Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single working mode is used in traditional mosquito repellent devices, then the device structure is simple, but the device cannot adapt to various use scenarios resulting in poor effectiveness
Solution Approach 1:
The patent implements multi-functionality by integrating both ultrasonic mosquito repelling and electric mosquito repellent mat heating functions into a single device. The control circuit can switch between different working modes (ultrasonic mode, heating mode, and combined mode) to adapt to various use scenarios, thereby improving versatility without requiring multiple separate devices
Solution Approach 2:
The heating function is divided into multiple independently controllable heating sheets, each corresponding to a separate heating area on the PCB heating panel. This segmentation allows different heating areas to be independently activated based on the specific use scenario, providing flexibility while maintaining a unified device structure
2Reliability
If electric heating diffusion mode is used for mosquito repellent odor diffusion, then the device structure is simple, but the use effect is poor and user experience is poor
Solution Approach 1:
The patent merges the ultrasonic emission module with the electric mosquito repellent mat heating system. The ultrasonic vibrations are transmitted through the heating sheets, which simultaneously serve as both heating elements and ultrasonic transmission media. This combination enhances mosquito repelling effectiveness by integrating two different repelling mechanisms into a unified system
Solution Approach 2:
The control circuit dynamically adjusts the heating temperature and ultrasonic power parameters based on the selected working mode and environmental conditions. This parameter optimization ensures effective mosquito repelling while energy efficiency, improving reliability without requiring excessive system complexity
3Adaptability or versatility
If multiple heating sheets are used that can work independently, then the device can adapt to different space scenarios, but the control system complexity increases
Solution Approach 1:
The heating system is segmented into multiple independently controllable heating sheets, each with its own heating area on the PCB panel. The control circuit can selectively activate specific heating sheets based on the size and requirements of the space, providing adaptability without requiring a completely separate control system for each sheet
Solution Approach 2:
The control system dynamically adjusts which heating sheets are activated and at what power levels based on the detected space size and user preferences. This dynamic control allows the system to adapt to different scenarios (small room, large room, localized area) while maintaining a unified control interface, managing complexity through intelligent automation
