Solution Overview
Problem
Conventional glass-wiping robots face inefficiencies when cleaning small glasses due to insufficient turning space, leading to prolonged operation times and reduced efficiency in -shaped cleaning modes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the glass-wiping robot uses -shaped cleaning operation mode on small glass, then the cleaning coverage is complete, but the turning time increases significantly reducing working efficiency
Solution Approach 1:
The patent implements dynamic operation mode switching based on real-time detection of glass dimensions and robot position. The control unit adjusts the cleaning pattern from fixed -shaped mode to adaptive modes (linear, U-shaped, or combined patterns) according to the detected glass size, thereby optimizing the balance between cleaning coverage and turning time for different glass areas.
Solution Approach 2:
The system changes operational parameters including cleaning path, turning angles, and movement speed based on detected glass dimensions. For small glass areas, the robot modifies its path planning to minimize turning operations while ensuring complete coverage, directly addressing the time loss issue in traditional fixed-mode operation.
2Productivity
If the glass-wiping robot uses -shaped cleaning operation mode on large glass, then the cleaning coverage is complete, but the cleaning time increases reducing working efficiency
Solution Approach 1:
The patent divides the large glass surface into multiple cleaning zones and implements segmented cleaning strategies. For large glass areas, the robot performs initial large-area cleaning followed by targeted edge cleaning, breaking down the overall task into efficient stages that reduce total cleaning time while maintaining complete coverage.
Solution Approach 2:
The control unit dynamically adjusts cleaning parameters including speed, path, and operation mode based on real-time position and glass size detection. This dynamic adaptation allows the robot to optimize cleaning efficiency for large surfaces by reducing unnecessary movements and turns compared to fixed -shaped patterns.
3Productivity
If the glass-wiping robot detects glass size using rangefinder and implements adaptive operation modes, then the working efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent employs a multi-functional control unit that integrates rangefinder data processing, glass size classification, operation mode selection, and real-time path planning. This universal controller handles multiple functions within a single system module, achieving adaptive operation without proportionally increasing overall device complexity.
Solution Approach 2:
The system implements feedback mechanisms where the rangefinder continuously detects glass dimensions and the control unit adjusts operation modes based on this feedback. This closed-loop control enables efficient adaptive operation while keeping the control architecture manageable through systematic feedback processing rather than complex open-loop programming.
