Innovation Solution
An air purifier design featuring a columnar hollow filter with an integrated impurity scraping member and accommodation member, driven by a fan and a driving member, which scrapes and stores impurities within an accommodation chamber, reducing the need for frequent filter element cleaning or replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional filter element is used in an air purifier, then filtration function is provided, but pet hair and dust accumulate on the surface reducing filtration capacity and requiring frequent user cleaning
Solution Approach 1:
The filter element is designed with self-cleaning functionality through an impurity scraping member that automatically removes accumulated pet hair and dust from the filter surface. The scraping member includes a scraping portion that contacts the filter outer surface and an impurity collection chamber that stores removed impurities, enabling the filter to maintain its filtration capacity without frequent user intervention for cleaning.
Solution Approach 2:
The system automatically discards accumulated impurities by collecting them in the impurity collection chamber. The collection chamber has a detachable structure that allows users to easily remove and empty the collected impurities, transforming the manual cleaning task into a simple periodic emptying operation that significantly reduces maintenance frequency.
2Loss of time
If filter surface is left uncleaned, then user maintenance time is reduced, but filtration capacity decreases due to clogged air inlets
Solution Approach 1:
The filter element performs self-maintenance by automatically scraping off accumulated impurities during or after filtration operation. The scraping member continuously or periodically removes pet hair and dust from the filter surface, preventing air inlet clogging and maintaining optimal filtration capacity without requiring user time for cleaning.
Solution Approach 2:
The impurity collection chamber is designed to collect and store removed impurities during the filtration process, preparing them for easy periodic removal. This preliminary collection action prevents impurity accumulation on the filter surface while minimizing the time users need to spend on maintenance, as they only need to periodically empty the pre-collected impurities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances filtration quality by automatically removing impurities, such as pet hair, from the filter surface, thereby improving user experience by reducing maintenance frequency and maintaining efficient air purification.
Implementation Method 1
Through various technical means such as filtration and adsorption, the air purifier can effectively remove visible contaminants from air
Implementation Method 2
A surface of a filter element of the air purifier is prone to adsorb pet hair and dust

AI summary
An air purifier comprises: a columnar hollow filter, a fan, an impurity scraping member and an impurity accommodation member. The fan starts and then draws external air through a sidewall of the columnar hollow filter into its cavity, the air is filtered and purified as it passes through the columnar hollow filter, thereby discharging clean air. Impurities attached to the air are accumulated on a surface of the columnar hollow filter; when the impurities accumulated on the surface of the columnar hollow filter reach a certain amount, the columnar hollow filter moves relative to the impurity scraping member, the impurity scraping member scrapes off the impurities from the surface of the columnar hollow filter into an accommodation chamber of the impurity accommodation member. The impurity accommodation member can temporarily store the impurities, thereby improve filtration quality of the air purifier and reduce replacement frequency of the filter element.
