Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device uses sensor-identified direction for satellite alignment, then the device can operate without conventional wireless networks, but the alignment accuracy deteriorates due to discrepancies between sensor direction and antenna direction
Solution Approach 1:
The system continuously monitors the alignment status by comparing satellite signal quality with the current device orientation, and provides real-time feedback through on-screen arrows indicating the direction and magnitude of adjustment needed. This closed-loop feedback mechanism enables the device to iteratively improve alignment accuracy despite initial sensor inaccuracies.
Solution Approach 2:
The patent replaces complex mechanical alignment systems with software-based solutions. Instead of using precision mechanical gyroscopes or external alignment tools, the system uses standard sensors combined with software algorithms to calculate and guide alignment, substituting mechanical precision requirements with computational processing.
2Measurement precision
If the electronic device provides detailed on-screen guidance for angle adjustment, then the alignment accuracy improves, but the user interface complexity increases
Solution Approach 1:
The system performs self-alignment by automatically calculating the required adjustments and providing step-by-step guidance without requiring external tools or complex user interpretation. The user simply follows the on-screen instructions, and the system manages all the computational complexity of determining optimal orientation internally.
Solution Approach 2:
Instead of requiring the user to understand complex angular measurements and manually adjust the device, the system inverts the approach by calculating the exact adjustment needed and presenting simplified visual guidance (arrows and range indicators). The complexity is reversed from user-side calculation to system-side calculation with simplified user output.
3Reliability
If the electronic device requires precise azimuth and elevation angle alignment, then the satellite connection stability improves, but the ease of operation deteriorates due to difficult manual adjustment
Solution Approach 1:
The system provides continuous feedback during the alignment process through visual indicators showing whether the device is within the acceptable angle range. The dynamic arrows and range indicators guide the user step-by-step, making the operation intuitive despite the precision requirements. This feedback loop transforms a difficult manual adjustment task into a guided process.
Solution Approach 2:
The on-screen visual indicators act as an intermediary between the complex internal alignment requirements and the user's simple rotational movements. Instead of directly exposing the user to complex angular parameters, the system uses intuitive visual metaphors (arrows pointing in adjustment direction, colored indicators showing range compliance) that mediate the interaction.

AI summary
This electronic device may comprise: a memory for storing instructions; a display; a communication circuit; and at least one processor. When executed individually or collectively by the at least one processor, the instructions can cause the electronic device to: display, on the basis of identifying an azimuth angle of the electronic device with respect to a satellite outside a first range, a first screen for adjusting the azimuth angle to be located within the first range; while the first screen is displayed, display, on the basis that the azimuth angle outside the first range is changed to be within the first range, a second screen, which is changed from the first screen and guides the electronic device to be fixed; and, while the second screen is displayed, display, on the basis of identifying an elevation angle of the electronic device with respect to the satellite outside a second range, a third screen, which is changed from the second screen and is for adjusting the elevation angle to be located within the second range.
