Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air intake assemblies for internal combustion engines either lack efficiency in separating intake air from other air in the engine compartment or complicate installation and maintenance, with open-element filter housings being easy to install but inefficient and sealed filter housings being difficult to maintain.
Innovation Solution
An air intake assembly featuring a sealed filter housing with a multi-component coupling interface that securely connects the air filter and intake tube without fastening hardware, using a clearance engineering fit to simplify installation and maintenance, and includes features like a hump coupler and clamps for easy integration with engine components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an open-element filter housing is used to separate intake air from other air in the engine compartment, then ease of installation and maintenance is improved, but isolation efficiency of the air filter from engine compartment air deteriorates
Solution Approach 1:
The filter housing is divided into multiple segments or sections that can be easily assembled and disassembled. This segmentation allows for simple installation and maintenance while maintaining effective isolation when properly assembled, resolving the contradiction between ease of operation and isolation efficiency.
Solution Approach 2:
The air filter element is nested within the filter housing structure, and the housing itself may be nested within the engine compartment air intake system. This nesting arrangement ensures that the filter remains isolated from unfiltered air while allowing for relatively simple access and maintenance through the nested structure.
2Reliability
If a sealed filter housing is used to isolate the air filter from engine compartment air, then isolation efficiency is improved, but ease of installation and maintenance deteriorates
Solution Approach 1:
The sealed filter housing is segmented into sections that can be separately assembled and maintained. This segmentation maintains the sealed isolation properties while enabling easier installation and maintenance compared to a completely monolithic sealed structure.
Solution Approach 2:
The filter housing incorporates dynamic access mechanisms or removable sections that allow the sealed structure to be temporarily opened for maintenance while maintaining seals during normal operation. This dynamic capability resolves the contradiction between maintaining sealed isolation and enabling easy maintenance.
3Reliability
If traditional fastening hardware is used to connect the air filter and intake tube, then connection security is improved, but device complexity and part count increase
Solution Approach 1:
The connection interface between the air filter and intake tube is merged into a unified coupling structure that integrates the sealing and securing functions. This single integrated coupling mechanism eliminates the need for separate fastening hardware while maintaining secure connections, resolving the contradiction between connection security and device complexity.
Solution Approach 2:
The coupling interface is designed with universal multi-functionality, serving both as a structural connector and a sealing element. This multi-functional design replaces traditional multi-component fastening systems with a single component that performs multiple functions, reducing part count while ensuring secure connections.
4Ease of operation
If a multi-component coupling interface with clearance engineering fit is used to connect the air filter and intake tube, then ease of installation is improved, but connection precision requirements increase
Solution Approach 1:
The coupling interface utilizes controlled clearance parameters that are optimized for both ease of assembly and manufacturing feasibility. By carefully selecting and standardizing clearance values, the design achieves simple installation while maintaining manufacturability, resolving the contradiction between ease of operation and manufacturing precision requirements.
