Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional laminating-printing apparatus is used without gas concentration optimization, then the apparatus structure remains simple, but the quality of laminated-printed objects cannot be further improved
Solution Approach 1:
The gas concentration optimization function is segmented into a separate concentration adjusting unit that includes purification towers and supply sections. This unit operates independently from the main laminating-printing apparatus, allowing quality improvement without significantly complicating the core printing system.
Solution Approach 2:
A concentration adjusting unit is introduced as an intermediary component between the shield gas supply and the printing chamber. This unit optimizes gas composition by removing impurities and adjusting concentrations, thereby improving print quality without requiring fundamental changes to the apparatus structure.
2Reliability
If gas concentration is optimized based on powder material, then the quality and mechanical properties improve, but the apparatus requires additional purification and supply sections
Solution Approach 1:
The system optimizes gas concentration parameters (such as oxygen content, humidity) based on the specific powder material being printed. By adjusting these gas parameters through the purification and supply sections, the mechanical properties and reliability of the printed objects are significantly improved.
Solution Approach 2:
The purification section creates an optimized inert atmosphere by removing harmful gas components (oxygen, water vapor) from the shield gas. This controlled inert environment protects the powder material during printing, preventing oxidation and degradation, thereby improving product reliability.
3Shape
If shield gas is used without purification, then the apparatus operation is simple, but shape deterioration occurs in laminated-printed objects
Solution Approach 1:
The purification towers are configured to remove impurities from the shield gas before the gas enters the printing chamber. This preliminary purification action prevents shape deterioration by ensuring that only clean, optimized gas contacts the powder material during the printing process.
Solution Approach 2:
The shield gas is transformed into a composite gas composition through the purification and supply sections. By combining purified base gas with controlled amounts of specific gas components, the system creates an optimized gas environment that maintains shape accuracy while improving overall print quality.
