Solution Overview

Problem

Existing screen projecting display technologies fail to adapt the display mode and content to the receiving device's screen size, leading to suboptimal use of larger screens and potential deformation of the projected content.

Innovation Solution

A method and apparatus that determine the display mode of screen projecting content based on the sending device's screen size and generate a target screen projecting content adaptive to the receiving device's screen size, avoiding deformation and fully utilizing the larger screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If screen projecting content is displayed according to the sending device's screen size, then the original display format is maintained, but the receiving device's screen space is not fully utilized and content deformation may occur

Engineering Contradiction:
Improveadaptability to receiving device screen sizeVSAvoiddisplay precision of projected content
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent changes the display parameters (screen size, resolution, aspect ratio) of the projected content to adapt to the receiving device's screen characteristics. The system obtains the receiving device's screen parameters and adjusts the content display parameters accordingly, transforming the content from the original sending device format to match the receiving device's optimal display parameters, thereby resolving the contradiction between adaptability and display precision.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamic adaptation where the display mode and parameters are not fixed but dynamically adjusted based on the receiving device's screen characteristics. The system automatically detects the receiving device's screen size and resolution, then dynamically changes the content rendering parameters to optimize display quality for each specific device, achieving both adaptability and precision simultaneously.

Inventive Principle:
Principle #15Dynamics

2Area of stationary object

If the receiving device's larger screen is fully utilized, then display area is increased, but the original content format may be distorted

Engineering Contradiction:
Improvescreen display areaVSAvoidshape of projected content
Core Design Contradiction:
Area of stationary objectVSShape

Solution Approach 1:

The patent changes the display parameters including aspect ratio, resolution, and scaling factors to match the receiving device's screen characteristics. By adjusting these parameters dynamically based on the receiving device's screen size and shape, the system expands the display area to fully utilize the larger screen while maintaining the original content's aspect ratio and preventing distortion through parameter transformation.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If screen projecting content is rendered according to the sending device's screen size, then the original rendering quality is maintained, but the receiving device's display capabilities are underutilized

Engineering Contradiction:
Improvescreen utilization efficiencyVSAvoidrendering precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent implements dynamic rendering where the rendering precision and quality are adjusted based on the receiving device's display capabilities. The system dynamically determines the optimal rendering parameters by comparing the sending device's original rendering characteristics with the receiving device's screen capabilities, thereby improving screen utilization efficiency while maintaining or enhancing rendering precision through adaptive rendering techniques.

Inventive Principle:
Principle #15Dynamics
