Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional detecting apparatus is used without a VOC detector, then the device complexity is reduced, but the VOC detection capability is lost
Solution Approach 1:
The detecting apparatus is enhanced by integrating a VOC detector into the existing detecting unit, enabling the same apparatus to perform both particle detection and VOC detection functions. This multi-functional design allows the system to detect various types of contaminants (particles and volatile organic compounds) using a single integrated device, thereby improving versatility without requiring entirely separate detection systems
2Device complexity
If a conventional VOC detector is used without a cleaning mechanism, then the device complexity is reduced, but the measurement precision deteriorates due to adhered VOCs
Solution Approach 1:
The VOC detector is equipped with a blowing unit that automatically activates after each detection cycle to blow away and remove VOCs that have adhered to the detecting unit. This self-cleaning mechanism enables the detector to maintain its own performance without requiring manual intervention or external cleaning equipment, thereby preserving measurement precision while avoiding excessive complexity
Solution Approach 2:
The blowing unit performs a preliminary cleaning action between detection cycles to prevent VOC accumulation on the detecting unit. By proactively removing contaminants before they interfere with the next measurement, the system ensures consistent detection accuracy without needing complex real-time correction mechanisms
3Device complexity
If the detecting unit remains stationary inside the chassis, then the device complexity is reduced, but the ability to remove adhered VOCs is limited
Solution Approach 1:
The detecting unit is made movable between an extended position (outside the chassis) and a retracted position (inside the chassis) through a displacement unit. This dynamic positioning capability allows the detecting unit to be moved to different locations for detection and cleaning operations, enabling more effective removal of adhered VOCs by exposing the detecting surface to the blowing unit's airflow from an optimal angle
