Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional technicians manually determine and set support frames, then the quality and reliability of the 3D printing process is maintained, but the device complexity and difficulty of operation increase
Solution Approach 1:
The system performs automatic support frame determination and disposal through computerized algorithms that analyze the 3D model and independently decide where support frames are needed, eliminating the need for manual technician intervention while maintaining process quality
Solution Approach 2:
The manual mechanical process of technician analysis and support frame placement is replaced with an automated computerized system that uses algorithms to determine support requirements and control the disposal mechanism, substituting human expertise with computational analysis
2Reliability
If professional technicians manually determine and set support frames, then the quality and reliability of the 3D printing process is maintained, but the productivity decreases due to time-consuming manual operations
Solution Approach 1:
The system automatically determines support frame requirements and executes disposal without requiring manual technician intervention, significantly reducing the time required for this critical step while maintaining quality through algorithmic analysis
Solution Approach 2:
The system performs support frame determination and disposal planning in advance during the digital modeling phase, before the actual 3D printing begins, allowing for optimized support placement that prevents printing defects without requiring time-consuming manual adjustments during production
3Ease of operation
If automated support frame disposal is implemented, then the ease of operation and productivity improve, but the manufacturing precision may be affected
Solution Approach 1:
The automated system uses computerized algorithms to precisely calculate support frame locations and control the disposal mechanism with high accuracy, replacing manual placement with programmable precision that ensures correct support positioning
Solution Approach 2:
The system incorporates feedback mechanisms that monitor the support frame disposal process and adjust parameters to ensure precise placement, using real-time data from the 3D model analysis to verify that support frames are positioned correctly according to the calculated requirements

AI summary
A method, an apparatus and a computer readable medium for producing a prototype diagram of a three dimensional (3D) object are provided. In the method, an object in a 3D diagram is scanned to determine transections and intersections at which each of the transections overlaps with the object are determined in order. Then, whether each of the intersections is supported on a neighbor transection of the transection is determined. If the intersection is not supported on the neighbor transection, a support frame is disposed on the location of the intersection between the transection and the neighbor transection. At last, all the transections are combined to produce a prototype diagram of the object.
