Solution Overview
Problem
Existing self-moving cleaning devices face challenges in accurately aligning and docking with base stations for maintenance operations such as charging, water replenishment, and cleaning, which affects the efficiency and reliability of these processes.
Innovation Solution
A modular base station design incorporating a mounting bracket that integrates the homing signal transmitter, water replenishment connector, and charging docking assembly, ensuring precise alignment and reducing assembly complexity through limiting portions and a unified mounting system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate mounting structures are used for homing signal transmitter, water replenishment connector, and charging assembly, then each component can be independently installed and maintained, but the alignment accuracy between docking components deteriorates and assembly complexity increases
Solution Approach 1:
The patent combines the homing signal transmitter, water replenishment connector, and charging assembly into a single integrated mounting bracket structure. This unified bracket ensures precise relative positioning of all docking components while maintaining modular replaceability, thus resolving the contradiction between independent maintenance and alignment accuracy.
Solution Approach 2:
The mounting bracket serves multiple functions simultaneously: it mounts the homing signal transmitter, supports the water replenishment connector, and positions the charging assembly. This multi-functional design eliminates the need for separate mounting structures while ensuring consistent alignment across all components.
2Ease of repair
If multiple separate mounting structures are used for different docking components, then each component can be independently replaced, but the overall assembly complexity and number of parts increases
Solution Approach 1:
The patent merges multiple mounting functions into a single integrated mounting bracket that holds all docking components. This reduces the total number of parts and simplifies assembly while maintaining the ability to replace individual components by detaching them from the unified bracket.
Solution Approach 2:
While the mounting structures are merged, the docking components themselves remain segmented and independently replaceable. The unified bracket provides a common mounting platform, but each component (homing signal transmitter, water connector, charging assembly) can be individually detached and replaced without affecting the others.
3Manufacturing precision
If precise alignment mechanisms are implemented for docking components, then docking accuracy improves, but the assembly complexity and manufacturing difficulty increases
Solution Approach 1:
The patent achieves precise alignment by combining all docking components into a single integrated mounting bracket. The relative positions of all components are fixed during bracket manufacturing, eliminating the need for complex alignment mechanisms. The bracket itself becomes the alignment reference, simplifying both manufacturing and assembly.

AI summary
A base station (200) and a cleaning robot system. The base station (200) comprises a base station housing (210), a mounting support (250), a pile searching signal transmitter (251), a clean water tank (213), and a water replenishment connector (2114). The mounting support (250) is detachably connected to the base station housing (210); both the pile searching signal transmitter (251) and the water replenishment connector (2114) are connected to the mounting support (250), and the pile searching signal transmitter (251) is used for transmitting a pile searching signal to be received by a self-propelled cleaning device (100); and the clean water tank (213) is mounted on the base station housing (210), an inlet of the water replenishment connector (2114) is connected to the clean water tank (213), and an outlet of the water replenishment connector (2114) is connected to a water injection port of the self-propelled cleaning device (100). The mounting tolerance between the pile searching signal transmitter (251) and the water replenishment connector (2114) can be reduced, thereby facilitating the alignment and water replenishment operations of the self-propelled cleaning device (100) and the base station (200).
