Solution Overview
Problem
Current cleaning robots experience low debris discharging efficiency, resulting in residual debris remaining in the debris bin after reverse vacuuming.
Innovation Solution
The debris bin assembly includes a debris bin housing with an inner cavity, air inlet, debris outlet, and air guide portions, where the air inlet is in communication with the cleaning robot's debris inlet channel, and a debris discharge valve that opens in response to vacuum negative pressure to evacuate debris, and a movable valve that covers the air guide port after suction is withdrawn, enhancing airflow and debris evacuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If reverse vacuuming is used to evacuate debris from the robot's debris bin, then debris can be discharged from the bin, but a large amount of debris remains in the bin and discharging efficiency is low
Solution Approach 1:
The debris bin housing is divided into multiple air guide portions, each directing airflow to different regions of the bin. This segmentation allows comprehensive coverage of debris throughout the bin cavity, ensuring thorough evacuation without leaving residual debris in any particular area.
Solution Approach 2:
Airflow is introduced from multiple directions through the air guide portions rather than a single direction. This multi-dimensional airflow approach ensures that debris throughout the entire bin volume is effectively evacuated, significantly improving discharge efficiency and reducing residual debris.
2Ease of manufacture
If the debris bin is designed with simple structure for ease of manufacture, then manufacturing is easier, but airflow control and debris evacuation efficiency are insufficient
Solution Approach 1:
The air guide portions are strategically positioned at specific locations within the debris bin housing to optimize airflow distribution. Each air guide portion is located to target specific regions where debris accumulates, providing localized airflow enhancement without requiring complete redesign of the entire bin structure.
Solution Approach 2:
The air guide portions serve multiple functions: they guide airflow into the bin cavity, direct air toward debris accumulation areas, and work cooperatively with the vacuum cleaner's suction. This multi-functionality achieves improved evacuation efficiency without proportionally increasing structural complexity.
