Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sensors rely on natural gas flow from the environment, then the system structure remains simple, but the monitoring sensitivity and response time deteriorate
Solution Approach 1:
The actuator performs preliminary action by actively drawing gas from the environment into the monitoring device before the sensor can detect it. This pre-concentration and pre-positioning of the gas sample enables faster and more sensitive detection compared to passive waiting for natural diffusion.
Solution Approach 2:
The actuator utilizes pneumatic principles to create controlled gas flow through the monitoring device. By applying mechanical force to move gas molecules, the system achieves enhanced mass transport to the sensor, improving detection sensitivity without requiring complex sampling infrastructure.
2Measurement precision
If large-scale environmental monitoring base stations are deployed, then monitoring coverage improves, but device complexity and deployment difficulty increase
Solution Approach 1:
The monitoring system is segmented into distributed micro-monitoring devices that can be deployed individually throughout the environment. Each device is a self-contained unit with integrated actuator-sensor-microprocessor components, allowing widespread deployment without requiring large centralized infrastructure.
Solution Approach 2:
Multiple functional components (actuator, sensor, microprocessor, communication module) are merged into a single integrated micro-monitoring device. This consolidation reduces the overall system scale requirements while maintaining comprehensive monitoring capabilities including gas detection, image capture, data processing, and wireless communication.
3Use of energy by moving object
If natural gas flow is used for sensor detection, then energy consumption remains low, but response time and real-time monitoring capability worsen
Solution Approach 1:
The actuator operates periodically to draw gas samples through the device at regular intervals. This periodic activation enables the system to maintain low overall energy consumption while achieving rapid response times during each sampling cycle, as the actuator only needs to operate briefly to concentrate and deliver gas to the sensor.
