Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional editing methods are used for three-dimensional shape data, then the editing process is simple, but the precision and flexibility in assigning attributes to specific ranges is insufficient
Solution Approach 1:
The patent segments the three-dimensional shape data into multiple ranges based on distribution patterns, allowing independent attribute assignment to each range. The editing device divides the shape data into first, second, and third ranges with different material distributions, enabling precise control over specific regions without affecting the entire model.
Solution Approach 2:
The patent implements local quality by allowing different attribute assignments to different ranges within the three-dimensional shape data. Each range can have distinct material properties, colors, or other attributes assigned based on its specific distribution pattern, rather than applying uniform attributes to the entire shape.
2Adaptability or versatility
If uniform attribute assignment is used throughout the three-dimensional shape, then the process is efficient, but the flexibility to represent complex shapes and material distributions is limited
Solution Approach 1:
The patent introduces dynamic attribute assignment through distribution patterns that can be adjusted and modified. Users can change material distributions, assign different attributes to different ranges, and reconfigure the shape data dynamically without starting from scratch, balancing flexibility with editing efficiency.
Solution Approach 2:
The patent utilizes parameter changes by allowing users to modify distribution pattern parameters such as material types, concentration gradients, and spatial distributions. These parameter adjustments enable versatile representation of complex shapes while maintaining an efficient editing workflow through systematic control.
3Manufacturing precision
If detailed range-by-range attribute assignment is implemented, then the representation of complex shapes improves, but the time and complexity of the editing process increases
Solution Approach 1:
The patent applies preliminary action by automatically generating distribution patterns and initial range divisions before detailed attribute assignment. The system pre-processes the three-dimensional shape data to identify suitable ranges and apply default distribution patterns, reducing the time required for manual detailed editing while maintaining precision.
Solution Approach 2:
The patent utilizes copying by allowing users to replicate distribution patterns and attribute assignments across multiple ranges. Once a distribution pattern is defined for one range, it can be copied and adapted to other ranges, significantly reducing the time required for detailed attribute assignment while maintaining consistency and precision.

AI summary
An editing device for three-dimensional shape data includes: a first setting part that sets at least one first characteristic point on three-dimensional shape data forming a three-dimensional shape; a second setting part that sets at least one second characteristic point on a predetermined distribution pattern, the at least one second characteristic point corresponding to the at least one first characteristic point set by the first setting part; and an assigning part that assigns an attribute to a three-dimensional range included in at least part of the three-dimensional shape in accordance with the distribution pattern so that the at least one first characteristic point set by the first setting part and the at least one second characteristic point set by the second setting part correspond to each other.
