Rear Debris Channel Layout for Base-Station-Compatible Cleaning Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots with debris collection boxes located in the middle or front part cannot be paired with traditional maintenance base stations, limiting their adaptability and functionality.
Innovation Solution
A cleaning robot design featuring a D-shaped housing with a debris collecting channel and a first door for opening or closing, allowing the debris collecting channel to penetrate through the rear end, enabling efficient garbage collection and compatibility with traditional base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the debris collection box is located in the middle or front part of the cleaning robot, then the robot can have better structural layout flexibility, but the robot cannot be paired with traditional maintenance base stations
Solution Approach 1:
The patent divides the debris collection system into separate functional components: a debris collection box with its own chamber, a dedicated debris collection channel, and a first door mechanism. This segmentation allows the debris collection function to be independently configured and connected to base stations, enabling compatibility across different robot layouts without requiring the entire robot structure to be redesigned.
Solution Approach 2:
The patent introduces a first door as an intermediary component between the debris collection channel and the debris collection box. This door mechanism serves as a controllable interface that can be opened or closed to facilitate debris transfer to the base station while maintaining the structural integrity of the robot body, thus enabling base station pairing regardless of the debris box position.
2Ease of manufacture
If the debris collection box is placed in the rear of the cleaning robot, then it can be paired with traditional maintenance base stations, but the structural layout flexibility is reduced
Solution Approach 1:
The patent designs the debris collection system with universal compatibility features by providing a standardized first door mechanism and debris collection channel configuration that can work with base stations regardless of whether the debris box is positioned at the front, middle, or rear of the robot. This multi-functional design allows the same base station interface to accommodate various robot layouts.
3Productivity
If a first door is added to open or close the debris collection channel, then the robot can effectively collect garbage and maintain compatibility with base stations, but the device complexity increases
Solution Approach 1:
The first door is designed to be controllable by the robot's existing control system, allowing it to automatically open when a base station is docked and close during normal operation. This self-service capability enables the door to perform its function without requiring additional manual intervention or complex external control mechanisms, thus minimizing the increase in overall system complexity.

AI summary
The cleaning robot includes a housing, a brush roller and a suction device. The housing is provided with a mounting chamber. A debris collecting chamber is communicated with the mounting chamber. The brush roller is pivotally mounted in the mounting chamber and at least a part of the brush roller protrudes from the mounting chamber. The housing is further provided with a debris collecting channel, one end of the debris collecting channel is communicated with the debris collecting chamber, the other end of the debris collecting channel penetrates through the rear end of housing, and the housing is further provided with a first door for opening or closing the debris collecting channel.
