Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional fan assemblies are used to circulate air, then air circulation is achieved, but pathogens multiply and are circulated along with the air
Solution Approach 1:
The patent combines the air circulation function (fan assembly) with the pathogen elimination function (UV-C LED sterilization system) into a single integrated device. The UV-C LEDs are positioned around the fan assembly to sterilize air as it passes through, eliminating pathogens while circulating air simultaneously.
Solution Approach 2:
The patent introduces UV-C light as an intermediary substance that eliminates pathogens in the air stream. The UV-C LEDs emit light that interacts with pathogens as air passes through the fan assembly, destroying them without affecting the air circulation function.
2Productivity
If air purifying devices are made stationary to increase purification capacity, then large volume air purification is achieved, but portability and ease of installation are reduced
Solution Approach 1:
The patent employs a dynamic blade angle adjustment mechanism where the fan blades can change their angle of attack based on operational conditions. This allows the stationary device to optimize performance for different air flow requirements, effectively increasing purification capacity without requiring a larger physical structure that would compromise portability.
Solution Approach 2:
The device is divided into modular components including the fan assembly, UV-C LED ring, and adjustable blade mechanism. This segmentation allows for compact design that maintains high purification capacity while enabling easier assembly, disassembly, and potential portability.
3Reliability
If UV-C LEDs are integrated into the air purification assembly, then pathogen elimination capability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The ring-shaped UV-C LED assembly serves multiple functions: it sterilizes air passing through the fan assembly, provides structural support as part of the housing, and can be integrated with the blade adjustment mechanism. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity despite adding sterilization capability.
4Productivity
If blade angles are optimized for maximum airflow, then air circulation efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic blade angle adjustment that allows the fan blades to optimize their angle of attack based on real-time operational conditions. This dynamic adjustment enables the system to maintain high air circulation efficiency while consuming less energy, as the blades operate at optimal angles rather than fixed suboptimal angles.
Solution Approach 2:
The system changes the operational parameters of the fan blades by adjusting their angle dynamically. This parameter change allows the system to achieve maximum airflow efficiency at lower energy consumption levels, as the blades are always operating at their optimal angle rather than a fixed angle that may not be optimal for all conditions.

AI summary
A system and method for an air purification assembly that creates high volume, sterilized straight-line airflow with a significant reduction in electricity consumption utilizing counter rotation of two propellers mounted in reverse to create linear airflow and thrust that sucks in air through an inlet and blows the air out through an outlet. Air purification assembly may also sterilize the air as it passes through light utilizing a light core system with a ring-shaped assembly that has one or more UV-C LEDs that may kill bio-organisms within proximity to the air purification assembly while dissipating the heat created by the UVC LED lights in the light core system.
