Problem
Existing air cleaners face issues with blocked airflow paths due to stepper motors, vibration, complex disassembly for maintenance, and inefficient air circulation, leading to reduced cleaning performance and increased noise.
Innovation Solution
An air cleaner design with a removably mounted booster module, utilizing a sirocco fan and outer rotor motor to enhance airflow circulation without blocking the inner path, and a contact power supply for easy maintenance, reducing vibration and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a stepper motor is disposed in the flow path to rotate the circulator, then the circulator can be rotated to extend airflow distance, but the motor blocks a portion of the flow path area, deteriorating air cleaning performance
Solution Approach 1:
The motor is extracted from the flow path and relocated to the booster neck, which is positioned outside the main airflow channel. This allows the circulator to be rotated for extending airflow distance while the motor does not block the flow path, thus maintaining air cleaning performance.
2Reliability
If the circulator is coupled to the main body by screws, then the circulator can be securely mounted, but it becomes complicated to separate the circulator for maintenance
Solution Approach 1:
The circulator assembly is segmented into a modular booster module that includes the circulator, motor, and housing as an integrated unit. This module can be easily detached from the main body without requiring separation of individual components, thus maintaining secure mounting during operation while enabling simple maintenance by removing the entire module.
3Adaptability or versatility
If a separate fan is disposed at the upper portion to regulate air discharge direction, then filtered air can be guided to flow in all directions, but the device complexity increases
Solution Approach 1:
The circulator's rotation function and the fan's air discharge function are merged into a single integrated circulator assembly. The circulator rotates to change the discharge direction of filtered air, eliminating the need for a separate direction-regulating fan and reducing overall device complexity while maintaining versatile air distribution capability.
