Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional shot blasting and tribofinishing are used successively, then the surface properties and mechanical strength are improved, but the treatment time and production costs increase
Solution Approach 1:
The patent combines shot blasting and tribofinishing operations into a single integrated device. The device includes both shot blasting means for introducing residual compressive stresses and tribofinishing means for surface polishing, allowing both operations to be performed simultaneously or sequentially in one treatment cycle, thereby reducing total treatment time while maintaining mechanical strength improvements
Solution Approach 2:
The integrated device performs multiple functions: it conducts both shot blasting to improve mechanical strength and tribofinishing to enhance surface properties. This multi-functional approach eliminates the need for separate machines and operations, reducing treatment time and production costs while achieving both strength enhancement and surface finishing in a single process
2Shape
If conventional shot blasting and tribofinishing are used successively, then the surface properties are improved, but the number of operations and controls increase
Solution Approach 1:
The patent merges shot blasting and tribofinishing operations into a single integrated device with unified control. The device includes shot blasting means for stress introduction and tribofinishing means for surface polishing, both controlled from a single system, thereby reducing the number of separate operations and controls needed while achieving improved surface conditions
Solution Approach 2:
The integrated device provides universal functionality by performing both shot blasting and tribofinishing in one machine. This multi-functional design reduces operational complexity and the number of control systems required, while still achieving comprehensive surface condition improvement including polishing, burr removal, and angle rounding
3Reliability
If separate machines for shot blasting and tribofinishing are used, then each function is performed effectively, but production costs increase
Solution Approach 1:
The patent combines shot blasting and tribofinishing machines into a single integrated device, eliminating the need for multiple separate machines. This merger maintains the effectiveness of both functions while reducing equipment investment, production costs, and production line complexity
Solution Approach 2:
The integrated device achieves universal functionality by incorporating both shot blasting capabilities for mechanical strength improvement and tribofinishing capabilities for surface finishing. This multi-functional approach reduces production costs by eliminating redundant equipment while maintaining the reliability and effectiveness of both treatment functions
