Solution Overview

Problem

Existing electronic devices with retractable display screens lack an efficient method to dynamically adjust the spacing and number of application icons on the desktop in response to the changing screen size, leading to suboptimal user experience.

Innovation Solution

A device control method that obtains the changing distance of a retractable display screen and adjusts the spacing and number of application icons on the current desktop accordingly, ensuring optimal layout and user interface during screen extension and retraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the retractable display screen is extended or retracted, then the screen size changes, but the application icon layout becomes suboptimal

Engineering Contradiction:

Improvescreen size adaptabilityVSAvoiduser interface usability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The application icon layout is made dynamic by continuously adjusting the spacing and number of icons based on the real-time changing distance of the retractable display screen. The system obtains the changing distance of the screen and dynamically modifies the desktop layout parameters to match the current screen size, ensuring optimal usability across all screen states.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the layout parameters (spacing and number of application icons) in response to screen size changes. Specifically, when the screen extends or retracts, the system calculates the changing distance and adjusts the desktop configuration parameters accordingly, transforming the static icon layout into a adaptive one that responds to screen dimension variations.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If the spacing and number of application icons are fixed, then the layout is simple, but the user experience deteriorates during screen extension and retraction

Engineering Contradiction:

Improveuser experienceVSAvoidlayout adjustment complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system implements a feedback mechanism where the changing distance of the retractable display screen is continuously monitored and fed back to the layout adjustment module. Based on this feedback, the system automatically calculates and applies the appropriate spacing and number of application icons, creating a closed-loop control system that adapts the interface to screen size changes.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent performs preliminary calculations to determine the optimal spacing and number of application icons based on the changing distance of the screen. By pre-establishing the relationship between screen dimensions and layout parameters, the system can quickly adjust the icon layout without complex real-time computations during screen movement.

Inventive Principle:

Principle #10Preliminary action
