Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video conference systems face issues with overlap in capturing multiple participants, poor network synchronization leading to quality degradation, and inflexibility due to fixed installation requirements, making them unsuitable for group meetings and portable use.
Innovation Solution
A projection-type video conference system incorporating a portable device with a high-definition panoramic camera and projection assembly, powered by a rechargeable battery, which can be controlled via voice instructions and connects seamlessly through a cloud service system for optimal video and audio conferencing without the need for traditional screens or extensive wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hardware-based video conference system is used, then video conference quality is improved, but device cost and installation complexity increase
Solution Approach 1:
The patent combines camera, projection screen, speaker, and microphone into an integrated video conference device. This merging of previously separate hardware components into a single unified device reduces installation complexity while maintaining video conference quality, directly resolving the technical contradiction between reliability and device complexity.
Solution Approach 2:
The integrated device performs multiple functions (video capture, display, audio output, audio input) within a single unit that can be placed on any table surface. This multi-functionality eliminates the need for separate device installation and configuration, reducing installation complexity while preserving conference quality.
2Stability of the object's composition
If a traditional video conference system with fixed installation is used, then video conference stability is improved, but flexibility and portability decrease
Solution Approach 1:
The video conference device is designed with a flexible placement capability, allowing it to be positioned on any table surface rather than requiring fixed installation. This dynamic adaptability enables the device to be easily moved and repositioned while maintaining stable video conference functionality, resolving the contradiction between stability and flexibility.
3Quantity of substance
If multiple participants are captured in a group meeting, then meeting inclusivity is improved, but image overlap and quality degradation occur
Solution Approach 1:
The patent transitions from a traditional 2D flat screen display to a 3D spatial projection system. By projecting the video image onto a vertical surface (wall or screen) in three-dimensional space rather than confining it to a horizontal plane, the system can capture and display multiple participants without image overlap, maintaining image quality while increasing participant inclusivity.
