Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

High-viscosity liquids stored in hard containers with narrow openings tend to stick to the container walls, making it difficult to discharge remaining content efficiently, leading to overconsumption, environmental pollution, contamination, and recycling issues.

Innovation Solution

A content charging device and method that uses an elastic pouch within a hard container, where the pouch is extended and pressurized to push content towards the opening, allowing for effective discharge and maintaining container shape flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a pump is coupled to a discharge unit to discharge viscous liquid content, then convenience of use is improved, but remaining content sticks to the inner wall and cannot be effectively discharged

Engineering Contradiction:

Improveconvenience of useVSAvoidremaining content

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The discharge unit is designed to be movable relative to the container, allowing it to change position dynamically. The discharge unit includes a discharge pipe that can be moved to different locations, enabling effective discharge of remaining content from various positions within the container, thus preventing content from sticking to the inner wall.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of the discharge process by varying the position of the discharge pipe and using vibration mechanisms. The vibration unit generates vibrations that change the physical state of the remaining content, reducing its viscosity temporarily and enabling complete discharge even from positions where it would normally stick to the wall.

Inventive Principle:

Principle #35Parameter changes

2Loss of substance

If the discharge unit is separated from the container to use remaining content, then complete discharge is possible, but content may be contaminated due to inflow of foreign materials

Engineering Contradiction:

Improveremaining contentVSAvoidcontamination

Core Design Contradiction:

Loss of substanceVSObject-affected harmful factors

Solution Approach 1:

The discharge unit acts as an intermediary between the container and the external environment. It includes a discharge pipe that extends into the container and a vibration unit that operates within the container environment, allowing the system to access and discharge remaining content without direct external contamination. The unit can be separated for cleaning but maintains a controlled interface during operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of substance

If the container is reversed and shaken to discharge remaining content, then complete discharge may be achieved, but it is difficult to discharge an accurate quantity of content

Engineering Contradiction:

Improveremaining contentVSAvoidquantity of content

Core Design Contradiction:

Loss of substanceVSMeasurement precision

Solution Approach 1:

The manual mechanical action of reversing and shaking the container is replaced with a controlled vibration mechanism. The vibration unit generates precise, controlled vibrations that systematically move the remaining content toward the discharge pipe without requiring the user to manually reverse and shake the container, thereby maintaining measurement precision while achieving complete discharge.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Loss of substance

If a lower plate is raised depending on use of content (airless container), then complete discharge is improved, but only cylindrical containers can be implemented which increases production cost

Engineering Contradiction:

Improveremaining contentVSAvoidproduction cost

Core Design Contradiction:

Loss of substanceVSEase of manufacture

Solution Approach 1:

The airless container concept is segmented into separate functional components: the container body can have any shape, while the discharge unit with its movable discharge pipe and vibration mechanism handles the task of complete discharge. This segmentation allows the container body to be manufactured in various shapes and sizes without the cost constraints of traditional airless containers that require a raised lower plate mechanism.

Inventive Principle:

Principle #1Segmentation
