Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for seamless transition and redistribution of display content between personal devices and external displays, particularly for users who require larger screens or higher resolutions, such as moving from wearable devices to desktop monitors, while also allowing for collaborative viewing.

Innovation Solution

A method and system that initiates a wireless connection between a primary device and a secondary device, allowing the secondary device to take over display duties, using QR codes, RFID, Bluetooth, or eye-based gestures for initialization, and utilizing protocols like RDMA, RDP, or VNC for remote display sharing, enabling seamless switching between primary and secondary displays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If display content is transferred from personal device to external display, then screen size and resolution are improved, but connection setup complexity increases

Engineering Contradiction:

Improvedisplay screen areaVSAvoidconnection setup complexity

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The system enables automatic connection establishment where the external display autonomously generates QR codes and the mobile device automatically detects and connects to it, eliminating the need for manual configuration steps and making the system self-configuring

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

QR codes serve as an intermediary mechanism that simplifies the connection process by encoding all necessary connection information in a scannable format, allowing automatic parameter extraction and connection establishment without manual intervention

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If wireless connection protocols are implemented for display redistribution, then ease of operation is improved, but energy consumption increases

Engineering Contradiction:

Improvedisplay switching easeVSAvoidenergy consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system employs periodic connection establishment where the mobile device periodically scans for external displays and the connection is activated only when needed, allowing the system to enter low-power states during intervals between usage periods

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The connection state is dynamically adjusted based on usage requirements, allowing the system to transition between active wireless connection and passive/low-power states, optimizing energy consumption according to actual operational needs

Inventive Principle:

Principle #15Dynamics

AI summary

An aspect includes a computer implemented method for display redistribution between a personal display and an external display. The method includes initiating, by a primary device, a wireless connection between a primary device and a secondary device. The primary device includes a primary display and the secondary device includes a secondary display. A confirmation is received at the primary device from the secondary device in response to the initiating. Based on receiving the confirmation, the wireless connection between the primary device and the secondary device is executed. The executing includes utilizing, by the primary device, the secondary display in place of the primary display.
