Solution Overview
Problem
Conventional input devices, such as mice and touchpads, require frequent switching between modes, which is inconvenient for users due to differences in hand gestures and operating scenarios, and lack seamless integration of functions.
Innovation Solution
An input device with a state detecting module comprising first and second state detecting units, and a control unit that switches between mouse, touchpad, and remote control modes based on detected usage states, allowing for continuous user behavior without mode changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mouse and touchpad are used as separate input devices, then each device can be optimized for its specific function, but users have to switch between modes frequently which reduces ease of operation
Solution Approach 1:
The patent combines mouse and touchpad functions into a single integrated input device. The device includes a touch-sensitive surface that can operate in multiple modes (mouse mode, touchpad mode, remote control mode) depending on detected usage patterns. This merging eliminates the need for separate devices and frequent mode switching while maintaining the functional advantages of each mode.
Solution Approach 2:
The patent implements dynamic mode switching based on detected usage states. The control unit automatically transitions between input modes (mouse, touchpad, remote control) according to signals from state detecting units that monitor hand gestures, device orientation, and interaction patterns. This dynamic adaptation allows the device to optimize its function in real-time without requiring manual mode changes from the user.
2Ease of operation
If mouse and touchpad are integrated into a single device, then mode switching is eliminated, but the device complexity increases
Solution Approach 1:
The patent creates a universal input device that performs multiple functions (mouse control, touchpad gestures, remote control operations) through a single touch-sensitive surface. The control unit intelligently routes different input types to appropriate processing modes based on detected usage patterns, allowing one physical structure to serve multiple purposes without requiring separate dedicated hardware for each function.
Solution Approach 2:
The device incorporates state detecting units that automatically monitor usage patterns and trigger appropriate mode transitions without user intervention. The system self-adjusts its operational mode based on detected hand gestures, device orientation, and interaction patterns, eliminating the need for manual mode switching while managing the complexity of multiple functions through automated decision-making.
3Adaptability or versatility
If different input modes are integrated, then versatility is improved, but the difficulty of detecting and measuring usage state increases
Solution Approach 1:
The patent divides the detection function into multiple specialized state detecting units positioned at different locations on the device. Each detecting unit monitors specific aspects of usage (hand presence, grip position, device orientation) and generates separate signals. The control unit integrates these segmented detection signals to determine the overall usage state and select the appropriate input mode, making the complex detection task more manageable through functional decomposition.
