Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners have limited capacity and reliability, with reduced suction capacity due to structural resistance and limited air flow direction, resulting in incomplete air purification in indoor spaces, requiring user movement to achieve desired air purification.
Innovation Solution
The air cleaner design incorporates dual blowing devices with cylindrical cases and 360-degree suction ports, along with a flow adjusting device that allows air to be suctioned and discharged in multiple directions, enhancing suction capacity and air flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the blowing amount of the fan is increased to improve air purification performance, then the purification capacity is improved, but noise generated by the fan increases and reliability decreases
Solution Approach 1:
The patent divides the blowing function into multiple fans (first blowing fan and second blowing fan) positioned at different locations. This segmentation allows the system to achieve high total airflow without requiring any single fan to operate at high noise-generating speeds, thus maintaining reliability while improving overall purification capacity.
Solution Approach 2:
The patent transitions from single-direction upward discharge to multi-directional discharge by adding a lateral discharge port and positioning fans at different orientations. This dimensional change in airflow distribution improves air purification effectiveness throughout the space without requiring increased fan blowing amount, thereby avoiding noise and reliability issues.
2Ease of manufacture
If a rectangular parallelepiped case is used with limited suction ports, then manufacturing is simplified, but suction capacity is reduced due to structural resistance
Solution Approach 1:
The patent segments the air suction function across multiple surfaces of the case (front surface, rear surface, and side surfaces) rather than relying on a single suction port. This maintains the simple rectangular case structure for ease of manufacture while dramatically increasing suction capacity by distributing intake across multiple locations, reducing localized structural resistance.
Solution Approach 2:
The patent adds suction ports on lateral surfaces in addition to front and rear surfaces, transitioning from limited directional suction to omnidirectional or multi-dimensional suction. This maintains the simple rectangular geometry while vastly improving suction capacity by utilizing air intake from all directions around the device.
3Device complexity
If air is discharged in only one upward direction, then the device structure is simplified, but air cleaning function is limited as purified air does not reach distant spaces
Solution Approach 1:
The patent segments the air discharge function into multiple discharge ports (upper discharge port and lateral discharge port) with different orientations. This maintains relatively simple device structure while enabling purified air to be distributed in multiple directions, significantly expanding the air cleaning coverage to reach distant and lateral spaces.
Solution Approach 2:
The patent transitions from single vertical discharge to multi-directional discharge by adding lateral discharge capability. This allows purified air to distribute not only upward but also laterally throughout the space, dramatically improving air cleaning coverage without substantially increasing device complexity.
4Device complexity
If the air cleaner is moved by user to purify different spaces, then device structure is simplified, but ease of operation is reduced and time is consumed
Solution Approach 1:
The patent enables the air cleaner to effectively purify air in all directions around it through multi-directional suction and discharge capabilities. This creates a stationary device that can clean the entire surrounding space without requiring user movement, significantly improving ease of operation while maintaining simple device structure.
