Solution Overview
Problem
Existing detection systems for fine particles and microorganisms in gases face accuracy issues due to contamination from residue in cyclone collection devices, leading to decreased detection precision when continuously collecting and detecting particles.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the collection and detection of target detection particles are repeatedly performed continuously, then the productivity is improved, but the measurement precision is lowered due to contamination of the residue
Solution Approach 1:
The cleaning part performs preliminary cleaning action by swirling cleaning liquid through the cyclone chamber before each detection cycle to prevent residue accumulation. This preliminary cleaning ensures that the detection chamber is free from contaminants that would otherwise degrade measurement precision during continuous operation.
Solution Approach 2:
A cleaning liquid is introduced as an intermediary substance to remove residue from the cyclone chamber walls. The cleaning liquid acts as a mediator between the residue contamination and the detection system, allowing continuous operation without direct contact between residue and detection sensors.
2Reliability
If a separate airflow generation mechanism is added for cleaning, then the cleaning effectiveness is improved, but the device complexity increases
Solution Approach 1:
The airflow generation mechanism serves dual functions: it generates swirling airflow for particle collection during detection operations, and simultaneously generates swirling airflow to circulate cleaning liquid for chamber cleaning. This multi-functionality eliminates the need for separate cleaning airflow generators, maintaining cleaning effectiveness while reducing device complexity.
Solution Approach 2:
The system performs self-service cleaning by utilizing its own existing airflow generation capability to circulate cleaning liquid through the cyclone chamber. The detection device cleans itself without requiring external or separate cleaning mechanisms, thereby reducing overall system complexity while maintaining reliable cleaning effectiveness.
