Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional window cleaning machines are used, then window cleaning function is provided, but wastewater cannot be effectively separated from air, resulting in water spraying phenomenon
Solution Approach 1:
The patent divides the wastewater treatment process into two distinct stages: a water-air separation unit that performs preliminary separation of wastewater from air, and a wastewater separation unit that further separates and collects wastewater. This segmentation allows each unit to specialize in specific separation tasks, improving overall separation effectiveness and preventing water spraying.
Solution Approach 2:
The patent introduces a water-air separation unit as an intermediary component between the suction nozzle and the wastewater separation unit. This intermediary performs preliminary separation, reducing the load on the wastewater separation unit and preventing unseparated wastewater droplets from being discharged with air, thereby eliminating water spraying.
2Productivity
If high-altitude window cleaning is performed manually, then window cleaning is achieved, but cleaning efficiency is low and safety is compromised
Solution Approach 1:
The patent replaces manual high-altitude window cleaning operations with an automated handheld window cleaning machine. The machine uses a suction nozzle assembly to generate negative pressure, automatically sucking up wastewater from window surfaces, thereby eliminating the need for cleaners to perform dangerous high-altitude manual operations while significantly improving cleaning efficiency.
3Device complexity
If wastewater is not effectively separated, then device structure remains simple, but cleaning effect deteriorates due to pollution of cleaned glass
Solution Approach 1:
The patent implements a segmented separation structure consisting of a water-air separation unit and a wastewater separation unit. This segmentation, while increasing device complexity, ensures effective wastewater separation and prevents pollution of cleaned glass surfaces, thereby maintaining high cleaning effect.
