Solution Overview

Problem

Concentrated liquid containers face issues such as reduced shelf life due to acidic components, staining risks from dyes, and difficulty in assessing the amount of concentrated liquid dispensed, leading to inconsistent dispensing and potential splashing when mixed with other liquids.

Innovation Solution

A container design with separate compartments for each liquid, a common cap with dispensing channels, and an insert that allows simultaneous dispensing of both liquids through controlled pressure, ensuring only the needed amounts mix during use, reducing interaction and staining risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If concentrated liquids are used to decrease packaging size, then packaging volume is reduced, but shelf life decreases due to acidic components

Engineering Contradiction:

Improvepackaging volumeVSAvoidshelf life

Core Design Contradiction:

Volume of moving objectVSDuration of action of stationary object

Solution Approach 1:

The container is divided into separate compartments, with each compartment holding a different concentrated liquid component. This segmentation prevents harmful interactions between components (such as acidic substances degrading other ingredients), thereby extending shelf life while maintaining the space-efficient concentrated format.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If concentrated liquid is dispensed through squeezing, then dispensing is achieved, but uncontrolled splashing and staining occur

Engineering Contradiction:

Improvedispensing operationVSAvoidstaining and splashing

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A mixing chamber serves as an intermediary space between the concentrated liquid compartment and the final dispensing point. The concentrated liquid is first released into this controlled chamber, diluted with water or another liquid, and then dispensed. This intermediary step prevents direct high-pressure spraying and uncontrolled splashing, reducing staining hazards while maintaining ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If all liquids are mixed at first use, then dispensing is simplified, but the mixed liquids cannot be consumed over time

Engineering Contradiction:

Improvedispensing mechanismVSAvoidconsumption duration

Core Design Contradiction:

Device complexityVSDuration of action of stationary object

Solution Approach 1:

The container employs a dynamic dispensing system where the mixing process is controlled and adjustable. Users can choose to mix all components at once or dispense partially mixed beverages over time. The system adapts to different consumption preferences, allowing both immediate consumption and extended use, while maintaining relatively simple device structure.

Inventive Principle:

Principle #15Dynamics

4Shape

If concentrated liquid with dye is dispensed, then desired coloring is achieved, but staining of surfaces occurs

Engineering Contradiction:

ImprovecoloringVSAvoidstaining

Core Design Contradiction:

ShapeVSObject-generated harmful factors

Solution Approach 1:

The mixing chamber acts as an intermediary that dilutes the concentrated dyed liquid before it reaches the dispensing point. By introducing water or another clear liquid into the mixing chamber first, the dye concentration is reduced, achieving the desired coloring effect while minimizing the staining potential of the dispensed beverage.

Inventive Principle:

Principle #24Intermediary (Mediator)

5Ease of operation

If the same squeeze force is used repeatedly, then operation is consistent, but dispensing amount changes as liquid level reduces

Engineering Contradiction:

Improvesqueeze operation consistencyVSAvoiddispensing precision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The container replaces the direct mechanical squeeze-dispense system with a pressure-driven flow system. Squeezing the container creates pressure that forces the concentrated liquid through a controlled opening or valve into the mixing chamber. This pressure-driven mechanism provides more consistent and predictable dispensing amounts compared to direct mechanical squeezing, as the flow rate is better controlled by the pressure differential and opening geometry rather than varying mechanical leverage.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The container effectively isolates and dispenses liquids separately until use, maintaining shelf life and preventing staining, while allowing precise mixing without the need for complex dispensing steps, ensuring consistent and controlled dispensing.

Implementation Method 1

The insert defines first and second flow paths, each having an upstream entrance in fluid communication with the first and second body access openings and a downstream exit in fluid communication with the first and second dispensing channels

AI summary

A container (100) for isolating first and second fluids, such as beverage concentrate components, until dispensing is provided, as well as methods of assembly and dispensing. The container can have first (111) and second (113) enclosed bodies for containing the first and second fluids to be dispensed and an insert (130) directing fluid from the enclosed bodies, such as toward one or more valves or separate discharge paths (148a, 148b).
