Oblique Brush Mechanism for Road Surface Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional removal devices for guide rail type vehicles struggle to effectively remove compacted snow and firmly adhered foreign matter from road surfaces, leading to increased complexity and cost due to the need for additional operating mechanisms.
Innovation Solution
A brush section is integrated into the vehicle body, extending obliquely downward to contact the road surface, utilizing frictional forces and restoring action to flick off objects, with adjustable inclination and support mechanisms to enhance removal efficiency without additional operating mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional removal device is used, then the structure remains simple, but the device cannot sufficiently remove compacted snow or firmly adhered foreign matter from the road surface
Solution Approach 1:
The brush section is designed to be movable relative to the road surface, capable of extending and retracting. The lower end of the brush section contacts the road surface and is dragged backward by friction, then returns forward by elastic restoration, creating a flicking motion that effectively removes compacted snow and adhered foreign matter without requiring complex operating mechanisms
Solution Approach 2:
The inclination angle of the brush section is optimized at 45 degrees or less relative to the road surface. This parameter change enables the brush to effectively flick off objects while maintaining a simple structural configuration, resolving the contradiction between removal effectiveness and structural simplicity
2Reliability
If an operating mechanism for wiping off compacted snow and foreign matter is separately provided, then the removal effectiveness improves, but the structure becomes complicated which causes an increase in cost
Solution Approach 1:
The brush section utilizes the vehicle's own motion and the friction between the brush and road surface to generate the removal action. The lower end of the brush is naturally dragged backward by road surface friction during vehicle travel, then returns forward by elastic restoration, creating a self-sustaining flicking motion that eliminates the need for separate operating mechanisms
Solution Approach 2:
The invention replaces complex mechanical operating mechanisms with a simple elastic restoration system. The brush section's lower end is pulled backward by friction and returns forward by elastic force, substituting for complex wiping or scraping mechanisms while maintaining high removal effectiveness
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 allows for effective removal of objects from the road surface with a simple structure, adjusting to various states of objects and suppressing brush section rattling during non-use, thereby improving operational efficiency and reducing complexity and cost.
Implementation Method 1
the lower end is pulled to the road surface by the frictional force received from the irregularities of the road surface
Implementation Method 2
the lower end of the brush section returns to the front again by the restoring force of the brush section itself and acts to flick the road surface

AI summary
A device for removing an object on a road surface includes a brush section which is provided at a vehicle body of a guide rail type vehicle traveling on the road surface extends obliquely downward toward the front side in an advancing direction of the vehicle body, and a lower end of the brush section being capable of coming into contact with the road surface; a brush support section that fixes the brush section; a fixing section fixed to the vehicle body; and a connecting section that is interposed between the brush support section and the fixing section to connect the brush support section to the fixing section.
