Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a computer mouse includes fixed resistance keys, then the device structure is simple, but the device lacks adaptability and cannot reduce user fatigue
Solution Approach 1:
The patent implements dynamic resistance adjustment by replacing fixed mechanical springs with controllable resistance devices (electromagnetic actuators or voice coil motors) that can vary their resistance force in real-time based on user preferences and operational context, allowing the same physical structure to adapt to different user needs
Solution Approach 2:
The patent changes the resistance force parameter dynamically through electronic control systems that adjust current to electromagnetic actuators, enabling continuous variation of resistance levels without mechanical reconfiguration, thus achieving adaptability while maintaining structural simplicity
2Adaptability or versatility
If a computer mouse includes force sensors and control circuits, then the device provides customizable resistance profiles, but the device complexity increases
Solution Approach 1:
The patent employs a multi-functional control circuit that simultaneously performs force sensing, resistance adjustment, user input processing, and communication functions, consolidating multiple control tasks into a single integrated system rather than separate dedicated circuits for each function
Solution Approach 2:
The patent implements feedback control where force sensors detect user applied force and the control circuit automatically adjusts resistance device output to maintain desired force profiles, creating a closed-loop system that reduces the need for complex open-loop control mechanisms
3Measurement precision
If the resistance force is increased to provide tactile feedback, then the control precision is improved, but the user effort and fatigue increase
Solution Approach 1:
The patent employs periodic or pulsed resistance forces rather than continuous high resistance, providing tactile feedback only at critical moments (key press detection, threshold crossing) while maintaining low resistance during normal operation, thus achieving precision feedback without sustained user effort
Solution Approach 2:
The patent dynamically adjusts resistance force levels based on operational context, providing high resistance only when tactile feedback is needed for precision control, and reducing resistance to minimal levels during normal use, optimizing the balance between feedback quality and user fatigue
