Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for simulating Chinese brush pen writing on intelligent terminals require a large number of sampling points, leading to high computational resources usage and low processing efficiency, and often fail to accurately represent the smoothness and aesthetics of traditional Chinese brush pen strokes due to the lack of connection modeling between writing skills.
Innovation Solution
A handwriting forming method that determines trajectory points on a touch device, establishes raindrop-shaped trajectory units, and calculates connection points based on connection modes to fill polygons, thereby creating smooth and aesthetically pleasing Chinese brush pen-like handwriting with reduced computational requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a large number of sampling points are used to simulate Chinese brush pen writing, then the smoothness and aesthetics of the handwriting can be improved, but the computational resource usage increases and processing efficiency decreases
Solution Approach 1:
The patent divides the continuous writing trajectory into discrete trajectory units, each representing a segment of the brush stroke. By segmenting the writing path into manageable units with defined connection modes, the system can process handwriting with fewer sampling points while maintaining smoothness and aesthetic quality, thus resolving the contradiction between precision and processing efficiency.
Solution Approach 2:
The patent introduces parameter-based control for trajectory unit generation and connection mode selection. By adjusting parameters such as sampling interval, trajectory unit size, and connection mode coefficients, the system can optimize the balance between handwriting quality and computational efficiency, allowing high-quality output with reduced sampling requirements.
2Manufacturing precision
If a large number of sampling points are used to simulate Chinese brush pen writing, then the smoothness and aesthetics of the handwriting can be improved, but the computational resource usage increases
Solution Approach 1:
The patent segments the writing trajectory into trajectory units that can be processed independently. This segmentation reduces the overall computational burden by breaking down the complex task of rendering continuous brush strokes into smaller, more efficient units, thereby reducing energy consumption while maintaining visual quality.
Solution Approach 2:
The patent applies partial sampling strategies where not all trajectory points require full processing. By selectively processing only critical trajectory units and using simplified connection modes for certain segments, the system achieves acceptable handwriting quality with reduced computational resource usage.
3Device complexity
If connection modeling between writing skills is not implemented, then the computational complexity can be reduced, but the accuracy in representing traditional Chinese brush pen strokes deteriorates
Solution Approach 1:
The patent implements local quality by applying different connection modes to different trajectory units based on their specific characteristics. Instead of using a uniform complex model throughout, the system selects appropriate connection modes (e.g., linear, quadratic, cubic) for different segments, reducing overall computational complexity while maintaining accuracy where it matters most.
Solution Approach 2:
The patent uses parameter-based control to switch between different connection modes and modeling approaches. By changing parameters such as the connection mode type and trajectory unit properties based on local trajectory characteristics, the system achieves accurate brush stroke representation with controlled computational complexity.
