Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual analysis methods are used to determine camera positions, then measurement precision can be achieved, but loss of time increases significantly
Solution Approach 1:
The patent creates a virtual copy of the physical production set in a simulated environment. This virtual model allows for rapid analysis of moiré patterns across multiple camera positions without physically moving equipment or performing manual calculations at each location, thereby maintaining measurement precision while dramatically reducing time consumption.
Solution Approach 2:
The system performs preliminary analysis in the virtual environment by pre-calculating moiré pattern probabilities for numerous camera positions before actual filming. This advance preparation identifies optimal camera locations ahead of time, eliminating the need for time-consuming on-set analysis while ensuring measurement accuracy is maintained.
2Reliability
If comprehensive analysis of all camera positions is performed, then reliability of moiré pattern avoidance is improved, but device complexity increases
Solution Approach 1:
The patent introduces a virtual simulation environment as an intermediary between the physical set and the analysis process. This intermediary layer handles the complex calculations of moiré patterns across multiple camera positions, allowing comprehensive analysis to be performed without increasing the complexity of the physical production equipment.
