Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan covers fail to effectively filter airflow and improve air quality by preventing dust buildup on fan blades while also diffusing pleasant scents, as they are often non-reusable and do not accommodate continuous operation without reducing airflow quality.
Innovation Solution
A fan cover with a flexible, breathable design that attaches to the air fan's inlet using an elastic band, featuring a mesh material and scent-modifying inserts to filter dust and diffuse fragrances into the airflow, ensuring improved air quality and scent diffusion without obstructing airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fan cover is attached to prevent dust buildup on fan blades, then air quality is improved, but airflow is reduced
Solution Approach 1:
The fan cover applies local quality by providing filtration only at the inlet area where dust accumulation occurs, while leaving the fan blades and outlet grille exposed. This localized approach allows dust prevention at the source without obstructing the overall airflow path through the fan.
Solution Approach 2:
The fan cover is segmented into multiple functional zones: a filtration zone at the inlet, an open zone over the fan blades, and an open zone at the outlet grille. This segmentation enables selective coverage that prevents dust buildup while maintaining airflow efficiency.
2Ease of operation
If a fan cover is designed to be left on during operation, then convenience is improved, but reusability and effectiveness are reduced
Solution Approach 1:
The fan cover utilizes a flexible mesh material that can be comfortably worn during operation while maintaining its filtration function. The flexible construction allows the cover to conform to the fan structure and remain securely attached without compromising breathability or filtration effectiveness.
Solution Approach 2:
The fan cover employs a mesh material with porous structure that allows air to pass through while trapping dust particles. This porous design enables continuous use during operation while maintaining effective filtration, preventing the cover from becoming clogged or ineffective over time.
3Object-affected harmful factors
If a fan cover filters airflow to improve air quality, then health is improved, but device complexity increases
Solution Approach 1:
The fan cover uses a simple porous mesh material that provides filtration functionality without complex mechanical structures. This straightforward porous design effectively filters dust from airflow while maintaining breathability and avoiding the complexity of adjustable mechanisms or multiple filtration stages.
Solution Approach 2:
The fan cover integrates multiple functions into a single simple structure: it acts as a dust filter, a breathable cover, and a comfortable wearable accessory. This multi-functionality is achieved through the mesh material's inherent properties rather than through complex mechanical systems.
4Object-affected harmful factors
If a fan cover is made from non-breathable material to block dust, then filtration is improved, but airflow is reduced
Solution Approach 1:
The fan cover employs a porous mesh material that allows air molecules to pass through while physically blocking larger dust particles. The porous structure creates numerous small openings that maintain open airflow paths while filtering out contaminants, thus preventing dust blockage without restricting air movement.
Solution Approach 2:
The mesh material provides local quality by offering dust filtration at the inlet area while maintaining open airflow characteristics throughout the rest of the fan structure. This localized filtration approach ensures that dust is blocked where it enters the system without impeding the overall airflow generation capability.

AI summary
A fan cover is an apparatus designed to prevent the buildup of dust and other particles on an air fan to improve the quality of air circulating through the air fan. To do so, the apparatus comprises a cover body, an elastic band, an insert-retaining pocket, and at least one scent-modifying insert. The cover body is designed to be attached onto the air inlet of the air fan to prevent the buildup of dust and other particles on the air fan. The elastic band facilitates the secure attachment of the cover body to the air fan so that the cover body stays attached to the air fan during operation of the air fan. The insert-retaining pocket is designed to receive the at least one scent-modifying insert without obstructing the airflow through the air fan. The at least one scent-modifying insert allows the diffusion of scents and/or fragrances into the airflow.
