Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the touchpad size is increased to provide larger operable region for users, then the user's finger operation area is enlarged, but the touchpad occupies more space on the notebook computer
Solution Approach 1:
The touchpad is divided into multiple predetermined regions (first predetermined region, second predetermined region, third predetermined region) with different functions. This segmentation allows each region to serve specific purposes: basic touch operations in the first region, radial controller simulation in the second region, and stylus mapping adjustment in the third region, thereby maximizing the utility of the available space without requiring a larger overall touchpad area.
Solution Approach 2:
The touchpad is designed to perform multiple functions beyond basic touch detection. By implementing radial controller simulation and stylus mapping adjustment capabilities within the same touchpad structure, the device achieves multi-functionality that resolves the space occupation issue while providing diverse operational capabilities.
2Device complexity
If the touchpad is used only for general touch detection, then the device structure remains simple, but the large-sized touchpad space is wasted and functionality is limited
Solution Approach 1:
The touchpad is enhanced to perform multiple functions including basic touch detection, radial controller simulation through displacement detection in the second predetermined region, and stylus mapping region adjustment through touch operations in the third predetermined region. This multi-functionality approach increases adaptability without requiring additional hardware components.
Solution Approach 2:
The system utilizes changes in touch parameters (position, displacement, time interval) to differentiate between various operation types. By analyzing displacement in the first preset time interval and determining whether touch operations occur in predetermined regions, the system enables diverse functions while maintaining a simple touchpad structure.
3Adaptability or versatility
If additional hardware is added to enhance touchpad functionality, then the operation diversity is improved, but the device complexity and space occupation increase
Solution Approach 1:
The existing touchpad hardware is made multi-functional through software processing. The same touchpad structure supports basic touch operations, radial controller simulation, and stylus mapping adjustment by analyzing touch signals differently based on the predetermined region where the touch occurs, eliminating the need for additional hardware.
Solution Approach 2:
The patent simulates the functionality of a radial controller through software interpretation of touchpad displacement signals, rather than requiring a physical radial controller hardware component. This copying approach allows radial controller operations to be performed using only the existing touchpad structure.
Data Source
AI summary
In the touch operation method, a touch signal is generated in response to a touch operation performed on the touchpad, whether the touch operation is located in at least one predetermined region of the touchpad is determined according to the touch signal, and when the touch operation is located in the predetermined region, whether there is a displacement of the touch operation in a preset time interval is determined according to the touch signal. When it is determined that there is a displacement of the touch operation in the preset time interval, an operation signal corresponding to a predetermined function of the electronic device is generated according to the displacement of the touch operation, to perform the predetermined function.
