Solution Overview
Problem
Traditional window cleaning methods using suspension machines are unstable in windy conditions, leading to accidents and incomplete cleaning due to the risk of tools dropping and pedestrians being harmed, resulting in only partial water spraying to prevent accidents.
Innovation Solution
A cleaner that uses negative air pressure to attach to a plate and move across it, equipped with a pump module, driving module, and control system, allowing for controlled movement and cleaning of particles on the plate surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a suspension machine is used to clean exterior windows, then cleaning capability is improved, but stability deteriorates due to center of gravity being unstable in wind
Solution Approach 1:
The patent replaces the traditional mechanical suspension system with a magnetic field-based adhesion system. The cleaner uses magnetic attraction force to attach to the glass surface, eliminating the need for mechanical suspension structures and cables. This substitution provides stable positioning without the swing and instability problems of mechanical suspension systems.
Solution Approach 2:
The patent employs a vacuum pump to create negative pressure between the cleaner and the glass surface, forming a vacuum adhesion effect. This pneumatic mechanism enhances the attachment stability, preventing the cleaner from falling or swinging during operation, especially in windy conditions.
2Reliability
If water spraying is reduced to prevent accidents, then safety is improved, but cleaning completeness deteriorates
Solution Approach 1:
The patent replaces water-based cleaning with a magnetic adhesion system that securely attaches the cleaner to the glass surface. This eliminates the safety risk of water spraying and tool dropping while maintaining cleaning effectiveness through magnetic holding force and controlled movement.
Solution Approach 2:
The cleaner uses its own magnetic field and vacuum pressure to maintain attachment to the glass surface, making the system self-stabilizing. The magnetic adhesion and vacuum pressure automatically adjust to maintain safe and effective cleaning operation without external intervention.
3Reliability
If cleaning tools are securely attached, then safety is improved, but movement control flexibility deteriorates
Solution Approach 1:
The patent uses controllable magnetic field strength and adjustable vacuum pressure to dynamically adjust the attachment force. This allows the cleaner to maintain secure attachment for safety while enabling flexible movement control when needed, achieving both stability and operational flexibility.
Solution Approach 2:
The patent changes the parameters of magnetic field intensity and vacuum pressure to control the attachment state. By adjusting these parameters, the system can transition between strongly attached (for safety) and more flexible (for movement control) states, resolving the contradiction between secure attachment and movement flexibility.
