Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional remote controllers are used to control electronic devices with diverse functions, then the electronic device can perform multiple functions, but the user interface becomes complicated and difficult to control efficiently
Solution Approach 1:
The patent creates a virtual copy of the electronic device's display interface on the mobile terminal's touch screen. The touch screen displays a reproduced image of the electronic device's screen, allowing users to interact with virtual representations of buttons, sliders, and other UI elements. This copying approach simplifies control by presenting a familiar, intuitive interface on the portable device while maintaining full functionality of the electronic device.
Solution Approach 2:
The mobile terminal acts as an intermediary between the user and the electronic device. Instead of directly controlling the electronic device with a traditional remote, the user interacts with the touch screen interface, which then transmits control signals to the electronic device. This intermediary layer provides a more intuitive and versatile control mechanism while maintaining compatibility with the electronic device's existing functions.
2Ease of operation
If a touch device is used to control electronic devices, then ease of operation improves, but coordinate matching between touch area and display area must be precisely established
Solution Approach 1:
The system establishes bidirectional communication between the mobile terminal and electronic device to exchange coordinate information. The electronic device provides feedback about its display area coordinates, and the mobile terminal uses this information to accurately map touch screen coordinates to the corresponding display area coordinates. This feedback mechanism ensures precise coordinate matching without requiring high manufacturing precision.
Solution Approach 2:
The patent dynamically adjusts coordinate transformation parameters based on the specific device configurations. By establishing an absolute coordinate system and calculating transformation relationships between the touch screen and display area, the system adapts to different screen sizes, resolutions, and orientations. This parameter adjustment approach allows flexible coordination mapping without stringent manufacturing tolerances.
