Angled Bristle Holder for Corner Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning brushes, including snow brushes and feather dusters, struggle to effectively clean corners and edges without deforming bristles or requiring excessive force, which can lead to reduced cleaning effectiveness and potential damage.
Innovation Solution
A dust brush design featuring a bristle holder with angled partial surfaces and adjustable bristle lengths, allowing the brush to be positioned to penetrate corners without bending, and a coupling device for reaching hard-to-clean areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cleaning brushes with round or flattened contours are used, then they can clean general surfaces, but they cannot effectively clean corners or edges without deforming bristles or requiring excessive force
Solution Approach 1:
The bristle holder is divided into multiple legs (first leg, second leg, third leg) with bristles attached at different angles and positions. This segmentation allows different parts of the brush to access different areas (corners, edges, flat surfaces) simultaneously, enabling corner cleaning without bristle deformation
Solution Approach 2:
The bristle holder features asymmetric geometry with legs of different lengths and orientations. The first leg has bristles at a first angle, the second leg at a second angle, and the third leg at a third angle, creating an asymmetric configuration that specifically targets corner and edge geometries while maintaining bristle integrity
2Productivity
If force is exerted on feather dusters to penetrate wall corners, then dirt can be removed, but bristles buckle and cleaning effectiveness is reduced
Solution Approach 1:
The bristles are pre-positioned at multiple angles and lengths during manufacturing, so that when the brush is inserted into a corner, the bristles are already oriented to penetrate the corner geometry without requiring force-induced buckling. The asymmetric leg configuration pre-establishes the optimal bristle orientation for corner access
Solution Approach 2:
The brush design incorporates dynamic adaptability where bristles of different lengths and angles naturally adjust to the corner geometry upon insertion. The varying bristle lengths allow shorter bristles to contact wall surfaces while longer bristles penetrate into the corner area, creating a dynamic cleaning action without buckling
3Manufacturing precision
If cleaning brushes are designed for specific corner angles, then they can clean those specific corners, but they cannot adapt to different wall surface angles
Solution Approach 1:
The bristle holder is designed with multiple legs having bristles at different angles (first angle, second angle, third angle) and different lengths. This multi-functional configuration allows the single brush to effectively clean various corner angles (90°, 135°, and other angles) by selecting the appropriate leg-bristle combination for each specific corner geometry
Solution Approach 2:
The invention varies multiple parameters simultaneously - bristle angle, bristle length, and leg orientation - to create an adaptable system. By having bristles at different angles and lengths on different legs, the brush can adjust its effective cleaning parameters to match different wall surface angles and corner geometries

AI summary
The invention relates to a cleaning brush (1) having a bristle holder (2) and bristles (11) that are fastened to the bristle holder (2) and form a brush surface. The bristle holder (2) preferably has two limbs (10, 20). Known cleaning brushes have the disadvantage that they cannot reach all corners. The invention improves upon said problem in that the bristles (11, 21) fastened to the bristle holder (2) form a first, second and third sub-surface (T1, T2, T3) that together form the brush surface. The individual sub-surfaces (T1, T2, T3) are arranged such that they are each angled to one another, and preferably that a value of a first angle a formed between the first and third sub-surfaces (T1, T3) differs from a value of a second angle ß formed between the second and third sub-surfaces (T2, T3).
