Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated window cleaning machines are used, then productivity is improved, but device complexity increases and requires multiple operators
Solution Approach 1:
The robot is divided into functional modules: propulsion module with balloon wheels for movement, cleaning module with brushes and solution tank, control module with sensors and processors, and safety module with warning systems. Each module operates independently but coordinates through the central control system, enabling automated high-rise cleaning without requiring multiple operators while managing complexity through modular design
Solution Approach 2:
A remote operator controls the robot via wireless communication systems (radio frequency and infrared transmitters/receivers), serving as an intermediary between the operator and the complex automated system. This allows simplified operation of the sophisticated cleaning robot from ground level, reducing the need for multiple personnel on-site
2Ease of operation
If climbers or lift systems are used, then ease of operation is maintained, but safety deteriorates due to human factor risks
Solution Approach 1:
The robot autonomously navigates to cleaning positions using its propulsion system, self-adjusts cleaning parameters through onboard sensors that detect surface conditions, and self-monitors operational status. The automated control system eliminates human operators from hazardous high-rise environments while maintaining operational simplicity through programmable sequences and autonomous decision-making capabilities
Solution Approach 2:
Multiple sensors continuously monitor wind speed, balloon wheel position, brush contact force, and solution levels, feeding real-time data to the control system. The system automatically adjusts operations based on this feedback, maintaining safety and effectiveness without human intervention. Warning systems provide additional feedback to remote operators when intervention is needed
3Productivity
If cleaning is performed at higher elevations, then productivity is improved, but object-affected harmful factors increase due to wind exposure
Solution Approach 1:
The balloon wheels generate upward aerodynamic lift to counteract the robot's weight and maintain stable attachment to vertical surfaces. The control system continuously adjusts balloon inflation pressure to compensate for wind forces, effectively using aerodynamic counterforces to maintain position and enable productive operation at high elevations despite wind exposure

AI summary
The window cleaning robot according to the invention has an artificial intelligence-controlled moveable washing system which senses such projections as frames, moldings, composite coating materials, etc. on the facades by means of the sensors disposed thereon and which adjusts the positions of the cleaning brushes in a way to contact with the glass surface evenly. It makes the facade cleaning in high-rise buildings safer with the fans adjusting the axial thrust force according to the speed and direction of the wind in a way not to detach from the surface to be cleaned. It allows saving on time, labor force, and costs in facade cleaning. The robot permits performing the cleaning in glass surfaces and facades in a safe manner eliminating the requirement of human factor.
