Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional air purifier designs are used, then air purification function is provided, but the device size is too large to fit seamlessly into modular wall systems
Solution Approach 1:
The patent transitions from conventional bulky three-dimensional air purifier designs to a slim, low-profile configuration that prioritizes reduction in one dimension (depth/thickness) while maintaining functional volume. This dimensional reconfiguration enables integration into modular wall sections and space-constrained environments without sacrificing air purification capability.
Solution Approach 2:
The air purifier is designed to be nested within modular wall sections or recessed mounting spaces. The compact housing allows the device to be concealed within wall cavities or mounted in tight spaces, making the air purification system an integrated part of the architectural structure rather than a separate bulk device.
2Length of stationary object
If the air purifier profile is reduced to fit wall systems, then integration capability improves, but airflow capacity may be compromised
Solution Approach 1:
The patent employs variable speed fans and adjustable airflow settings that allow the compact device to dynamically optimize air movement. The motorized fan system can increase rotational speed to compensate for the reduced physical size, maintaining adequate airflow capacity despite the slim profile constraint.
Solution Approach 2:
The invention changes key operational parameters including fan rotation speed, motor power output, and potentially filter surface area density to compensate for the reduced housing volume. These parameter adjustments ensure that the compact design maintains sufficient airflow capacity and air change rates for effective air purification.
3Volume of moving object
If a slim profile design is used, then space efficiency and aesthetic integration improve, but device complexity increases
Solution Approach 1:
The air purifier employs modular filter assemblies and segmented internal components that can be independently arranged within the compact housing. This segmentation allows for efficient space utilization and simplifies maintenance, as filters and other components can be accessed and replaced without disassembling the entire device.
Solution Approach 2:
The patent combines multiple functions into integrated components - for example, the motor housing also serves as structural support, the filter assembly integrates with the airflow path housing, and control electronics are embedded within existing structural elements. This merging reduces the number of separate parts and simplifies the overall device architecture despite the compact size.

AI summary
A low-profile air purifier comprises a housing that includes a pair of plates opposing one another, an intake opening and an output opening; a toroidal fan rotatably mounted in the housing between the plates, an axis of the toroidal fan being essentially perpendicular to the plates; a motor disposed in a central opening of the toroidal fan for rotating the toroidal fan; and a filter mounted to the housing for filtering air flowing through the housing. The present patent application also discloses a modular wall section that comprises an internal frame; an air purifier mounted within the internal frame; and a panel mounted in the internal frame for movement between an open position for accessing the air purifier and a closed position concealing the air purifier. The air purifier of the modular wall section may have similar configuration as the above discussed low-profile air purifier.
