Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intake systems are prone to damage and engine issues due to moisture ingress, especially in tropical regions with high precipitation, and have complex configurations that increase manufacturing costs and man-hours.
Innovation Solution
An integrated intake system design where the intake duct and air cleaner are formed together, with a 'U'-shaped air movement path and additional resonators to prevent moisture and noise, featuring drain valves and a simplified configuration to enhance fording ability and reduce costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the intake duct and air cleaner are formed separately and connected, then the system allows modular assembly, but the manufacturing complexity and man-hours increase
Solution Approach 1:
The intake duct and air cleaner are merged into a single integrated component called the air cleaner body assembly. The intake duct portion is formed as an integral part of the air cleaner body, eliminating the need for separate connection interfaces, gaskets, and fastening operations. This merging directly reduces manufacturing complexity and assembly man-hours while maintaining the functional separation of air intake and filtration.
2Reliability
If moisture prevention features are added to the intake system, then the protection against moisture ingress improves, but the device complexity increases
Solution Approach 1:
The air movement path is designed with a curved configuration where the air inlet and filter are positioned above the connection portion between the intake duct and air cleaner body. This curved path utilizes gravity and flow dynamics to prevent moisture accumulation and ingress into the air cleaner, providing reliable moisture protection through geometric design rather than additional mechanical components.
Solution Approach 2:
The intake shield is positioned at the air inlet to preemptively block moisture and large impurities before they can enter the intake duct. This preliminary protective action prevents moisture ingress at the source, eliminating the need for complex sealing systems or moisture traps downstream in the intake path.
3Object-affected harmful factors
If an intake shield is added to prevent moisture and impurities, then the protection capability improves, but the device complexity increases
Solution Approach 1:
The air cleaner body assembly serves multiple functions: it acts as both the air cleaner housing and the intake duct, provides structural support for the filter, creates the curved air movement path for moisture prevention, and integrates the connection interface for the intake hose. This multi-functionality reduces the need for separate protective components like intake shields, as the integrated structure itself provides the necessary protection against moisture and impurities.

Function Achieved in This Case
Effectively prevents moisture from reaching the engine, reduces manufacturing complexity and costs, and enhances vehicle fording ability in tropical regions by integrating components and using resonators to manage noise and moisture.
Implementation Method 1
the intake duct portion may be provided with a first internal resonator portion that is formed to expand a space thereof by being connected to the intake duct portion. Furthermore, the air cleaner body portion may be provided with a second internal resonator portion which is for reducing noise

AI summary
An intake system of a vehicle is configured so that air moves along a ‘U’-shaped movement path from an entrance of an intake duct portion into which outside air is introduced to a position where a filter is mounted, and is configured so that the intake duct portion, an air cleaner body portion, and an external resonator are formed integrally with each other.
