Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the solenoid coil operates continuously to maintain pest repellent effectiveness, then the pest repellent performance is improved, but the temperature of the solenoid coil increases reducing service life
Solution Approach 1:
The solenoid coil is operated in periodic cycles rather than continuously. The controller activates the solenoid coil for specific time periods and then deactivates it, allowing the temperature to return to acceptable ranges while still maintaining effective pest repellent operation through repeated magnetic field generation
Solution Approach 2:
A temperature sensor continuously monitors the solenoid coil temperature and provides feedback to the controller. The controller uses this feedback information to determine when to activate or deactivate the solenoid coil, ensuring operation only when temperature is within acceptable ranges, thus preventing overheating while maintaining pest repellent effectiveness
2Duration of action of stationary object
If the PRD operates within ideal temperature range to extend service life, then the service life is improved, but the operational time is reduced
Solution Approach 1:
The system uses periodic on-off cycling of the solenoid coil to balance service life and operational time. By operating in repeated cycles rather than continuously, the system accumulates effective operational time over extended periods while allowing cooling intervals to protect the service life
Solution Approach 2:
The temperature sensor continuously monitors temperature in advance before critical overheating occurs. The controller uses this preliminary temperature information to proactively deactivate the solenoid coil before damage can occur, extending service life without significantly reducing overall operational time
3Reliability
If air is forced to flow out of the housing to prevent dust accumulation, then the service life is improved, but energy consumption increases
Solution Approach 1:
The air flow generation function is merged with the existing solenoid coil structure. The solenoid coil creates magnetic fields that move air through the housing to prevent dust accumulation, combining the pest repellent function with the dust prevention function in a single component, thereby avoiding additional energy-consuming dedicated fans or blowers
Solution Approach 2:
The solenoid coil serves dual purposes: generating magnetic fields for pest repellent operation and creating air flow to prevent dust accumulation. The system uses its primary operational function to simultaneously achieve dust prevention, eliminating the need for separate energy-consuming dust removal mechanisms

AI summary
Apparatus and associated methods relate to a pest repelling magnetic field generating device (PRD) having a temperature sensor to detect the temperature of a solenoid coil during operation. The detected temperature to be used to ensure that the PRD operates within an ideal temperature range. Additionally, a fan is oriented within a housing of the PRD to force the flow of air from inside a housing of the PRD to outside a housing the PRD. In an illustrative example, the PRD may shut off if the temperature of the solenoid coil moves outside the ideal temperature range. By operating the PRD within an ideal temperature range, the service life of the PRD may be extended. Further, the fan may mitigate dust collection within the housing of the pest repelling magnetic field generating device.
