Conventional disinfection methods using chemicals are unsafe and inconvenient, as they can be toxic to humans and pollute the environment, and existing technologies do not effectively utilize nanometer-sized bubbles for cleaning.

Innovation Solution

A disinfectant appliance with a nanometer disinfectant function, comprising a gas generator and an emulsification pressure-releasing device that pressurizes water to create innumerable tiny bubbles for effective cleaning, using a pressurizing device, pressure-equalizing device, and pressure-releasing device to emulsify liquids and remove dirt, bacteria, and viruses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemicals are used to sterilize objects, then bacteria and viruses are killed, but the chemicals are toxic to humans and pollute the environment

Engineering Contradiction:
Improvesterilization effectivenessVSAvoidtoxicity and environmental pollution
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses ozone (O3) as a strong oxidant to sterilize objects. Ozone generates highly reactive oxygen species that destroy bacterial cell walls and viral structures through oxidation, achieving effective sterilization without the toxicity and environmental pollution associated with conventional chemical sterilants like formaldehyde or chlorine.

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

Solution Approach 2:

The patent utilizes the phase transition of ozone from gas to liquid state through compression and cooling processes. This phase transition enables ozone to be stored and transported in a condensed form, then released as gas to perform sterilization, improving storage efficiency while maintaining the strong oxidizing properties needed for effective disinfection.

Inventive Principle:
Principle #36Phase transitions

2Productivity

If more gas is compressed into water to increase emulsification effect, then more tiny bubbles are generated for better cleaning, but greater pressure is needed requiring larger device size

Engineering Contradiction:
Improvecleaning effectivenessVSAvoiddevice size
Core Design Contradiction:
ProductivityVSVolume of stationary object

Solution Approach 1:

The patent changes the physical parameters of the system by using a membrane separator with specific pore sizes (0.01-10 micrometers) and controlling pressure differential (0.1-10 bar). This allows generation of nanometer-sized bubbles with high cleaning effectiveness while maintaining a compact device structure, as the membrane filter enables efficient gas-liquid separation at lower pressures compared to conventional compression methods.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs pneumatic principles through the use of a membrane separator that allows selective gas passage while retaining liquid. The system uses pressure differential driven by a pump to push gas through the membrane, creating nanometer bubbles in the liquid phase. This pneumatic-hydraulic approach generates effective bubbles with smaller device size compared to purely mechanical compression methods.

Inventive Principle:
Principle #29Pneumatics and hydraulics
