Solution Overview

Problem

Existing devices for mixing two substances, such as those used for repairing surface coatings, often fail to ensure reliable and defined mixing, leading to uncertainty about the formation of the desired mixture for application.

Innovation Solution

A device with a housing, reservoirs for the substances, a mixing chamber, and an actuating device that includes a mixing element and transmission elements to ensure defined mixing within the chamber, allowing for controlled mixing and dispensing of the mixture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual shaking is used to mix the two substances, then the device structure remains simple, but the mixing reliability and consistency are insufficient

Engineering Contradiction:
Improvemixing reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mixing element automatically mixes the substances through its rotation driven by the piston's linear movement, eliminating the need for manual shaking. The system serves itself by converting the emptying motion into mixing action through the transmission element coupling.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mixing element serves dual functions: it mixes the substances during transfer and can also mix the mixture in the mixing chamber if separation occurs. The same mechanical structure performs both mixing tasks without requiring additional components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If a mixing element with transmission elements is added to ensure defined mixing, then mixing reliability improves, but device complexity increases

Engineering Contradiction:
Improvemixing consistencyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The transmission element merges the piston's linear movement with the mixing element's rotation, combining two functions (emptying and mixing) into a single coupled mechanism. This integration ensures that mixing occurs automatically during the transfer process without requiring separate actuation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transmission element acts as an intermediary between the piston and mixing element, converting linear motion into rotational motion. This mediator ensures reliable and consistent mixing by providing a defined mechanical relationship between the emptying action and mixing action.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If substances are transferred directly without defined mixing, then the process is simple, but the mixture quality is uncertain

Engineering Contradiction:
Improvemixture qualityVSAvoidoperation simplicity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The system automatically performs mixing during the transfer process through the coupling of the piston and mixing element. The user simply operates the emptying device, and the mixing occurs self-service style without requiring separate manual mixing actions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mixing action is performed preliminarily during the transfer process itself, before the substances reach the mixing chamber. This preliminary mixing ensures proper mixing occurs in advance, and the mixing element can perform additional mixing in the chamber if separation occurs during storage.

Inventive Principle:
Principle #10Preliminary action
