Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vacuum apparatus is used to evacuate non-sintered material powder, then powder removal is achieved, but the process requires burden and time
Solution Approach 1:
The invention extracts the non-sintered material powder from the molding table surface by lowering the molding table to a predetermined position where the powder discharging section is located, enabling direct discharge of powder without using vacuum apparatus
Solution Approach 2:
The system uses its own structural components (molding table, powder discharging section, chute) to achieve powder removal autonomously, eliminating the need for external vacuum apparatus and reducing operational burden
2Ease of manufacture
If vacuum apparatus is used to evacuate non-sintered material powder, then powder removal is achieved, but the process is labor-intensive
Solution Approach 1:
The invention extracts the powder removal function from the complex vacuum apparatus system and integrates it into the molding table's positional control system, simplifying the operation to merely lowering the table to a predetermined position
Solution Approach 2:
The system performs powder removal using its inherent structural elements (molding table, powder discharging section, chute), eliminating the need for external vacuum equipment and reducing operational complexity
