Engineering Contradictions & Design Principles
Engineering 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
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
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
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
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
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

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 solution allows for easy and complete expulsion of highly viscous materials without residue, reducing economic loss and enhancing user convenience while minimizing container costs through a simplified design.
Implementation Method 1
a hollow elastic body of which one end is combined with the open end of the tube type body coaxially, and which is provided with pushing part having an air inlet at the other end of the body, wherein in case of pressing the pushing part, the closed internal volume of the body is maintained and the piston is moved by the air pressure
Implementation Method 2
in case of releasing of the power applied to the pushing part, air is flown in through the air inlet so that the body is restored

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.
