Docking station for robotic cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robotic vacuum cleaners require frequent emptying of dust cups, reducing user convenience due to limited debris storage capacity, and manual disposal of debris can be unsanitary.
Innovation Solution
A docking station with a filter medium that collects debris from the dust cup, forms a closed bag when full, and deposits it into a collection bin, allowing for multiple cleaning cycles before emptying and providing a sanitary disposal process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the dust cup size is increased to extend debris storage capacity, then the frequency of emptying is reduced, but the device complexity and space requirements increase
Solution Approach 1:
The system divides the debris storage function into two segments: the robot's dust cup for collection during cleaning operations and the docking station's collection bin for long-term storage. This segmentation allows the robot to maintain a compact, simple dust cup while the docking station houses a larger collection bin, resolving the contradiction between storage capacity and device complexity.
Solution Approach 2:
The docking station acts as an intermediary between the robot's dust cup and the final disposal location. It receives debris from the dust cup via automated suction, processes it through a filter medium that forms closed bags, and stores it in a collection bin. This intermediary system enables extended debris storage without requiring the robot itself to have a larger, more complex dust cup.
2Ease of operation
If manual emptying of the dust cup is required frequently, then user convenience is reduced, but the device complexity remains low
Solution Approach 1:
The system implements self-service by enabling the robot to automatically empty its dust cup at the docking station without user intervention. The automated suction mechanism and filter medium bag-forming process occur autonomously, allowing the robot to perform its own maintenance function and significantly improving user convenience.
Solution Approach 2:
The filter medium is pre-positioned in the docking station, ready to form closed bags when debris is transferred. This preliminary preparation of the filtering system allows for seamless automated emptying operations, enhancing convenience while keeping the overall system complexity manageable through pre-arranged components.
3Object-affected harmful factors
If debris is disposed of manually, then the process is simple, but sanitation is compromised due to direct contact with debris
Solution Approach 1:
The filter medium forms flexible, thin-film closed bags that encapsulate debris completely. These bags provide a sanitary barrier between the debris and the environment, preventing direct contact and improving sanitation quality. The bag-forming mechanism, while adding some complexity, uses relatively simple materials and processes to achieve significant sanitation benefits.
Solution Approach 2:
The filter medium bags are designed as disposable, low-cost components that are consumed during the automated emptying process. Each bag provides a fresh, sanitary enclosure for debris, and once used, the bag can be disposed of without requiring complex cleaning or sterilization systems, thus achieving high sanitation quality with manageable system complexity.
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 extends debris storage capacity, reducing the frequency of user intervention for emptying and enhancing sanitation by enclosing debris in individual bags within the collection bin.
Implementation Method 1
The suction motor may be configured to suction debris from the dust cup
Implementation Method 2
The filter system may include a filter medium to collect debris suctioned from the dust cup

AI summary
A docking station for a robotic vacuum cleaner may include a suction motor, a collection bin, and a filter system fluidly coupled to the suction motor. The suction motor may be configured to suction debris from a dust cup of the robotic vacuum cleaner. The filter system may include a filter medium to collect debris suctioned from the dust cup, a compactor configured to urge a first portion of the filter medium towards a second portion of the filter medium such that a closed bag can be formed, and a conveyor configured to urge the closed bag into the collection bin.
