Solution Overview

Problem

Existing toothpaste and cosmetic containers face challenges in expelling highly viscous materials without residue, often resulting in wastage and inconvenience, and are costly due to complex components.

Innovation Solution

An air pump type corrugated pipe system with a hollow elastic body and a piston inside a tube, using air pressure to expel viscous materials through an outlet, where the pipe shrinks when pressed and restores shape when air flows in, reducing component count and cost.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a pump container with a piston is used to expel highly viscous material, then the material can be expelled more effectively, but the device complexity and cost increase due to multiple components

Engineering Contradiction:
Improveexpulsion effectivenessVSAvoidnumber of components
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the piston and the container body into a single integrated structure. The piston is formed as an integral part of the container body, eliminating the need for separate piston components and reducing assembly complexity while maintaining the pumping function for expelling highly viscous materials

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The container body serves multiple functions: it acts as both the storage vessel and the piston mechanism. The flexible body can deform to create pressure for expulsion and then restore its shape to draw in more material, combining storage, pumping, and actuation functions into a single universal component

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

2Loss of substance

If the body is strongly wrinkled and pushed to expel remaining contents, then the contents can be fully expelled, but the container becomes damaged and requires replacement

Engineering Contradiction:
Improvecontent expulsion completenessVSAvoidcontainer durability
Core Design Contradiction:
Loss of substanceVSStrength

Solution Approach 1:

The container employs a dynamically flexible body that can deform elastically during operation. The body flexes to create pressure for expelling contents and then naturally restores its original shape, allowing repeated use without permanent deformation or damage, thus maintaining both expulsion effectiveness and container durability

Inventive Principle:
Principle #15Dynamics

3Productivity

If a rigid tube structure is used for the container, then the structural strength is maintained, but the ability to expel highly viscous material without residue is reduced

Engineering Contradiction:
Improvematerial expulsion completenessVSAvoidstructural strength
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The patent uses a flexible tube body that can deform and collapse during the expulsion process. This flexibility allows the tube to conform to the viscous material and push it completely out without residue, while the material properties of the tube maintain sufficient structural strength for repeated use

Inventive Principle:
Principle #30Flexible shells and thin films

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

AI summary

The present invention relates to an air pump type corrugated pipe that holds highly viscose material such as toothpaste in a cylindrical container combined with the corrugated pipe and expels contents using air pressure according to compression of the corrugated pipe, and a container using the same. The container includes an air pump type operation device, a tube type body, and a piston. According to the present invention having such structure, highly viscose material is expelled easily and clearly without residue, thereby economic loss is reduced and convenience in use is provided, also the cost of the container is cheap due to its simple constitution.
