Solution Overview

Problem

Existing heterogeneous contents mixing containers face challenges with complex assembly processes and leakage issues due to inadequate sealing, leading to reduced productivity and increased risk of contamination.

Innovation Solution

The design incorporates a first content receiving member with an upper separation cap and a lower fixing cap, featuring integrally formed connection pipes and a sealing ring, along with a sealing member on the pump housing, to simplify assembly and enhance sealing by direct insertion of connection pipes and dual injection processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate containers are used for different contents and contents are mixed in a separate container, then chemical reactions and deterioration are prevented, but convenience of use deteriorates and loss of container occurs

Engineering Contradiction:

Improveprevention of chemical reaction and deteriorationVSAvoidconvenience of use

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The first content receiving member (containing first content) is nested within the second content container body (containing second content). The upper separation cap and lower fixing cap form a nested structure that allows both contents to be stored in a single container while remaining isolated, eliminating the need for separate containers and improving convenience without compromising prevention of chemical reactions

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The first content receiving member is divided into an upper separation cap and a lower fixing cap that can be separated. The separation membrane is segmented to allow controlled mixing. This segmentation enables the contents to remain isolated during storage (preventing chemical reactions) while allowing easy separation and mixing when needed (improving convenience of use)

Inventive Principle:

Principle #1Segmentation

2Reliability

If discharge tube is additionally formed to pass through upper separation cap and lower fixing cap, then content suction passage is formed, but assembling process becomes complicated and productivity deteriorates

Engineering Contradiction:

Improveformation of content suction passageVSAvoidassembling process complexity

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The discharge tube is merged with the upper separation cap and lower fixing cap to form an integrated structure. The discharge tube is formed as an integral part of these components rather than being a separate piece that requires additional assembly steps. This merging simplifies the assembling process and improves productivity while ensuring the content suction passage is properly formed

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If O-ring is coupled into gap between pump housing and lift guide pipe, then sealing is improved, but O-ring is pulled up when pump housing moves and sealing ability deteriorates

Engineering Contradiction:

Improvesealing abilityVSAvoidsealing stability during movement

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The O-ring sealing solution is extracted and replaced with a sealing structure that is integrated into the pump housing and lift guide pipe assembly. The sealing member is positioned and fixed in a manner that prevents it from being pulled up during movement, eliminating the instability issue while maintaining sealing ability

Inventive Principle:

Principle #2Taking out (Extraction)

4Reliability

If lower cover is pressed to break separation membrane, then contents are mixed, but multiple steps are required and ease of operation deteriorates

Engineering Contradiction:

Improvemixing of contentsVSAvoidnumber of steps required

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The separation membrane is pre-positioned and configured within the first content receiving member such that it can be easily broken or pierced by the discharge tube during normal operation. This preliminary arrangement eliminates the need for pressing the lower cover and multiple complex steps, allowing contents to be mixed with a simple operation while ensuring reliable mixing

Inventive Principle:

Principle #10Preliminary action

AI summary

A heterogeneous contents mixing container with improved productivity and sealing ability. The container includes a container body for containing a second content and a first content receiving member is formed in the container body to contain a first content. The receiving member includes an upper separation cap and a lower fixing cap. A shoulder is rotatably coupled to the container body and a lift guide member is fixed to the container body and formed with a spiral groove. A lift member moves upwardly by rotation of the shoulder and is formed with a lift protrusion. A pump housing moves upwardly with the lift member. A discharge pump moves upwardly with the pump housing to pump the first and second contents mixed with each other. A push button is coupled to the discharge pump to be movable up or down and is formed with a discharge outlet.
