Solution Overview

Problem

Existing removal systems for liquids from bottles suffer from vapor leakage, contamination, and user exposure due to loose seals and residue transfer, and are not suitable for smaller containers without significant structural changes.

Innovation Solution

A removal system with a hermetically sealed extraction head and detachable hoses, featuring a mechanical actuating mechanism for secure hose attachment and release, preventing vapor escape and contamination, and allowing for easy hose replacement to maintain cleanliness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple cover with a hose insertion hole is used, then the device complexity is low, but vapor leakage occurs and sealing is not tight

Engineering Contradiction:
Improvestructure simplicityVSAvoidvapor leakage
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent uses a flexible membrane that can be stretched over the bottle opening to create a vapor-tight seal, while still allowing the hose to pass through. This flexible film approach provides effective vapor barrier without requiring complex rigid sealing mechanisms.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent introduces a separate membrane component as an intermediary between the cover and the bottle opening. This membrane specifically addresses the vapor sealing function, allowing the rest of the cover structure to remain simple while achieving the sealing objective.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the hose is pulled out of the empty bottle, then the liquid can be removed from the bottle, but the tubing contaminates the liquid in the next bottle

Engineering Contradiction:
Improveliquid removal efficiencyVSAvoidcontamination
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent makes the hose disposable by providing multiple hoses that can be easily attached and detached. Each hose is used for one bottle and then discarded, preventing cross-contamination between bottles. The low cost of the hoses makes this single-use approach economically viable.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent segments the hose into individual disposable units rather than using a single reusable hose. This segmentation allows each hose to be dedicated to one bottle, eliminating the contamination pathway that exists when one hose serves multiple bottles.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the user pulls the tube out of the bottle, then the liquid can be accessed, but the user is exposed to the adhering liquid

Engineering Contradiction:
Improvehose accessibilityVSAvoiduser exposure to liquid
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

By making the hose disposable, the system allows the hose to remain in the bottle throughout the entire liquid removal process. The user never needs to manually pull or handle the hose, eliminating direct contact with potentially hazardous liquid residues on the hose exterior.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Object-affected harmful factors

If a hermetically sealed extraction head is used, then vapor escape is prevented, but the device complexity increases

Engineering Contradiction:
Improvevapor containmentVSAvoidextraction head structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent uses a simple flexible membrane stretched over the extraction head opening to achieve hermetic sealing. This approach provides effective vapor containment without requiring complex mechanical sealing components, maintaining relative simplicity while achieving the vapor barrier function.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

The invention relates to a dispensing system (1) with a dispensing head (2) that can be placed on the opening of a bottle (3), wherein the dispensing head (2) has a closing means for closing the opening of the bottle (3). A hose (5) is mounted in the dispensing head (2) such that, when the dispensing head (2) is placed on the opening, the hose (5) projects into the bottle (3) and liquid (4) can be drawn from the bottle (3) via the hose (5). An actuating mechanism is provided by means of which the mounting of the hose (5) in the dispensing head (2) can be released.
