Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If filters are installed in air vents to prevent dust from entering the container, then dust protection is improved, but airflow is obstructed when dust builds up on the filter
Solution Approach 1:
The system performs preliminary measurement of air flow speed through the filter and compares it with a preset value to determine when filter replacement is needed, before complete airflow obstruction occurs. This proactive approach maintains airflow productivity by scheduling filter replacement at optimal intervals.
Solution Approach 2:
The system continuously measures air flow speed through the filter and provides feedback to determine filter replacement timing. This feedback mechanism allows dynamic adjustment of maintenance schedules based on actual filter condition, balancing dust protection with airflow efficiency.
2Ease of operation
If manual inspection of filter dust buildup is performed, then filter maintenance can be achieved, but measurement accuracy and automation are insufficient
Solution Approach 1:
The system replaces manual visual inspection with an automated measurement system using a pitot tube to measure air flow speed through the filter. This substitution provides objective, precise quantitative data about filter condition, eliminating the imprecision of manual assessment.
Solution Approach 2:
The system enables automatic determination of filter replacement timing through automated air flow measurement and comparison with preset values. This self-service capability reduces reliance on manual inspection while improving measurement precision and operational efficiency.

AI summary
A dust measurement system measuring the build up of dust on a filter includes a monitoring device, a pitot tube, and an environment control unit. The pitot tube head aligned with the filter. The environment control unit receives the measured speed of air flow and compares the measured speed with a preset value. When the measuring speed is greater than the preset value, the environment control unit outputs the first control signal to the monitoring device, to control the monitoring device to display that the filter does not need to be replaced. When the measuring speed is less than or equal to the preset value, the environment control unit outputs the second control signal to the monitoring device, to control the monitoring device to display that the filter needs to be replaced.
