Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand-drawing graphics on electronic whiteboard, then user can create graphics freely, but drawing efficiency is low and accuracy is difficult to guarantee
Solution Approach 1:
The system copies the user's hand-drawn trajectory information and converts it into standard graphics through recognition algorithms. The hand-drawn graphic serves as a template or sketch, and the system generates the corresponding standard graphic (pie chart, bar chart, etc.) based on this trajectory, thereby maintaining drawing freedom while dramatically improving efficiency and accuracy.
Solution Approach 2:
The patent replaces the mechanical hand-drawing process with an automated recognition system. Instead of manually drawing each graphic element, users simply trace the desired shape, and the system automatically converts this trajectory into the corresponding standard graphic through image processing and pattern recognition algorithms.
2Ease of operation
If hand-drawing graphics on electronic whiteboard, then user can create graphics freely, but drawing accuracy is difficult to guarantee
Solution Approach 1:
The system copies the essential geometric features from the hand-drawn trajectory and reconstructs them as precise standard graphics. By recognizing the trajectory pattern (circle for pie chart, rectangle for bar chart, etc.) and converting it to vector-based standard graphic specifications, the system ensures high drawing accuracy while preserving user creativity.
Solution Approach 2:
The system changes the parameters of the hand-drawn graphic (trajectory points, shapes, proportions) into standardized graphic parameters. Through coordinate transformation and parameter normalization, the irregular hand-drawn trajectory is converted into precise mathematical definitions of standard graphics, thereby improving accuracy.
3Adaptability or versatility
If hand-drawing various graphics, then user can express ideas creatively, but subsequent processing becomes troublesome
Solution Approach 1:
The system copies the creative intent from hand-drawn graphics and transforms it into standardized graphic formats that are easy to process. The hand-drawn creative expression serves as input, and the system generates corresponding standard graphics (with proper formatting, labels, and structures) that can be easily copied, pasted, and processed in presentations or reports.
Solution Approach 2:
The patent introduces an intermediary processing layer between creative expression and final application. The hand-drawn graphic acts as a sketch or draft, and the system's recognition and generation mechanism serves as an intermediary that converts this sketch into a polished, ready-to-use standard graphic, thereby facilitating subsequent processing.
