Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing editing devices for three-dimensional shape data lack an efficient method for setting a three-dimensional initial edit range in the depth direction of a two-dimensional region, requiring users to manually specify lengths, which can be cumbersome and complex.
Innovation Solution
An editing device that includes a two-dimensional region setter and an initial edit range setter, allowing users to set a three-dimensional initial edit range based on the dimensions of the two-dimensional region, with options to automatically determine the depth length or allow user-defined settings, enabling easy modification of the edit range without manual specification of depth length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually specify the depth length for setting a three-dimensional initial edit range, then the edit range can be precisely controlled, but the operation becomes cumbersome and complex
Solution Approach 1:
The system automatically calculates and sets the depth length based on the two-dimensional region dimensions, allowing the system to serve itself rather than requiring manual user input. The initial edit range setter automatically determines the three-dimensional edit range parameters from the two-dimensional region, eliminating the need for users to manually specify depth length while maintaining precise control.
Solution Approach 2:
The system changes the parameter input method from manual specification to automatic derivation. Instead of requiring users to input depth length as a separate parameter, the system derives this parameter automatically from the two-dimensional region's width and height, transforming the operation from complex manual parameter entry to simple region selection.
2Reliability
If users manually specify the depth length for three-dimensional initial edit range, then control over the edit range is maintained, but the editing process becomes time-consuming
Solution Approach 1:
The system performs preliminary calculation of the depth length and initial edit range parameters before the user actually needs to perform editing operations. By pre-calculating the three-dimensional edit range based on the two-dimensional region selection, the system eliminates the time-consuming manual specification step while maintaining reliable control over the edit range.
Solution Approach 2:
The initial edit range setter automatically performs the time-consuming task of calculating depth length and defining the three-dimensional edit range, freeing the user from manual specification while maintaining control. The system serves itself by automatically deriving all necessary parameters from the two-dimensional region selection.
3Ease of operation
If automatic depth length determination is implemented, then operation simplicity is improved, but the system complexity increases
Solution Approach 1:
The initial edit range setter performs multiple functions: it receives the two-dimensional region, calculates the depth length based on region dimensions, determines the three-dimensional initial edit range, and prepares it for editing operations. By consolidating these multiple functions into a single automated component, the system achieves operational simplicity without proportionally increasing overall system complexity.

AI summary
An editing device for three-dimensional shape data includes: a two-dimensional region setter that sets a two-dimensional region on a two-dimensional plane, on which a three-dimensional shape represented by three-dimensional shape data is projected; and an initial edit range setter that sets a three-dimensional initial edit range in a depth direction of the two-dimensional region set by the two-dimensional region setter.
