Robot cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot cleaners require additional electronic components and circuit designs in the charging base, along with synchronized microcomputers, which increase manufacturing costs and complexity.
Innovation Solution
A robot cleaner design that uses only the control unit of the cleaning robot to replace batteries, eliminating the need for a separate control unit and driving motor in the charging base, and instead uses the cleaning robot's driving motor for battery replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a separate control unit and driving motor are installed in the charging base for automatic battery replacement, then the battery replacement automation is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the control functions and driving mechanisms from the charging base into the cleaning robot itself. The cleaning robot's control unit now manages the entire battery replacement process, and its driving motor powers the mechanical components in the charging base, eliminating the need for separate control and motor systems in the charging base.
Solution Approach 2:
The cleaning robot performs self-service by using its own control unit and driving motor to execute the battery replacement process. The robot autonomously positions itself, triggers the battery swap mechanism, and manages the replacement without requiring external control or power assistance from the charging base.
2Reliability
If microcomputers in the cleaning robot and charging base are synchronized for coordinated operation, then the operational reliability is improved, but the device complexity and synchronization requirements increase
Solution Approach 1:
The patent extracts the microcomputer control function from the charging base and consolidates it entirely in the cleaning robot. This eliminates the need for synchronization between two separate microcomputers, as only the cleaning robot's control unit makes operational decisions and coordinates the battery replacement process.

AI summary
The present disclosure relates to a robot cleaner, and more particularly, to a robot cleaner that replaces a battery charged in a charging base and a discharged battery of the cleaning robot simply by using power of a cleaning robot of the robot cleaner. According to the present disclosure, the cleaning robot of the robot cleaner may include at least two driving wheels, and the charging base may include a replacement unit mechanically connected to one of the driving wheel to replace batteries and a docking unit mechanically connected to the other of the driving wheel to dock the cleaning robot. Therefore, as the cleaning robot and the charging base are mechanically connected, there is an effect of exchanging batteries only by using a control unit and the driving motor of the cleaning robot.
