Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simple touch operations (click, double click, drag and drop) are used for control, then the device structure remains simple, but the device cannot meet diverse operation requirements and complex manipulation needs
Solution Approach 1:
The patent changes the parameter of touch interaction from simple contact detection to pressure value detection. By detecting pressure values and their changes over time, the system can distinguish between different user intentions (e.g., zoom in vs. zoom out based on pressure increase/decrease), thereby enhancing operational versatility without adding physical controls
Solution Approach 2:
The existing touch screen is made multi-functional by interpreting pressure variations. The same hardware surface can now perform simple clicks, zoom operations, rotation, and other complex manipulations based on pressure patterns, making one component serve multiple functions
2Ease of operation
If existing touch operations are used for complex manipulations (zoom in/out, rotation, flipping), then the device structure remains simple, but the manipulation is not consistent with real object handling practices
Solution Approach 1:
The patent copies real-world manipulation physics into the digital interface. By detecting pressure increases to simulate picking up an object and pressure decreases to simulate putting it down, the system recreates natural handling gestures, making the interaction intuitive and consistent with physical object manipulation
3Adaptability or versatility
If more functions are provided to meet diverse user needs, then the adaptability increases, but the operation complexity and difficulty of manipulation increase
Solution Approach 1:
The pressure-sensitive touch surface serves as a universal control interface for all operations. Whether for zooming, rotating, or other manipulations, the same pressure-based interaction paradigm is used, reducing the need to learn different control schemes for different functions
