Double Broom with Roller-Based Self-Lifting for Wide-Area Sweeping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brooms require manual lifting during the return movement, which is energetically inefficient and limits the working width, and they often struggle with uneven surfaces.
Innovation Solution
A double broom system with a self-lifting function, utilizing rollers and elastic fittings as a torsion joint, allowing the broom body to lift during the backward sweeping movement and roll back over debris, eliminating the need for manual lifting and enabling adjustable broom widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual lifting is used during return movement, then the broom can be reset, but energy consumption increases and handling becomes more difficult
Solution Approach 1:
The broom body automatically lifts itself during the backward movement through the interaction of rollers and elastic suspension, eliminating the need for manual lifting effort and reducing energy consumption
Solution Approach 2:
The elastic suspension system with springs acts as a counterweight mechanism, storing energy during forward movement and releasing it during backward movement to automatically lift the broom body, compensating for the weight that would otherwise require manual lifting
2Productivity
If broom width is increased to cover larger areas, then productivity improves, but handling and maneuverability become more difficult
Solution Approach 1:
The broom is divided into two separate broom bodies connected by elastic fittings, allowing each broom to be independently maneuvered while maintaining a wide working width, thus improving both productivity and ease of operation
Solution Approach 2:
The elastic fittings allow the broom configuration to dynamically adapt to different working conditions and space constraints, enabling the broom to transition between wide and narrow configurations for optimal maneuverability while maintaining large sweeping coverage
3Productivity
If conventional single broom design is used, then structure is simple, but working width is limited and productivity is reduced
Solution Approach 1:
The broom system is segmented into two independent broom bodies that can be connected or separated, allowing the working width to be doubled when connected while maintaining the simplicity of individual broom structures
Solution Approach 2:
The elastic fittings serve multiple functions: connecting the two brooms to increase working width, allowing independent movement for maneuverability, and providing suspension for automatic lifting, thus achieving increased productivity without proportionally increasing structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The double broom system reduces handling effort, increases the working width, and maintains a gentle posture for efficient sweeping, covering larger areas with less energy expenditure.
Implementation Method 1
Roller suspension with relaxed spring in the backward movement (7)
Implementation Method 2
The fittings (e.g., optionally fabric hoses) (Fig. 4, Photo 4) function as a torsion joint and compensate for unevenness in the floor
Implementation Method 3
the double broom does not have to be lifted during the return movement. It rolls back over the debris

AI summary
The double broom with self-lifting function is an invention that facilitates or even enables working with brooms of a large span. The invention is based on a roller system integrated into the broom that lifts the broom body during the return stroke. The purpose of the invention is to clean large areas in a much more ergonomic posture compared to conventional brooms. To ensure cleaning uneven surfaces, the tool is equipped with a joint in the middle that compensates for irregularities in the horizontal plane.
