Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air boxes and filters in vehicles experience restricted air flow due to particulate buildup, leading to decreased engine performance and fuel economy, and often result in contaminants being drawn into the engine, with discarded filters contributing to landfill waste.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional air filter is used, then particulate matter is removed from air, but air flow becomes restricted as the filter clogs
Solution Approach 1:
The air filter is divided into multiple independent filtration elements (first air filtration element, second air filtration element, third air filtration element) that can be separately accessed and replaced. This segmentation allows maintenance of one element without affecting the others, maintaining air flow productivity while ensuring continuous filtration reliability.
Solution Approach 2:
The patent implements a reusable air filter system where filtration elements can be removed, cleaned, and reused multiple times. This eliminates the need to discard the entire filter assembly when one element clogs, recovering the value of unused filtration elements and maintaining air flow without restriction.
2Device complexity
If a single air inlet is used, then the air box structure is simplified, but air flow capacity is limited
Solution Approach 1:
The air box is segmented into multiple inlet ports (first air inlet, second air inlet, third air inlet) that can be independently configured. This allows the system to maintain a relatively simple overall structure while providing multiple air flow paths that increase total air flow capacity to match different engine requirements.
Solution Approach 2:
The air box is designed with multiple inlet ports that can accommodate different filter configurations and engine types. The same air box structure can serve multiple functions and adapt to various applications, maintaining structural simplicity while providing the flexibility needed for different air flow demands.
3Reliability
If paper filters are discarded after use, then contamination protection is ensured, but landfill waste increases
Solution Approach 1:
The filtration elements are designed to be removable and reusable. Instead of discarding the entire filter assembly when one element becomes contaminated, the used element can be removed and replaced while the clean elements remain in service. This dramatically reduces waste while maintaining engine protection, as only the contaminated portion needs replacement.
Solution Approach 2:
The patent transitions from disposable paper filters to reusable filtration elements that can undergo cleaning and regeneration processes. This parameter change from single-use to multi-use extends the service life of filtration media, reducing the frequency of disposal and the associated environmental waste.
4Adaptability or versatility
If tortuous ductwork is used to deliver air to the engine, then the air box can be positioned flexibly, but air flow restriction increases
Solution Approach 1:
The air delivery system is segmented into multiple independent inlet ports and separate ductwork paths. This allows different portions of the system to be optimized independently - the air box can be positioned flexibly to accommodate spatial constraints while each inlet path can be designed for optimal air flow with minimal restriction.
Solution Approach 2:
The patent utilizes three-dimensional space more efficiently by providing multiple inlet ports at different locations and orientations. This dimensional approach allows air to enter from multiple directions, reducing the need for long, tortuous ductwork paths and minimizing air flow restriction while maintaining positioning flexibility.

AI summary
An apparatus and a method are provided for a multiple inlet air box to communicate an airstream through an air filter (124) to an air intake duct of an internal combustion engine of a vehicle. The multiple inlet air box is comprised of a housing (108) that supports the air filter within an interior of the housing. A mount portion within the housing fixedly receives a base of the air filter. Multiple air inlets (104) couple with corresponding air inlet ports (168) of the vehicle to direct the airstream into the multiple inlet air box. A duct (112) directs the airstream from the multiple air inlets to the interior of the housing. A conduit (128) communicates the airstream from an interior of the air filter to the air intake duct of the internal combustion engine.
