Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If developers manually design layout files for each device specification, then the display interface can be precisely adapted to each device, but the development time and labor cost increase significantly
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting layout parameters based on device specifications. Instead of creating separate layout files for each device, the system uses a single layout file with parameters that automatically adapt to different device sizes, resolutions, and characteristics. This resolves the contradiction by maintaining precise layout adaptation while eliminating the time-consuming manual design process for each device variant.
Solution Approach 2:
The patent implements universality by designing a single layout file that serves multiple device specifications. The layout file contains device-agnostic control definitions with automatic adaptation logic that makes it universally applicable across different head unit specifications. This eliminates the need for multiple device-specific layout files, significantly reducing development time while maintaining adaptability.
2Manufacturing precision
If developers create separate layout files for each device specification, then the layout precision for each device is high, but the development complexity and difficulty increase
Solution Approach 1:
The system maintains layout precision by using parameterized control definitions that automatically adjust to device specifications. The layout file contains parameters for control size, position, and other attributes that are dynamically calculated based on device characteristics, ensuring precise layouts without requiring separate files for each device.
Solution Approach 2:
The patent applies self-service by enabling the layout system to automatically generate device-specific layouts without manual intervention. The system reads device specifications and automatically calculates the appropriate layout parameters, eliminating the need for developers to manually design and maintain multiple layout files for different devices.
3Adaptability or versatility
If multiple layout files are created for different devices, then each device gets optimized layout, but the storage space and maintenance effort increase
Solution Approach 1:
The patent reduces storage requirements by replacing multiple device-specific layout files with a single universal layout file. This single file contains all the necessary control definitions and adaptation logic to serve multiple device specifications, significantly reducing the quantity of layout data that needs to be stored and maintained.
Solution Approach 2:
The system merges multiple device-specific layout configurations into a single unified layout file. By combining all device adaptations into one file with parameterized controls and automatic adjustment logic, the system eliminates redundant layout data while maintaining the ability to optimize layouts for different devices.

AI summary
This application provides a display interface layout method and an electronic device. A preset initial layout file may be displayed on a development interface by using an application development tool. A developer may add one or more control units to the initial layout file, and set an attribute constraint condition of the control unit, to obtain a first layout file that corresponds to a first display interface and that is in a first application. An attribute value of the control unit is obtained by a running device of the first application through calculation based on the corresponding attribute constraint condition. Subsequently, the running device of the first application may calculate an attribute value of each control unit based on the attribute constraint condition set in the first layout file, to automatically complete layout and display of the first display interface based on the attribute value of each control unit.
