Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated analysis apparatus (GC-MS) is used separately from the particle counter to perform particle component analysis, then measurement precision of particle components is improved, but device complexity increases and analysis time increases
Solution Approach 1:
The patent merges the particle component analysis function into the particle counter by integrating a temperature controller and liquid-containing unit directly into the measurement system. This allows the particle counter to perform both particle counting and component analysis simultaneously, eliminating the need for separate GC-MS facilities and reducing overall device complexity while maintaining measurement precision.
Solution Approach 2:
The particle counter is transformed into a multi-functional apparatus that can perform both particle counting and particle component analysis. The temperature controller and liquid-containing unit enable the system to analyze different particle components by controlling aggregation temperatures, making the device universal for both particle detection and compositional analysis without requiring separate specialized equipment.
2Measurement precision
If a dedicated analysis apparatus (GC-MS) is used separately from the particle counter to perform particle component analysis, then measurement precision of particle components is improved, but analysis time increases
Solution Approach 1:
The patent enables continuous particle component analysis by integrating the temperature controller and liquid-containing unit into the particle counter's measurement flow. The system continuously monitors particles as they pass through the measurement chamber, allowing simultaneous particle counting and component analysis without the lengthy processing times required by separate GC-MS facilities, thereby maintaining precision while dramatically reducing analysis time.
3Adaptability or versatility
If temperature-controlled liquid aggregation is used to determine particle components, then particle component analysis capability is improved, but device complexity increases
Solution Approach 1:
The patent implements a nested structure where the liquid-containing unit and temperature controller are integrated within the particle counter's existing measurement chamber. The liquid-containing unit is positioned to allow gas flow through it, and the temperature controller is embedded within or adjacent to this unit, creating a compact nested arrangement that adds particle component analysis capability without significantly increasing overall device complexity.
