Multi-Row Sweeping Blade Offset Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snowplowing vehicles face issues with uneven surfaces and obstacles causing premature damage to sweeping blades and inefficient snow removal due to limited angular movement and creation of interstices that allow snow to pass through.
Innovation Solution
A sweeping blade assembly with two rows of blades, where each row is positioned to overlap gaps in the other row, allowing for free vertical and angular movement, and featuring reversible carbide-coated blades attached via compressible bushings for enhanced durability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If blades are arranged in a single row with fixed spacing, then the structure is simple, but the blades cannot move freely on uneven surfaces causing premature damage and inefficient snow removal
Solution Approach 1:
The blade assembly is divided into multiple independent rows (first row and second row) with blades spaced apart within each row. This segmentation allows each blade to move independently vertically and angularly when contacting uneven surfaces, resolving the contradiction between movement freedom and structural simplicity.
Solution Approach 2:
The patent transitions from a single-row blade arrangement to a multi-row arrangement where blades are positioned in both horizontal and vertical dimensions. The first row and second row are offset from each other, creating a three-dimensional configuration that enables greater angular movement freedom while maintaining structural organization.
2Area of stationary object
If blades are positioned close together, then the coverage area is maximized, but interstices are created that allow snow to pass through
Solution Approach 1:
By arranging blades in multiple rows offset from each other in the vertical dimension, the patent eliminates horizontal interstices that would allow snow to pass through. The offset positioning ensures that when one row has gaps, the other row provides coverage, maintaining continuous snow removal without traces.
Solution Approach 2:
The multi-row offset arrangement ensures continuous coverage across the entire width of the blade assembly. As blades in one row move or create gaps, the offset positioning of the other row maintains uninterrupted snow removal action, preventing snow from passing through to create traces.
3Reliability
If blades have limited angular movement, then the structure remains stable, but protruding obstacles cause uneven wear and damage
Solution Approach 1:
The blade assembly is segmented into multiple independent rows with blades spaced apart, allowing each blade to move angularly independently when encountering protruding obstacles. This segmentation prevents the transmission of impact forces across the entire assembly, reducing uneven wear and improving blade durability.
Solution Approach 2:
The patent introduces dynamic movement capability to the blade assembly, allowing blades to move vertically and angularly in response to uneven surfaces and protruding obstacles. This dynamic adaptation reduces impact forces and wear on individual blades, improving overall reliability and durability.

AI summary
A sweeping blade assembly for attachment to a vehicle for sweeping a ground surface. The sweeping blade assembly comprises: a blade support for receiving a plurality of blades, a first row of blades and a second row of blades. Each row of blade comprising a plurality of blades which are separated from each other by a gap. The first row of blades and the second row of blades are provided beside (and parallel to) each other and positioned so that a given gap in a given row corresponds to a blade in the other row. In an embodiment, the gap is dimensioned to be smaller in width than the blades whereby a given blade in one row can have a partial overlap of two different blades in the other row. Whereby, the blades can freely move vertically and/or angularly when hitting uneven surfaces, and can be rectangular in shape, and thus reversible when the carbide on one of the edges is worn out.
