Air-Column Liquid Dispensing Structure for Precise Dosing

Solution Overview

Problem

Current flexible plastic packaging for liquid products lacks structural integrity, uniform product dispensing, and user-friendliness, leading to damage and inefficiencies in handling and transportation, while rigid plastic packaging is resource-intensive and costly.

Innovation Solution

A liquid dispensing device featuring an air column for stability, a casing formed by side walls, a bottom wall with a dispensing opening, and a cap with a hollow section for precise dosing, utilizing an upside-down positioning and cap design for controlled dispensing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If flexible plastic packaging is used, then plastic consumption and cost are reduced, but structural integrity and product protection are compromised

Engineering Contradiction:

Improveplastic consumptionVSAvoidstructural integrity

Core Design Contradiction:

Loss of substanceVSStrength

Solution Approach 1:

The packaging is divided into two functional parts: a flexible plastic body for material efficiency and a rigid insert structure for structural integrity. This segmentation allows each component to optimize its specific function while working together as a unified packaging system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The packaging combines flexible plastic material with a rigid insert structure to create a composite packaging system. This composite approach integrates the material efficiency of flexible plastic with the structural strength of rigid materials, resolving the contradiction between reducing plastic consumption and maintaining structural integrity.

Inventive Principle:

Principle #40Composite materials

2Strength

If rigid plastic packaging is used, then structural integrity and product protection are improved, but plastic consumption, weight, and cost increase

Engineering Contradiction:

Improvestructural integrityVSAvoidplastic consumption

Core Design Contradiction:

StrengthVSLoss of substance

Solution Approach 1:

The packaging is divided into two functional parts: a flexible plastic body for material efficiency and a rigid insert structure for structural integrity. This segmentation allows each component to optimize its specific function while working together as a unified packaging system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Rigid structural properties are applied locally only where needed for protection and structural integrity, rather than throughout the entire packaging. The rigid insert is positioned specifically to provide support and protection, while the rest of the packaging remains flexible and material-efficient.

Inventive Principle:

Principle #3Local quality

3Strength

If rigid plastic packaging is used, then product protection against impact and breakage is improved, but ease of handling and user-friendliness are reduced

Engineering Contradiction:

Improveproduct protectionVSAvoidease of handling

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The packaging is divided into two functional parts: a flexible plastic body for material efficiency and a rigid insert structure for structural integrity. This segmentation allows each component to optimize its specific function while working together as a unified packaging system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The packaging uses a flexible plastic body that can be easily manipulated and handled, while incorporating a rigid insert structure that provides protection. The flexible outer shell allows for easy handling and user-friendliness, while the rigid insert ensures product protection against impact and breakage.

Inventive Principle:

Principle #30Flexible shells and thin films
