Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high precision position sensor and button press logic are used, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The patent implements dynamic switching between high precision and low precision modes based on usage context. The system monitors activity levels and automatically adjusts position sensor precision and button press logic accordingly, using high precision only when needed for tasks like gaming while consuming low precision mode during normal operations to save power.
Solution Approach 2:
The system changes operational parameters (precision levels) based on detected usage patterns. It monitors mouse movement characteristics, button press frequency, and application context to dynamically adjust sensor sampling rates and processing intensity, thereby optimizing the balance between measurement precision and power consumption.
2Measurement precision
If high precision position sensor is used, then measurement precision is improved, but duration of action decreases
Solution Approach 1:
The system dynamically adjusts position sensor precision based on usage context to extend battery life. During low-activity periods and normal computing tasks, it operates in low precision mode with reduced power consumption. During high-activity periods or gaming sessions, it switches to high precision mode, thereby optimizing the balance between measurement quality and battery duration.
Solution Approach 2:
The system implements periodic monitoring of usage patterns and application contexts to determine when to switch between precision modes. It uses activity detection algorithms that periodically assess mouse usage intensity and automatically adjust sensor operation accordingly, ensuring high precision is available when needed while conserving battery during extended low-precision periods.
3Use of energy by moving object
If mouse precision is adjusted manually, then power consumption is reduced, but ease of operation deteriorates
Solution Approach 1:
The system performs self-service by automatically detecting usage patterns and application contexts to determine the appropriate precision level. It monitors mouse movement characteristics, button press frequency, and running applications to autonomously switch between high and low precision modes without requiring user intervention, thereby maintaining ease of operation while optimizing power consumption.
Solution Approach 2:
The system uses feedback from usage pattern analysis to automatically adjust precision settings. It continuously monitors mouse activity metrics and application context, then uses this feedback to dynamically switch between precision modes, eliminating the need for manual user adjustment while adapting to actual usage needs in real-time.
4Measurement precision
If position sensor resolution is increased, then measurement precision is improved, but adaptability to different display resolutions deteriorates
Solution Approach 1:
The system dynamically adjusts position sensor resolution based on the detected display resolution. When a high-resolution display is detected, it increases position sensor resolution to maintain cursor movement consistency. When a lower-resolution display is detected, it reduces position sensor resolution accordingly, thereby adapting to different display configurations while maintaining optimal performance.
Solution Approach 2:
The system changes position sensor resolution parameters based on display characteristics. It detects the connected display's resolution and automatically adjusts the mouse's position sensor sampling rate and reporting interval to match, ensuring consistent cursor behavior across different display resolutions without manual configuration.

AI summary
An information handling system mouse includes a position sensor that detects movement and a push button that detects button press inputs for communication to an information handling system. The position sensor detects positions with a high sensitivity having a higher power consumption or a low sensitivity having a lower sensitivity. The push button detects button press inputs with a high scan rate having a higher power consumption or a low scan rate having a lower power consumption. The mouse configures to plural high and low power consumption modes based upon a detected usage pattern and/or a command from an information handling system, such as to adapt the mouse to use by different applications executing on the information handling system.
