Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional stationary nozzles are used for cleaning the drain area, then the cleaning system is simple in structure, but the cleaning quality is insufficient and requires excessive cleaning fluid
Solution Approach 1:
The patent applies the dynamics principle by transforming the stationary nozzle into a rotating nozzle that can dynamically sweep across the drain area. The rotating nozzle is driven by cleaning media pressure and rotates around the spindle, allowing a single nozzle to cover the entire drain area systematically. This dynamic motion enables complete surface coverage with reduced cleaning fluid consumption while maintaining high cleaning quality.
2Productivity
If conventional stationary nozzles are used for cleaning, then the device complexity is low, but the cleaning process takes excessive time
Solution Approach 1:
The rotating nozzle mechanism introduces dynamic motion to the cleaning system, enabling rapid coverage of the entire drain area. The nozzle rotates during cleaning operation, systematically sweeping across all surfaces to eliminate shadow areas and ensure complete cleaning. This dynamic approach significantly reduces cleaning time compared to stationary nozzles, justifying the increased device complexity.
Solution Approach 2:
The patent utilizes pneumatic and hydraulic principles by using pressurized cleaning media to drive the rotation of the nozzle. The cleaning media is supplied through the spindle and locking ring to the rotating nozzle, which rotates under the pressure of the cleaning fluid. This self-driven rotation mechanism reduces the need for additional mechanical drive components, balancing device complexity with improved productivity.
3Area of stationary object
If conventional nozzles are used for cleaning, then the cleaning media distribution is simple, but the coverage is insufficient and creates shadow areas
Solution Approach 1:
The rotating nozzle systematically sweeps across the entire drain area, ensuring complete coverage of all surfaces including previously shadow areas. The rotation motion allows the cleaning media to reach all regions of the drain area uniformly, eliminating the coverage gaps that occur with stationary nozzles. This dynamic coverage approach maximizes the effective cleaning area.
Solution Approach 2:
The cleaning media itself serves dual functions: it provides the cleaning action and simultaneously drives the rotation of the nozzle. The pressurized cleaning fluid flows through the spindle and locking ring to reach the nozzle, where it both propels the rotation and performs the cleaning function. This self-service mechanism simplifies the media distribution system while achieving complete surface coverage.
