Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If water cooling mode is used to cool the wheel blank, then the cooling efficiency is improved, but residual water remains on the blank surface affecting inspection accuracy
Solution Approach 1:
The patent extracts and removes the harmful residual water from the blank surface using high-pressure air blowing devices positioned after the water cooling section. This separation allows the cooling function to be performed thoroughly while the drying function removes the unwanted water residue, resolving the contradiction between cooling efficiency and inspection accuracy.
Solution Approach 2:
The patent introduces high-pressure air as an intermediary substance between the water-cooled blank and the X-ray inspection process. The compressed air serves as a mediator that eliminates residual water from the blank surface without interfering with the cooling already achieved or the subsequent inspection process.
2Measurement precision
If high-pressure air is used to remove residual water, then the inspection accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into unified components: the conveyor system simultaneously transports blanks and positions them for both cooling and drying operations; the high-pressure air system serves both to blow off water and to dry the surface. This multi-functionality reduces the number of separate devices needed while maintaining inspection accuracy.
Solution Approach 2:
The patent employs pneumatic systems (compressed air supply) to achieve water removal and surface drying. This pneumatic approach is more space-efficient and mechanically simpler than alternative methods such as mechanical wiping or heating systems, thereby improving inspection accuracy without proportionally increasing device complexity.
3Ease of manufacture
If a simple structure is used for the water blowing device, then the ease of manufacture is improved, but the positioning precision deteriorates
Solution Approach 1:
The patent employs self-centering mechanisms where the blank's own geometry (such as its circular shape) works with the conveyor and positioning structures to automatically center itself during transport and processing. This self-service positioning approach achieves high positioning precision without requiring complex external positioning devices, maintaining ease of manufacture.
Solution Approach 2:
The patent creates equipotential positioning conditions where the blank is positioned in a state of mechanical equilibrium during the water blowing process. By designing the conveyor and support structures to provide uniform support and alignment forces, the system achieves precise positioning through simple structural means rather than complex active control mechanisms.
