Innovation Solution
A simulation device that calculates and allows user designation of voxel size based on workpiece shape, tool shape, and machining accuracy, balancing display accuracy and time through a voxel size calculation unit and acceptance unit, enabling creation of simulation images with desired accuracy and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the size of the voxel is small, then the display accuracy is high, but the computation time and drawing time are long
Solution Approach 1:
The patent applies dynamics by making the voxel size adjustable and adaptable based on machining conditions. The system dynamically selects optimal voxel sizes according to different machining scenarios, workpiece geometries, and required precision levels, rather than using a fixed voxel size throughout the simulation process
Solution Approach 2:
The patent implements parameter changes by systematically varying voxel size as a key parameter to optimize the balance between display accuracy and computation time. The system evaluates different voxel size parameters and selects the most appropriate value based on the specific machining simulation requirements
2Productivity
If the size of the voxel is large, then the calculation time and drawing time are short, but the area of error is large and accuracy is low
Solution Approach 1:
The system dynamically adjusts voxel size based on real-time simulation requirements, allowing larger voxels in areas where high precision is not critical while maintaining smaller voxels in regions requiring higher accuracy, thus optimizing both productivity and precision
Solution Approach 2:
The patent utilizes parameter changes by establishing a relationship between voxel size and simulation requirements, enabling the system to select optimal voxel size parameters that achieve acceptable accuracy while minimizing computation and drawing time
3Measurement precision
If the number of voxels is large, then the display accuracy is high, but the amount of arithmetic processing is large
Solution Approach 1:
The patent applies parameter changes by optimizing the voxel size parameter to achieve the desired display accuracy while minimizing the total number of voxels and corresponding arithmetic processing requirements
