Solution Overview

Problem

Existing audience response systems face inefficiencies and security concerns in classroom settings due to the manual configuration of camera-equipped wireless devices, which is time-consuming, error-prone, and lacks secure direct connections, affecting student engagement and data privacy.

Innovation Solution

A two-dimensional code-driven method and system for synchronizing camera-equipped wireless computing devices with a centralized computing device, where the centralized device creates a two-dimensional code containing network and device configuration parameters, allowing devices to automatically connect securely without manual input, ensuring direct and private communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual configuration parameters are provided to students for device connection, then students can connect their wireless computing devices to the centralized computing device, but the process is time-consuming and error-prone

Engineering Contradiction:

Improveease of device connectionVSAvoidconfiguration time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The centralized computing device pre-generates a two-dimensional code containing all necessary configuration parameters (IP address, port, password) before the students arrive. This preliminary preparation eliminates the need for students to manually enter configuration data during class setup, reducing both configuration time and errors.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the manual mechanical process of typing configuration parameters with an optical scanning system. Students use their device cameras to scan the two-dimensional code displayed on the centralized device, automatically extracting configuration data through optical recognition rather than manual keyboard entry.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If students manually enter configuration parameters, then they can connect to the network, but typing errors can delay the entire class

Engineering Contradiction:

Improveclassroom efficiencyVSAvoidconnection accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system enables self-service configuration where students autonomously scan the two-dimensional code and automatically receive the correct configuration parameters. This eliminates human error in data entry while maintaining student independence in the connection process, improving both reliability and classroom efficiency.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual keyboard entry is replaced with automated optical scanning and data extraction. The camera-equipped wireless device captures the two-dimensional code image and automatically parses the configuration parameters, eliminating typing errors and ensuring accurate connection setup for all students simultaneously.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If students connect to the wireless network first, then they can find the centralized computing device, but they must manually discover and configure connection parameters

Engineering Contradiction:

Improveease of device discoveryVSAvoidconfiguration complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The centralized computing device prepares the two-dimensional code with all discovery and connection information embedded before students arrive. This preliminary action consolidates network discovery and device configuration into a single scanned code, eliminating the multi-step manual process of finding and configuring the centralized device.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent merges multiple configuration tasks (network connection, device discovery, parameter entry) into a single two-dimensional code scan. All necessary information is consolidated in one location, allowing students to complete the entire connection process through a single action rather than multiple sequential steps.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If proprietary computing devices are supplied by manufacturers, then the audience response system can function properly, but institutions must purchase and configure proprietary devices

Engineering Contradiction:

Improvesystem functionalityVSAvoiddevice compatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The two-dimensional code configuration system is designed to be universally compatible with any camera-equipped wireless computing device that can connect to wireless networks. This universal approach allows students to use their own diverse devices (smartphones, tablets, laptops) rather than requiring proprietary hardware, while maintaining reliable system functionality through standardized configuration delivery.

Inventive Principle:

Principle #6Universality (Multi-functionality)
