Rotating Cleaner Sensor for Lateral Obstacle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic cleaners have limited detection ranges due to fixed sensing units, making it difficult to recognize obstacles positioned laterally, which restricts their ability to navigate and clean effectively in wider areas.
Innovation Solution
The cleaner is equipped with a rotatable sensing unit and a rotation module that allows the sensing unit to pivot relative to the dust container cover, enabling it to detect obstacles in both the left and right directions, thereby expanding its detection range and improving navigation and cleaning capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensing unit is fixed in front of the cleaner main body, then the structure is simple and stable, but the detection range is limited and lateral obstacles cannot be recognized
Solution Approach 1:
The sensing unit is made rotatable relative to the cleaner main body through a rotation module, allowing it to dynamically change its detection direction. The rotation module includes a rotation shaft and rotation driving unit that enable the sensing unit to rotate left and right, transforming it from a static to a dynamic detection system that can adapt to different detection needs while maintaining structural stability through controlled mechanical rotation
2Device complexity
If the sensing unit is fixed in the movement direction, then the device complexity is low, but it is difficult to recognize obstacles positioned in the lateral direction
Solution Approach 1:
The sensing unit incorporates a rotation module with a rotation shaft and rotation driving unit that enables dynamic left-right rotation. This allows the sensing unit to actively scan lateral areas and detect obstacles positioned in directions other than the forward movement direction, significantly improving lateral obstacle detection capability while adding only moderate complexity through the rotation mechanism
3Adaptability or versatility
If the sensing unit can rotate, then the detection range is expanded to include lateral areas, but the device complexity increases due to the rotation module
Solution Approach 1:
The rotation module uses a rotation shaft that rotates relative to the cleaner main body, driven by a rotation driving unit. This dynamic structure allows the sensing unit to achieve expanded detection range including lateral areas while keeping the added complexity manageable through a relatively simple rotational mechanism rather than a complex multi-axis system

AI summary
A cleaner may include a cleaner main body or a main body; a dust container which is accommodated in the cleaner main body; a dust container cover or a cover which covers an upper portion of the dust container; a handle which is coupled to an upper end of the dust container cover; a sensing unit or module which detects information around the cleaner main body; and a rotation module or assembly which rotates the sensing unit relatively with respect to the dust container cover.
