Solution Overview
Problem
Robot cleaners struggle to effectively clean areas adjacent to walls during autonomous travel, as existing zigzag driving patterns often leave uncleaned areas, leading to user dissatisfaction.
Innovation Solution
A cleaner with a suction unit on its front side and a control unit that adjusts its movement pattern to ensure thorough cleaning by spacing apart from the wall, rotating, and re-contacting at different points to cover the entire wall area, using sensors to detect contact and uncleaned areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the suction unit is installed only on the front side of the main body, then the device complexity is reduced, but the cleaning coverage of wall-adjacent areas becomes insufficient
Solution Approach 1:
The patent implements dynamic adjustment of the main body's distance from the wall during cleaning operations. The control unit dynamically controls the driving unit to adjust the spacing between the main body and wall based on real-time sensor feedback, allowing the front suction unit to effectively cover wall-adjacent areas that would otherwise be inaccessible with a fixed positioning system.
2Productivity
If zigzag driving pattern is used, then the productivity is improved, but the cleaning quality of wall-adjacent areas deteriorates
Solution Approach 1:
The patent employs sensor-based feedback mechanisms to detect the main body's contact with or distance from walls during zigzag driving. The control unit processes this feedback information and dynamically adjusts the driving pattern, modifying the zigzag motion parameters in real-time to ensure the suction unit maintains optimal positioning for cleaning wall-adjacent areas while preserving overall cleaning efficiency.
3Stability of the object's composition
If the main body maintains constant distance from the wall, then the stability of the object's composition is improved, but the cleaning performance of wall areas deteriorates
Solution Approach 1:
The system transitions from static constant-distance positioning to dynamic distance adjustment. The control unit continuously modifies the main body's distance from the wall based on sensor feedback, enabling the suction unit to adapt its position for optimal wall-adjacent area cleaning while maintaining overall system stability through controlled, feedback-driven adjustments.
