Solution Overview

Problem

The challenge of sharing screens and content between electronic devices is exacerbated by differences in resolution and aspect ratio, leading to suboptimal viewing conditions.

Innovation Solution

A method for optimizing screen sharing by determining the best resolution and aspect ratio for the recipient device, ensuring that the screen and content are shared in the most suitable format.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If screen sharing is performed between devices with different resolutions and aspect ratios, then content can be shared between devices, but the viewing quality and comfort are degraded

Engineering Contradiction:
Improvescreen sharing compatibilityVSAvoiddisplay quality
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The transmitting device dynamically changes display parameters (resolution and aspect ratio) based on the receiving device's capabilities. The system detects the receiving device's screen characteristics and adjusts the transmitted content's resolution and aspect ratio parameters to match, thereby maintaining optimal display quality across different devices while ensuring compatibility.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the transmitting device uses its native resolution for screen sharing, then the source content quality is preserved, but the receiving device cannot display it optimally due to resolution and aspect ratio mismatches

Engineering Contradiction:
Improvesource content qualityVSAvoiddisplay compatibility
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The system performs preliminary detection of the receiving device's resolution and aspect ratio capabilities before initiating screen sharing. Based on this advance knowledge, the transmitting device pre-adjusts the content parameters to match the receiving device's specifications, ensuring both source quality preservation and display compatibility without requiring real-time adjustments during content transmission.

Inventive Principle:
Principle #10Preliminary action
