Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of setting forming conditions for three-dimensional objects increases as the shape of the object becomes more complex, making it difficult to calculate optimal physical property values and corresponding forming conditions for each element.
Innovation Solution
A three-dimensional object data generation apparatus that divides the object into sub-objects based on physical property value thresholds, calculates representative values for each sub-object, and sets forming conditions using predetermined correspondences to simplify the process of generating three-dimensional object data.

Engineering Contradiction Analysis
1Manufacturing precision
If physical properties of three-dimensional objects are analyzed to calculate optimal physical property values and forming conditions for each element, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The three-dimensional object is divided into multiple sub-objects based on physical property value thresholds. This segmentation allows the complex analysis process to be applied to smaller, more manageable portions of the object, reducing overall process complexity while maintaining manufacturing precision for each element.
Solution Approach 2:
Different forming conditions are calculated and applied to different sub-objects based on their specific physical property values. This local quality approach ensures that each region of the three-dimensional object receives optimized forming conditions tailored to its characteristics, improving manufacturing precision without requiring a single overly complex global process.
2Manufacturing precision
If the object is divided into more elements for detailed analysis, then manufacturing precision is improved, but the complexity of setting forming conditions increases
Solution Approach 1:
By segmenting the object into sub-objects based on physical property thresholds, the patent manages element-level detail through hierarchical grouping. This reduces the complexity of managing forming conditions by organizing numerous elements into fewer manageable sub-objects while preserving the ability to control each element's properties.
Solution Approach 2:
The patent uses physical property value thresholds as parameters to automatically group elements into sub-objects. This parameter-based approach simplifies forming condition management by transforming the complexity of individual element control into a more manageable threshold-based classification system, where elements with similar properties are grouped together.
