Modular Agitator Coupling Design for Robot Cleaner Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot cleaners face challenges in achieving uniform cleaning performance across different environments due to the inability to easily replace the agitator, leading to inconsistent cleaning results.
Innovation Solution
The agitator is designed with a rotating body featuring multiple coupling units with varying lengths and materials of first and second members, such as blades and brushes, which are mounted alternately to enhance cleaning performance and reduce resistance and adhesion, allowing for effective cleaning in various environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed agitator design is used in robot cleaners, then the device complexity is reduced, but the adaptability to different cleaning environments deteriorates
Solution Approach 1:
The agitator is divided into multiple independent coupling units, each capable of being selectively engaged or disengaged. This segmentation allows the robot cleaner to adapt to different cleaning environments by activating only the necessary coupling units, thereby reducing overall device complexity while maintaining high adaptability.
Solution Approach 2:
The agitator employs a dynamic coupling mechanism where coupling units can be selectively engaged or disengaged based on cleaning requirements. This dynamic configuration allows the system to adjust its structure in real-time, achieving adaptability to various environments without permanently increasing device complexity.
2Productivity
If multiple members with varying lengths and materials are mounted on the agitator, then the cleaning performance is improved, but the device complexity increases
Solution Approach 1:
Different coupling units are equipped with members of varying lengths and materials tailored to specific cleaning needs. This local quality approach ensures that each part of the agitator is optimized for its specific function, improving overall cleaning performance without requiring complete redesign of the entire agitator structure.
Solution Approach 2:
The coupling units are designed with universal mounting mechanisms that can accommodate different types of members (blades, brushes, etc.). This multi-functionality allows a single coupling unit structure to serve multiple purposes with different members, improving cleaning performance while avoiding proportional increases in device complexity.
3Adaptability or versatility
If the agitator operates independently from wheels and suction unit, then the adaptability to different regions is improved, but the device complexity increases
Solution Approach 1:
The robot cleaner system is segmented into independent functional modules: wheels for movement, suction unit for debris collection, and agitator for surface treatment. This segmentation allows each module to operate independently based on specific cleaning needs, improving regional adaptability while keeping control complexity manageable through modular architecture.

AI summary
An agitator and a robot cleaner including an agitator. The agitator includes a body configured to be rotated, a plurality of couplers formed at the body and arranged to be spaced apart from each other by a predetermined distance, and a first member and a second member coupled to any one of the couplers and configured to contact a surface to be cleaned during rotation of the body. The first member and the second member extend different lengths from the body in a radial direction.
