Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user opens an app and navigates to display a two-dimensional code, then the code can be displayed, but the operation process becomes cumbersome and time-consuming
Solution Approach 1:
The system pre-configures the two-dimensional code display function and sensor monitoring capabilities. When the user performs a wrist turning action, the system has already prepared the necessary code data and display parameters, enabling immediate display without requiring the user to navigate through apps or menus beforehand.
Solution Approach 2:
The patent replaces the mechanical interaction of manually opening apps and navigating menus with an automatic gesture-based trigger system. The gyroscope and acceleration sensors detect the wrist turning action and automatically initiate the two-dimensional code display, eliminating the need for manual navigation through application interfaces.
2Productivity
If the system automatically displays two-dimensional code upon gesture detection, then the process becomes simple and efficient, but the device complexity increases due to sensor integration and gesture recognition algorithms
Solution Approach 1:
The gyroscope and acceleration sensors serve multiple functions: they detect the wrist turning gesture, determine the orientation of the two-dimensional code, and trigger the display timing. This multi-functionality reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity while maintaining high productivity.
Solution Approach 2:
The patent introduces a gesture recognition system as an intermediary layer between the sensor hardware and the two-dimensional code display. This intermediary process translates raw sensor data into meaningful gestures and automatically manages the code display timing and orientation, simplifying the user interaction while the system handles the complexity internally.
3Extent of automation
If the system uses sensor data to detect wrist turning actions, then the code display becomes automatic and gesture-based, but the measurement precision requirements increase for accurate gesture recognition
Solution Approach 1:
The patent combines data from multiple sensors (gyroscope and acceleration sensors) to detect the wrist turning action. By merging the rotational information from the gyroscope with the linear acceleration data, the system achieves more reliable and accurate gesture recognition, reducing the precision requirements for individual sensors while maintaining high automation levels.

AI summary
Embodiments of this application provide a method for displaying a two-dimensional code and an electronic device. The method is performed by an electronic device, and includes: obtaining first sensor data, where the first sensor data is collected at a first moment; if it is determined, based on the first sensor data, that a first action of a user corresponding to the first moment is a preset action, determining whether the user performs a wrist turning action within a preset duration range starting from the first moment; and displaying a preset two-dimensional code page when the user performs a wrist turning action within the preset duration range. In the method, a process of presenting a two-dimensional code by the user can be simple and efficient.
