Cordless Cleaner Battery Layout for Longer Runtime and Steerability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Upright-type cleaners suffer from limited usage time and user fatigue due to the weight of batteries and motors, which also affect steerability and comfort during cleaning.
Innovation Solution
Incorporating an additional battery unit that is slidably coupled to the extension duct, allowing it to be positioned closer to the ground or main body for improved steerability and stability, while a primary battery unit is integrated with the handle for easier grip and reduced wrist strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If an additional battery is added to extend usage time, then the cleaning duration is improved, but the weight of the cleaner increases causing user fatigue
Solution Approach 1:
The battery system is segmented into a first battery unit integrated with the handle and a second battery unit that can be detachably coupled to the extension duct, allowing the total battery capacity to be divided into manageable portions that can be independently positioned
Solution Approach 2:
The second battery unit is coupled to the extension duct which extends from the main body, utilizing the longitudinal dimension of the cleaner to distribute weight away from the user's hand and toward the lower portion of the device
2Device complexity
If the battery and motor are located in the main body, then the structure is simplified, but the user feels increased fatigue due to weight concentration
Solution Approach 1:
The second battery unit is extracted from the main body and coupled to the extension duct, separating the battery mass from the main body to redistribute weight and reduce the torque burden on the user's wrist and arm
3Stability of the object's composition
If the storage battery is always located at the lower side, then the structure is stable, but the steerability of the cleaner deteriorates
Solution Approach 1:
The second battery unit is designed to be detachably and repositionably coupled to the extension duct, allowing dynamic adjustment of its position along the duct to optimize the balance between stability and steerability based on operational needs

AI summary
According to an embodiment of the present disclosure, provided is a cleaner which comprises: a main body having a cylindrical shape; a cyclone unit which is provided inside the main body so as to separate dust from air suctioned into the main body; an extension duct which communicates with the cyclone part and extends from the main body; a suction nozzle which is coupled to the extension duct and suctions dust; a first battery unit which extends from the main body and supplies electric power so that the cyclone unit can suction air; and a second battery unit which supplies electric power to the cyclone unit and is slidably coupled to the extension duct. According to an embodiment of the present disclosure, the usage time of the cleaner can be increased, and the fatigue that a user feels can be minimized even when the usage time is increased.
