Fender-Accessible Air Filter for Work Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air filter systems for work machines, such as those described in U.S. Pat. No. 5,833,528, occupy valuable space within the cabin, are complex, and draw in excessive dust and debris, making servicing difficult and inefficient.
Innovation Solution
An air induction system with an air filter located within a work machine's fender, accessible from outside, featuring a conduit and a hinged cover for easy access, which reduces dust intake and conserves cabin space by drawing air from above the cabin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air filter is placed inside the operator cabin for easy servicing, then the filter is accessible for maintenance, but it occupies valuable space within the cabin
Solution Approach 1:
The air filter is extracted from the operator cabin interior and relocated to the exterior, specifically to the fender area. This allows the filter to be serviced from outside the cabin while freeing up valuable interior space, directly resolving the contradiction between accessibility and space occupation.
2Ease of operation
If the air filter is accessed from inside the cabin, then servicing is straightforward, but it draws air from a point prone to excessive dust and debris
Solution Approach 1:
The air intake location is extracted from the cabin interior and repositioned to the fender area above the cabin. This location draws air from a cleaner source away from dust-generating operations, while the filter remains externally accessible through the fender opening.
Solution Approach 2:
The fender structure serves as an intermediary element that houses the air filter and intake system externally. This intermediary location provides both protected access to the filter and a favorable position for clean air intake, mediating between accessibility requirements and air quality needs.
3Ease of operation
If a complex air filter arrangement is used to provide external access, then the filter is accessible from outside the cabin, but the system becomes too complicated
Solution Approach 1:
The air filter housing is merged with the existing fender structure, eliminating the need for separate access mechanisms. The fender opening and cover serve dual purposes as both structural elements and filter access points, simplifying the overall system while maintaining external accessibility.
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 solution provides easier and faster filter servicing, reduces dust and debris intake, and maintains a cleaner cabin environment by minimizing space usage and simplifying maintenance, while drawing cleaner air due to its location away from dust-prone areas.
Implementation Method 1
The air filter is disposed within the at least one fender and accessible from outside of the work machine. The air filter is fluidly connected to and disposed downstream of the air inlet flow member.
