Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If handwriting input is displayed with original coordinates, then the input process is simple and fast, but the slope and spacing consistency is poor
Solution Approach 1:
The handwriting input is divided into multiple sections based on inflection points. Each section is processed independently to calculate representative slope values, allowing localized adjustment without affecting the entire handwriting input. This segmentation enables precise control over slope and spacing consistency in different regions of the handwriting.
Solution Approach 2:
The system changes the coordinate parameters of the handwriting input by adjusting horizontal coordinates based on calculated slope values. By modifying the x-coordinates of points while preserving vertical relationships, the system achieves consistent slope and spacing without altering the fundamental handwriting structure or requiring complex transformations.
2Manufacturing precision
If coordinate values are adjusted to improve handwriting appearance, then aesthetic quality is enhanced, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary identification of inflection points and calculation of representative slope values before final display. By pre-processing the handwriting data to determine key geometric features and slope characteristics, the system prepares adjustment parameters in advance, reducing real-time processing requirements and enabling faster display of aesthetically enhanced handwriting.
Solution Approach 2:
The system applies coordinate adjustment selectively to specific sections of handwriting that require improvement, rather than uniformly processing all points. By focusing computational effort on sections with significant slope or spacing variations, the system achieves aesthetic enhancement with reduced overall processing requirements.
