Innovation Solution
A two-liquid container design featuring a rotational assembly coupled to the lower end of a container main body, which includes a pipette assembly and piston-type valve system, allowing for easy mixing of contents by rotation, preventing contamination, and facilitating convenient storage and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two types of contents are mixed and stored in one container, then convenience of use is improved, but deterioration due to ingredient differences occurs
Solution Approach 1:
The container is divided into two separate compartments (first content storage space and second content storage space) within a single container body, allowing different ingredients to be stored separately to prevent deterioration while maintaining the convenience of a unified container structure.
Solution Approach 2:
The rotational assembly containing the second content is nested within the container main body that holds the first content. The rotational assembly can be inserted into and rotated within the container main body, enabling mixing when needed while maintaining separate storage conditions.
2Reliability
If two types of contents are stored in separate containers, then stability of contents is improved, but inconvenience in storage and purchase occurs
Solution Approach 1:
Two separate content storage systems are merged into a single container structure. The container main body and rotational assembly form an integrated unit that can be stored together as one product, eliminating the need for separate storage of multiple containers while maintaining the stability benefits of separate ingredient storage.
3Object-affected harmful factors
If medicines are mixed in a separate container, then contamination from foreign substances is prevented, but difficulty in mixing and waste of medicines occurs
Solution Approach 1:
A pipette assembly acts as an intermediary mechanism between the two content storage spaces. The pipette can be inserted through the container wall to transfer and mix contents in a controlled manner, preventing direct exposure to external contaminants while enabling easy mixing of the medicines.
4Manufacturing precision
If a complex valve system is added to control content flow, then precision of content control is improved, but device complexity increases
Solution Approach 1:
The piston-type valve utilizes the rotational motion of the assembly itself to control content flow. As the rotational assembly turns, the piston moves automatically within the valve body, opening or closing flow passages based on the rotation position, thereby achieving precise control without requiring separate complex control mechanisms.
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
The container effectively mixes first and second contents by rotation, minimizing contamination and storage inconveniences, ensuring the stability and usability of cosmetic and medicinal solutions.
Implementation Method 1
a cylindrical spring interposed between a lower upper surface of the cylinder and a lower surface of the piston-type valve and expanded when a screw coupling between the cylindrical screw column and the lower screw column of the piston-type valve is released to push the piston-type valve upward
Implementation Method 2
a lower end of the wiper member is bent inward and comes into contact with an outer circumferential surface of the pipette pipe to wipe the contents attached to the pipette pipe

AI summary
A two-liquid container capable of mixing solutions, including a container main body having a storage space in which first contents are stored, and having an upper part and a lower part that are open; a rotational assembly which is coupled to the lower open part of the container main body and in which second contents are stored; and a pipette assembly screwed to a screw thread formed on the outer circumferential surface of the upper open part of the container main body. The present invention exhibits an effect of coupling the rotational assembly filled with the second contents to the lower end of the container main body filled with the first contents so as to facilitate mixing of first and second contents by the rotation the rotational assembly.
