Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction device operates continuously to filter brake dust particles, then the filtering effectiveness is maintained, but the filter element loads faster and lifespan is reduced
Solution Approach 1:
The suction device transitions from static continuous operation to dynamic conditional operation, adjusting its state based on real-time environmental data and driving mode detection. The processor enables or disables the suction device dynamically, optimizing both filtering effectiveness and filter element lifespan.
Solution Approach 2:
The system implements feedback control by continuously monitoring environmental conditions and driving modes, then adjusting the suction device operation accordingly. The processor receives data about pollution levels and braking events, and uses this feedback to determine when activation is necessary, preventing unnecessary filter loading.
2Reliability
If the suction device is activated in highly polluted environments, then brake dust filtration is attempted, but the filter element loads faster than usual
Solution Approach 1:
The processor monitors environmental pollution levels and compares them against thresholds. When external pollution is high, the system detects this through sensors and feedback mechanisms, then disables the suction device to prevent the filter from loading with excessive environmental particulates, not just brake dust.
Solution Approach 2:
The system changes the operational parameter of the suction device from 'always on' to 'conditionally on' based on environmental parameters. The processor adjusts the activation state according to measured pollution levels, driving mode, and braking event frequency, optimizing the balance between filtration need and filter protection.
