Multifunctional broom with a rotatable head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brooms are inadequate for thorough cleaning, particularly on outdoor grounds and lawns, as they wear out quickly and cannot handle heavy wastes, and require replacement of the entire broom head when bristles become worn.
Innovation Solution
A multifunctional broom with a rotatable head featuring a rake tooth and brush head connected via telescopic mechanisms, allowing for automatic extension and retraction, enabling efficient cleaning of various surfaces and allowing for separate replacement of worn brush heads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If bristles are provided only at the head of the broom, then the structure is simple, but the cleaning thoroughness is insufficient
Solution Approach 1:
The broom head is segmented into multiple functional components: a brush head with bristles for general cleaning, a rake tooth with rake hook for outdoor grounds and lawns, and a scraping plate for heavy wastes. Each component can be independently positioned and replaced, resolving the contradiction between structural simplicity and cleaning thoroughness.
2Adaptability or versatility
If the broom head is used for rough regions such as outdoor grounds and lawns, then it can handle rough surfaces, but the broom head is prone to wear-out
Solution Approach 1:
The rake tooth is designed to be telescopic, extending out of or retracting into the broom head via a first telescopic mechanism. This dynamic adjustment allows the broom to adapt to different surface conditions - extending for outdoor grounds and lawns, retracting for indoor floors - thereby reducing unnecessary wear and extending service life.
Solution Approach 2:
The broom head components are designed as separable modules. When the brush head wears out, only the brush head needs to be replaced rather than the entire broom head, reducing maintenance costs and extending the overall service life of the broom system.
3Reliability
If the broom is used for heavy wastes such as rubble, then it can remove heavy wastes, but the existing structure provides undesirable outdoor cleaning
Solution Approach 1:
The broom head incorporates three specialized components: a scraping plate for heavy wastes like rubble, a rake tooth with rake hook for outdoor grounds and lawns, and a brush head for general cleaning. This segmentation allows each component to be optimized for its specific function while maintaining overall versatility.
Solution Approach 2:
The broom head is designed as a multi-functional unit that can handle indoor floors, outdoor grounds, lawns, and heavy wastes through its various components. The telescopic rake tooth and replaceable brush head enable the same broom structure to perform diverse cleaning tasks across different environments.
4Reliability
If the entire broom head needs to be replaced when bristles wear out, then the cleaning function is restored, but the maintenance cost increases
Solution Approach 1:
The broom head is designed with separable components including the brush head, rake tooth, and scraping plate. When the brush head wears out, only the brush head itself needs to be replaced rather than the entire broom head assembly, significantly reducing maintenance costs while restoring the cleaning function.

AI summary
The present invention relates to a broom, and in particular to a multifunctional broom with a rotatable head. According to the present invention, an brush head and a rake tooth are provided on a broom head. The rake tooth can be used for cleaning of regions such as outdoor grounds and lawns, and the brush head can be used for indoor cleaning. Moreover, the rake tooth can be extended out of or retracted into the broom head through the first telescopic mechanism. The broom of the present invention is very simple and convenient to use and provides more thorough cleaning. The first telescopic mechanism enables automatic telescoping depending on various conditions of ground, thereby providing more thorough cleaning and being more convenient and efficient (FIG. 1).
