Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing oil fume purifiers use multiple filter components and complex control systems, then purification effectiveness is improved, but device complexity and size increase
Solution Approach 1:
The patent combines multiple purification functions (electrostatic filtration, activated carbon adsorption, and ozone generation) into a single integrated purifier unit. The electrostatic filter, activated carbon element, and coil assembly are housed together in one device, eliminating the need for separate purification devices and reducing overall system complexity while maintaining comprehensive purification effectiveness.
Solution Approach 2:
The purifier is designed to perform multiple purification functions simultaneously: the electrostatic filter captures particles, the activated carbon element adsorbs odors and gases, and the coil assembly generates ozone for sterilization. This multi-functional design allows a single device to replace multiple specialized devices, reducing complexity while improving overall purification reliability.
2Reliability
If existing oil fume purifiers include multiple components and systems, then purification performance is improved, but the size of the device increases
Solution Approach 1:
The patent employs a nested arrangement where the electrostatic filter, activated carbon element, and coil assembly are positioned concentrically or in overlapping configurations within the housing. The electrostatic filter is arranged around the coil assembly, and the activated carbon element is positioned to utilize the same air flow path, maximizing space utilization and minimizing device volume while maintaining all purification functions.
Solution Approach 2:
The purifier utilizes vertical stacking and multi-level arrangement of components within the housing. The electrostatic filter, activated carbon element, and coil assembly are arranged at different vertical levels and radial positions, allowing three-dimensional space optimization. This dimensional arrangement enables all components to fit within a compact cylindrical housing while maintaining effective air flow through each purification stage.
3Reliability
If the purifier uses ozone generation for sterilization, then purification effectiveness is improved, but energy consumption increases
Solution Approach 1:
The coil assembly operates in periodic cycles rather than continuously, generating ozone during designated sterilization periods and remaining inactive during normal filtration operation. The controller activates the coil assembly at intervals to maintain sterilization effectiveness while minimizing energy consumption during routine air purification when full sterilization is not required.
Solution Approach 2:
The controller adjusts the operating parameters of the coil assembly based on air quality conditions, activating ozone generation only when pollution levels exceed thresholds or during scheduled sterilization cycles. This parameter-based control allows the system to maintain sterilization effectiveness when needed while reducing energy consumption during normal operating conditions.

AI summary
Disclosed are a purifier and an extractor hood. The purifier includes a shell and a purification assembly. A receiving space is formed in the house, and the purification assembly is arranged in the receiving space. The purification assembly includes a support part, a coil assembly, a grille part and a power supply assembly. The coil assembly is arranged on one side of the support part, and the grille part is connected to the support part. The grille part and the support part form a mounting chamber in which an activated carbon element is placed. The power supply assembly is arranged on one side of the support part facing away from the coil assembly, and the power supply assembly is electrically connected to the coil assembly. The extractor hood includes the purifier and a fan connected to the purifier. The fan is configured for the suction of gas and discharging the gas into the purifier, and a second plug of the purifier is connected to the fan. Through the arrangement of the purification assembly, the purifier can purify oil fumes to make the gas discharged from the purifier cleaner. The purification assembly is arranged in the receiving space of the shell, so that the structure of the purifier is simple and the production of the miniaturized purifier is facilitated.
