Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot cleaners with cylindrical shapes excel in traveling performance but poorly clean areas like corners due to their design, while those with polygonal shapes improve corner cleaning but compromise on traveling efficiency.
Innovation Solution
A robot cleaner with a cylindrical main body and a suction device featuring a first suction member at the bottom and a second suction member that can move relative to the first, connected via a flexible pipe, allowing for variable positioning and increased cleaning area coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot cleaner has a cylindrical shape, then traveling performance is improved, but corner cleaning capability deteriorates
Solution Approach 1:
The suction device is divided into multiple independent suction members (first suction member at the bottom and second suction member at the side), each capable of independently suctioning foreign substances from different directions. This segmentation allows the cylindrical robot to effectively clean both open areas and corner regions without changing its overall cylindrical shape, thus maintaining good traveling performance while improving corner cleaning capability.
2Productivity
If the robot cleaner has a polygonal shape, then corner cleaning capability is improved, but traveling performance deteriorates
Solution Approach 1:
Instead of changing the two-dimensional shape of the robot body from cylindrical to polygonal, the invention adds a third dimension by extending a second suction member from the side surface of the cylindrical body. This allows the robot to reach into corner areas without altering its optimal cylindrical traveling shape, thus improving corner cleaning while maintaining traveling performance.
3Device complexity
If a single suction port is provided at the bottom, then the structure is simple, but cleaning area coverage deteriorates
Solution Approach 1:
The suction device is divided into multiple independent suction members (first suction member at the bottom and second suction member at the side), each capable of independently suctioning foreign substances from different directions. This segmentation allows the cylindrical robot to effectively clean both open areas and corner regions without changing its overall cylindrical shape, thus maintaining good traveling performance while improving corner cleaning capability.
Solution Approach 2:
Instead of changing the two-dimensional shape of the robot body from cylindrical to polygonal, the invention adds a third dimension by extending a second suction member from the side surface of the cylindrical body. This allows the robot to reach into corner areas without altering its optimal cylindrical traveling shape, thus improving corner cleaning while maintaining traveling performance.
4Area of stationary object
If multiple suction members are added, then cleaning area coverage is improved, but device complexity increases
Solution Approach 1:
The second suction member is designed with multi-functionality: it can be extended outward to suction foreign substances in corner areas, and retracted inward to avoid obstacles during traveling. This universal design allows a single component to serve multiple functions, improving cleaning coverage without proportionally increasing device complexity.
Solution Approach 2:
The second suction member is designed to be movable relative to the main body, capable of extending outward to suction foreign substances in corner areas and retracting inward to avoid obstacles during traveling. This dynamic design allows the suction device to adapt to different cleaning scenarios, improving cleaning coverage without permanently increasing structural complexity.
