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, making manual cleaning inconvenient, and restrict users from manually moving the cleaning body while it is automatically cleaning.

Innovation Solution

A cleaning apparatus with a stick unit that can be coupled to a cleaning unit, allowing manual movement by a user, and includes a power transfer mechanism to supply power to the suction force generating device, enabling both automatic and manual operation modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the hand type cleaner includes the suction motor and dust container, then the cleaning function is improved, but the weight increases causing inconvenience to the user

Engineering Contradiction:
Improvecleaning functionVSAvoidweight of hand type cleaner
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The cleaning apparatus is divided into separate modules: the cleaning unit (with suction motor and dust container) can be separated from the stick unit. This allows the heavy cleaning components to be detached and placed on the floor for automatic cleaning, while the user only needs to hold the lightweight stick unit for manual guidance or operation.

Inventive Principle:
Principle #1Segmentation

2Extent of automation

If the hand type cleaner is mounted on the body, then the automatic cleaning capability is improved, but the user cannot manually move the body while cleaning

Engineering Contradiction:
Improveautomatic cleaning capabilityVSAvoidmanual movement capability
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The coupling between the cleaning unit and stick unit is made dynamic and changeable. The cleaning unit can be automatically mounted on the body for hands-free operation, or separated to allow the user to manually hold and move the stick unit. This dynamic reconfigurability enables the system to switch between automatic and manual operation modes as needed.

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.
