Solution Overview

Problem

Current presentation systems in classroom or conference settings require multiple disparate devices that are difficult to integrate, leading to potential errors and high costs, with existing document cameras, interactive whiteboards, and audience response systems lacking efficient real-time feedback and video transmission capabilities.

Innovation Solution

A mobile device integrating a tablet computer with a miniaturized document camera, wireless video transmitter and receiver, and audience response system receiver, allowing for wireless and real-time video and image capture and display, as well as feedback collection and analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple disparate devices (document camera, personal computer, interactive whiteboard, audience response system) are used together, then functional capabilities are improved, but device complexity and integration difficulty increase

Engineering Contradiction:

Improvefunctional capabilitiesVSAvoidintegration difficulty

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines a document camera, display screen, and audience response system into a single integrated device. The document camera captures images, the display screen shows them, and the audience response system collects feedback, all within one unified apparatus rather than requiring separate devices for each function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated device performs multiple functions simultaneously: it captures documents and 3D objects via the document camera, displays visual content on the screen, collects real-time audience feedback through the response system, and provides wireless connectivity. This multi-functional design eliminates the need for multiple separate devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple disparate devices are connected to a personal computer, then system functionality is achieved, but potential errors and connection problems increase

Engineering Contradiction:

Improvesystem functionalityVSAvoidconnection stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

By integrating the document camera, display, and audience response system into one device, the patent eliminates multiple connection points and interfaces that would otherwise need to connect to a personal computer. This reduces the number of potential connection failures and integration errors.

Inventive Principle:

Principle #5Merging (Combining)

3Loss of information

If traditional document cameras and presentation systems are used, then video capture is achieved, but real-time wireless transmission and feedback capabilities are limited

Engineering Contradiction:

Improvevideo capture capabilityVSAvoidreal-time feedback efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The integrated audience response system provides real-time feedback from viewers to the presenter. The system collects responses wirelessly, displays them on the screen, and enables immediate interaction, creating a closed-loop feedback system that enhances real-time communication and engagement.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces traditional wired connections and mechanical interaction methods with wireless technology. The document camera, display, and audience response system communicate wirelessly, eliminating physical cables and enabling more flexible, mobile deployment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If separate devices are used for presentation and feedback collection, then specialized functions are maintained, but cost and hardware requirements increase

Engineering Contradiction:

Improvespecialized functionsVSAvoidhardware quantity

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent merges the document camera, display screen, and audience response system into a single integrated device, reducing the total quantity of hardware from multiple separate devices to one unified system while maintaining all specialized functions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated device provides universal functionality by combining document capture, visual display, and audience interaction capabilities in one apparatus, eliminating the need for separate specialized devices for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)
