Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous cleaners face challenges in miniaturization while maintaining enhanced driving and cleaning performance, as larger power units and inlet motors increase the overall size, compromising efficiency and space utilization.
Innovation Solution
The autonomous cleaner is designed with a unique configuration where the dust collecting unit is positioned at the rear, the driving unit is laterally positioned, and the power unit is located at the rear of the dust collecting unit, allowing for a more compact design while maintaining performance through efficient element placement and innovative structural features like guide flow paths and bumper ribs.

Engineering Contradiction Analysis
1Power
If the power unit and inlet motor are increased in size to enhance driving performance and cleaning performance, then the driving and cleaning performance are improved, but the size of the entire autonomous cleaner is increased
Solution Approach 1:
The patent transitions from conventional longitudinal arrangement to a lateral arrangement of the driving unit relative to the dust collecting unit. The driving unit is positioned at a lateral side of the dust collecting unit rather than at the rear, utilizing the width dimension of the cleaner body to accommodate powerful components without increasing the overall length or volume of the device.
Solution Approach 2:
The driving unit is coupled into the second housing and positioned within the structural framework of the cleaner body, nesting the motor and transmission components within the existing housing structure. This allows the power unit to be integrated efficiently without adding external bulk to the cleaner's overall dimensions.
2Volume of moving object
If the dust collecting unit is positioned at the rear with lateral driving unit placement, then the size of the autonomous cleaner is miniaturized, but the driving performance may be compromised
Solution Approach 1:
The driving unit is positioned at a lateral side of the dust collecting unit, utilizing the width dimension rather than the length dimension. This lateral arrangement allows the cleaner to maintain a compact longitudinal profile while accommodating a sufficiently large driving unit for adequate driving performance.
Solution Approach 2:
The second housing is designed with specific structural features including a rear surface and lateral sides configured to accommodate the driving unit. The housing provides localized structural support and mounting surfaces that optimize the spatial relationship between the dust collecting unit and driving unit, ensuring both compactness and functional performance.

AI summary
An autonomous cleaner includes a body having a first housing formed at a front and a second housing formed at a rear of the first housing; a brush unit installed at the first housing and configured to sweep and collect dust from a floor; a dust collecting unit installed at the second housing and configured to store the dust inlet into the brush unit; a driving unit to drive the body and coupled to the second housing to be positioned at a lateral side of the dust collecting unit; and a power unit installed at the second housing and coupled to be positioned at a rear of the dust collecting unit. The miniaturization of the autonomous cleaner may be provided while at the same time the capacity of a dust collecting container and the capacity of a battery are increased.
