Robotic Cleaner Vertical Suction Unit for Adaptive Surface Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robotic cleaners have reduced cleaning efficiency due to uniform cleaning methods applied across surfaces with varying conditions, failing to adapt suction force and structure to the specific state of the surface being cleaned.
Innovation Solution
A robotic cleaner with a movable suction unit that adjusts its position and structure in response to the surface conditions, using a support unit with rollers and a rotating brush to maintain a constant gap and improve foreign matter pickup efficiency, and a control frame to adjust height and movement range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the suction unit is positioned close to the cleaning surface, then foreign matter pickup efficiency is improved, but the inlet may contact the surface causing suction force loss
Solution Approach 1:
The suction unit is designed to be movable relative to the cleaner body in the vertical direction, allowing it to dynamically adjust its position. The elastic unit member enables the suction unit to automatically adapt its height based on surface conditions, maintaining optimal clearance for different cleaning scenarios and preventing inlet contact with the surface.
Solution Approach 2:
The gap between the suction portion and the cleaning surface is controlled as a variable parameter rather than a fixed dimension. By adjusting this parameter based on surface conditions (through elastic deformation or active control), the system optimizes both pickup efficiency and suction force stability for different cleaning situations.
2Productivity
If the suction unit maintains a fixed structure, then device complexity is reduced, but cleaning efficiency decreases on varied surfaces
Solution Approach 1:
The suction unit transitions from a fixed structure to a movable one, capable of vertical movement relative to the cleaner body. This dynamic capability allows the suction unit to adapt to varied surface conditions (carpets, hard floors, obstacles) while maintaining a relatively simple overall structure through the use of an elastic unit member.
Solution Approach 2:
The cleaner is divided into separable components: the cleaner body and the movable suction unit. This segmentation allows the suction unit to operate independently with its own movement and adjustment mechanisms, improving cleaning efficiency on varied surfaces without significantly increasing overall device complexity.
3Productivity
If the inlet is positioned close to the surface, then foreign matter suction efficiency is improved, but the structure cannot adapt to different surface conditions
Solution Approach 1:
The suction unit's vertical movement capability allows it to dynamically adjust its position relative to the cleaning surface based on detected surface conditions. The elastic unit member provides the mechanical basis for this adaptation, enabling the system to maintain optimal suction efficiency across carpets, hard floors, and uneven surfaces.
Solution Approach 2:
The clearance distance between the suction inlet and the cleaning surface is changed as an adaptive parameter rather than a fixed value. This parameter adjustment based on surface conditions enables the system to maintain high suction efficiency while adapting to various cleaning environments.

AI summary
The robotic cleaner includes a cleaner body that is movable and a suction unit that is movable relative to the cleaner body in a vertical direction. The suction unit includes an inlet for sucking impurities from the surface to be cleaned, and at least one support unit for spacing the inlet and the surface to be cleaned. With the configuration, the foreign substance suction efficiency from the surface to be cleaned may be improved, and a constant gap between the suction portion and the surface to be cleaned may be maintained.
