Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pyrolysis treatment is performed in a chamber with heating modules, then waste gases are thermally decomposed, but powder is fixed to the chamber and heating modules causing decreased operation efficiency and durability
Solution Approach 1:
The patent extracts the harmful powder from the chamber by introducing a gas flow that carries the powder out through a discharge port. The gas flow is directed along the chamber wall to lift and remove accumulated powder, separating it from the heating modules and chamber surfaces.
Solution Approach 2:
The system uses the waste gas itself or a circulating gas within the chamber to perform the cleaning function. The gas flow serves dual purposes: maintaining the pyrolysis atmosphere and simultaneously removing powder deposits through the discharge port.
2Productivity
If powder accumulates in the chamber, then operation efficiency decreases, but adding powder collection structures increases device complexity
Solution Approach 1:
The gas flow system performs dual functions: it maintains the pyrolysis process atmosphere and simultaneously removes powder through the discharge port. This self-service approach eliminates the need for separate mechanical cleaning mechanisms, reducing device complexity while maintaining high operation efficiency.
3Ease of operation
If the chamber is shut down to remove powder, then powder management is improved, but equipment utilization decreases
Solution Approach 1:
The gas flow system operates continuously during pyrolysis treatment, constantly removing powder through the discharge port. This eliminates the need for shutdowns to manage powder accumulation, allowing continuous operation and maintaining high equipment utilization while simplifying waste management.
4Object-generated harmful factors
If additional heating is applied to prevent powder fixation, then powder generation is reduced, but energy consumption increases
Solution Approach 1:
The existing gas flow and heating system perform dual functions: conducting pyrolysis treatment and removing powder through the discharge port. No additional heating or energy input is required—the system uses its own operational parameters to prevent and remove powder fixation.
