Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video conference systems face issues such as overlap and synchronization distortions due to independent audio and video devices, limited suitability for group conferences, and the need for fixed installations with cumbersome wiring, making them unsuitable for flexible use.
Innovation Solution
A portable projection-type video conference device integrating a liftable camera assembly for panoramic video capture, an audio input assembly for 360-degree sound collection, and a projection assembly for high-definition image display, connected via cloud services for seamless video conferencing without the need for wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large screen conference system with TV screen and camera is used, then video conference capability is provided, but overlap phenomenon occurs when too many people are present and synchronization distortion happens due to independent audio and video devices
Solution Approach 1:
The patent combines the camera assembly, projection assembly, audio input assembly, and audio output assembly into a single integrated device. The camera is embedded in the housing and can be lifted to a predetermined position, while the projection assembly projects images onto a screen. The audio input and output assemblies are integrated with the same synchronization control mechanism, ensuring all components work together without synchronization distortion.
2Adaptability or versatility
If a large screen conference system with fixed installation is used, then video conference function is achieved, but cumbersome wiring and fixed location requirements reduce convenience
Solution Approach 1:
The integrated conference device serves multiple functions: the camera assembly captures video, the projection assembly displays images, the audio input assembly collects voice signals, and the audio output assembly broadcasts sound. All these functions are combined in one portable device that can be moved to different locations without requiring fixed installation or extensive wiring.
3Ease of operation
If a small screen conference system is used, then portability is improved, but the limited screen size and camera viewing angle make it unsuitable for group conferences
Solution Approach 1:
The patent transitions from a small direct-view screen to a projection-based display system. The projection assembly projects images onto a separate screen, effectively expanding the display area from the limited size of a portable device screen to a large projection screen. This allows the device to maintain portability while providing large-format display suitable for group conferences.

AI summary
A projection-type video conference device comprises a camera assembly configuring to acquire a panoramic video of a conference scene, an audio input assembly configuring to collect voice signals of the conference scene, a projection assembly configuring to display images or information of a conference video and an audio output assembly configuring to broadcast a voice signal of the projection assembly or a voice signal of the audio input assembly, wherein the camera assembly is embedded in a housing of the projection-type video conference device and is liftable. And a projection-type video conference system comprises projection-type video conference devices which are connected with each other.
