Vehicle Broom With Offset Brush Series And Deflectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brooms for self-propelled vehicles struggle to effectively sweep and collect debris, especially against vertical obstacles and large surfaces, due to limited collection capacity and obstruction by the broom body, leading to incomplete cleaning and saturation issues.
Innovation Solution
A broom design with multiple series of brush bristles and deflectors that create extended collection zones, allowing for efficient sweeping and recovery of debris by offsetting bristle rows and using deflectors to redirect escaped or accumulated material towards collection areas, increasing storage capacity and recovery capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single series of brush bristles is used, then the structure is simple, but the collection capacity is limited and saturation occurs quickly
Solution Approach 1:
The broom is divided into multiple series of brush bristles (first series, second series, and optionally third series) arranged in sequence from front to back. Each series has its own collection zone, segmenting the overall collection function into multiple stages. This segmentation increases total collection capacity while maintaining manageable structural complexity through modular arrangement.
Solution Approach 2:
The invention extends the collection function from a single plane to multiple depth zones by arranging brush series sequentially along the longitudinal axis. The first series collects debris in the front collection zone, the second series collects in the rear collection zone, and optionally the third series provides additional rear collection. This dimensional extension along the length dimension dramatically increases collection capacity.
2Productivity
If the broom body is positioned close to the surface, then it effectively cleans the surface, but it obstructs access to debris against vertical obstacles like walls
Solution Approach 1:
The deflectors are extracted as separate functional elements from the main broom body structure. These deflectors can be positioned independently to guide debris away from vertical obstacles and into the collection zones, allowing the broom body to maintain its cleaning effectiveness on flat surfaces while the deflectors handle the adaptation to vertical obstacles.
Solution Approach 2:
The deflectors act as intermediary elements between the broom body and debris against vertical obstacles. They mediate the interaction by redirecting debris flow from the obstacles into the collection zones, enabling the broom to effectively clean both flat surfaces and areas adjacent to vertical structures without the body itself needing to contact the obstacles.
3Device complexity
If a single collection zone is used, then the structure is simple, but debris is rejected at the edges when the surface is large
Solution Approach 1:
The collection function is segmented into multiple collection zones: a front collection zone associated with the first series of brush bristles and a rear collection zone associated with the second series. Each zone has its own deflectors and brush configuration, segmenting the debris collection process into multiple stages that prevent edge rejection and improve overall recovery capability.
Solution Approach 2:
The multiple series of brush bristles and associated collection zones create a continuous debris collection action along the longitudinal axis. As debris is collected in the front zone, it is continuously processed and transferred to the rear zone, maintaining continuous useful action throughout the broom's length rather than having a single saturation point.

AI summary
The invention relates to a broom for a self-propelled vehicle comprising an elongated body (1) which is equipped with means for adapting to the vehicle and which comprises, at the level of an underside face, a first series (S1) of longitudinal rows (101) of brush bristles extending in a direction substantially normal to the underside face, the rows (101) of said first series (S1) each having, viewed from the underside face of said body, a straight shape or a curved or C-shaped or V-shaped shape, characterized by the fact that: - said elongated body (1) further comprises, at the level of the underside face, at least a second series (S2) of longitudinal rows (102) of brush bristles extending in a direction substantially normal to said underside face, said second series (S2) being arranged behind said first series (S1) and offset from the latter so as to define a sweepings collection zone,- said second series (S2) is associated with deflectors (120) oriented towards the front of the body (1) so as to direct the sweepings from the first series (S1), or which escape the passage zone of said first series (S1), towards the collection zone, - viewed from the underside of the body (1), said deflectors (120) extend beyond the lateral edges (11) of said body.
