Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If external power sources or heating mechanisms are used to atomize and deliver fluid, then the fluid can be effectively atomized and delivered, but the fluid components may be damaged or chemically altered and harmful substances may be introduced

Engineering Contradiction:

Improvefluid atomization and delivery effectivenessVSAvoiddamage to fluid components and harmful chemical formation

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces thermal energy systems (heating mechanisms) with a mechanical suction system powered by human mouth suction. The fluid is atomized through the action of air flow generated by suction, not by heating, thereby avoiding chemical alteration of the fluid components while maintaining effective atomization and delivery.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The device is designed to be self-powered by the user's own mouth suction, eliminating the need for external power sources. The suction generated by the user directly drives the fluid atomization and delivery process, avoiding the introduction of harmful substances associated with external power sources while maintaining operational effectiveness.

Inventive Principle:

Principle #25Self-service

2Productivity

If external power sources are used to power the device, then the fluid can be effectively atomized and delivered, but the device loses portability and independence

Engineering Contradiction:

Improvefluid atomization and delivery effectivenessVSAvoiddevice portability and independence

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The device is designed to be self-powered by the user's own mouth suction, eliminating the need for external power sources. This makes the device portable and independent, while the suction mechanism effectively drives the fluid atomization and delivery process.

Inventive Principle:

Principle #25Self-service

3Device complexity

If the nozzle exit directly opens into the fluid reservoir, then the device structure is simplified, but large droplets may escape into the ambient air

Engineering Contradiction:

Improvedevice structure simplicityVSAvoidlarge droplet escape into ambient air

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary structure (the fluid-air mixture channel) between the nozzle exit and the ambient environment. This channel allows the fluid-air mixture to travel from the nozzle to the fluid-air outlet while preventing large droplets from escaping into the ambient air, thus resolving the contradiction between structural simplicity and droplet containment.

Inventive Principle:

Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Delivers a fine mist of fluid without heating, preserving the integrity of the fluid components and avoiding harmful chemical formation, while being portable and powered solely by mouth suction.

Implementation Method 1

The choke point G of the air duct F is a point in which the air duct F narrows, resulting in a lower cross-sectional area of the air duct F. In operation, atomized fluid A exits the atomization outlet C when air of sufficiently high pressure enters air inlet B.

Methodology Applied

Scientific EffectVenturi effect: Venturi Effect

Implementation Method 2

a liquid in a liquid reservoir is pulled into a stream of fast flowing air, atomizing the liquid into droplets

Methodology Applied

Scientific EffectAtomization:

Implementation Method 3

A reservoir hole H allows atomized fluid A that collects within the air duct F and around atomization outlet C to flow back into the reservoir

Methodology Applied
