Solution Overview

Problem

Existing fluid dispersion devices for fragrant oils and disinfectants are noisy and lack uniform particle size distribution, making them unsuitable for quiet and predictable air sanitizing in enclosed spaces.

Innovation Solution

A fluid dispersion assembly powered by compressed air, featuring a diffusion unit with a diffusion chamber that forms uniform droplets, a cap with a discharge port, and a cartridge port with an atomizer assembly, which mixes compressed air and fluid to create a uniform dispersion, while incorporating noise-suppressing features like a suppressor assembly and silencer chamber.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If forced air is used for fluid dispersion, then automation and continuous operation are improved, but noise level increases making it disruptive in office environments

Engineering Contradiction:

Improveautomatic fluid dispersionVSAvoidnoise

Core Design Contradiction:

Extent of automationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a suppressor assembly as an intermediary component between the compressed air source and the fluid dispersion chamber. This suppressor assembly dampens the compressed air flow to reduce noise generation while still enabling automatic fluid dispersion operation, thus resolving the contradiction between automation and noise control.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If conventional fluid dispersion devices are used, then fluid delivery is achieved, but particle size distribution is non-uniform making dosing unpredictable

Engineering Contradiction:

Improvefluid deliveryVSAvoidparticle size uniformity

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent employs multiple nozzle assemblies positioned at different locations within the dispersion chamber, each creating localized uniform droplet patterns. The diffusion chamber design also creates specific local flow conditions that promote uniform particle size distribution throughout the dispersed fluid, enabling predictable dosing while maintaining productivity.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If spray cans are used for fluid delivery, then portability and simplicity are improved, but user interaction is required repeatedly and manually

Engineering Contradiction:

ImprovesimplicityVSAvoidmanual spraying frequency

Core Design Contradiction:

Ease of operationVSExtent of automation

Solution Approach 1:

The system is designed to be self-service through automatic operation. The fluid dispersion assembly continuously or periodically dispenses fluid automatically using compressed air, eliminating the need for repeated manual user interaction required by spray cans, while maintaining ease of operation through simple setup and maintenance.

Inventive Principle:

Principle #25Self-service

4Duration of action of stationary object

If plug-in heating devices are used for oil dispersion, then continuous operation is achieved, but energy consumption increases and fire hazard is created

Engineering Contradiction:

Improvecontinuous operationVSAvoidenergy consumption

Core Design Contradiction:

Duration of action of stationary objectVSUse of energy by moving object

Solution Approach 1:

The patent replaces the thermal heating mechanism with a mechanical/compressed air-based dispersion system. Instead of heating oils continuously via electrical outlets, the system uses compressed air to atomize and disperse the fluid, achieving continuous operation without the energy consumption and fire hazards associated with heating elements.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A fluid dispersion assembly comprises a diffusion unit disposed in fluid communication with a fluid container, the assembly being powered by a compressed air source. The diffusion unit at least partially defines a diffusion chamber, and includes a diffusion assembly containing an atomizer assembly which, in combination with the diffusion chamber, generates a fluid dispersion from a mixture of compressed air and an operative fluid, for example, fragrant oils, essential oils, odor neutralizers, disinfectants such as triethylene glycol, air sanitizers, etc. The diffusion unit may include a suppressor assembly and/or a silencer assembly to reduce the amount of noise generated during operation. In one alternate embodiment, a modified diffusion chamber is provided which functions as a suppression chamber, thereby reducing the noise generated during operation of the assembly.
