Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spraying assembly uses a complex rod unit with multiple components (shaft, annular sheet, circular fitting element, internal bushing, external bushing, screw nut), then the assembly can achieve proper structural function, but the manufacturing becomes troublesome and fabrication costs increase
Solution Approach 1:
The patent merges the shaft, annular sheet, circular fitting element, internal bushing, external bushing, and screw nut into a single integrated impeller component. This consolidation eliminates multiple separate parts and assembly steps, directly reducing manufacturing complexity and fabrication costs while maintaining the structural function of water spraying.
Solution Approach 2:
The integrated impeller component performs multiple functions simultaneously: it serves as the rotational shaft, provides bearing surfaces through the internal and external bushings, includes the annular sheet for water flow, and incorporates the circular fitting element for mounting. This multi-functionality reduces the number of components needed, simplifying both manufacture and assembly.

This consolidation eliminates multiple separate parts and assembly steps, directly reducing manufacturing complexity and fabrication costs while maintaining the structural function of water spraying.
3Productivity
If the shaft is used in the spraying assembly, then water spraying function is achieved, but the shaft is prone to breaking when dropped and fracturing due to overheating
Solution Approach 1:
The patent merges the shaft, annular sheet, circular fitting element, internal bushing, external bushing, and screw nut into a single integrated impeller component. This consolidation eliminates multiple separate parts and assembly steps, directly reducing manufacturing complexity and fabrication costs while maintaining the structural function of water spraying.
Solution Approach 2:
The integrated impeller component can be manufactured from composite materials or heat-resistant alloys that combine the necessary mechanical strength for water spraying with thermal resistance to prevent overheating fracture. This material selection addresses the durability issue while maintaining productivity.
4Ease of manufacture
If the spraying assembly is simplified with fewer components, then manufacturing becomes easier and costs decrease, but structural strength and heat dissipation may be reduced
Solution Approach 1:
The patent merges the shaft, annular sheet, circular fitting element, internal bushing, external bushing, and screw nut into a single integrated impeller component. This consolidation eliminates multiple separate parts and assembly steps, directly reducing manufacturing complexity and fabrication costs while maintaining the structural function of water spraying.
