Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a display touch panel is used to display images and writing information, then the electronic board can display visual content, but the structure becomes complicated and cost increases
Solution Approach 1:
The patent extracts the display function from the electronic board by removing the display touch panel, keeping only the essential writing board and sensor sheet components. This extraction eliminates the complex display structure while preserving the core handwriting detection functionality.
Solution Approach 2:
The patent employs a simple writing board surface that can be easily replaced or renewed, eliminating the need for expensive, complex display systems. The focus shifts to a cost-effective solution using basic materials like whiteboard surfaces or simple panels that serve the primary writing function without requiring sophisticated display technology.
2Ease of manufacture
If a display touch panel is used to display images and writing information, then the electronic board can display visual content, but the cost increases
Solution Approach 1:
The display function is extracted and removed from the system, eliminating the associated high costs. The patent accepts that visual information display capability is reduced or eliminated, focusing instead on preserving the essential handwriting detection and recognition functions at a lower cost.
Solution Approach 2:
The patent replaces expensive display touch panels with inexpensive, simple writing board materials that can be easily manufactured and replaced. This substitution dramatically reduces manufacturing costs while maintaining the core writing functionality, even though visual display capability is lost.
3Device complexity
If the writing board, sensor sheet, and chassis are integrated into an integral unit, then the structure is simplified, but the detection precision may be affected
Solution Approach 1:
The patent merges the writing board, sensor sheet, and chassis into a single integral unit, simplifying the overall structure and reducing the number of separate components. This integration maintains detection precision by ensuring close proximity and stable positioning between the sensor sheet and writing board, eliminating gaps or misalignments that could occur with separate components.
Solution Approach 2:
The integral unit serves multiple functions simultaneously: the writing board provides the writing surface, the sensor sheet detects pen contact positions, and the chassis provides structural support and housing. This multi-functionality approach simplifies the structure while maintaining or even improving detection precision through integrated design.
