Solution Overview

Problem

Existing presentation technologies face challenges such as limited mobility and privacy concerns when using projectors, and online applications suffer from latency issues and security concerns, especially when presenting in unfamiliar locations or with varying network configurations.

Innovation Solution

A closed wireless network is created using a host computing device to securely deliver presentations to client devices without internet access, allowing for full control over the presentation content and ensuring all recipients view the same material, while also providing a stable and secure connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a projector is used for presentation, then the presentation can be displayed on a large surface, but the room must have specific features and configurations, reducing adaptability

Engineering Contradiction:

Improvedisplay brightnessVSAvoidlocation adaptability

Core Design Contradiction:

Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The patent uses mobile computing devices (tablets, laptops) as portable display copies instead of traditional projectors. Each audience member receives a digital copy of the presentation content on their personal device, eliminating the need for projector infrastructure and specialized room configurations.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The presentation system divides the centralized projected display into multiple distributed personal displays. Instead of one large projection screen, each audience member has their own computing device displaying the presentation content, allowing flexible seating arrangements and eliminating room configuration constraints.

Inventive Principle:

Principle #1Segmentation

2Illumination intensity

If a projector is used for presentation, then large-scale display is achieved, but setup time and configuration requirements increase

Engineering Contradiction:

Improvedisplay visibilityVSAvoidsetup time

Core Design Contradiction:

Illumination intensityVSLoss of time

Solution Approach 1:

The system automatically distributes presentation content to audience members' devices without requiring manual setup. The host computing device communicates with client devices to deliver content, eliminating the need for technicians to configure projectors, screens, and seating arrangements before each presentation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The presentation software is pre-installed on both host and client devices, and content is prepared in advance. When a presentation begins, the system automatically initiates content distribution, eliminating on-site configuration time for projectors and display equipment.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If online applications are used for presentation, then presentations can be delivered remotely, but latency and network dependency reduce reliability

Engineering Contradiction:

Improveremote delivery capabilityVSAvoidconnection stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system uses a local wireless network as an intermediary between the host and client devices, creating a closed presentation environment that does not depend on external internet connections. This local network mediation eliminates latency issues associated with remote online applications while maintaining the ability to deliver presentations remotely.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of connecting to external online services that require internet access, the system creates a self-contained local wireless network where the host device acts as the content source and client devices receive content locally, inverting the traditional client-server model that depends on external networks.

Inventive Principle:

Principle #13The other way round (Inversion)

4Adaptability or versatility

If online applications are used for presentation, then remote access is enabled, but security concerns with data traveling over external networks increase

Engineering Contradiction:

Improveremote accessibilityVSAvoidnetwork security risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system creates a closed, isolated wireless network environment for presentation delivery that is independent of external networks. This inert communication environment prevents unauthorized access and data interception by external parties, eliminating security risks associated with data traveling over public or corporate networks.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

AI summary

Systems, methods and computer readable memory devices for delivering a presentation are provided. In one example, a method includes communicatively coupling the host computing device to an external router, and establishing the closed wireless network using the router. An encrypted communication session is established via the closed wireless network with a plurality of client computing devices that each comprises a display. Each of the client computing devices is communicatively coupled to a virtual network server on the host computing device. Frame buffer data is retrieved from a storage subsystem of the host computing device. The frame buffer data is sent to each of the client computing devices to modify the display of each device.
