Anchor Point Hierarchy for Flex Circuit Bend Ordering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic design automation (EDA) products face challenges in defining and managing bend ordering for multiple bends in a given flex area, making it cumbersome for users to provide accurate bending operations in 3D designs supported by a 2D database.
Innovation Solution
A computer-implemented method that uses an anchor point to establish a hierarchy for bend operations, allowing for automatic determination of bend ordering and fan-out of shapes along intersecting lines, thereby simplifying the management of bend orders and ensuring accurate bending transformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually define and manage bend ordering for multiple bends in a flex area, then bending operations can be controlled, but the process becomes cumbersome and complex
Solution Approach 1:
The system automatically determines bend ordering by analyzing the hierarchical relationship between shapes and bend lines, eliminating the need for users to manually define and manage bend sequences. The computer automatically performs the task that would otherwise require user intervention, making the system self-sufficient in determining the correct bending order based on shape hierarchy and spatial relationships
Solution Approach 2:
The system pre-establishes a hierarchical structure of shapes with parent-child relationships before bend operations are executed. This preliminary organization of shapes into a tree structure with root parents and children allows the system to automatically determine bend ordering based on the hierarchy, preparing the data structure in advance so that bend sequences can be derived without user intervention
2Ease of manufacture
If existing EDA products only define bend lines without bend ordering, then the system is simpler to implement, but it cannot provide accurate cumulative bending effects
Solution Approach 1:
The system segments the set of bend lines into ordered sequences by establishing a hierarchical structure where bend lines are associated with parent-child shape relationships. Each bend line is assigned a position in the sequence based on its relationship to the anchor point and other bend lines, dividing the undifferentiated set of bends into a structured, ordered sequence that enables accurate cumulative transformation
Solution Approach 2:
The system changes the parameter of bend lines by assigning hierarchical attributes (parent-child relationships, depth levels, fan-out identifiers) to each bend line based on its spatial relationship to the anchor point and other shapes. These parameter changes transform simple geometric bend lines into structured elements with inherent ordering information, enabling accurate determination of bend sequences without user input
