Engineering Contradiction Analysis
1Adaptability or versatility
If additional conductive lines or light emitting elements are configured in the touch screen to implement three-dimensional gesture sensing, then three-dimensional gesture sensing function is achieved, but manufacturing cost and device complexity increase
Solution Approach 1:
The existing conductive lines in the touch screen are made to serve dual purposes: traditional two-dimensional touch sensing and three-dimensional gesture sensing. By dynamically assigning different conductive lines as transmitting or receiving lines based on detection needs, the system achieves three-dimensional sensing capability without adding new physical elements, thus maintaining structural simplicity while gaining enhanced functionality
Solution Approach 2:
The system dynamically adjusts the roles of conductive lines (transmitting or receiving) and the sensing area configuration based on real-time detection requirements. This dynamic reconfiguration allows the same physical structure to adapt to different sensing modes, eliminating the need for fixed additional elements and reducing overall device complexity

3Measurement precision
If traditional three-dimensional gesture sensing method is used, then implementation is achieved, but sensing region is limited and detection accuracy is lower compared to two-dimensional touch sensing
Solution Approach 1:
The system dynamically adjusts the sensing area configuration by selectively activating different conductive lines as transmitting or receiving lines based on the detected conductor position. This dynamic expansion allows the sensing region to grow beyond fixed boundaries, improving both the coverage area and detection accuracy simultaneously
Solution Approach 2:
The system transitions from traditional two-dimensional touch sensing to three-dimensional gesture sensing by utilizing the vertical dimension (distance from screen surface) through capacitive coupling. By detecting capacitance changes in the third dimension and using dynamic line configuration, the system expands sensing capability into three-dimensional space while maintaining and enhancing detection accuracy
