Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital image editing systems face challenges in accurately arranging and creating additional objects that complement complex shapes, leading to visual artifacts and inaccuracies due to the inability to manually recreate complex shapes in a user interface.
Innovation Solution
Implementing curve offset operations that align input points based on a curve in a digital image at an offset, allowing for flexible deviations to generate paths that follow or depart from the curve, thereby improving accuracy and reducing visual artifacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional manual methods are used to recreate complex shapes in a user interface, then user control and flexibility are maintained, but accuracy and precision deteriorate leading to visual artifacts
Solution Approach 1:
The patent introduces curve offset operations as an intermediary mechanism between the user and complex shape creation. Instead of manually recreating complex shapes point-by-point, users define simple control points that automatically generate accurate complex curves through offset operations, eliminating visual artifacts while maintaining user control.
Solution Approach 2:
The patent employs copying by generating new paths that replicate the geometric properties of existing curves at specified offsets. This allows accurate reproduction of complex shapes by copying their mathematical definitions rather than manually redrawing them, ensuring precision without manual effort.
2Manufacturing precision
If manual recreation of complex shapes is attempted, then flexibility in shape modification is maintained, but manufacturing precision deteriorates due to inability to accurately replicate complex geometries
Solution Approach 1:
The patent segments complex shape creation into manageable components by allowing users to define only critical control points rather than every point on the curve. The system then automatically generates the complete complex geometry from these segmented inputs, achieving high precision without requiring complex manual operations.
Solution Approach 2:
The patent utilizes parameter changes by allowing users to modify simple geometric parameters (control point positions, offset distances) that automatically transform into complex shape variations. This approach maintains manufacturing precision through mathematical consistency while reducing operational complexity to simple parameter adjustments.
3Measurement precision
If automated curve offset operations are implemented, then accuracy and visual quality improve, but system complexity increases
Solution Approach 1:
The patent implements self-service by enabling the system to automatically perform complex curve offset calculations and path generation based on simple user inputs. The automated operations handle the mathematical complexity internally, providing high-precision results without requiring the user to understand or manage the underlying system complexity.

AI summary
Curve offset operations as implemented by a digital image editing system are described. Input points are received via a user interface and a determination is made that a first set of the input points satisfy a condition for use as part of a curve offset operation with respect to a curve. A first segment is added to a path using the curve offset operation. The first segment is generated by aligning the first set of input points using an offset value based on the curve. A determination is then made that a second set of the input points do not satisfy the condition for use as part of the curve offset operation and a second segment is added to the first segment of the path. The second segment is generated using the second set of points and the path is displayed.
