Dynamic Dual Brush Head Torsion Spring Sweeping Mechanism
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.
Innovation Solution
A double action cleaning tool with a dynamic double action dual brush head that automatically provides an additional sweeping motion at the end of a sweep stroke, using a torsion spring mechanism to rotate the brush heads and ensure debris is collected effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a push broom uses a large brush head with short bristles to cover more surface area, then productivity is improved, but force distribution becomes unequal allowing debris to escape at edges
Solution Approach 1:
The brush head is made dynamically movable relative to the handle through a pivot joint, allowing the brush head to rotate and adjust its angle automatically during the sweeping stroke. This dynamic adjustment ensures that the brush head maintains optimal contact with the floor surface throughout the sweeping motion, improving debris collection effectiveness while maintaining large surface area coverage.
Solution Approach 2:
The cleaning tool is divided into separable components including a removable brush head attachment and a handle. This segmentation allows the brush head to be independently optimized for surface coverage while the handle provides leverage, and enables the brush head to be detached for cleaning or replacement without affecting the handle structure.
2Productivity
If a push broom uses a large brush head with spaced bristles to cover more area, then productivity is improved, but gaps between bristles allow debris to slip past
Solution Approach 1:
The dynamically movable brush head rotates during the sweeping stroke to angle the bristles optimally toward the center collection point. This dynamic bristle angling ensures that debris is directed inward rather than slipping through gaps, improving capture completeness while maintaining high sweeping speed through the large brush head area.
3Ease of operation
If a push broom uses a center-mounted handle to provide leverage, then ease of operation is improved, but force distribution becomes unequal causing debris to lodge in bristles
Solution Approach 1:
The pivot joint enabling dynamic brush head movement also facilitates automatic debris discharge. As the brush head rotates during and after the sweeping stroke, debris lodged in the bristles is naturally dislodged and directed toward the center collection point, improving debris discharge efficiency while maintaining the center-mounted handle for ease of operation.
4Reliability
If a push broom requires additional force to dislodge stuck debris, then cleaning thoroughness is improved, but ease of operation deteriorates
Solution Approach 1:
The dynamic brush head design uses the sweeping motion itself to automatically dislodge and discharge debris through rotational movement. This eliminates the need for additional user force or manual intervention to remove stuck debris, maintaining cleaning thoroughness while significantly improving ease of operation by reducing user effort.
Solution Approach 2:
The brush head automatically discharges debris through its dynamic rotational movement during the sweeping stroke. The system serves itself by using the sweeping motion to both collect and discharge debris without requiring separate user actions, improving ease of operation while maintaining cleaning thoroughness.

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.
