Robotic Cleaner Evacuation Dock for Autonomous Bin Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous coverage robots face challenges in efficiently emptying debris from their bins without human intervention, limiting their operational duration and coverage area.
Innovation Solution
A cleaning system comprising a robotic cleaner, an evacuation station, and a portable vacuum, where the robotic cleaner navigates to the evacuation station, docks, and uses a compliant evacuation connector to transfer debris to the portable vacuum, which provides suction for emptying the bin, allowing the robotic cleaner to operate continuously without human interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the robotic cleaner uses a larger debris bin to cover larger areas, then the coverage area increases, but the device complexity and size increase
Solution Approach 1:
The system divides the debris storage function into two separate components: a compact bin on the robotic cleaner for active collection, and a larger portable vacuum for bulk storage. This segmentation allows the robot to maintain small size while achieving extended operational capacity through periodic emptying at the portable vacuum station.
Solution Approach 2:
The portable vacuum acts as an intermediary station between the robotic cleaner and final debris disposal. It receives debris from the robot via automated connector engagement, provides temporary bulk storage, and enables the robot to operate continuously without returning to human-operated emptying.
2Duration of action of moving object
If the robotic cleaner operates continuously without human intervention, then the duration of action increases, but the bin fills up requiring human emptying
Solution Approach 1:
The automated emptying system enables continuous operation by eliminating the interruption caused by manual bin emptying. The robotic cleaner autonomously navigates to the portable vacuum, engages the connector, and transfers debris, allowing the cleaning process to resume immediately without human intervention.
Solution Approach 2:
The robotic cleaner performs self-emptying by autonomously navigating to the portable vacuum station and engaging the automated connector system. This self-service capability removes the need for human operators to manually empty the bin, enabling truly autonomous continuous operation.
3Quantity of substance
If the robotic cleaner returns to base station to empty bin, then the bin is emptied, but the robot must travel back and forth reducing productivity
Solution Approach 1:
The emptying function is extracted from the main cleaning task and performed at a separate portable vacuum station. This allows the robotic cleaner to deposit debris quickly without the complexity of on-board processing or return trips to a fixed base station, maintaining cleaning productivity while enabling bin emptying.
4Duration of action of moving object
If the robotic cleaner uses a larger bin, then the operational time increases, but the robot size and weight increase
Solution Approach 1:
The system shifts from a single-dimension solution (larger on-board bin) to a multi-dimension solution where debris storage is distributed between a small robot bin and a larger portable vacuum station. This dimensional shift allows extended operational time without increasing the robot's volume or weight.

Function Achieved in This Case
Enables the robotic cleaner to empty its bin autonomously, extend its operational time, and cover larger areas without the need for a larger debris bin, as the portable vacuum efficiently collects and stores debris.

AI summary
A cleaning system includes a robotic cleaner and an evacuation station. The robotic cleaner can dock with the evacuation station to have debris evacuated by the evacuation station. The robotic cleaner includes a bin to store debris, and the bin includes a port door through which the debris can be evacuated into the evacuation station. The evacuation station includes a vacuum motor to evacuate the bin of the robotic cleaner.
