Dynamic Dual Brush Head Push Broom for Edge Debris Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional push brooms have limitations such as unequal force distribution across the brush head, allowing debris to escape at the edges and requiring additional force to dislodge stuck debris, due to large gaps between bristles and uneven sweeping motion.
Innovation Solution
A double action push broom with a dynamic dual brush head that rotates using a torsion spring mechanism, providing an additional sweeping motion at the end of the stroke to collect debris and loosen stuck particles, ensuring thorough cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a push broom with a wide brush head and short bristles is used to handle heavy duty sweeping, then the broom can push larger amounts of debris, but the force distribution across the brush head becomes unequal allowing debris to escape at the edges
Solution Approach 1:
The brush head is made dynamically movable relative to the handle through a pivot joint, allowing it to rotate and tilt during the sweeping stroke. This dynamic adjustment enables the brush head to maintain optimal contact with the floor surface and adapt to varying debris loads, ensuring equal force distribution across the entire brush width and preventing debris escape at edges.
Solution Approach 2:
The brush head automatically adjusts its angle and position through the pivot joint mechanism in response to the sweeping motion and debris resistance. This self-adjusting capability allows the brush head to optimize its own force distribution without user intervention, maintaining effective debris collection across the entire brush width throughout the sweeping stroke.
2Productivity
If the brush head is made wide to cover more surface area, then more debris can be swept at once, but large gaps between bristles allow debris to slip past
Solution Approach 1:
The dynamically movable brush head rotates and tilts during the sweeping stroke, causing the bristles to flex and close gaps between them. This dynamic motion ensures that debris cannot slip through gaps, as the bristles adapt their positioning to maintain continuous contact with the floor surface across the entire brush width.
Solution Approach 2:
The pivot joint mechanism introduces a rocking or vibratory motion to the brush head during sweeping. This mechanical vibration helps bristles flex and close gaps between them, preventing debris from slipping through while maintaining wide brush coverage for high productivity.
3Ease of operation
If the handle is positioned at the center of the brush head to allow force application, then the user can push the broom, but the force distribution remains unequal requiring additional force to dislodge stuck debris
Solution Approach 1:
The pivot joint allows the brush head to dynamically adjust its angle relative to the handle during the sweeping stroke. This dynamic adjustment redistributes the force applied through the handle evenly across the entire brush width, eliminating the need for additional force to dislodge stuck debris and improving overall cleaning efficiency while maintaining ease of operation.
4Device complexity
If a traditional stationary brush head is used, then the structure is simple, but the broom requires continuous user force to maintain sweeping motion and cannot provide additional cleaning action
Solution Approach 1:
The pivot joint mechanism adds minimal structural complexity while enabling the brush head to dynamically rotate and tilt during sweeping. This dynamic capability provides additional cleaning action as the brush head automatically adjusts to debris resistance and floor irregularities, significantly improving cleaning effectiveness without substantially increasing device complexity.

AI summary
The double action cleaning tool of the present invention includes a dynamic double action dual brush head and a handle. The dynamic double action dual brush head includes two brush heads rotatably attached to a brush head base, allowing the brush heads to independently rotate about the axis in which it is rotatably attached to the brush head base. A mechanical device capable of storing and releasing energy is connected between the two brush heads, which is rigidly attached to the brush head base. The double action cleaning tool stores energy in the form of potential energy in the mechanical energy storage device of the dynamic double action dual brush head during the sweeping stroke of the double action push broom. At the end of the sweeping stroke, the stored potential energy is converted into kinetic energy and rotates the dual brush, thereby providing an additional sweeping motion.
