Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual hand-drawing is used to create graphics on electronic whiteboard, then user can freely draw any shape, but drawing efficiency is low and accuracy is difficult to guarantee
Solution Approach 1:
The system automatically recognizes the hand-drawn trajectory and converts it into a standard graphic without requiring manual intervention for each drawing action. The graphic recognition unit processes the trajectory information and automatically generates the corresponding standard graphic, making the system serve itself rather than requiring continuous manual input for graphic creation.
Solution Approach 2:
The patent replaces the manual mechanical drawing process with an automated recognition system. Instead of manually creating each graphic element, users simply draw the basic trajectory, and the system's graphic recognition unit processes this trajectory information to automatically generate the complete standard graphic, substituting manual mechanical operations with automated digital processing.
2Manufacturing precision
If manual hand-drawing is used to create graphics, then user can control the graphic shape, but graphic accuracy and standardization are poor
Solution Approach 1:
The patent introduces trajectory information as an intermediary between the user's hand-drawing action and the final standard graphic. The graphic recognition unit processes the trajectory information as an intermediate representation and converts it into the standard graphic format. This intermediary trajectory information simplifies the system by allowing users to draw freely while maintaining accuracy through automated processing.
Solution Approach 2:
The system changes the parameters of the graphic representation from free-form hand-drawn trajectories to standardized graphic parameters. The graphic recognition unit transforms the trajectory information into standardized graphic elements with precise geometric parameters, ensuring accuracy and standardization while maintaining ease of use through automated parameter transformation.
3Productivity
If standard graphics are used instead of hand-drawn graphics, then graphic accuracy and efficiency are improved, but user flexibility in creating custom graphics is reduced
Solution Approach 1:
The system provides dynamic adaptability by allowing users to draw freely with their hand while the system automatically adapts the trajectory into appropriate standard graphics. The graphic recognition unit dynamically processes different trajectory patterns and converts them into suitable standard graphic types, maintaining both efficiency and user creativity flexibility through adaptive automated processing.
