Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtration systems for removing particulates are expensive due to the need for regular maintenance and costly filter media, and they may not be necessary for applications where only air purification is required without contaminant collection.
Innovation Solution
An air-cleaning blower system that uses centrifugal and centripetal forces within a housing to separate particulates from air or gas without filtration media, utilizing an impeller to create pressure zones for efficient separation and ejection of heavier particulates, while allowing lighter air to pass through for purification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If filtration systems are used to capture particulates, then air purification is achieved, but maintenance costs and operational expenses increase due to regular filter replacement
Solution Approach 1:
The patent removes the filter media component from the air cleaning system entirely. Instead of using filters to capture particulates, the system extracts only the necessary function of air purification by allowing cleaned air to pass through while ejecting particulates through a separate debris discharge mechanism, eliminating the need for filter replacement and maintenance.
Solution Approach 2:
The air cleaning system performs self-maintenance by automatically ejecting collected particulates through the debris discharge channel. The impeller continuously removes accumulated debris without requiring human intervention for filter changes, making the system self-sustaining and eliminating routine maintenance tasks.
2Object-affected harmful factors
If filtration systems are used to capture particulates, then air purification is achieved, but the cost of filter media and replacement increases operational expenses
Solution Approach 1:
The patent eliminates the filter media component from the system, extracting only the essential air purification function. By using an impeller-based separation mechanism, the system removes particulates without requiring expensive filter materials, thereby eliminating ongoing costs associated with filter media purchase and replacement.
Solution Approach 2:
Instead of using expensive, replaceable filter media, the patent employs a durable, reusable impeller mechanism that separates particulates through mechanical action. This approach replaces costly disposable filters with a permanent, low-cost mechanical system that has no consumable parts.
3Object-affected harmful factors
If filtration systems are used, then particulates are captured, but the system complexity increases due to filter installation and removal requirements
Solution Approach 1:
The patent removes the filter installation and removal infrastructure from the system. By using an integrated impeller and debris discharge channel, the system achieves particulate capture without requiring separate filter components, simplifying the overall device structure and eliminating the complexity of filter installation, removal, and disposal procedures.
4Productivity
If centrifugal force is used to separate particulates, then air purification efficiency is improved, but energy consumption increases due to high-speed impeller operation
Solution Approach 1:
The patent optimizes the impeller rotation speed to achieve effective particulate separation at moderate velocities. By carefully selecting and adjusting operational parameters such as rotational speed, the system achieves high air cleaning efficiency without excessive energy consumption, balancing productivity with energy efficiency.

AI summary
Disclosed is an air-cleaning blower (“ACB”) that includes an inlet cover, housing, clean-side cover, and impeller. The inlet cover may be a rigid flat surface with a central opening. The housing may have a hollow inner cavity and walls that form an incomplete cylinder with a slit between the walls. The clean-side cover may be a rigid flat surface with apertures, and with brackets extending between the apertures to connect an impeller/motor mount to the clean-side cover. The impeller may be mounted on the impeller/motor mount inside the housing between the inlet cover and the clean-side cover. The impeller rotates to induce suction of particulate-pervaded air or gas through the central opening, to circulate the heavier particulates against an interior of the walls until ejection through the slit, and to circulate the lighter cleaned air or gas in front of the heavier particulates until ejection through the apertures.
