Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If graphite powder is discharged through a hopper without vibration assistance, then the structure is simple, but powder clustering occurs near the discharge port reducing discharge efficiency
Solution Approach 1:
The patent applies mechanical vibration through a vibration transmission unit that transmits vibrations to the mesh plate and guide members. This vibration prevents graphite powder from clustering near the discharge port by keeping particles separated and moving, thereby maintaining high discharge efficiency without requiring complex additional mechanisms
Solution Approach 2:
The mesh plate serves as an intermediary element between the hopper and discharge port. It transmits vibrations effectively to the powder while maintaining a relatively simple structure. The guide members also act as intermediaries to channel powder smoothly with vibration assistance, resolving the contradiction between simplicity and efficiency
2Speed
If graphite powder is discharged without vibration, then the apparatus structure is simple, but the discharge speed is reduced due to powder clustering
Solution Approach 1:
The vibration transmission unit generates mechanical vibrations that are transmitted through the mesh plate and guide members to the graphite powder. This vibration prevents particle aggregation and maintains high discharge speed by keeping the powder flowing smoothly through the discharge port
Solution Approach 2:
The vibration transmission operates periodically to maintain consistent powder flow. This periodic vibration ensures that powder clustering is continuously prevented, maintaining steady discharge speed without requiring continuous complex mechanical intervention
