Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air exchanging devices require multiple installation holes for fans, leading to inconvenient construction and assembly, and lack an integrated air filter, necessitating additional purchases for air cleaning.
Innovation Solution
An air exchanging device with a housing containing two fan units and a single installation hole, featuring a compartment with through-holes for air circulation, integrated filters for purification, and a tube assembly with a divider for improved air guidance and heat exchange, allowing for easy installation and filter replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple fans are mounted to the wall for air exchange, then ventilation function is achieved, but multiple installation holes are required causing construction inconvenience and wall appearance defects
Solution Approach 1:
The patent combines multiple fan units (first fan unit and second fan unit) into a single integrated housing structure that requires only one installation hole in the wall. The housing contains multiple through-holes and channels that guide air flow from a single external opening to multiple internal fan units, thereby reducing the number of installation holes from multiple to one while maintaining the ventilation function of multiple fans.
2Adaptability or versatility
If conventional air exchanging device is used without integrated filter, then structure is simple, but additional air cleaner purchase is required
Solution Approach 1:
The patent integrates multiple functions into a single device: the housing contains not only fan units for air exchange but also filter units for air purification. The first filter unit and second filter unit are incorporated within the same housing structure, enabling the device to perform both ventilation and air cleaning functions simultaneously, eliminating the need for separate air cleaner equipment.
3Ease of operation
If filters are integrated in the air exchanging device, then air purification is achieved, but filter replacement convenience is reduced
Solution Approach 1:
The patent segments the housing into distinct compartments and uses detachable filter units (first filter unit and second filter unit) that can be independently removed and replaced. The filters are designed as separate modular components within the housing, allowing users to access and replace filters without disassembling the entire device, thereby maintaining ease of filter replacement despite the integrated multi-functional structure.
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 device achieves efficient air circulation between indoor and outdoor spaces with reduced installation complexity and enhanced filtration, providing improved ventilation and air quality while minimizing wall damage.
Implementation Method 1
During the operation of the first and second fan units, the external air can be guided from the second through-hole to the first air inlet of the first fan unit, and then is guided to the indoor space via the first air outlet of the first fan unit. Furthermore, the internal air can also be guided from the second air inlet to the second air outlet of the second fan unit, and then is guided to the outdoor space via the second through-hole.
