Chevron Brush Bristle Segmentation for Dust Line Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing static brooms for self-propelled vehicles are inefficient in sweeping large surfaces, leading to the rapid appearance of finer sweepings and lines of dust or waste accumulation along the edges of the broom's passage area.
Innovation Solution
A broom design featuring two series of longitudinal brush bristles, with the first series being straight and the second series having a curved or V-shape, oriented opposite to the first series, and optionally including auxiliary rows, to enhance sweeping quality and reduce dust accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a broom comprises only straight rows of brush bristles, then the design is simple and easy to manufacture, but the sweeping quality is poor with rapid appearance of finer sweepings and dust accumulation lines
Solution Approach 1:
The broom is divided into two distinct series of brush bristle rows: a first series with straight rows and a second series with curved or V-shaped rows. This segmentation allows each series to perform different sweeping functions - the straight rows handle general sweeping while the curved rows prevent dust accumulation and capture finer sweepings, thereby improving overall sweeping quality without complicating the manufacturing process excessively.
Solution Approach 2:
The invention introduces a dimensional variation in the arrangement of brush bristle rows by adding curved or V-shaped rows complementary to the straight rows. This dimensional change in row configuration enables the broom to address multiple sweeping challenges simultaneously - the curved rows create a scanning motion that prevents dust accumulation lines while the straight rows maintain structural simplicity for easy manufacture.
2Productivity
If a broom uses curved or V-shaped rows of brush bristles, then the sweeping quality improves with reduced dust accumulation, but the device complexity increases
Solution Approach 1:
The brush bristle rows are segmented into two clear series: straight rows and curved or V-shaped rows. This segmentation organizes the complexity by assigning specific functions to each series - the curved rows handle dust accumulation prevention while the straight rows provide structural simplicity - making the overall design more manageable despite the added complexity of curved rows.
Solution Approach 2:
Different regions of the broom have different row configurations tailored to local requirements. The curved or V-shaped rows are positioned to address specific dust accumulation problems in certain areas, while straight rows are used in other areas where simplicity is prioritized. This local differentiation optimizes sweeping quality without uniformly increasing device complexity across the entire broom structure.

AI summary
The brush has an elongated body (1) comprising a series (S1) of rectilinear longitudinal rows (10-1) of brush bristles at its lower surface, where the bristles extend in a direction normal to the lower surface. The rows are parallel to a longitudinal axis of the elongated body. Another series (S2) of rectilinear longitudinal rows (10-2) of brush bristles extends in a direction normal to the lower face. The rows of the latter series are parallel to each other, where each of the rows has a curved or V shape when viewed from a lower surface of the body.
