Engineering Contradiction Analysis
1Quantity of substance
If the machine size is reduced for low-capacity models, then the machine becomes more suitable for smaller applications, but the aspect ratio between the rotor and processing cell becomes unfavorable, leading to poor mixing ratios
Solution Approach 1:
The processing cell transitions from a uniform cylindrical shape to a conically tapered shape, where the cross-sectional area varies along the axial direction. This local variation in geometry creates favorable flow patterns and mixing characteristics throughout the processing volume, ensuring efficient rotor-waste interaction even in reduced-size machines.
Solution Approach 2:
The geometric parameters of the processing cell are changed by introducing a conical taper with a specific angle (α). This parameter modification optimizes the aspect ratio between the rotor diameter and the processing cell dimensions, thereby improving the mixing ratio and processing efficiency in low-capacity models.
2Productivity
If traditional waste processing machines are used, then waste can be processed and expelled, but additional external storage equipment is required to ensure safe handling and long-lasting preservation
Solution Approach 1:
The storage function is merged with the processing machine by integrating a storage silo directly onto the machine frame. This combination eliminates the need for separate external storage equipment, reducing overall system complexity while ensuring safe and compliant waste storage.
Solution Approach 2:
The integrated storage silo serves multiple functions: it stores processed waste, maintains negative pressure to prevent contamination, and provides a sealed containment system. This multi-functional design replaces the need for multiple separate systems (processing + external storage + containment).
3Ease of operation
If known machines expel processed waste without integrated storage, then the processing function is simple, but the user must manually store waste in containment units to ensure easy handling and preservation
Solution Approach 1:
The machine performs automatic storage of processed waste in the integrated silo without requiring manual intervention. The system self-manages waste containment, maintaining negative pressure and sealed conditions automatically, thereby improving ease of operation while achieving full automation.
4Productivity
If a conically tapered processing cell is used, then mixing efficiency is improved in low-capacity models, but the structural design becomes more complex
Solution Approach 1:
The processing cell adopts an asymmetric conical geometry instead of a symmetric cylindrical shape. The taper angle (α) creates an asymmetric flow pattern that enhances mixing efficiency by improving the interaction between the rotor and waste material throughout the processing volume.
