Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional dispensing containers for mixing heterogeneous substances do not allow users to select the type of content used, leading to premature mixing and potential spoilage or performance degradation.

Innovation Solution

A dispensing container design featuring a first container with a partitioned interior space for a first content and a separately insertable second container with its own pump module, allowing users to select and insert different second containers with various contents, which are dispensed through a shared nozzle tip.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two types of contents are stored separately within a single container with two pumps, then the contents can be mixed immediately before dispensing, but the user cannot select which type of content to use

Engineering Contradiction:

Improvecontent selection capabilityVSAvoidcontainer structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container is divided into a first container with a first interior space for storing a first content, and a second container that can be inserted into the first container with a second interior space for storing a second content. Each container has its own pump module, allowing independent selection and dispensing of different content types without mixing them together in storage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second container is inserted into the first container, creating a nested structure where the smaller second container fits within the larger first container. This nested design allows the user to select between different second containers with different contents while maintaining a compact overall structure, resolving the contradiction between versatility and complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If two different types of contents are mixed together in the container, then a synergetic effect is achieved, but premature mixing before use causes the contents to spoil or exhibit lowered performance

Engineering Contradiction:

Improvecontent performanceVSAvoiddispensing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The two different types of contents are stored separately in the first and second containers before use, preventing premature mixing. The pump modules are positioned and connected in advance, so that mixing occurs only at the moment of dispensing when needed, ensuring content reliability while maintaining dispensing efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The pump modules act as intermediaries that control the mixing process. They draw the first content from the first container and the second content from the second container, mixing them only during the dispensing process. This intermediary mechanism ensures that contents are mixed at the optimal moment for achieving synergetic effects without premature spoilage.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If a single container holds two types of contents with separate pumps, then mixing can occur before dispensing, but the structure becomes complex and user selection is limited

Engineering Contradiction:

Improveuser selection optionVSAvoidpump module configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The first container serves multiple functions: it stores the first content, provides structural support, and acts as the outer housing for the insertable second container. The pump modules are designed to work with either the first content alone or in combination with the second content, providing universal functionality that simplifies operation while maintaining a manageable structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A dispensing container for discharging different types of contents includes a first container, a second container, a first pump module coupled to the first container, and a second pump module coupled to the second container. The first container includes an insertion space and a first interior space separated from the insertion space by a partition wall. The second container is inserted into the insertion space and includes a second interior space. The first pump discharges a first content filled in the first interior space, and the second pump module is inserted into the second interior space when the second container is inserted into the insertion space. The second pump module also discharges a second content filled in the second interior space.
