Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If water spraying is used for dust suppression, then dust control is improved, but water wastage increases when excess water is sprayed
Solution Approach 1:
The system uses dust concentration sensors to continuously monitor dust levels and provides feedback to the controller, which adjusts the water discharge rate accordingly. This closed-loop feedback mechanism ensures water is sprayed only at the necessary rate to control dust, preventing both excessive water usage and insufficient dust suppression.
Solution Approach 2:
The water discharge rate is made dynamically adjustable based on real-time dust concentration measurements. The system transitions from static fixed-rate spraying to dynamic variable-rate spraying, allowing optimization of water usage according to actual dust generation conditions during drilling operations.
2Object-affected harmful factors
If water spraying is used for dust suppression, then dust control is improved, but system complexity increases due to need for precise control
Solution Approach 1:
The system is designed to automatically monitor dust levels and self-regulate water discharge without manual intervention. The controller autonomously adjusts the discharge rate based on sensor feedback, making the system self-sufficient and reducing the need for complex manual control mechanisms while maintaining effective dust suppression.
Solution Approach 2:
The system replaces complex mechanical control mechanisms with electronic sensing and control. Dust concentration sensors and electronic controllers substitute for manual mechanical adjustments, simplifying the overall system while enabling precise control of water discharge rates based on real-time conditions.
3Device complexity
If fixed water discharge rate is used, then system simplicity is maintained, but dust control efficiency decreases under varying conditions
Solution Approach 1:
The water discharge rate transitions from a fixed static value to a dynamic variable that automatically adjusts to match changing dust generation conditions. This dynamic adjustment maintains simple system operation while significantly improving dust control efficiency across varying drilling conditions and ground types.

AI summary
A method for dust suppression for an autonomous drilling machine operating at a work site. The method comprises of generating by a perception module perception data of the work site, receiving at least one machine parameter from a machine sensor of the autonomous drilling machine, predicting by a controller a dust level for the autonomous drilling machine at the work site based on one of the perception data or the machine parameter, determining a fluid discharge rate for a fluid discharge unit based on the predicted dust level, and adjusting the fluid discharge rate based on dust level detected during the drilling operation.
