Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional touch screen interface is used, then device simplicity is maintained, but control precision and interaction capability for 3D objects is insufficient
Solution Approach 1:
The touch controller is segmented into multiple independent sensor arrays arranged in a grid pattern, with each sensor detecting touch events independently. This segmentation enables precise localization of touch events in three-dimensional space while maintaining a relatively simple overall device structure.
Solution Approach 2:
The patent transitions from traditional two-dimensional touch detection to three-dimensional touch detection by adding a vertical dimension with multiple sensor layers or stacked sensor arrays. This dimensional expansion enables precise control of 3D virtual objects while the underlying sensor technology remains based on conventional touch screen principles.
2Adaptability or versatility
If multiple sensor arrays are implemented, then control capability is enhanced, but manufacturing complexity increases
Solution Approach 1:
Multiple sensor arrays are merged into a single integrated touch controller unit with unified processing logic. The sensor arrays share common circuitry and control mechanisms, reducing manufacturing steps and assembly complexity while maintaining enhanced control capability through the combined sensor network.
Solution Approach 2:
The sensor arrays are designed with universal functionality to detect various types of touch events (single touch, multi-touch, pressure, gesture) using the same hardware infrastructure. This multi-functionality reduces the need for specialized components for different control scenarios, simplifying manufacturing while enhancing control versatility.
3Ease of operation
If 3D touch control is added, then user interaction quality is improved, but device cost increases
Solution Approach 1:
The touch sensor arrays utilize the device's existing processing unit and memory to handle touch event detection and processing. By leveraging existing computational resources rather than adding dedicated processing hardware, the system achieves enhanced 3D touch control capability while minimizing additional device cost.
