Stick-Coupled Vacuum Cleaner with Separable Automatic and Manual Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional separable robot cleaners are cumbersome due to the weight of the hand-type cleaner, which includes a suction motor and dust container, and do not allow users to manually move the cleaning unit while it is automatically cleaning, limiting user flexibility and convenience.
Innovation Solution
A cleaning apparatus with a separable stick unit that can be coupled with a cleaning unit, enabling the cleaning unit to automatically move when the stick unit is detached and allowing manual movement when coupled, featuring a transport device with wheels and motors, a lifting mechanism to reduce friction, and a power supply system that connects batteries in series for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hand type cleaner includes a suction motor and dust container, then cleaning functionality is improved, but weight increases causing user inconvenience
Solution Approach 1:
The cleaning apparatus is divided into a main body unit (containing suction motor and dust container) and a separate hand-type cleaner unit. This segmentation allows the heavy components to remain in the main body while the hand-held portion remains lightweight for user comfort.
Solution Approach 2:
The suction motor and dust container are extracted from the hand-type cleaner and placed in the main body unit. This extraction eliminates the weight burden on the user while maintaining cleaning functionality in the main body.
2Extent of automation
If the hand type cleaner is mounted on the body, then automatic cleaning is enabled, but manual movement by user becomes impossible
Solution Approach 1:
The coupling between the hand-type cleaner and main body is made dynamic and reversible. The hand-type cleaner can be mounted on the main body for automatic cleaning operations, and detached when manual movement is required, providing operational flexibility.
Solution Approach 2:
The operational mode of the cleaning apparatus can be changed by adjusting whether the hand-type cleaner is coupled or detached. This parameter change (coupled/detached state) switches between automatic and manual operation modes.
3Stability of the object's composition
If the transport device has wheels in contact with floor surface, then automatic movement is stable, but friction increases requiring more effort for manual movement
Solution Approach 1:
A lifting device is provided that can lift the main body unit off the floor surface by counteracting gravity. When the hand-type cleaner is detached, the lifting device raises the main body, reducing wheel-floor contact and friction for easier manual movement.
Solution Approach 2:
The contact state between wheels and floor is made dynamic. The lifting device can adjust the height of the main body, changing from a low-friction state (lifted) during manual movement to a stable state (contacting floor) during automatic operation.

AI summary
A cleaning apparatus is provided. The cleaning apparatus includes a cleaning unit including a power consumption unit and a stick unit with which the cleaning unit is coupled and which allows the cleaning unit to move in a state of being gripped by a user. The cleaning unit includes a first coupling portion, and the stick unit includes a second coupling portion separably coupled with the first coupling portion, an operation portion operable to separate the second coupling portion from the first coupling portion, and a power transfer portion for transferring an operation force of the operation portion to the second coupling portion.
