Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the solenoid coil operates continuously to maintain pest repulsion effectiveness, then the pest repelling function is improved, but the temperature of the solenoid coil increases leading to reduced service life
Solution Approach 1:
The system implements periodic operation of the solenoid coil by cycling it on and off based on temperature feedback. The processor monitors the temperature sensor and activates the solenoid coil only when the temperature is within the ideal operating range, creating a periodic action pattern that prevents continuous overheating while maintaining pest repulsion effectiveness during active periods.
Solution Approach 2:
The system employs a feedback mechanism where the temperature sensor continuously monitors the solenoid coil temperature and provides feedback to the processor. The processor uses this feedback to control the solenoid coil operation, adjusting the duty cycle based on temperature conditions to maintain reliability while managing thermal accumulation.
2Reliability
If the solenoid coil operates at high power to ensure effective pest repulsion, then the pest repelling effectiveness is improved, but the service life of the PRD is reduced due to overheating
Solution Approach 1:
The system dynamically adjusts the operation of the solenoid coil based on real-time temperature conditions. Rather than operating at constant high power, the processor modulates the duty cycle dynamically - operating at high power when temperature is acceptable and reducing or stopping operation when temperature approaches critical levels, thereby extending service life while maintaining effectiveness when conditions permit.
Solution Approach 2:
The system changes the operational parameters of the solenoid coil based on temperature feedback. The processor adjusts the duty cycle percentage and timing intervals as parameters, modifying these parameters in response to temperature sensor readings to balance pest repelling effectiveness with thermal management and service life extension.
3Object-affected harmful factors
If the housing is sealed to protect internal components, then the protection against dust is improved, but dust accumulates inside the housing leading to reduced effectiveness
Solution Approach 1:
The system extracts the dust management function from the housing structure by introducing an active air moving mechanism. The fan actively removes accumulated dust from the housing interior and exhausts it outside, preventing dust buildup that would otherwise occur in a sealed housing, thereby maintaining internal cleanliness without compromising protective sealing.
Solution Approach 2:
The system uses pneumatic principles by employing a fan to create air flow that moves dust particles from the housing interior to the exterior. The fan generates pressure differential and air current that transports dust out of the sealed housing, utilizing fluid dynamics to solve the dust accumulation problem while maintaining housing integrity.

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.
