Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-screen laptops with fixed touchpads become inconvenient as user attitudes and holding states vary, limiting applicability and causing operational inefficiencies.
Innovation Solution
A touch control method that obtains attitude and holding information to dynamically determine a variable target area on dual screens, generating touch parameters for accurate and efficient touch operations based on the size and position of the target area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the touchpad is fixed at a fixed position with unchanged size, then the device structure is simple and easy to manufacture, but the applicability and convenience are reduced when users hold the device in different attitudes
Solution Approach 1:
The touchpad area is transformed from a fixed static region to a dynamic adjustable region. The system dynamically determines the touchpad area based on detected holding attitudes, allowing the touchpad position and size to change according to different usage scenarios. This resolves the contradiction by making the touchpad adaptive to various holding attitudes while maintaining a relatively simple overall device structure.
Solution Approach 2:
The system changes the parameters (position and size) of the touchpad area based on different holding attitudes. By detecting the holding attitude and adjusting the touchpad area parameters accordingly, the system achieves adaptability without requiring multiple physical touchpads or complex mechanical structures.
2Ease of operation
If the touchpad is fixed at a fixed position with unchanged size, then the device structure is simple, but the convenience and operational efficiency are reduced when users hold the device in different attitudes
Solution Approach 1:
The touchpad area is transformed from a fixed static region to a dynamic adjustable region. The system dynamically determines the touchpad area based on detected holding attitudes, allowing the touchpad position and size to change according to different usage scenarios. This resolves the contradiction by making the touchpad adaptive to various holding attitudes while maintaining a relatively simple overall device structure.
Solution Approach 2:
The system automatically detects the holding attitude and adjusts the touchpad area without requiring manual user configuration. This self-adjusting mechanism improves convenience by eliminating the need for users to manually reconfigure the touchpad for different attitudes, while the automated nature keeps the system relatively simple.
3Adaptability or versatility
If the touchpad area is dynamically adjusted based on holding attitudes, then the applicability and convenience are improved, but the complexity of determining and controlling the touchpad area increases
Solution Approach 1:
The system pre-establishes the relationship between different holding attitudes and corresponding touchpad areas. By detecting the holding attitude and mapping it to a predetermined touchpad configuration, the system achieves dynamic adaptability without requiring complex real-time calculation and control algorithms, thus reducing control complexity.
