Snow-Clearing Vehicle Sweeper-Blower with Segmented Air Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow-clearing vehicles struggle to efficiently and safely remove snow from large surfaces at high speeds without causing damage to nearby objects, as they require high air speeds from limited blow-air openings, which increases the risk of lateral snow damage.
Innovation Solution
A snow-clearing vehicle with a sweeper-blower arrangement featuring multiple blow-air openings on both sides of the vertical axis, allowing simultaneous and identical operation to achieve even air distribution along the sweeping-roller brush, enabling improved snow removal and reduced risk of damage by allowing for adjustable and pivoting blow-air openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high air speed is used from limited blow-air openings to remove snow efficiently, then snow removal efficiency is improved, but the risk of lateral snow damage to airplanes or vehicles increases
Solution Approach 1:
The patent divides the single blow-air opening into multiple blow-air openings (at least four) arranged along the sweeping-roller brush. This segmentation distributes the air flow across multiple openings, reducing the air speed required at each opening while maintaining overall snow removal effectiveness, thereby reducing lateral snow damage risk
Solution Approach 2:
The patent positions blow-air openings at different locations along the sweeping-roller brush to create localized air streams that act on snow in specific zones. This local quality approach ensures even air distribution along the brush length, improving snow removal efficiency without requiring excessive air speed that would cause lateral damage
2Area of moving object
If the sweeping-roller brush is angled at a greater degree to increase work surface, then the work surface area is enlarged, but the snow removal efficiency decreases
Solution Approach 1:
The patent combines the sweeping function of the rotating brush with the blowing function of multiple air openings into a single sweeper-blower arrangement. This merging allows the brush to be positioned at optimal angles for maximum work surface area while the coordinated air streams from multiple openings ensure efficient snow removal regardless of the brush angle
3Device complexity
If a single blow-air opening is used to simplify the device structure, then device complexity is reduced, but snow removal efficiency on large surfaces decreases
Solution Approach 1:
The patent segments the blow-air function into multiple openings arranged along the sweeping-roller brush, enabling effective snow removal from large surfaces. The segmented structure is integrated into the existing vehicle framework, minimizing additional complexity while significantly improving productivity
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 improved blow-air distribution results in enhanced snow removal efficiency, allowing for a larger work surface and reduced risk of damage to aircraft or vehicles, as the vehicle can operate at slower speeds with greater air volume and more controlled snow deposition.
Implementation Method 1
an airstream is generated from the corresponding end of the sweeping-roller brush for removing snow
Implementation Method 2
blowing air simultaneously and in an equal or identical manner

AI summary
Snow-clearing vehicle (1), having a sweeper-blower arrangement (10), wherein the sweeper-blower arrangement is adjustably pivotable around a vertical axis (13) which runs through the snow-clearing vehicle. The sweeper-blower arrangement has a sweeping-roller brush (4) which is rotatingly drivable around its longitudinal axis. In the direction of travel, blow-air openings (5, 6, 7, 8) arranged on both sides of the vertical axis are provided in front and along the sweeping-roller brush (4), which are arranged for simultaneous and identically acting blowing. This allows for an improved removal of the snow to be cleared.
