Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional additive manufacturing methods are used to construct complex objects layer by layer, then manufacturing flexibility and design freedom are improved, but structural integrity and manufacturing efficiency deteriorate due to the need for extensive milling and cutting operations
Solution Approach 1:
The manufacturing process is segmented into two distinct phases: casting phase for creating the base structure with high structural integrity, and additive manufacturing phase for adding complex features. This segmentation allows each process to optimize for its strength - casting for structural integrity and additive manufacturing for design freedom.
Solution Approach 2:
The casting process is performed as a preliminary action before additive manufacturing. The base structure is cast first to establish the foundational structural integrity, then additive manufacturing adds complex features without compromising the already-established structural core.
2Manufacturing precision
If extensive milling and cutting operations are performed to obtain the final form, then manufacturing precision is improved, but manufacturing time and material waste increase
Solution Approach 1:
The final form is preliminarily established through casting before additive manufacturing begins. This preliminary casting action creates the base geometry with high precision, reducing or eliminating the need for subsequent milling and cutting operations that would consume time and material.
Solution Approach 2:
The method eliminates the need for traditional subtractive operations by using casting to directly create the base form. This discards the inefficient milling and cutting steps entirely, recovering manufacturing time and reducing material waste associated with removing excess material.
3Strength
If casting is used to create the base structure, then structural integrity is improved, but integration with additive manufacturing processes becomes complex
Solution Approach 1:
The system is segmented into a casting subsystem and an additive manufacturing subsystem, each optimized for its specific function. The casting subsystem handles base structure creation while the additive manufacturing subsystem handles feature addition, reducing the complexity of integrating both processes compared to a single unified system.
Solution Approach 2:
The patent introduces a coordination mechanism that acts as an intermediary between the casting process and additive manufacturing process. This intermediary manages the transition and integration between the two subsystems, simplifying the overall system complexity by providing a standardized interface for process coordination.

AI summary
A method for cast based hybrid additive manufacturing includes receiving a three-dimensional digital model file for construction of an object utilizing an additive manufacturing device. The method also includes receiving one or more additional requirements for the object and identifying, based on the three-dimensional digital model file and the one or more additional requirements for the object, a cast for the three-dimensional digital model file for integration into hybrid additive manufacturing of the object. The method also includes instructing, a secondary manufacturing device, to dispose the cast at a position with respect to a partially constructed object by the additive manufacturing device. The method also includes resuming the hybrid additive manufacturing of the partially constructed object with the cast until the construction of the object is complete.
