Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If liquid flow rate is increased to reduce dust, then dust mitigation effectiveness is improved, but water consumption increases
Solution Approach 1:
The system dynamically adjusts the liquid flow rate based on real-time milling parameters (depth, speed, material type) rather than using a fixed flow rate. The controller continuously monitors operational conditions and modifies water delivery to match actual dust generation levels, optimizing dust suppression while minimizing water consumption.
Solution Approach 2:
The system changes physical parameters (liquid flow rate, pressure, temperature) based on detected milling conditions. Sensors monitor depth, speed, and material properties, and the controller adjusts corresponding liquid delivery parameters to achieve effective dust mitigation with minimal water usage.
2Object-affected harmful factors
If liquid flow rate is increased to maintain dust mitigation ratio, then dust control is improved, but system complexity increases
Solution Approach 1:
The system incorporates sensors that continuously monitor milling parameters (depth, speed, material removal rate) and feed this information back to the controller. The controller processes this feedback and automatically adjusts liquid flow rate and pressure to maintain optimal dust mitigation, creating a closed-loop control system that simplifies operation despite the complexity of multiple interacting components.
Solution Approach 2:
The controller serves multiple functions: monitoring milling parameters, calculating material removal rate, determining optimal liquid flow rate, controlling spray pressure, and adjusting flow distribution across multiple spray banks. This multi-functionality consolidates what would otherwise require separate systems into a single integrated control unit.
