Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple nozzles are used to spray atomized water in the test chamber, then fog can be generated, but unevenness in fog density occurs around the subject

Engineering Contradiction:
Improvefog densityVSAvoidfog density uniformity
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

A blower is introduced as an intermediary device between the nozzles and the subject. The blower draws atomized water vapor generated by the nozzles and forcibly circulates it throughout the test chamber, ensuring uniform distribution of fog density around the subject without requiring direct spraying near the subject area

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention utilizes pneumatic principles by employing a blower to create air flow that carries atomized water vapor. The blower generates controlled air currents that distribute the fog uniformly across the test chamber, replacing the need for multiple precisely positioned nozzles and achieving homogeneous fog density through fluid dynamics

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If multiple nozzles spray atomized water directly in the test chamber, then fog environment is formed, but visibility measurement reliability decreases due to density unevenness

Engineering Contradiction:
Improvevisibility measurement reliabilityVSAvoidfog density distribution
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The blower serves as a mediator that decouples the fog generation process from the subject area. By introducing and circulating atomized water vapor through controlled air flow rather than direct spraying, the system achieves uniform fog distribution that ensures reliable visibility measurements around the subject

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention changes the physical state and distribution parameters of the atomized water. Instead of delivering liquid or concentrated vapor directly to the subject area, the blower disperses the atomized water throughout the chamber air, creating a homogeneous fog environment with consistent optical properties for reliable measurement

Inventive Principle:
Principle #35Parameter changes

AI summary

A fog environment forming apparatus includes a spraying portion that discharges atomized water for forming a fog environment, and a blower that suctions air containing the atomized water discharged from the spraying portion and causes the air containing the suctioned water to flow out toward a subject while mixing the air. The blower is configured to cause the mixed air to flow out toward the subject within a height range of the subject.
