Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the position detection area range is manually set to match the display area aspect ratio, then the aspect ratio difference is reduced, but the user effort and time required increases
Solution Approach 1:
The system automatically adjusts the position detection area range without requiring user intervention. The electronic device autonomously calculates the appropriate range based on the display area's aspect ratio and transmits this information to the position detection device, which then configures its detection area accordingly. This self-service mechanism eliminates the need for manual setting while achieving precise aspect ratio matching.
Solution Approach 2:
The electronic device preliminarily calculates and determines the optimal position detection area range before the user actually uses the pen tablet. By pre-configuring the aspect ratio settings based on the display area characteristics, the system prepares everything in advance, so when the user connects the devices, the correct settings are already in place without requiring any manual adjustment.
2Manufacturing precision
If the position detection area range is manually adjusted, then the aspect ratio difference is reduced, but the operation complexity increases
Solution Approach 1:
The system performs automatic configuration of the position detection area range without requiring user knowledge or intervention. The electronic device autonomously determines the optimal settings based on the display area's aspect ratio and communicates this information to the position detection device, completely eliminating the complexity of manual adjustment operations.
Solution Approach 2:
The electronic device detects the aspect ratio of the display area and uses this information to automatically calculate and set the position detection area range. This feedback mechanism ensures that the settings are always optimized for the actual display characteristics, eliminating the need for users to manually adjust settings while maintaining precise aspect ratio matching.
3Loss of time
If automatic aspect ratio adjustment is implemented, then the setting time is reduced, but the device complexity increases
Solution Approach 1:
The electronic device uses its existing display area detection capabilities and communication functions to achieve automatic aspect ratio matching. By utilizing already-present components (display controller, communication interface) for the additional function of automatic position detection area configuration, the system avoids adding significant complexity while achieving time-saving benefits.
Solution Approach 2:
The communication interface acts as an intermediary between the electronic device and the position detection device. It facilitates the automatic transmission of aspect ratio information and configuration settings, enabling coordination between components without requiring complex integrated control mechanisms. This intermediary approach simplifies the overall system architecture while achieving automatic setup.
