Engineering Contradiction Analysis
1Ease of operation
If manual remote operation is used to control the discharge nozzle direction, then the operator can control the fluid discharger, but it becomes difficult to effectively manage multiple fluid dischargers and increases operation time
Solution Approach 1:
The discharge nozzle is equipped with an automatic reciprocating mechanism that enables it to automatically change its discharge direction without continuous manual intervention. The nozzle reciprocates between predetermined angles, allowing the system to serve itself by automatically covering a wider area while the operator only needs to initiate and monitor the process.
Solution Approach 2:
The discharge nozzle performs periodic reciprocating motion between predetermined angular positions. This periodic action allows the fluid discharger to systematically cover different areas in a rhythmic pattern, improving dust suppression coverage across the work area without requiring continuous manual repositioning.
2Area of stationary object
If the discharge nozzle reciprocates automatically within a predetermined range, then dust suppression coverage is improved, but the system complexity increases
Solution Approach 1:
The dust suppression task is segmented into multiple discrete angular positions that the discharge nozzle visits during reciprocation. By dividing the coverage area into sectors corresponding to different nozzle angles, the system achieves comprehensive coverage through systematic segmentation of the discharge pattern.
Solution Approach 2:
The discharge nozzle transitions from a static fixed position to a dynamic reciprocating position. This dynamic capability allows the nozzle to adapt its discharge direction periodically, expanding the effective coverage area while maintaining a relatively simple mechanical implementation through controlled motion.

AI summary
A fluid discharger includes: a discharge nozzle configured to discharge fluid; a first rotation device configured to rotate the discharge nozzle; and a control device configured to control the first rotation device by remote operation. The control device includes a first mode control unit including a first automatic control unit configured to automatically perform reciprocating control of the discharge nozzle in a first rotation range set for each of the fluid dischargers; and a first switching unit configured to switch between a control signal to be outputted from the first automatic control unit and a control signal to rotate the discharge nozzle by a first rotation angle designated by remote operation. In a dust suppression system, this configuration can control the direction of the discharge nozzle by remote operation, and also can automatically reciprocate the direction of the discharge nozzle within a predetermined range.
