Solution Overview

Problem

Existing airbrush devices are costly, complex, and not portable, requiring compressed air that can be messy and pose safety risks, especially for novice users, and they often require time-consuming cleaning and additional hardware for color changes.

Innovation Solution

A portable airbrush apparatus with a built-in air pump, power source, and rotatable boom, featuring a sprayer head with a cartridge holder and valve system that allows for easy color changes and reduced mess, using compressed air to atomize fluids without direct exposure to the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a traditional airbrush system with external compressor is used, then sufficient compressed air supply is achieved, but portability and device complexity deteriorate

Engineering Contradiction:

Improvecompressed air supplyVSAvoidapparatus complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent combines the air compressor, power source, and airbrush components into a single integrated handheld device. The compressor is miniaturized and housed within the handle, eliminating the need for separate external equipment while maintaining sufficient air supply for atomization.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device is segmented into functional modules: a rechargeable power source in the handle, a compact compressor unit, a removable airbrush head, and replaceable cartridges. This modular design reduces overall complexity while maintaining performance.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If high viscosity paints are used in traditional airbrushes, then color saturation is improved, but sprayability and ease of operation deteriorate

Engineering Contradiction:

Improvecolor concentrationVSAvoidsprayability

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent changes the physical parameters of the paint by formulating it with lower viscosity while maintaining color saturation through concentrated pigments. The improved fluid dynamics allow easier atomization without requiring thinning agents.

Inventive Principle:

Principle #35Parameter changes

3Volume of moving object

If a small feed chamber is used in airbrushes, then device compactness is improved, but cleaning time and loss of time deteriorate

Engineering Contradiction:

Improvedevice sizeVSAvoidcleaning time

Core Design Contradiction:

Volume of moving objectVSLoss of time

Solution Approach 1:

The patent employs disposable cartridges that contain the paint supply. When empty or when color changes are needed, the entire cartridge is replaced rather than cleaned, eliminating cleaning time while maintaining a compact feed chamber design.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The paint supply is extracted into separate removable cartridges that can be quickly swapped. This separates the cleaning function from the spraying function, allowing rapid color changes without disassembling or cleaning the main airbrush body.

Inventive Principle:

Principle #2Taking out (Extraction)

4Adaptability or versatility

If free-handed airbrushing is used, then versatility in spraying direction is improved, but safety and object-generated harmful factors worsen

Engineering Contradiction:

Improvespraying flexibilityVSAvoidaccidental exposure risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a controlled release mechanism as an intermediary between the user and the atomized spray. A trigger-activated valve system and directional nozzle control the release of paint particles, maintaining spraying flexibility while preventing accidental exposure through engineered safety features.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An airbrush apparatus for use in generating a design on a desired object is disclosed. The apparatus and method of use are disclosed wherein the airbrush apparatus comprises a housing, boom, and sprayer head. A fluid to be applied is contained in individual cartridges and is drawn out by a vacuum effect caused by air that is being pumped from the housing across a feed tube which is in fluid communication with the cartridge.
