Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen or specific surface interaction is required to trigger functions, then the device can reliably execute operations, but the ease of operation is reduced and user convenience is limited
Solution Approach 1:
The patent replaces the mechanical touch screen interaction system with a motion sensor-based detection system. The motion sensor detects three-dimensional movement paths and rotation matrices of the indicating device, substituting direct surface contact with wireless motion recognition. This allows users to trigger functions by moving the indicating device in three-dimensional space without touching the screen, thereby improving ease of operation while maintaining reliable execution through precise motion tracking and computation of movement traces.
2Adaptability or versatility
If direct surface interaction is required, then the device can accurately recognize user input, but the adaptability to different interaction scenarios is limited
Solution Approach 1:
The patent transitions from two-dimensional touch screen interaction to three-dimensional motion recognition. The motion sensor captures movement in three-dimensional space, recording rotation matrices and calculating movement traces that incorporate spatial depth and directional information. This dimensional expansion enables the system to recognize diverse interaction patterns (locking, unlocking, volume adjustment, page switching) without sacrificing precision, as the three-dimensional movement data provides rich information for accurate input recognition.
3Adaptability or versatility
If motion sensors are used to detect three-dimensional movement, then the adaptability and ease of operation are improved, but the device complexity and energy consumption increase
Solution Approach 1:
The patent implements a universal motion recognition system that handles multiple functions through a single integrated approach. The motion sensor and control unit work together to detect various movement patterns (circling, diagonal movements, rotational gestures) and map them to different functions (locking, unlocking, volume control, page switching). This multi-functional design reduces the need for separate detection mechanisms for each function, thereby managing device complexity while maintaining high adaptability across different interaction scenarios.
