Wall-Mounted Charging Base for Robot Cleaner Ground Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot cleaners are unable to effectively clean the ground near or below their charging bases due to the charging base occupying space on the ground and the robot's tendency to avoid it during cleaning tasks.
Innovation Solution
A robot cleaner with a charging base that is fixed above the ground, allowing the robot to clean underneath by using a charging terminal configuration that includes a charging sheet extending downward and inwardly, enabling electrical connection while the robot is placed in an accommodating portion, and optionally attached to a wall for stability and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the charging base is placed on the ground, then the robot body can be charged, but the robot body cannot clean the ground near or below the charging base
Solution Approach 1:
The charging base is mounted on the vertical wall surface instead of being placed on the horizontal ground, transitioning from a two-dimensional ground plane to a three-dimensional wall-mounted position. This dimensional change allows the robot to clean the previously inaccessible area below the charging base while maintaining charging capability through the vertically extending charging sheet.
2Reliability
If the charging base occupies ground space, then stable charging connection is achieved, but cleaning of the ground below the charging base becomes impossible
Solution Approach 1:
The charging base is relocated from the horizontal ground plane to the vertical wall surface, eliminating ground occupation. The charging sheet extends downward from the wall-mounted base to maintain reliable electrical connection with the robot, achieving both stable charging and complete ground coverage for cleaning.
Solution Approach 2:
The charging sheet acts as an intermediary element that bridges the wall-mounted charging base and the robot body. It extends downward from the wall to provide continuous electrical connection, allowing the base to be mounted on the wall while maintaining reliable charging contact.
3Strength
If the robot body avoids the charging base during cleaning, then collision is prevented, but the ground near the charging base cannot be cleaned
Solution Approach 1:
By mounting the charging base on the vertical wall rather than placing it on the horizontal ground, the robot no longer encounters the base as an obstacle during cleaning operations. The robot can freely navigate the entire ground surface including areas previously blocked by the base, eliminating the need to avoid it while maintaining safe operation.

AI summary
A robot cleaner (100) and a charging base (2) thereof are provided. The robot cleaner (100) includes a robot body (1) and the charging base (2). The robot body (1) is provided with a first charging terminal. The charging base (2) is provided with a second charging terminal (21) matched with the first charging terminal. The charging base (2) is fixed above ground (200), and the charging base (2) defines an accommodating portion (24). The first charging terminal contacts the second charging terminal (21) to form an electrical connection after the robot body (1) is placed in the accommodating portion (24).
