Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a capturing component is used to capture fine particles, then particle capture efficiency is improved, but the component requires frequent replacement
Solution Approach 1:
The patent changes the physical state parameter of the capturing component from solid (traditional filters) to liquid (liquid capturing component). This liquid capturing component absorbs fine particles through absorption action, and since liquids can be continuously circulated and regenerated, the component does not require frequent replacement, resolving the contradiction between capture efficiency and service life
Solution Approach 2:
The patent utilizes phase transition by employing a liquid capturing component that can change state or be regenerated through thermal or other processes. The liquid capturing component can be heated to evaporate absorbed particles or otherwise regenerated, allowing continuous operation without replacement, thus extending component service life while maintaining capture efficiency
2Object-generated harmful factors
If a traditional filter is used to capture particles, then particles are captured, but the filter requires frequent replacement
Solution Approach 1:
The liquid capturing component performs self-regeneration through circulation and heating processes. The system can automatically regenerate the capturing component by heating it to evaporate absorbed particles, eliminating the need for manual replacement and reducing downtime, thus resolving the contradiction between particle capture and operational continuity
Solution Approach 2:
The patent enables continuous operation by using a liquid capturing component that can be continuously circulated and regenerated. Unlike solid filters that must be replaced, the liquid component can be continuously processed through heating and evaporation, maintaining harmful factor reduction without interruption, thus eliminating downtime losses

AI summary
A fine-particle-capturing device includes: a support unit made of metal and disposed near a fine-particle source capable of generating fine particles in a vaporized state; an exhaust unit having an exhaust opening that opens in the support unit made of metal, the exhaust unit causing air containing the fine particles generated by the fine-particle source to flow in a discharging direction from the exhaust opening; and a capturing component provided to cover the exhaust opening of the exhaust unit, the capturing component capturing the fine particles. The capturing component includes: a capturing unit including a plate-shaped member made of metal in which micropores are regularly arranged, the micropores extending through the plate-shaped member in a thickness direction and having a polygonal cross-section; and a holding unit made of metal having a cavity at least in a region between the capturing unit and the exhaust opening, the holding unit holding the capturing unit at a location separated from the exhaust opening. The holding unit is supported by the support unit at a downstream location in a direction in which the air passes through the capturing unit.
