Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If water cleaning or chemical dry cleaning is used, then cleaning effectiveness is improved, but environmental harm and labor intensity increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidenvironmental harm
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs ozone, a strong oxidant, to clean sensitive items such as theatre dresses and footwear. The ozone generator produces ozone gas that is introduced into the cleaning space, where it oxidizes and eliminates odors, sweat, and microbes without requiring water or harsh chemicals, thus achieving effective cleaning while being environmentally friendly

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

2Reliability

If water cleaning is used, then microbes and odors are removed, but mechanical strain and labor intensity increase

Engineering Contradiction:
Improvemicrobe and odor removalVSAvoidmechanical strain
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical cleaning methods (water washing, manual scrubbing) with a chemical-gas based cleaning system. Ozone gas is generated and circulated through the cleaning space, automatically oxidizing and eliminating microbes and odors without requiring manual labor or mechanical intervention, thus reducing both labor intensity and mechanical strain on sensitive items

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If ozone concentration is increased for faster cleaning, then cleaning speed is improved, but safety risks increase

Engineering Contradiction:
Improvecleaning speedVSAvoidsafety risks
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent incorporates an ozone concentration sensor that continuously monitors the ozone level in the cleaning space and provides feedback to the control unit. The control unit adjusts the ozone generator's operation based on this feedback, maintaining ozone concentration within a safe and effective range, thus enabling fast cleaning while ensuring safety

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent dynamically adjusts the ozone generation parameters (concentration, flow rate) based on the cleaning needs and safety thresholds. The system can increase ozone concentration for faster cleaning when safe, and reduce it when approaching safety limits, thus optimizing both cleaning speed and safety

Inventive Principle:
Principle #35Parameter changes

4Object-affected harmful factors

If ozone is used for cleaning, then environmental friendliness is improved, but ozone distribution control becomes more complex

Engineering Contradiction:
Improveenvironmental friendlinessVSAvoidozone distribution control
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent divides the cleaning space into multiple zones with separate ozone introduction points and circulation paths. The circulation channel system segments the ozone distribution, ensuring uniform delivery to different areas of the cleaning space, thus simplifying control while maintaining environmental friendliness

Inventive Principle:
Principle #1Segmentation

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

Enables quick, effective, and environmentally friendly cleaning of sensitive items by using ozone to eliminate odors and microbes without mechanical strain, with controlled ozone levels ensuring safety and efficiency.

Implementation Method 1

The generator 6 generates ozone from oxygen (O 2) by dissipating it first to one-atomic and combining the one-atomic oxygen with two-atomic oxygen to provide tri-atomic oxygen O 3, i.e. ozone.

Methodology Applied
Scientific EffectCorona discharge: Corona Discharge

Implementation Method 2

The circulation channel 27 also includes a cooling element 8, such as a Peltier element or a heat exchanger, which may cool the input air and, consequently, the ozone to be fed to the cleaning space.

Methodology Applied
Scientific EffectHeat exchange: Heat Exchanger

Implementation Method 3

The filtered air is passed via a heating element 25, such as a heat resistor, which may warm the input air.

Methodology Applied
Scientific EffectResistive heating: Joule Heating

Implementation Method 4

Triatomic ozone O 3 affects the objects to be cleaned in different ways depending on the microbes or odour molecules on the object.

Methodology Applied
Scientific EffectOxidation: Oxidation
