Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If molding waste products are collected and used as-is for recycling treatment, then the recycling process is simple, but the molding waste products are entangled with each other leading to low recycling efficiency
Solution Approach 1:
The patent applies mechanical vibration through a vibration transport bed to separate entangled molding waste products. The vibration frequency is controlled within 1 to 1,000 Hz to effectively disentangle the waste products while maintaining a relatively simple recycling process structure.
2Productivity
If molding waste products are vibration-transported to separate entanglement, then recycling efficiency is improved, but the process complexity increases
Solution Approach 1:
The patent introduces a vibration transport bed that uses mechanical vibration at 1 to 1,000 Hz to separate entangled molding waste products. This approach improves recycling efficiency by effectively disentangling waste products while adding only one major equipment component to the recycling process.
Solution Approach 2:
The patent optimizes specific parameters including vibration frequency (1 to 1,000 Hz), supply rate (5 to 100 g/sec), and amount of waste product composition supplied (100 to 5,000 g/m) to achieve effective separation while maintaining process efficiency and minimizing unnecessary complexity.
3Speed
If high supply rate is used in vibration transport bed, then processing speed increases, but entanglement separation effectiveness decreases
Solution Approach 1:
The patent establishes an optimized supply rate range of 5 to 100 g/sec for the vibration transport bed. This parameter optimization ensures that waste products are fed at a rate that allows effective separation by vibration while maintaining high processing speed and recycling efficiency.
