Retractable Broom Housing for Adjustable Bristle Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brooms are inconvenient to carry and store due to exposed bristles and limited functionality, with previous solutions only addressing the storage issue partially while maintaining a single function.
Innovation Solution
A multifunctional broom with a contractible positioning mechanism that allows the broom head housing to adjust along the broom pole, enabling the broom to function as a scraper, brush, and cleaner by controlling the length of the bristle exposure, and includes a bucket for easy dirt collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bristles are always exposed outside the broom head, then the broom can function for cleaning, but it is very inconvenient to carry and store the brooms
Solution Approach 1:
The broom head housing is designed to be axially movable along the broom pole, allowing the bristle exposure length to be dynamically adjusted. The contractible positioning mechanism enables the housing to move between extended (bristles exposed for cleaning) and retracted (bristles hidden for compact storage) positions, resolving the contradiction between ease of carrying and functional availability
2Adaptability or versatility
If the broom is designed with single function, then the structure is simple, but it cannot meet diverse cleaning needs
Solution Approach 1:
The broom is designed with multi-functionality by enabling the same broom head to serve different purposes through adjustable bristle exposure. By controlling the extension length of the broom head housing, the broom can function as a full-brush cleaner, a partial-brush cleaner, or a scraper (when bristles are fully retracted), allowing one structure to meet diverse cleaning needs without increasing complexity
Solution Approach 2:
The dynamic adjustment of broom head housing position along the pole enables the broom to transform between different functional states. The contractible positioning mechanism allows smooth transition between functions (scraper, brush, cleaner) by adjusting bristle exposure, achieving multi-functionality without complex structural additions
3Adaptability or versatility
If the bristle exposure length is fixed, then the structure is simple, but it cannot adapt to different cleaning requirements
Solution Approach 1:
The broom head housing is designed with axial movability along the broom pole, enabling dynamic adjustment of bristle exposure length. The contractible positioning mechanism provides discrete positioning points along the pole, allowing the housing to be adjusted to different heights for varying bristle exposure, thus adapting to different cleaning requirements without excessive complexity
Solution Approach 2:
The positioning mechanism is segmented into discrete gear positioning holes distributed along the broom pole. The switching mechanism engages with these holes to provide stable positioning at different heights, allowing stepwise adjustment of bristle exposure length. This segmented approach simplifies the positioning control while maintaining adaptability

AI summary
The present utility model belongs to the technical field of cleaning tools and particularly relates to a multifunctional broom in order to solve the problems such as a single function of existing brooms. The multifunctional broom comprises a broom pole and a broom head disposed at one end of the broom pole, wherein a broom head housing axially movably disposed on the broom pole is provided in the periphery of the broom head, an opening for allowing the lower end of the broom head to extend from the broom head housing is formed at the lower end of the broom head housing, and a contractible positioning mechanism for enabling the broom head housing to be positioned on the broom pole, when the length of the lower end of the broom head extending from the broom head housing is adjusted to a desired length, is provided between the broom pole and the broom head housing. The multifunctional broom is multiple-purpose and functions as a scraper, a brush and a broom by controlling the length of the broom head extending from the broom head housing by a contractible positioning mechanism; moreover, the dirt on the bristles is easy to clean, so the multifunctional broom is convenient to use and easy to carry and store.
