Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical waste removal methods are used, then the structure remains simple, but waste discharge completeness deteriorates when dealing with thick and hard materials
Solution Approach 1:
The patent applies pneumatic principles by introducing compressed air through air passages and blowing holes in the mold blocks. This pneumatic system creates strong airflow that effectively removes waste materials, particularly thick and hard waste that mechanical methods alone cannot discharge completely, thereby improving waste discharge completeness while maintaining relatively simple mold structure
Solution Approach 2:
The patent combines mechanical waste removal (through the rotating mold structure) with pneumatic assistance (through compressed air blowing). This merging of mechanical and pneumatic systems creates a hybrid waste discharge mechanism that leverages the advantages of both approaches to achieve more complete waste removal
2Productivity
If compressed air blowing is added to improve waste discharge, then waste removal efficiency improves, but device complexity increases
Solution Approach 1:
The patent integrates pneumatic components (air passages, blowing holes, compressed air source) directly into the mold structure. This allows compressed air to be delivered precisely where needed through the rotating mold blocks, significantly improving waste discharge efficiency by creating strong airflow that propels waste away from the cutting area
Solution Approach 2:
The mold structure serves multiple functions: it performs the primary cutting function, provides mechanical waste removal through rotation, and delivers pneumatic assistance through integrated air passages and blowing holes. This multi-functionality improves waste discharge efficiency without requiring a completely separate waste removal system

Function Achieved in This Case
The solution enhances waste discharge efficiency by using a simple yet effective structure that complements mechanical waste removal with pneumatic assistance, ensuring complete waste removal and minimizing disruptions to subsequent production processes.
Implementation Method 1
The circumferential surface of the round knife mold is convex and extends with the product waste similar to the shape of the top of the block, the waste from the top of the material belt is in the shape of the top of the block and includes a number of blowing holes, the use of compressed air is blown through the system to blow out the waste
