Solution Overview

Problem

The combination of an ejection mechanism and barcode reader in beverage preparation machines can lead to cleanliness issues and inconsistent operation due to soiling of the barcode reader.

Innovation Solution

A delivery head design with a barcode reader window positioned to the front and an ejection chute to the rear, where the inlet, outlet, and barcode reader are aligned in a straight line, preventing the open inlet and outlet of the cartridge from passing over or near the barcode reader during ejection, thus maintaining cleanliness and consistency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If an ejection mechanism and barcode reader are combined in the delivery head, then the machine can automatically eject cartridges and read barcodes for identification, but the barcode reader window becomes prone to soiling from the open inlet and outlet during ejection, leading to inconsistent operation

Engineering Contradiction:
Improveautomatic cartridge ejection and barcode readingVSAvoidconsistency of barcode reader operation
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The patent positions the barcode reader window, inlet, and outlet in a linear arrangement along the longitudinal axis of the delivery head. This spatial configuration ensures that during cartridge ejection, the open inlet and outlet remain aligned with the longitudinal axis while the barcode reader window is positioned such that the cartridge components do not pass over or near it, preventing soiling while maintaining automated operation

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

Solution Approach 2:

The patent creates a localized clean zone around the barcode reader window by strategically positioning it relative to the inlet and outlet. The linear arrangement ensures that only specific areas (the inlet and outlet) are exposed to potential contamination during ejection, while the barcode reader window remains in a protected position that does not intersect with the ejection path of cartridge components

Inventive Principle:
Principle #3Local quality

2Ease of operation

If the inlet and outlet are positioned to allow free ejection of cartridges, then the ejection mechanism functions properly, but the open inlet and outlet pass over or near the barcode reader window during ejection, causing soiling

Engineering Contradiction:
Improvecartridge ejection functionVSAvoidsoiling of barcode reader window
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent resolves the conflict between ejection functionality and barcode reader cleanliness by arranging the inlet, outlet, and barcode reader window in a linear configuration along the longitudinal axis. This positioning ensures that during ejection, the cartridge components move along the axis without intersecting the barcode reader window's location, preventing soiling while maintaining proper ejection function

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

Solution Approach 2:

The linear arrangement of components creates a spatial intermediary zone where the barcode reader window is positioned between the inlet and outlet along the longitudinal axis. This configuration acts as a mediator that separates the ejection path from the barcode reading area, allowing both functions to coexist without interference or contamination

Inventive Principle:
Principle #24Intermediary (Mediator)
