Air Purifier Housing With Switchable Dust and Clean Inlets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifiers face challenges in effectively removing dust from the environment around them, leading to potential pollution and reduced filter lifespan, and often require multiple units to perform both dust suction and air purification functions, increasing volume and power consumption.
Innovation Solution
An air purifier design featuring a housing with a clean inlet part and a dust inlet part, where the dust inlet part is located lower and extends in the width direction, allowing for intense suction of dust from the floor surface, and a flow passage forming unit that directs external air and dust into the air purification unit, enabling efficient dust collection and air purification with a single fan member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single air purifier unit is used for both dust suction and air purification, then device complexity is reduced, but it becomes difficult to independently control dust flow passage and air purification flow passage
Solution Approach 1:
The housing is divided into distinct dust suction flow passage and air purification flow passage regions, with separate inlet ports and independent control mechanisms for each function, allowing a single unit to perform both functions without operational interference
Solution Approach 2:
The dust cover can be moved between a first position (allowing dust suction) and a second position (blocking dust suction), enabling dynamic switching between dust removal mode and air purification mode within a single device
2Productivity
If the air intake port is always open to allow air flow, then air purification function is maintained, but dust is easily introduced into the device
Solution Approach 1:
The dust cover provides dynamic control over the dust suction inlet, allowing it to be opened when dust removal is needed and closed when only air purification is required, preventing dust contamination while maintaining air purification capability
Solution Approach 2:
The dust cover can be completely removed from the housing, allowing direct access for vacuum cleaner nozzle to suction dust from the housing interior without restricting air purification flow
3Productivity
If dust suction inlet is positioned at the top, then dust suction function is achieved, but dust remaining on the floor cannot be effectively collected
Solution Approach 1:
The dust suction inlet is repositioned from the top surface to the lower side surface of the housing, closer to the floor level, enabling effective collection of dust that settles on the floor surface while maintaining the dust suction function
4Adaptability or versatility
If multiple cubes are used to perform both dust suction and air purification functions, then functional versatility is achieved, but volume is inevitably increased
Solution Approach 1:
The air purifier housing integrates both dust suction flow passage and air purification flow passage systems into a single unit, combining multiple functions that would traditionally require separate devices into one compact system
Solution Approach 2:
The housing serves multiple functions simultaneously: it acts as the main body for air purification, provides dust suction capability through dedicated flow passages, and offers dust collection storage space, making a single device universally applicable for both air cleaning and dust removal tasks
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
The design effectively removes dust from the environment, improves power efficiency by using a single fan member for both functions, and allows for easy collection of dust through a removable tray, enhancing the air purifier's cleaning effectiveness and operational efficiency.
Implementation Method 1
