Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robotic vacuum cleaners face performance degradation due to debris accumulation in their dust cups, requiring regular emptying to maintain cleaning efficiency.
Innovation Solution
A docking station with a trash bin and suction motor that automatically evacuates debris from the robotic cleaner's dust cup into a trash bag, allowing for easy disposal and reducing the need for frequent manual emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dust cup is emptied manually at regular intervals, then cleaning performance is maintained, but user time and effort are required
Solution Approach 1:
The system enables self-service by automatically emptying the dust cup into the trash bin without user intervention. The robotic cleaner autonomously navigates to the docking station, aligns the dust cup with the trash bin opening, and uses the onboard suction motor to transfer debris, eliminating the need for manual emptying while maintaining cleaning performance
Solution Approach 2:
The docking station serves as an intermediary between the robotic cleaner and the trash bin. It provides the structural framework and suction motor that enable automatic debris transfer, mediating the interaction between the mobile cleaner and the stationary waste container to resolve the contradiction between automated emptying and space efficiency
2Ease of operation
If a separate trash bin is dedicated for robotic cleaner debris, then debris disposal is simplified, but space consumption increases
Solution Approach 1:
The patent merges the docking station and trash bin into a single integrated unit. The docking station incorporates a trash bin with sufficient capacity to receive and store debris from multiple cleaning cycles, eliminating the need for a separate dedicated trash container and reducing overall space requirements while maintaining ease of debris disposal
Solution Approach 2:
The integrated docking station performs multiple functions: it serves as the charging station for the robotic cleaner, the automatic debris disposal system, and the waste storage container. This multi-functionality consolidates what would traditionally require separate devices into one unit, addressing the space efficiency concern while preserving operational simplicity
3Productivity
If the dust cup capacity is increased, then fewer emptying cycles are needed, but the cleaner size and suction performance may be compromised
Solution Approach 1:
The system prepares for the next cleaning cycle by automatically emptying the dust cup into the trash bin during or after each cleaning task. This preliminary action ensures the dust cup is ready for immediate reuse without requiring user intervention or increasing its capacity, maintaining compact cleaner dimensions while maximizing productivity through continuous operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The docking station maintains the robotic cleaner's performance by regularly removing debris, reducing user intervention, and combining the functions of a cleaning station and trash bin for space efficiency.
Implementation Method 1
a suction motor in the docking station creates a suction force to urge the debris from the dust cup in the robotic cleaner into the trash bin of the docking station

AI summary
In an approach to a docking station for a robotic cleaner, the docking station includes a base; a trash bin having a substantially air-impermeable trash bag removably disposed thereon; a dock dirty air inlet defined in the base, the dock dirty air inlet being configured to fluidly couple to the robotic cleaner; and a dock suction motor, wherein the dock suction motor is activated after the robotic cleaner is determined to be docked with the docking station and configured to urge debris from the robotic cleaner into the trash bin.
