Solution Overview

Problem

Existing conference devices cannot perform operations like writing and recording during video conferences, leading to low effective utilization rates and inefficient summarization of key points.

Innovation Solution

A display device with independently controlled first and second display modules, allowing for synchronous or independent display, and equipped with a master component and OPS component for expanded functionality, including touch functionality and remote control diversity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single display module is used for video conference projection, then the device structure is simple, but the device cannot perform other operations such as writing and recording simultaneously

Engineering Contradiction:
Improvefunctional versatilityVSAvoiddisplay module structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display device is divided into two independent display modules: a first display module for video conference projection and a second display module for writing and recording operations. Each module can be independently controlled and operated, allowing simultaneous execution of different functions without interfering with each other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display device is designed to support multiple functions through its dual display module architecture. The first display module handles projection tasks while the second display module handles writing and recording tasks, enabling the single device to perform diverse operations that would otherwise require multiple separate devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If key points are written on a blackboard one by one after the conference, then the process is complete, but the efficiency is affected due to the troublesome process

Engineering Contradiction:
Improvesummarization efficiencyVSAvoidtime for summarizing key points
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The second display module enables key points to be recorded and summarized in real-time during the video conference projection, rather than requiring post-conference transcription. This preliminary action captures information while it is still fresh in participants' minds and allows immediate extraction and organization of key points.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If participants carry notebooks to record key points, then the recording function is achieved, but the effective utilization rate of the conference device is low

Engineering Contradiction:
Improvedevice utilization rateVSAvoidexternal equipment requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The writing and recording functions are merged into the display device itself through the second display module, eliminating the need for external notebooks or separate recording devices. This integration allows participants to use the conference device for both projection and note-taking, thereby increasing its effective utilization rate.

Inventive Principle:
Principle #5Merging (Combining)
