Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile cleaning robots require efficient maintenance and interaction processes, such as debris evacuation and fluid refilling, which existing docking stations often fail to facilitate effectively, especially for two-in-one mopping and vacuuming robots.
Innovation Solution
A docking station with a canister and base configuration that includes a debris bin, electrical power interface, wheel well switches, a filling spout, and storage compartments to support debris evacuation, charging, and fluid refilling, ensuring seamless interaction with mobile cleaning robots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a docking station includes multiple components for debris evacuation, tank filling, and charging, then the functionality and versatility are improved, but the device complexity increases
Solution Approach 1:
The patent combines debris evacuation, tank filling, and charging functions into a single integrated docking station unit. The base receives the robot for all three operations, and the canister houses both the debris bin and fluid tank, merging multiple maintenance functions into one unified structure that simplifies the overall system architecture.
Solution Approach 2:
The docking station is designed as a multi-functional device where the base provides charging through electrical interfaces, the canister enables debris evacuation via a debris bin, and the same canister also supports fluid refilling through a fluid tank. This universal design allows a single docking station to perform multiple maintenance operations without requiring separate specialized devices.
2Ease of operation
If the docking station includes a filling spout and fluid tank for refilling, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The docking station enables autonomous self-service refilling operations. The robot autonomously docks with the base, aligns its fluid receptacle with the filling spout, and receives cleaning fluid automatically from the fluid tank without human intervention. This self-service capability simplifies operation while the automated docking and alignment mechanisms manage the added complexity.
3Productivity
If the base receives the robot for multiple maintenance operations, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The docking station is segmented into functionally distinct components: the base handles charging and provides structural support, while the canister mounted on the base contains the debris bin for evacuation and the fluid tank for refilling. This segmentation allows each component to specialize in specific functions, improving operational efficiency while organizing complexity into manageable modular units.
