Single-Piece Molded Broom with Integrated Fine Dust Sweeping Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brooms are inadequate in efficiently handling both coarse and fine particles, as they often require separate tools or complex maneuvers to manage different sizes of debris effectively.
Innovation Solution
A single-piece molded broom with an elongated base member, an array of spaced bristles, and a fine dust sweeping element protruding from the bottom face, allowing for simultaneous engagement with a surface using the bristles and optional fine dust edge, made from silicone or silicone rubber for enhanced flexibility and effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional broom with only bristles is used, then coarse particles can be swept effectively, but fine particles cannot be swept efficiently
Solution Approach 1:
The broom head is segmented into two distinct functional zones: a bristle array for coarse particle removal and a fine dust sweeping element for fine particle collection. This segmentation allows each zone to specialize in handling specific particle sizes, thereby resolving the contradiction between sweeping efficiency and adaptability to different particle types.
Solution Approach 2:
The broom head is designed as a multi-functional tool that can simultaneously handle both coarse and fine particles. The bristle array addresses coarse debris while the fine dust sweeping element captures fine particles, making the single broom universal for various sweeping needs without requiring separate tools.
2Adaptability or versatility
If separate tools are used for coarse and fine particles, then each particle type can be handled effectively, but device complexity increases
Solution Approach 1:
The invention merges the functions of separate brooms into a single integrated broom head. The bristle array and fine dust sweeping element are combined in one structure, allowing users to handle both coarse and fine particles with a single tool, thereby reducing device complexity while maintaining versatility.
Solution Approach 2:
By designing the broom head as a universal tool with dual functionality, the invention eliminates the need for multiple specialized tools. The single broom head performs both coarse particle sweeping and fine particle collection, simplifying the user's toolset while maintaining adaptability.
3Productivity
If the fine dust sweeping element protrudes below the bristle plane, then fine particles can be swept effectively, but the sweeping edge may interfere with bristle engagement
Solution Approach 1:
The fine dust sweeping element is designed with local quality differentiation: it protrudes below the bristle plane only at the lateral edges where fine particle collection is needed, while the central bristle array remains uninterrupted for effective coarse particle engagement. This localized configuration allows fine particle sweeping without interfering with bristle function.
Solution Approach 2:
The fine dust sweeping element extends in a different spatial dimension - laterally at the edges rather than centrally among the bristles. This dimensional arrangement allows the sweeping edge to contact the surface for fine particle collection without interfering with the vertical bristle engagement, providing ease of operation for both functions.

AI summary
The present disclosure provides a broom, specifically a broom head that is made of a single mold and therefore is a single-piece molded article. The broom includes a base member having two opposite faces, a bottom face and a top face. The base member is elongated along a longitudinal direction between first and second ends. An array of bristles intended to perform the sweeping activity protrudes from the bottom face and a rod receptacle configured to receive a rod for handling the broom protrudes from the top face. Each of the bristles of the array is spaced apart from any other bristle. To facilitate utilizing the broom also to sweep small particles, the broom further includes a fine dust sweeping element that protrudes from the bottom face, typically from an edge of the base member extending between the first and second ends.
