Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If high-temperature and high-pressure atomizing agent is ejected from nozzle to contact atmospheric air, then aerosol is formed, but safety hazard occurs due to high-temperature droplets with kinetic energy that cannot be aerosolized

Engineering Contradiction:
Improveaerosol formation efficiencyVSAvoidsafety hazard from high-temperature droplets
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a pre-cooling channel that cools the atomizing agent before it reaches the atomizing wire. This preliminary cooling action reduces the temperature of the atomizing agent, preventing the formation of high-temperature droplets that cannot be aerosolized, thereby eliminating safety hazards while maintaining aerosol formation efficiency

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses cooling gas as an intermediary substance that flows through the pre-cooling channel to reduce the temperature of the atomizing agent before atomization. This intermediary cooling mechanism allows the atomizing agent to be at a safer temperature when contacting atmospheric air, while still enabling effective aerosol formation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If heating tube is heated continuously to ensure normal operation, then aerosol generation is stable, but preheating time is required and instantaneous atomization cannot be achieved

Engineering Contradiction:
Improveaerosol generation stabilityVSAvoidpreheating time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent pre-cools the atomizing agent before it reaches the atomizing wire through the pre-cooling channel. This preliminary cooling allows the system to achieve stable aerosol generation instantly without requiring continuous preheating of a large heating tube, as only a small portion of the atomizing agent needs to be heated at any given time

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of heating the entire atomizing agent flow continuously, the patent applies heating only to the portion of the atomizing agent that contacts the atomizing wire. This partial heating action reduces the thermal mass that needs to be maintained, enabling instantaneous atomization while maintaining stable aerosol generation

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If high power and energy consumption is used for continuous heating, then aerosol generation is maintained, but equipment size becomes large making portable applications difficult

Engineering Contradiction:
Improveaerosol generation continuityVSAvoidequipment size
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The patent heats only the necessary portion of the atomizing agent that contacts the atomizing wire, rather than continuously heating a large volume of atomizing agent. This partial heating approach significantly reduces the power and energy consumption requirements, allowing for compact, portable equipment design while maintaining continuous aerosol generation

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent divides the atomizing agent flow into segments, with only the portion contacting the atomizing wire being heated. This segmentation of the heating process reduces the overall energy requirement and allows for a more compact equipment design suitable for portable applications

Inventive Principle:
Principle #1Segmentation
