Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mixing containers face challenges in reliably and efficiently releasing specified amounts of powder, liquid, or solid substances into a dissolving agent, often resulting in spills and requiring double handling, which is cumbersome and uneconomical, especially when preparing different concentrations of household detergents.

Innovation Solution

A mixing container design featuring a body with receiving chambers for press-through pack sheets, a support structure with releasing holes, and a holding mechanism that allows external compression to release substances into the container, eliminating the need for manual measurement and enabling reusable and adjustable concentration preparation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user pours measured solute and solvent into the spray container through the small opening, then the mixing can be completed, but the user may accidentally spill the measured substances and the operation becomes troublesome

Engineering Contradiction:

Improveease of pouring substancesVSAvoidreliability of preventing spills

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The container is divided into two separate chambers: a storage chamber for holding the concentrated detergent and a mixing chamber for mixing with water. This segmentation allows the concentrated detergent to be stored separately and released in controlled amounts, preventing spills during the pouring operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The concentrated detergent is pre-measured and stored in the storage chamber in ready-to-use quantities. When mixing is needed, the predetermined amount is released into the mixing chamber, eliminating the need for manual measurement and reducing spill risk during the operation.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the user mixes measured solute and solvent in a different container before placing into spray container, then spills are avoided, but double work is required which is troublesome

Engineering Contradiction:

Improvereliability of preventing spillsVSAvoidease of mixing operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The storage chamber and mixing chamber are merged into a single integrated container system. The storage chamber can be positioned to allow gravity-fed transfer of concentrated detergent into the mixing chamber, combining the storage and mixing functions in one device and eliminating the need for separate containers and double handling operations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

A transfer mechanism (such as a valve or gravity feed system) acts as an intermediary between the storage chamber and mixing chamber, enabling controlled transfer of the concentrated detergent without requiring the user to manually handle and pour the substance, thus preventing spills while maintaining ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If separate areas store different substances to be simultaneously released and mixed, then mixing can be achieved, but selective release of intended substance is not possible

Engineering Contradiction:

Improveproductivity of mixingVSAvoidease of selective release

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The storage chamber is designed with localized control features such as individual valves or selectively positionable partitions that allow the user to control the release of concentrated detergent from specific areas. This enables selective release of the intended substance while maintaining the productivity benefit of having pre-separated components ready for mixing.

Inventive Principle:

Principle #3Local quality

AI summary

A mixing container includes a body having an upper opening and containing a dissolving agent, at least one receiving chamber protruding outward from an inner peripheral surface of the body, having a hollow defined in the protrusion where a press-through pack (PTP) sheet is fittable from inside the body, and formed from a flexible material, a support including a plate and a releasing hole that communicates with an inlet of the hollow in the receiving chamber when the plate is installed on the inner peripheral surface of the body and allows a substance stored in the PTP sheet to be released into the body, and holds an edge of the PTP sheet between the inner peripheral surface of the body and the plate, and a holding structure that holds the support on the inner peripheral surface of the body.
