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 designs with many components.

Innovation Solution

An air pump type corrugated pipe with a hollow elastic body and a piston mechanism, featuring a one-way check valve and helicoidal surfaces for easy operation, reduces component count and cost while ensuring complete expulsion of viscous materials.

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 air pump mechanism is integrated directly into the container body, merging the pumping function with the container structure. The corrugated pipe serves dual purposes as both the pump mechanism and the structural component, eliminating the need for separate piston assemblies and reducing overall component count while maintaining effective material expulsion

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The corrugated pipe structure performs multiple functions: it acts as the pump mechanism, provides structural support, enables air intake for restoration, and facilitates material expulsion. This multi-functionality reduces the need for additional specialized components, simplifying the overall device while maintaining effectiveness

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 operation becomes difficult and inconvenient

Engineering Contradiction:
Improvecontent expulsion completenessVSAvoidoperation difficulty
Core Design Contradiction:
Loss of substanceVSEase of operation

Solution Approach 1:

The invention uses air pressure generated by compressing the corrugated pipe to drive the piston and expel contents. This pneumatic mechanism provides smooth, controlled force that is easier to operate than manual wrinkling and pushing, while ensuring complete expulsion of remaining contents through sustained pressure

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The corrugated pipe automatically restores its shape and draws in air through the air inlet after compression, creating a self-cycling pump action. This automatic restoration and air intake mechanism eliminates the need for manual intervention to reset the expelling action, making operation simpler and more convenient

Inventive Principle:
Principle #25Self-service
