Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual window cleaning is used for high-altitude windows, then cleaning can be performed, but it is unsafe and requires expensive climbing equipment
Solution Approach 1:
The window cleaning system is segmented into independent components: the window frame with integrated guides remains stationary, while the wiper blade with motors and cleaning mechanisms moves independently along the guides. This segmentation allows the cleaning mechanism to be separated from the window structure, enabling safe automated operation at high altitudes without requiring climbing equipment.
Solution Approach 2:
The window cleaning system performs self-service through automated wiper blades equipped with motors that move along guides integrated into the window frame. The system includes self-contained washing liquid supply mechanisms with reservoirs and pumps, eliminating the need for manual operation and external climbing equipment, thereby ensuring safety at high altitudes.
2Productivity
If manual window cleaning is used, then cleaning can be performed, but it is laborious and requires cleaners
Solution Approach 1:
The window cleaning system performs self-service through automated wiper blades equipped with motors that move along guides integrated into the window frame. The system includes self-contained washing liquid supply mechanisms with reservoirs and pumps, eliminating the need for manual operation and external climbing equipment, thereby ensuring safety at high altitudes.
Solution Approach 2:
Manual mechanical cleaning operations are replaced with an automated electromechanical system. Motors drive the wiper blades along the guides, and electric pumps supply washing liquid, substituting human labor with automated mechanical and electrical systems that significantly improve productivity and reduce labor requirements.
3Productivity
If existing automated cleaning devices are used, then cleaning can be performed, but they lack washing liquid supply for heavy pollution
Solution Approach 1:
The washing liquid supply system is merged with the window frame structure. Reservoirs, pumps, and channels are integrated into the frame, combining the cleaning mechanism with the window structure itself. This integration provides efficient washing liquid supply for heavy pollution while avoiding separate complex external systems.
Solution Approach 2:
The window frame serves multiple functions: it provides structural support for the window and simultaneously houses the guides for wiper movement and the washing liquid supply system. This multi-functionality enables efficient cleaning of heavily polluted windows without adding separate complex systems, as the frame itself becomes part of the cleaning mechanism.
4Ease of operation
If existing automated cleaning devices are used, then cleaning can be performed, but they cannot automatically switch off
Solution Approach 1:
The control system incorporates feedback mechanisms that monitor the cleaning process and automatically switch off the device when cleaning is complete or when abnormal conditions are detected. Sensors and control circuits provide feedback to the motor controllers, enabling automated operation and shutdown without requiring complex external control systems.

AI summary
The invention relates to the field of washing and cleaning building facilities. The aim of the invention is to create an automated device for safely and efficiently cleaning the outside surfaces of windows situated at any height. The present automated window-cleaning device comprises a window frame with glazing, a raising mechanism, a cleaning fluid supply mechanism, and a control unit. The raising mechanism includes two vertical guides fastened on the outside along the edges of the window frame, parallel to one another, each vertical guide having disposed therein a toothed strip mounted on an upper and a lower toothed pulley, wherein the upper toothed pulley is connected to an electric motor. The toothed strip is encircled by an aluminium fork, to which is attached a wiper blade containing a magnet.
