Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the cursor movement speed is increased by adjusting the host drive, then the cursor movement speed is improved, but the operation convenience deteriorates because other operations cannot be performed during adjustment
Solution Approach 1:
The patent implements dynamic adjustment of cursor movement speed by detecting pressure changes on the mouse body. The cursor speed is no longer fixed but dynamically changes based on real-time pressure detection, allowing users to adjust speed without interrupting other operations. This resolves the contradiction by making the speed adjustment dynamic and context-aware rather than requiring a static host drive configuration change.
Solution Approach 2:
The mouse device itself performs the speed adjustment function through its integrated pressure detection unit and microprocessor, eliminating the need for external host drive adjustments. The system serves itself by automatically calculating and applying speed multipliers based on detected pressure, allowing users to control cursor speed directly from the mouse without involving host system configurations.
2Speed
If the host drive is adjusted to change cursor movement speed, then the cursor movement speed is improved, but the adjustment time increases because other operations must be paused
Solution Approach 1:
The system performs preliminary action by continuously monitoring pressure on the mouse body and pre-calculating speed adjustments. When pressure is detected, the microprocessor immediately applies the appropriate speed multiplier without requiring any pause in user operations. This eliminates adjustment time by having the system ready to respond instantaneously rather than requiring interruptive configuration changes.
Solution Approach 2:
The cursor speed adjustment becomes a dynamic, real-time process rather than a static configuration change. The system continuously adapts cursor speed based on pressure input, allowing seamless adjustment during ongoing operations. This dynamic approach eliminates the time loss associated with pausing operations to change host drive settings.
3Adaptability or versatility
If a pressure detection unit is added to the mouse, then the cursor movement speed control flexibility is improved, but the device complexity increases
Solution Approach 1:
The pressure detection unit serves multiple functions: it detects pressure magnitude for speed control, determines direction of pressure application, and triggers different cursor speed multipliers based on pressure patterns. This multi-functionality justifies the added component by providing versatile speed control capabilities rather than requiring separate mechanisms for each function.
Solution Approach 2:
The system changes the operational parameter of cursor speed based on pressure detection input. By using pressure as a continuous variable to control speed multipliers, the system achieves flexible adaptability without complex mechanical adjustments. The microprocessor translates pressure parameters into speed adjustments, maintaining simplicity through software-based control rather than complex hardware mechanisms.
