Solution Overview
Problem
Existing cleaning robots with automatic dust collection face challenges in completely emptying the dust box due to insufficient wind power of the fan and inadequate dust-collection airflows.
Innovation Solution
The automatic cleaning apparatus features a dust box with asymmetrically disposed air inlet doors, creating a convection current that forms a vortex cyclone, enhancing dust suction efficiency and allowing for smoother dust collection into a dust-collection station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single air inlet configuration is used in the dust box, then the structure is simple, but the dust collection airflow is insufficient and dust cannot be completely emptied
Solution Approach 1:
The dust box air inlet is segmented into multiple independent air inlet doors (first air inlet door and second air inlet door) positioned at different locations and orientations. This segmentation allows each door to capture airflow from different directions, collectively providing sufficient dust collection airflow while maintaining reasonable structural complexity
Solution Approach 2:
The air inlet doors are arranged in different spatial dimensions and orientations within the dust box. The first air inlet door is positioned at one location while the second air inlet door is positioned at another location with a different orientation, creating multi-dimensional airflow intake that enhances dust collection capability
2Quantity of substance
If the fan wind power is increased to improve dust emptying, then dust collection capability is improved, but energy consumption increases
Solution Approach 1:
The invention utilizes pneumatic principles by designing air inlet doors that leverage natural airflow dynamics and pressure differentials created during robot movement. The multi-door configuration optimizes airflow distribution and pressure utilization, enabling effective dust emptying through aerodynamic design rather than relying solely on increased fan power
Solution Approach 2:
The invention changes the airflow parameters (direction, distribution, and velocity distribution) by implementing multiple air inlet doors at different positions and orientations. This parameter optimization allows the existing fan to achieve better dust emptying performance by improving airflow efficiency rather than increasing power consumption
