Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers lack the ability to adapt their suction modes based on the surrounding environment, leading to inefficient air purification due to varying obstructions and resistance.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the air purifier uses a fixed suction mode, then the device complexity is reduced, but the adaptability to surrounding environment deteriorates
Solution Approach 1:
The patent implements dynamic blade angle adjustment where the blades can change their orientation based on detected environmental conditions. The blade assembly includes multiple blades that can rotate independently to optimize airflow direction, transforming a static structure into a dynamic one that adapts to varying surroundings.
Solution Approach 2:
The system incorporates sensors that detect environmental parameters such as air quality, temperature, and humidity, and this information is fed back to the control unit which automatically adjusts the blade angles and fan speed accordingly, creating a closed-loop feedback system that enhances adaptability without requiring manual intervention.
2Productivity
If the air purifier operates at high fan speed continuously, then the air purification efficiency is improved, but the power consumption increases
Solution Approach 1:
The fan operates dynamically with variable speed control based on real-time environmental conditions. The control unit adjusts fan speed between low, medium, and high levels according to air quality measurements, allowing the system to maintain high purification efficiency when needed while reducing power consumption during periods of acceptable air quality.
Solution Approach 2:
The system changes operational parameters (fan speed, blade angle) based on detected environmental conditions. When air quality deteriorates, the fan speed parameter is increased to enhance purification; when air quality is acceptable, the parameter is reduced to save energy, creating an adaptive power management strategy.
3Productivity
If the blades are positioned to maximize airflow in one direction, then the air suction efficiency in that direction is improved, but the versatility to handle obstructions from different directions deteriorates
Solution Approach 1:
The blade assembly is segmented into multiple independent blades that can be positioned at different angles. This segmentation allows each blade to be optimized for specific airflow directions, and the combination of blades provides comprehensive coverage for handling obstructions from various directions simultaneously.
Solution Approach 2:
The blades are designed to rotate and adjust their angles dynamically based on detected obstruction patterns and airflow conditions. This dynamic repositioning capability allows the system to optimize airflow efficiency for current conditions while maintaining versatility to adapt to changing obstruction scenarios.
