Solution Overview

Problem

Existing heterogeneous contents mixing vessels face contamination risks and inconvenience during assembly and use, as external foreign substances can enter and mix with stored contents, leading to coagulation, discoloration, or overflow issues when different contents are mixed and stored in a single vessel.

Innovation Solution

A vertically screw-coupled mixing vessel design with separate first and second vessels connected through a connection member, featuring discharge devices and a push button for simultaneous discharge, which prevents contamination and facilitates easy coupling while maintaining content separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the inner vessel is inserted into the outer vessel for assembling heterogeneous contents mixing vessel, then the different kinds of cosmetic contents can be simultaneously discharged and mixed, but external foreign substances enter the inside of the outer vessel during assembly or replacement, causing contamination of the stored contents

Engineering Contradiction:

Improveease of assemblyVSAvoidcontamination of stored contents

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention divides the inner vessel into separate components: the inner vessel body and the cap are assembled separately and then coupled together. This segmentation allows the cap to be attached after the inner vessel body is already positioned inside the outer vessel, preventing foreign substances from entering during the assembly process while maintaining ease of assembly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention performs preliminary assembly of the inner vessel components (inner vessel body and cap) before inserting them into the outer vessel. The cap is pre-attached to the inner vessel body in a controlled environment, ensuring that the contents are sealed before the assembly is inserted into the outer vessel, thus preventing contamination.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the inner vessel containing contents is inserted into the inlet portion of the opened outer vessel, then the vessels can be assembled for use, but the contents stored in the outer vessel overflow to the outside due to the volume or sudden insertion, contaminating the surroundings

Engineering Contradiction:

Improveease of assemblyVSAvoidoverflow of contents

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The invention performs preliminary assembly of the inner vessel with its cap before inserting it into the outer vessel. This ensures that the inner vessel is fully sealed and ready to receive contents without causing overflow during the insertion process, while still allowing easy assembly of the complete mixing vessel.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention introduces a bag as an intermediary component between the inner vessel and the outer vessel. The bag can be inserted into the inner vessel through the cap opening without causing overflow, and it serves as a flexible container that accommodates the contents while preventing spillage during the assembly process.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If different contents are stored in separate vessels and mixed in a separate vessel by opening inlets, then the contents can be mixed and used, but the user is required to directly mix and use the contents, increasing the risk of loss and decreasing portability

Engineering Contradiction:

Improveprevention of content lossVSAvoidcomplexity of mixing system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention merges the storage function and the mixing function into a single integrated device. The inner vessel stores one type of content and the outer vessel stores another type of content, and both are mixed within the same outer vessel system. This consolidation eliminates the need for separate mixing vessels and reduces the risk of content loss while maintaining portability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention uses a nested structure where the inner vessel is inserted into the outer vessel, and the cap of the inner vessel serves as the inlet for the outer vessel. This nested design allows multiple contents to be stored and mixed within a single portable device, eliminating the need for additional separate vessels and reducing the overall system complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)
