External Dust Charging Layout for Compact Air Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning apparatuses suffer from reduced air cleaning performance and increased size due to the placement of the ionizing part, which acts as flow resistance and occupies valuable space, leading to inefficient air filtration.
Innovation Solution
An air conditioning apparatus with an electric charge device positioned outside the main body to charge dust particles, coupled with a filter device using dielectric barrier discharge for dust collection and a power source that applies different frequencies for cleaning, allowing for enhanced air filtration without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the ionizing part is disposed at a rear side of a suction part, then the air conditioning apparatus can be compact, but air cleaning performance deteriorates and flow resistance increases
Solution Approach 1:
The ionizing part is extracted from the main body of the air conditioning apparatus and disposed outside. This separation allows the ionizing part to be positioned in an optimal location for air cleaning performance without compromising the compactness of the main apparatus body, thereby resolving the contradiction between apparatus size and air cleaning performance.
Solution Approach 2:
The ionizing part is disposed in a different spatial dimension (outside the main body) rather than within the internal space. This dimensional repositioning eliminates the space occupancy conflict while maintaining effective air treatment, allowing both compact apparatus design and high air cleaning performance to coexist.
2Device complexity
If the ionizing part is disposed at a rear side of a suction part, then the apparatus structure is simplified, but flow resistance against air increases
Solution Approach 1:
The ionizing part is extracted from the air flow path within the main body and positioned outside. This eliminates the flow resistance that would be generated if the ionizing part were placed in the rear side of the suction part, while the overall structural complexity remains manageable due to the straightforward external coupling design.
3Productivity
If the ionizing part increases in size, then air cleaning performance improves, but the air conditioning apparatus increases in size
Solution Approach 1:
The ionizing part is extracted from the main body and disposed outside, allowing it to be sized optimally for air cleaning performance without being constrained by the space available within the apparatus. This separation enables the ionizing part to increase in size for better performance while the main apparatus body remains compact.
Solution Approach 2:
By positioning the ionizing part in an external dimension rather than within the internal volume of the apparatus, the patent allows the ionizing part to achieve the necessary size for high air cleaning performance without increasing the footprint or volume of the main air conditioning apparatus body.
