1Extent of automation
If automated fabrication systems generate fabrication plans from digital models with many possible valid outcomes, then the system achieves minimal human intervention, but the complexity of selecting an appropriate fabrication plan increases significantly
Solution Approach 1:
The system transforms the fabrication plan selection problem by changing the parameter space from evaluating multiple valid outcomes to scoring based on feasibility metrics. The scoring mechanism assigns numerical values to different plan attributes, converting a complex qualitative selection process into a quantitative optimization problem that can be solved automatically.
Solution Approach 2:
The patent replaces manual evaluation and selection of fabrication plans with an automated scoring mechanism. Instead of human experts manually assessing each possible fabrication plan, the system uses computational algorithms to automatically score and rank plans based on predefined criteria, substituting mechanical human judgment with automated computational evaluation.
2Reliability
If the fabrication system evaluates all possible end results to ensure feasibility, then the reliability of the fabrication plan increases, but the time required to generate the fabrication plan increases significantly
Solution Approach 1:
The scoring mechanism evaluates only the most critical feasibility aspects of each fabrication plan rather than exhaustively analyzing all possible outcomes. By focusing on key scoring dimensions, the system achieves sufficient reliability without the computational burden of complete evaluation, applying partial action to the most important plan attributes.
Solution Approach 2:
The system performs preliminary scoring and filtering of fabrication plans before detailed evaluation. By pre-assessing plans based on scoring criteria, the system eliminates clearly infeasible options early in the process, reducing the time required for subsequent detailed feasibility analysis while maintaining overall plan reliability.
3Manufacturing precision
If the fabrication system performs detailed monitoring and evaluation of each task execution, then the manufacturing precision increases, but the computational resources and time required increase
Solution Approach 1:
The monitoring system applies different levels of evaluation detail to different tasks based on their importance and risk profile. Critical tasks receive detailed monitoring and evaluation, while less critical tasks receive streamlined assessment. This local differentiation of quality in monitoring ensures manufacturing precision for important operations while reducing computational resource consumption overall.
