Integrated Air Purifier Airflow Path to Prevent Clean-Air Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifying devices combined with electric fans mix purified and non-purified air, degrading air cleanliness and increasing power consumption due to separate engines for each unit.
Innovation Solution
An air purifying device design that includes a purifying apparatus, an air supply apparatus, an air guide apparatus, and an air flow driving apparatus, where the air guide apparatus directs purified air from the purifying apparatus to the air supply apparatus, preventing non-purified air from entering and enhancing air supply quality, while using a single air flow driving apparatus to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If air purifying device and electric fan are combined separately with independent engines, then each unit can function independently, but power consumption increases and production cost increases
Solution Approach 1:
The patent combines the air purifying device and electric fan into a single integrated device where the fan motor serves dual purposes: driving the fan blades for air circulation and simultaneously driving the impeller for air purification. This merging eliminates the need for a separate purification engine, reducing power consumption while maintaining both functions.
Solution Approach 2:
The fan motor is designed to perform multiple functions: it acts as both the driving force for the fan blades and the purification impeller. This multi-functionality allows the single motor to replace what would traditionally require two separate motors, thereby reducing energy consumption and production costs while preserving independent operational capability.
2Adaptability or versatility
If air purifying device and electric fan are combined separately with independent engines, then each unit can function independently, but production cost increases
Solution Approach 1:
The patent merges the air purifying device and electric fan into one integrated unit with a shared fan motor. This consolidation reduces the number of components that need to be manufactured and assembled, thereby lowering production costs while maintaining the capability for both air purification and fan functions to operate independently when needed.
Solution Approach 2:
By designing the fan motor to serve dual purposes (driving both fan blades and purification impeller), the patent reduces the total component count. This multi-functional design simplifies the manufacturing process and reduces production costs while preserving the adaptability of the system to perform either function independently.
3Productivity
If purified air is blown out through electric fan, then air supply quantity increases, but purified air mixes with non-purified air degrading air cleanliness
Solution Approach 1:
The patent introduces a guide component as an intermediary structure between the purification cavity and the fan. This guide component creates a dedicated airflow channel that directs purified air from the purification cavity through the fan outlet without allowing mixing with non-purified air from the external environment, thereby maintaining air cleanliness while preserving increased air supply quantity.
Solution Approach 2:
The patent segments the airflow paths by creating distinct channels: one for purified air flow from the purification cavity through the guide component, and another for ambient air intake. This segmentation prevents mixing between purified and non-purified air streams, ensuring that the high-volume air supply maintained by the fan does not compromise air cleanliness.
