deliver the package from the inlet and to remove it from the chamber by combining both functions in one structural element, thereby reducing overall mechanism complexity while maintaining automation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mechanism utilizes vertical movement and rotation in addition to horizontal movement. The first mechanism rotates about a vertical axis and the second mechanism rotates about a horizontal axis, creating a three-dimensional operation space that efficiently uses the available housing volume and reduces the overall footprint required for automatic package removal.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The patent application relates to a coffee machine convenient for package removing including a housing (1) having a package inlet (11) and a package outlet (12). The coffee machine further includes a first mechanism (2) constrained in the housing (1) and moveable along the horizontal direction of the housing (1), a second mechanism (3) rotatably set in the housing (1) and capable of rotating in a vertical plane, and a torsion spring (5). The lower portion of the first mechanism (2) has a first arc-shaped recess, and the open ends of the first arc-shaped recess (21) incline downwardly. The upper portion of the second mechanism has a second arc-shaped recess (31), and the open ends of the second arc-shaped recess (31) incline upwardly and opposite to the package inlet (11) for the coffee package (4) having a circular edge to be laid thereon. The torsion spring (5) acts on the second mechanism (3) to keep the open ends of the second arc-shaped recess (31) inclining upwardly. The coffee package (4) is automatically removed through the movement of the first mechanism (2) and rotation of the second mechanism (31). The package (4) can be successfully removed without additional auxiliary components for jointly clamping the package (4). The structure is simpler, and the volume thereof is greatly reduced.
