Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple optical sensors are integrated to enable advanced input functions, then the functionality and versatility of the device is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple optical sensors (primary sensor and modifier sensors) into a unified input device that processes inputs from all sensors together. The processor receives inputs from multiple optical sensors and determines actions based on the combined input pattern, chronology, and direction, merging the functionality of several sensors into a single integrated device that provides comprehensive cursor control and gesture recognition.
Solution Approach 2:
The optical sensor device is designed to perform multiple functions through a single integrated system. The same set of optical sensors can detect different types of inputs (taps, clicks, gestures) and execute various actions (cursor movement, selection, scrolling, zooming, rotating) depending on the input pattern and chronology, making the device universal for different user interface requirements.
2Measurement precision
If inputs from multiple optical sensors are processed to provide comprehensive control, then the precision and intuitiveness of user input is improved, but the processing complexity increases
Solution Approach 1:
The processor continuously monitors the chronology and direction of inputs from multiple optical sensors and adjusts the determined action based on the sequence and pattern of inputs. This feedback mechanism allows the system to interpret complex input patterns (such as sequential taps or directional gestures) and translate them into precise cursor control actions, improving input detection accuracy through adaptive processing.
Solution Approach 2:
The system pre-establishes rules for determining actions based on input patterns, chronology, and direction. Before processing actual user input, the processor has predefined frameworks for interpreting different sensor combinations and sequences, which simplifies the real-time processing complexity while maintaining high precision in input detection.
