Dual Dust Unit Sweeper Airflow for Mixed Refuse Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning apparatuses, such as floor sweepers, face challenges in effectively handling a wide range of refuse types across different usage areas, leading to suboptimal cleaning performance.
Innovation Solution
The design incorporates a main body with rotating wheels, a main brush, and detachable dust units with optimized passageways and jet ports, allowing for improved dust collection and refuse management by selecting the appropriate dust unit based on refuse type, and utilizing a dust-collecting assembly with a fan and motor to enhance cleaning characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single dust unit is used in the cleaning apparatus, then the device complexity is reduced, but the adaptability to handle various refuse types deteriorates
Solution Approach 1:
The dust collecting assembly is segmented into multiple detachable dust units (first dust unit and second dust unit), each with different passageway configurations. This allows the cleaning apparatus to handle various refuse types by selecting the appropriate dust unit, while maintaining relatively simple individual unit designs that can be independently attached or removed.
2Adaptability or versatility
If the passageway is optimized for one type of refuse, then the manufacturing precision is improved, but the adaptability to different refuse types deteriorates
Solution Approach 1:
The passageway configuration is made dynamic through the ability to detach and replace dust units. Each dust unit has a passageway optimized for specific refuse types, and the system adapts to different cleaning needs by dynamically switching between units rather than requiring a single complex passageway design to handle all scenarios.
3Ease of operation
If a detachable dust unit system is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The detachable dust units are designed with universal mounting interfaces that can be attached to and detached from the main body in a standardized manner. This universal design simplifies operation by providing consistent attachment mechanisms across different unit types, while the modular architecture manages complexity by allowing units to be independently designed and replaced without affecting the overall system structure.

Function Achieved in This Case
This configuration enhances the cleaning apparatus's ability to handle various refuse types, improving cleaning efficiency by optimizing dust collection and reducing refuse agitation and accumulation issues.
Implementation Method 1
a dust-collecting fan; a dust-collecting motor, which rotates the dust-collecting fan; and an outflow port, from which gas that has passed through the dust-collecting fan flows out

AI summary
A cleaning apparatus includes: a main body; wheels movably supporting the main body; a main brush rotatably supported in (by) the main body and configured to brush up refuse on a surface-to-be-cleaned; a first dust unit, which is detachable from the main body and into which refuse brushed up by the main brush is dispatched; a second dust unit, which is detachable from the main body and into which refuse brushed up by the main brush is dispatched; and a dust-collecting assembly comprising: a dust-collecting fan; a dust-collecting motor, which rotates the dust-collecting fan; and an outflow port, from which gas that has passed through the dust-collecting fan flows out; the dust-collecting assembly being configured to suction dust swept up by the main brush. The first dust unit and the second dust unity respectively have a first passageway and a second passageway, into which gas from the outflow port flows.
