Engineering Contradiction Analysis
1Reliability
If traditional window cleaning methods are used, then cleaning can be performed, but it is troublesome and dangerous for high buildings
Solution Approach 1:
The cleaning robot is equipped with autonomous navigation capabilities, obstacle detection sensors, and automatic cleaning mechanisms that enable it to perform window cleaning tasks independently without human intervention, thereby eliminating the danger and trouble associated with manual high-building window cleaning
Solution Approach 2:
The patent replaces the manual mechanical cleaning system with an automated robotic system that uses electric motors, computer vision, and automated control algorithms to perform cleaning tasks, substituting human labor with an intelligent mechanical system
2Reliability
If autonomous cleaning robots are used, then safety is improved, but cost and complexity increase
Solution Approach 1:
The cleaning robot is divided into modular components including separate cleaning modules, navigation modules, power modules, and control modules that can be independently manufactured and assembled, reducing overall manufacturing complexity and cost while maintaining safety features
Solution Approach 2:
The robot is designed with multi-functional capabilities including cleaning, navigation, obstacle detection, and adaptive control that can be integrated into a single platform, reducing the need for multiple specialized devices and lowering overall system cost
3Reliability
If vacuum pressure is increased for better attachment, then cleaning reliability improves, but energy consumption increases
Solution Approach 1:
The vacuum pressure is dynamically adjusted based on real-time feedback from sensors that detect attachment force, surface conditions, and robot velocity, allowing the system to maintain reliable attachment only when necessary and reducing energy consumption during normal operation
Solution Approach 2:
The patent implements a feedback control system that continuously monitors vacuum pressure, attachment stability, and cleaning performance, automatically adjusting vacuum levels to maintain optimal attachment while minimizing energy usage through closed-loop control

AI summary
A driving mechanism for an autonomous planar surface cleaning robot is disclosed. The driving mechanism includes a first transmission component and a second transmission component spaced apart in parallel relationship relative to the first transmission component. Each of the first and second transmission components defines first and second ends and first and second sides, wherein the first sides face each other and the second sides face away from each other in a direction transverse from the direction of motion and the first and second ends are oppositely spaced along the direction of motion. Each of the first and second transmission components are independently controllable by a control unit of the autonomous planar surface cleaning robot.
