Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current content sharing methods between display devices, such as smart glasses and transparent screens, are cumbersome and time-consuming, leading to a poor user experience due to the complexity of establishing communication connections and displaying content in a specific region.

Innovation Solution

A content sharing method and apparatus that determines a projection region on a first display device for a second display device, acquires related information, and displays corresponding content in that region, simplifying the process by adjusting the position of either device to enhance efficiency and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional content sharing method is used (establishing communication connection, sending content, receiving and displaying), then content can be shared between devices, but the process is tedious and time-consuming

Engineering Contradiction:

Improvecontent sharing efficiencyVSAvoidtime for content sharing

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system pre-determines projection regions and establishes spatial relationships between display devices before actual content sharing occurs. By calculating projection regions in advance and pre-positioning display content, the system eliminates the need for complex real-time communication establishment and content transmission, significantly reducing sharing time and improving efficiency

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If traditional content sharing method is used, then content can be shared between devices, but the process is complex and requires multiple steps

Engineering Contradiction:

Improvecontent sharing operation simplicityVSAvoidcontent sharing process complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple discrete steps (connection establishment, content transmission, region determination, and display positioning) into a single integrated projection-based system. By combining these functions into one unified approach where content is directly projected to the determined region, the system simplifies user operation while reducing overall process complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system extracts and eliminates the complex communication connection establishment and content transmission steps from the traditional sharing process. By directly determining projection regions and displaying content in those regions without intermediate transmission steps, the patent removes unnecessary complexity while maintaining content sharing functionality

Inventive Principle:

Principle #2Taking out (Extraction)
