Vacuum Cleaner Docking Station Debris Transfer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Upright vacuum cleaners face challenges in efficiently transitioning between storage and in-use positions, with debris accumulation in the dust cup leading to increased size and weight, and existing solutions do not effectively address this issue.
Innovation Solution
A docking station that alters the airflow path within the vacuum cleaner to transfer debris from the vacuum cleaner dust cup to a docking station dust cup using the suction motor's airflow, reducing the vacuum cleaner's size and weight by emptying the dust cup into the docking station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If debris is accumulated in the vacuum cleaner dust cup for later disposal, then the vacuum cleaner can maintain continuous operation, but the size and weight of the vacuum cleaner increase
Solution Approach 1:
The dust cup system is segmented into two separate containers: a first dust cup in the vacuum cleaner for active collection during operation, and a second dust cup in the docking station for accumulated storage. This segmentation allows the vacuum cleaner to maintain continuous operation by periodically emptying into the docking station, while keeping the vacuum cleaner's weight and size reduced.
Solution Approach 2:
The docking station acts as an intermediary system that receives debris from the vacuum cleaner's dust cup and transfers it to a separate storage container. This intermediary structure enables the vacuum cleaner to operate continuously without carrying all the accumulated debris, thus reducing its weight while maintaining operational duration.
2Weight of moving object
If a docking station is added to enable debris transfer, then the vacuum cleaner size and weight are reduced, but the device complexity increases
Solution Approach 1:
The system employs self-service mechanisms where the vacuum cleaner autonomously docks with the station and debris is automatically transferred from the first dust cup to the second dust cup using airflow generated by the vacuum cleaner's own suction motor. This self-service approach minimizes the need for additional complex mechanical components, manual intervention, or external power sources at the docking station, thereby reducing overall system complexity while achieving weight reduction.
3Productivity
If the dust cup volume is increased to reduce emptying frequency, then continuous operation is improved, but the vacuum cleaner size increases
Solution Approach 1:
The solution moves the additional storage capacity from the vertical dimension (increasing dust cup volume within the vacuum cleaner) to a separate spatial dimension (a second dust cup in the docking station). This dimensional transition allows the vacuum cleaner to maintain a compact size while achieving extended operational capacity through the distributed storage architecture.
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 efficiently transfers debris from the vacuum cleaner dust cup to the docking station dust cup, reducing the vacuum cleaner's size and weight, and allows for independent use of vacuum cleaning accessories.
Implementation Method 1
a suction motor configured to draw air into an air inlet of the upright vacuum cleaner such that debris deposited on a surface can be urged into the air inlet

AI summary
A docking station for a vacuum cleaner may include a receptacle configured to engage at least a portion of the vacuum cleaner such that, in response to engaging the receptacle, a vacuum cleaner flow path extending within the vacuum cleaner is transitioned from a cleaning flow path to an evacuation flow path, a suction motor of the vacuum cleaner being configured to urge air along the vacuum cleaner flow path and a docking station dust cup configured to receive debris from a vacuum cleaner dust cup of the vacuum cleaner.
