Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If capacitance variations are used to determine object proximity, then hovering touch detection is enabled, but the operation lacks intuitive control and flexibility
Solution Approach 1:
The patent applies parameter changes by transitioning from detecting only capacitance variations to detecting multiple parameters including distance and angle of the touch object. This enables more intuitive control as users can naturally vary distance and angle when interacting with the screen, while also providing greater functional control flexibility by mapping different distance and angle ranges to different operations.
2Adaptability or versatility
If only capacitance detection is used, then the sensing mechanism is simple, but distance and angle information cannot be utilized for functional control
Solution Approach 1:
The patent implements multi-functionality by enabling the touch screen to perform multiple detection functions using the same hardware infrastructure. The touch screen continues to detect capacitance while also detecting distance and angle information, allowing a single device to provide comprehensive hovering control with multiple operational modes without requiring separate sensing systems.
3Ease of operation
If distance and angle detection are added, then intuitive hovering control is achieved, but the detection system becomes more complex
Solution Approach 1:
The patent merges multiple detection functions into a unified hovering control system. By combining capacitance detection, distance detection, and angle detection into a single integrated system, the patent achieves intuitive hovering operation where users can naturally control objects by varying their finger's distance and angle from the screen, while the system processes all parameters together to determine the appropriate function.
