Solution Overview

Problem

Existing devices for preparing and dispensing mixed substances are limited by the need for gravity-driven dispensing, which restricts their use based on the orientation and properties of the first substance, particularly preventing the use of viscous substances.

Innovation Solution

A device design that allows for the first substance to be pressurized within a container and dispensed into a second container through a rotational alignment of outlets, facilitated by a piston or pressurized medium, with a third opening in the second container for direct removal of the mixed substance, and a closure part that connects and rotates with the containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If gravity-driven dispensing is used, then the device structure is simple, but the device cannot handle viscous substances and is limited by orientation

Engineering Contradiction:

Improvehandling flexibilityVSAvoiddevice structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The first substance is pre-filled into the first container in a controlled environment (e.g., filling station) before the device is used by the end user. This preliminary filling action allows the device to be sealed and pressurized, enabling it to function independently of gravity and orientation during actual use.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A pressurized medium (gas or liquid under pressure) is introduced into the first container to actuate the piston and drive the first substance through the outlet formation into the second container. This pneumatic/hydraulic mechanism replaces gravity-driven flow, allowing viscous substances to be dispensed in any orientation.

Inventive Principle:

Principle #29Pneumatics and hydraulics

2Adaptability or versatility

If a piston and pressurized medium are used, then viscous substances can be dispensed, but the device complexity increases

Engineering Contradiction:

Improvesubstance viscosity rangeVSAvoidmechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The piston mechanism serves multiple functions: it acts as a barrier to separate the pressurized medium from the first substance during filling, a dispensing mechanism to push the substance through the outlet, and a pressure transmission element to convert pressurized medium energy into substance flow. This multi-functionality reduces the need for additional separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device is divided into separate fillable containers (first container with piston, second container) that can be independently filled and sealed. This segmentation allows each container to be optimized for its specific function and enables flexible assembly and disposal configurations.

Inventive Principle:

Principle #1Segmentation

3Productivity

If the mixed substance must pass back through the first container, then the device structure is simplified, but the dispensing efficiency is reduced

Engineering Contradiction:

Improvedispensing efficiencyVSAvoidcontainer configuration

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Instead of having the mixed substance return through the first container to the application end, the design inverts the flow path by providing a third opening directly in the second bottom of the second container. This allows the mixed substance to be removed directly from the second container where it was created, eliminating the inefficient return path.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A device for preparing and dispensing a mixed substance has a first container containing a first substance and a second container containing a second substance, the containers having a common central axis. The first container has a ceiling with an optional first opening, a first wall, and a first base, the second container having a second wall and a second base, the first base having an outlet formation which can be closed by a closure part. The closure part forms a lid for the second container by connection to a free edge of the second wall. The outlet formation is brought into alignment with a second opening in the closure part by rotating the first container relative to the closure part, clearing the way for the first substance into the second container. The mixed substance can be removed from the device through a third opening in the container bottom.
