Liquid container and autonomous cleaning robot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous cleaning robots face issues with water tank installation and disassembly, which can cause damage to sensors and internal components due to the need to invert the robot, and leaks can occur, leading to water seepage and damage.
Innovation Solution
A liquid container with a water outlet filter that regulates the water flow rate, allowing for easier installation and disassembly without inverting the robot, and a buckle and groove connection system for horizontal loading, along with an obstacle-assisting wheel for improved obstacle navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the water tank is connected to the robot at the bottom and requires inversion for installation/disassembly, then the water source can be provided for mopping, but the top of the robot and sensors are prone to collision or damage
Solution Approach 1:
The patent inverts the conventional connection approach: instead of connecting the water tank at the bottom requiring robot inversion, the connection is made at the top of the robot. The water tank has a connecting structure that interfaces with the robot body from above, eliminating the need to invert the robot and preventing damage to sensors and top components.
2Reliability
If the water tank is installed at the bottom of the robot, then the water source can be provided, but water leakage can flow into the robot through bottom gaps causing damage to internal circuits
Solution Approach 1:
The patent introduces a connecting structure as an intermediary between the water tank and robot body. This connecting structure includes sealing components that prevent water leakage from flowing into the robot's internal circuits, while still allowing for easy connection and disconnection of the water tank.
3Productivity
If a water outlet filter is added to regulate liquid flow rate, then the water flow can be controlled, but the device complexity increases
Solution Approach 1:
The water outlet filter is nested within the existing connecting structure of the water tank system. The filter element is integrated into the connecting structure, utilizing the same space and connection interface, thereby adding flow control functionality without significantly increasing overall device complexity.
