Solution Overview

Problem

Existing dispensing systems are limited by having only one inlet source, requiring excessive manual changes, collapsing due to vacuum, and risking contamination, with none utilizing Venturi-based fluid dispensing from multi-inlet tubing.

Innovation Solution

A system featuring a multiple tubing arrangement with Venturi devices that allows fluid to be drawn from multiple reservoirs at equal rates using a vacuum, eliminating the need for container vacuum and preventing contamination through a continuous loop.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single inlet source is used in the dispensing system, then the system structure is simple, but excessive manual changeovers are required during operation

Engineering Contradiction:
Improvemanual changeover frequencyVSAvoidnumber of inlet sources
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system divides the fluid supply into multiple independent inlet sources (primary inlet tube with primary reservoir, auxiliary inlet tube with auxiliary reservoir) that can operate simultaneously or independently, eliminating the need for manual changeovers between single sources

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dispensing system is designed to handle multiple types of fluids from different reservoirs (e.g., water, milk, syrup) through a universal dispensing mechanism, allowing any inlet source to replace another without system reconfiguration

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

2Productivity

If vacuum is applied to draw fluid from a single reservoir, then fluid delivery is achieved, but the bottle collapses due to vacuum

Engineering Contradiction:
Improvefluid delivery rateVSAvoidreservoir structural integrity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The system segments the vacuum application across multiple reservoirs rather than applying full vacuum to one reservoir, distributing the pressure differential and preventing any single reservoir from collapsing

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the pressure parameters by applying vacuum proportionally to multiple reservoirs simultaneously, maintaining pressure balance that prevents structural collapse while achieving fluid delivery

Inventive Principle:
Principle #35Parameter changes

3Productivity

If manual changeovers are required between inlet sources, then system simplicity is maintained, but time loss occurs during peak business hours

Engineering Contradiction:
Improveoperational continuityVSAvoidchangeover time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system maintains continuous fluid dispensing operation by having multiple inlet sources available simultaneously, eliminating interruptions and changeover downtime during peak operational periods

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system prepares multiple reservoirs in advance and keeps them connected to the dispensing system, so when one reservoir is depleted, another is already ready to take over without interruption

Inventive Principle:
Principle #10Preliminary action

4Reliability

If a single inlet tube system is used, then the tubing arrangement is simple, but contamination risk increases

Engineering Contradiction:
Improvefluid system cleanlinessVSAvoidtubing arrangement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The tubing system is segmented into separate inlet tubes for different fluid sources, with each tube dedicated to a specific reservoir, preventing cross-contamination while maintaining manageable system complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces intermediate components (check valves, flow control devices) in the tubing arrangement that prevent backflow and contamination between different fluid sources while maintaining relatively simple overall structure

Inventive Principle:
Principle #24Intermediary (Mediator)

Function Achieved in This Case

Enables multiple inlet sources, reduces changeover time, maintains continuous vacuum, and ensures equal distribution of fluid, preventing cross-contamination.

Implementation Method 1

The multiple tubing arrangement being responsive to a vacuum provided from the dispenser, for drawing the fluid from the multiple reservoirs so as to deplete the multiple reservoirs at relatively equal amounts based on the Venturi effect

Methodology Applied
Scientific EffectVenturi effect: Venturi Effect

Implementation Method 2

The primary inlet tube may include a Venturi device having inlet and outlet ports for respectively receiving an auxiliary feed and providing a primary feed, as well as tubing for inserting into the primary reservoir, and may be configured to couple to the auxiliary inlet tube so as to provide a proportional vacuum and siphoning effect

AI summary

The present invention provides a system featuring a dispenser for providing fluid from multiple reservoirs to an appliance or other suitable device; and a multiple tubing arrangement coupled between the dispenser and the multiple reservoirs of fluid, the multiple tubing arrangement being responsive to a vacuum provided from the dispenser, for drawing the fluid from the multiple reservoirs so as to deplete the multiple reservoirs at relatively equal amounts based on the Venturi effect. The multiple tubing arrangement comprises a primary inlet tube for arranging in a primary reservoir, an auxiliary inlet tube for arranging in an auxiliary reservoir, and a feed connector tube arranged between the primary inlet tube and auxiliary inlet tube. The primary inlet tube is coupled to the auxiliary inlet tube so as to provide a proportional vacuum and siphoning effect. The multiple tubing arrangement siphons and depletes the fluid from the primary reservoir and the auxiliary reservoir based on the Venturi effect.
