Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual ion-spraying is performed from close range, then sterilization and disinfection effects are improved, but time consumption and operational effort increase
Solution Approach 1:
The ion-spraying system performs automated detection and spraying operations without requiring manual intervention. The controller automatically controls the ion-spraying device to spray ions onto detected targets, enabling the system to serve itself and eliminating the need for continuous manual operation while maintaining effective sterilization coverage
Solution Approach 2:
The patent replaces manual mechanical spraying operations with an automated control system that uses sensors to detect targets and a controller to operate the ion-spraying device. This substitution of mechanical human operation with an automated electromechanical system reduces time consumption while maintaining the reliability of sterilization effects
2Reliability
If ions are sprayed from close range, then sterilization effectiveness is improved, but operational complexity and safety risks increase
Solution Approach 1:
The system incorporates sensors that detect targets and provide feedback to the controller. The controller uses this feedback information to automatically adjust and control the ion-spraying operation, eliminating the need for complex manual judgment and operation while ensuring effective sterilization through automated closed-loop control
Solution Approach 2:
The controller acts as an intermediary between the sensor detection system and the ion-spraying device. It processes detection information and automatically controls the spraying operation, simplifying the overall system operation by mediating between detection and execution without requiring direct manual intervention
3Manufacturing precision
If ion-spraying is performed manually each time, then localized treatment is achieved, but consistency and frequency of treatment decrease
Solution Approach 1:
The automated system enables continuous ion-spraying operations without interruption. The controller continuously monitors detection signals and maintains continuous spraying action on detected targets, ensuring consistent and frequent treatment that eliminates the gaps inherent in manual intermittent operation while maintaining precise localized treatment
4Measurement precision
If air quality abnormalities are detected, then monitoring capability is improved, but ability to address the source remains insufficient
Solution Approach 1:
The system performs preliminary detection of air quality abnormalities using sensors before implementing the corrective action of ion-spraying. By detecting targets such as odor sources in advance and then automatically spraying ions onto them, the system addresses the source of abnormalities proactively rather than reactively, improving source elimination effectiveness while maintaining monitoring precision

AI summary
A communication unit receives spraying target information indicating a spray target. A spraying target detector detects the spray target indicated in the spraying target information in space. A spray control unit is a unit that performs ion-spraying processing on the spray target at a predetermined frequency. In the ion-spraying processing, the spray control unit determines a moving direction of an ion spraying apparatus from a current location to the detected spray target, and sprays ions on the spray target when a distance between the spray target and the ion spraying apparatus is within a first threshold value. A flight control unit controls a flight of the ion spraying apparatus in the moving direction.
