Robot Cleaner Collection Module for Large Debris and Dust Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot cleaners struggle to efficiently remove relatively large-sized or heavy foreign matter during mopping operations, as it tends to remain on the floor due to not clinging to the mop, and also face issues with micro-scale foreign matter being blown away by air flow, reducing the effectiveness of the cleaning performance.
Innovation Solution
The robot cleaner incorporates a sliding module with a collection portion that collects foreign matter, featuring a blocking portion and auxiliary collection member to prevent separation during turns and rearward movement, along with an air channel and fan to enhance mopping efficiency and prevent micro-scale matter from being blown away.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional robot cleaner performs a mopping operation with a mop, then micro-scale foreign matter can be removed, but relatively large-sized or heavy foreign matter remains on the floor because it does not easily cling to the mop surface
Solution Approach 1:
The cleaning system is divided into two functional segments: a mop unit for removing micro-scale foreign matter through contact mopping, and a collection portion with a space for collecting relatively large-sized or heavy foreign matter that does not cling to the mop. This segmentation allows each component to specialize in removing specific types of foreign matter, thereby resolving the contradiction between cleaning thoroughness and foreign matter removal efficiency
Solution Approach 2:
The sliding module is designed to perform multiple functions: it supports the body of the robot cleaner, enables forward movement, and incorporates both a mop unit for micro-scale foreign matter removal and a collection portion for large foreign matter collection. This multi-functionality allows a single module to address both cleaning thoroughness and foreign matter removal efficiency simultaneously
2Productivity
If the robot cleaner moves forward with the mop in contact with the floor, then foreign matter is collected at the front end of the contact region, but the foreign matter separates from the mop when the robot cleaner turns or moves rearward
Solution Approach 1:
The foreign matter collection function is extracted from the mop unit and placed into a separate collection portion with a defined space. The collection portion includes a blocking portion that prevents foreign matter from separating when the robot cleaner turns or moves rearward. This extraction resolves the contradiction by providing a dedicated collection mechanism that maintains reliable foreign matter retention while preserving the productivity of foreign matter collection
Solution Approach 2:
The collection portion acts as an intermediary between the mop unit and the robot cleaner body. It receives foreign matter from the mop unit during forward movement and prevents its separation during turning or rearward movement through the blocking portion. This intermediary structure resolves the contradiction between foreign matter collection capability and retention reliability
3Ease of operation
If air flows from the front end of the contact region along the circumference, then the mopping operation can proceed, but micro-scale foreign matter flies away without clinging to the mop
Solution Approach 1:
The air flow that was causing micro-scale foreign matter to fly away is converted into a beneficial force by positioning the air inlet at the rear end of the sliding module. The air flow now moves from rear to front, creating a气流 that pushes micro-scale foreign matter toward the mop unit rather than allowing it to escape. This converts the harmful effect of air flow into a beneficial force that enhances micro-scale foreign matter removal performance while maintaining mopping operation continuity

AI summary
Disclosed are a robot cleaner and a maintenance device for the same. The robot cleaner includes a body, a traveling module for moving the body, a bottom portion disposed in front of the traveling module for sliding along a floor when the body is moved, and a collection portion disposed in front of the bottom portion, the collection portion having therein a space for collecting foreign matter on the floor. The maintenance device includes a suction port configured to be inserted into the collection portion and a suction channel for guiding the movement of the air suctioned through the suction port.
