Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embroidery data creation apparatuses have limited ability to express natural stitches as line segments with similar angles are not always adjacent to each other, resulting in a restricted embroidery pattern effect.
Innovation Solution
An apparatus and method that includes a processor and memory to arrange line segments based on image data, connecting them sequentially by prioritizing combinations of distance, angle difference, and angle ranges to form natural stitches, ensuring that line segments with similar characteristics are connected naturally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If line segments are connected based only on distance and angle difference thresholds, then the connection process is simple, but the embroidery pattern cannot be expressed naturally when line segments with similar angles are not adjacent
Solution Approach 1:
The patent changes the connection criteria from simple distance and angle difference thresholds to a comprehensive priority system that evaluates multiple parameters (distance, angle difference, and angle range) simultaneously. This allows the system to select the most appropriate next line segment based on combined parameter assessment, enabling natural embroidery pattern expression even when similar-angle segments are not adjacent.
Solution Approach 2:
The patent pre-calculates and stores priority information for each line segment connection based on distance, angle difference, and angle range combinations. This preliminary action allows the connection process to quickly retrieve and compare pre-computed priorities rather than performing complex calculations during real-time connection, thus improving pattern quality without proportionally increasing processing complexity.
2Manufacturing precision
If multiple parameters (distance, angle difference, angle range) are considered for line segment connection, then the embroidery pattern is expressed more naturally, but the calculation and decision-making process becomes more complex
Solution Approach 1:
The patent segments the evaluation process into distinct components: distance evaluation, angle difference evaluation, and angle range evaluation. Each parameter is assessed independently and then integrated through a priority system. This segmentation makes the complex multi-parameter evaluation more manageable by breaking it into smaller, independent assessment steps that can be processed systematically.
Solution Approach 2:
The patent performs preliminary calculations to determine priority values for different parameter combinations before the actual connection process. By pre-computing the priority information for various distance, angle difference, and angle range combinations, the system reduces the real-time computational burden during line segment connection while maintaining comprehensive parameter evaluation.
3Manufacturing precision
If line segments are connected with strict angle and distance criteria, then stitch naturalness is improved, but the number of jump stitches increases and work efficiency deteriorates
Solution Approach 1:
The patent implements a dynamic priority-based selection system that adapts to different line segment configurations. Instead of applying fixed strict criteria, the system dynamically evaluates multiple candidate line segments using priority information derived from distance, angle difference, and angle range. This dynamic approach allows the system to maintain stitch naturalness by selecting the best available candidate while avoiding excessive jump stitches through flexible, context-aware decision-making.
Solution Approach 2:
The patent changes from binary threshold-based connection criteria to a multi-level priority system that considers combinations of distance, angle difference, and angle range parameters. This parameter transformation allows for more nuanced connection decisions that can achieve natural stitch appearance without unnecessarily increasing jump stitches, thereby maintaining work efficiency.
