Raised ATV Air Intake Routing for Sand and Water Exclusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing all-terrain vehicles face issues with foreign materials like sand particles and water entering the air intake, leading to frequent filter replacements and reduced power system lifespan due to contamination.
Innovation Solution
The design includes first and second air intake pipes with inlets positioned above the chassis and proximate to the steering assembly, reducing the likelihood of foreign material entry and enhancing airflow for improved engine combustion and transmission cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the air intake inlet is arranged adjacent to the engine and opened closer to the ground surface to shorten the air intake path, then the air intake path length is reduced, but foreign materials such as sand particles and water drops enter the air intake inlet more frequently
Solution Approach 1:
The patent extracts the air intake inlet from its conventional position adjacent to the engine and relocates it to the front portion of the vehicle near the steering assembly. This separation removes the harmful effect of ground-level foreign materials from the air intake system while maintaining efficient airflow to the engine through dedicated intake pipes.
Solution Approach 2:
The patent changes the spatial dimension of air intake by moving the inlet from a low, ground-proximate position to a high, front-portion position above the chassis. This dimensional change allows the vehicle to draw air from a cleaner zone away from sand and water while still achieving short intake paths through optimized pipe routing.
2Object-affected harmful factors
If the air filter is used to filter out foreign materials, then foreign materials are filtered, but frequent replacement of the air filter is troublesome
Solution Approach 1:
The patent extracts the air intake inlet from the engine vicinity and relocates it to the front portion of the vehicle. This extraction reduces the frequency at which the air filter becomes contaminated, thereby extending its service life and reducing replacement frequency while maintaining effective filtration.
Solution Approach 2:
The patent implements preliminary action by positioning the air intake inlet at a location that proactively prevents foreign material contamination before it reaches the air filter. This preventive positioning reduces the rate of filter degradation and minimizes maintenance intervals.
3Power
If foreign materials enter the power system, then the power performance is adversely affected, but the service life of the power system will also be shortened
Solution Approach 1:
The patent extracts the air intake inlet from proximity to the engine and power system components. This extraction prevents foreign materials from directly contaminating the power system, thereby protecting both power performance and extending service life by eliminating sand and water ingress.
Solution Approach 2:
The patent implements preliminary protection by positioning the air intake at a location that prevents foreign material entry before contamination can occur. This proactive measure safeguards the power system from abrasive wear and corrosion, maintaining power output and extending operational lifespan.
