Vehicle Filter Holder Vibration for Self-Cleaning Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle filters, particularly in dusty or polluted environments, become clogged with particles over time, leading to frequent maintenance, downtime, and additional costs, with high-filter-class systems risking damage during cleaning.
Innovation Solution
A filter device with a movable holder and filter medium that allows for a relative movement between the holder and a component, utilizing a stop to induce vibration and dislodge particles, eliminating the need for additional energy sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter medium is cleaned by conventional methods, then particles are removed from the filter, but the filter medium may be damaged or destroyed
Solution Approach 1:
The holder is designed to vibrate during vehicle operation through relative movement with respect to the vehicle structure. This vibration automatically dislodges particles from the filter medium without requiring external cleaning equipment, thereby extending filter service life while preserving filter medium integrity.
Solution Approach 2:
The filter device performs self-cleaning through the vibration of the holder during normal vehicle operation. The relative movement between the holder and vehicle structure generates sufficient vibration to remove particles autonomously, eliminating the need for manual cleaning or replacement interventions.
2Reliability
If the filter is replaced frequently to maintain performance, then clean air filtration is ensured, but maintenance time and vehicle downtime increase
Solution Approach 1:
The self-cleaning mechanism operates continuously during vehicle operation through the ongoing relative movement between the holder and vehicle structure. This continuous vibration prevents particle accumulation that would degrade filtration performance, eliminating the need for periodic maintenance interruptions.
Solution Approach 2:
The filter automatically cleans itself during normal vehicle operation without requiring manual intervention. The holder's vibration during driving conditions continuously removes particles, maintaining filtration performance without scheduled maintenance downtime.
3Ease of operation
If additional cleaning equipment is added to the filter device, then cleaning effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
The holder serves dual functions: supporting the filter medium during operation and generating cleaning vibration through relative movement with the vehicle structure. This multi-functionality eliminates the need for separate cleaning mechanisms, maintaining simplicity while achieving effective particle removal.
Solution Approach 2:
The holder's relative movement with the vehicle structure during normal operation provides the cleaning action. No additional cleaning equipment is required as the existing structural dynamics are utilized for autonomous particle removal.
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
Enhances filter service life by self-cleaning the filter medium through natural vehicle movements, reducing maintenance frequency and costs while preserving the filter integrity.
Implementation Method 1
The stop primarily causes the filter medium to vibrate when the holder hits the stop. This vibration of the filter medium causes particles such as dust particles to be knocked out of the filter medium.
Implementation Method 2
If, for example, the component is set in motion from a resting state, the holder and the filter medium move with a time delay due to inertia, creating a relative movement between the holder and the component.
Implementation Method 3
The relative movement between the holder and component alone ensures that particles contained in the filter medium get out of the filter medium, in particular fall out downwards.
