Engineering Contradictions & Design Principles
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, sensors, and control systems that enable it to clean windows independently without human intervention. The robot can autonomously move across the window surface, detect edges and hazards, adjust its position, and complete cleaning tasks without requiring operators to manually handle dangerous high-building window cleaning operations.
2Reliability
If autonomous cleaning robots are used for high buildings, then safety is improved, but cost and complexity increase
Solution Approach 1:
The autonomous cleaning robot is divided into functional modules including a cleaning mechanism module, navigation module, control module, and power supply module. Each module performs a specific function and can be independently optimized or replaced. This modular architecture reduces overall system complexity by allowing separate development and testing of individual components while maintaining safe autonomous operation.
3Reliability
If autonomous cleaning robots are used for high buildings, then safety is improved, but cost increases
Solution Approach 1:
The cleaning robot is designed with multi-functional capabilities that allow it to perform various window cleaning tasks using a single integrated platform. The robot can adapt to different window sizes and configurations, perform both cleaning and hazard detection functions, and serve multiple building types. This universality reduces manufacturing costs by eliminating the need for multiple specialized devices for different cleaning scenarios.
4Reliability
If feedback control mechanism is added, then safety and hazard avoidance are improved, but device complexity increases
Solution Approach 1:
The robot incorporates sensors that continuously monitor vacuum pressure, edge proximity, and surface conditions, feeding this information back to the control system. When hazards or dangerous conditions are detected through vacuum pressure changes or sensor inputs, the control system automatically adjusts the robot's direction and movement to avoid these conditions. This feedback mechanism enables safe autonomous operation while maintaining manageable control complexity through automated decision-making algorithms.

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.
