Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional high-pressure cleaning machines use fixed outlet pressure, then the machine structure is simple, but the adaptability to different cleaning objects is poor
Solution Approach 1:
The patent implements dynamic pressure adjustment by replacing the fixed pressure mechanism with an adjustable pressure regulation system. The pressure regulating valve can be dynamically adjusted to different positions to change the outlet pressure, allowing the cleaning machine to adapt to various cleaning requirements while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent changes the pressure parameter from fixed to variable by introducing a pressure regulating valve. This valve enables continuous adjustment of the outlet pressure parameter, allowing the system to optimize performance for different cleaning objects (car at 80 Mpa, air conditioning filter at 60 Mpa, floor at 10 Mpa) without redesigning the entire machine.
2Productivity
If high-pressure cleaning machine uses high water outlet pressure, then cleaning effectiveness is improved, but risk of damage to cleaning objects increases
Solution Approach 1:
The patent applies parameter changes by enabling dynamic adjustment of the outlet pressure parameter. Users can select appropriate pressure levels based on the cleaning object: high pressure (80 Mpa) for durable surfaces like car bodies, medium pressure (60 Mpa) for air conditioning filters, and low pressure (10 Mpa) for delicate surfaces. This eliminates the harmful effect of excessive pressure while maintaining cleaning effectiveness.
Solution Approach 2:
The pressure regulating valve provides dynamic control over water outlet pressure, allowing real-time adjustment during operation. This dynamic adaptation enables the system to match pressure output to the specific requirements of each cleaning task, preventing damage to sensitive objects while ensuring thorough cleaning of robust surfaces.
3Object-affected harmful factors
If high-pressure cleaning machine uses low water outlet pressure, then safety and object protection are improved, but cleaning efficiency and effectiveness deteriorate
Solution Approach 1:
The patent resolves this contradiction by making the pressure parameter adjustable rather than fixed at low levels. The pressure regulating valve enables the system to operate at low pressure (10 Mpa) for safety when cleaning delicate objects, but can be increased to high pressure (80 Mpa) when cleaning efficiency is the priority and object damage is not a concern. This eliminates the trade-off by providing user-controlled flexibility.
