Radiator Screen Dust Removal via Vehicle Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiator screen devices for construction machines, agricultural machines, and industrial vehicles require additional actuators and energy to remove dust, leading to increased costs and neglected maintenance due to the complexity of the dust removal process.
Innovation Solution
A radiator screen device that utilizes the vibration of the vehicle body to move a zigzag-shaped wire dust removing member relative to the screen, eliminating the need for an additional actuator by leveraging the vehicle's natural vibrations to dislodge and remove dust from the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a brush is provided on the screen to remove dust, then dust removal capability is improved, but device complexity and cost increase due to requiring an actuator
Solution Approach 1:
The patent applies mechanical vibration by utilizing the vehicle body's natural vibrations to move the screen relative to the brush. The brush is positioned to contact the screen surface, and relative movement between the brush and screen during vehicle operation removes dust accumulation without requiring an additional actuator mechanism.
Solution Approach 2:
The system uses the vehicle body's own vibrations as the driving force for dust removal. The screen and brush are configured so that normal vehicle operation generates the necessary relative movement to clean the screen, making the system self-servicing without external energy input or control mechanisms.
2Object-generated harmful factors
If an actuator is used to move the brush for dust removal, then dust removal effectiveness is improved, but energy consumption increases
Solution Approach 1:
The system uses the vehicle body's own vibrations as the driving force for dust removal. The screen and brush are configured so that normal vehicle operation generates the necessary relative movement to clean the screen, making the system self-servicing without external energy input or control mechanisms.
Solution Approach 2:
The patent applies mechanical vibration by utilizing the vehicle body's natural vibrations to move the screen relative to the brush. The brush is positioned to contact the screen surface, and relative movement between the brush and screen during vehicle operation removes dust accumulation without requiring an additional actuator mechanism.
3Object-generated harmful factors
If screen maintenance is performed manually, then dust removal is effective, but maintenance time and operational downtime increase
Solution Approach 1:
The dust removal action occurs continuously during vehicle operation rather than requiring periodic manual intervention. The brush maintains contact with the screen throughout operation, and the vehicle's vibrations continuously generate relative movement that prevents and removes dust accumulation in real-time.
Solution Approach 2:
The system uses the vehicle body's own vibrations as the driving force for dust removal. The screen and brush are configured so that normal vehicle operation generates the necessary relative movement to clean the screen, making the system self-servicing without external energy input or control mechanisms.
Applied Scientific Principles

Function Achieved in This Case
Effectively removes dust from the radiator screen without additional energy consumption, reducing air flow resistance and simplifying maintenance by utilizing the vehicle's vibrations to clean the screen, thereby enhancing operational efficiency and reducing costs.
Implementation Method 1
One of the dust removing member and the screen is vibrated relative to the other of the dust removing member and the screen by vibration of the vehicle body

AI summary
A radiator screen device for a construction machine, an agricultural machine, or an industrial vehicle, each having a vehicle body and a radiator, includes a screen to filter dust contained in cooling air flowing toward the radiator, and a dust removing member disposed upstream of the radiator with respect to a flowing direction of cooling air and movable relative to the screen in contact with a surface of the screen to remove dust attached to the screen. The dust removing member and the screen are supported by the vehicle body. One of the dust removing member and the screen is vibrated relative to the other of the dust removing member and the screen by vibration of the vehicle body.
