Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Most multimedia devices lack built-in cameras and microphones, requiring users to manually add these components via wires or wireless connections, which can be cumbersome and require precise alignment and frequency matching for distortion-free video communication.
Innovation Solution
A multimedia device that connects to a mobile device with a camera and microphone via a wireless network, obtains hardware configuration information, and transforms data to be compatible with both the mobile device and a remote communication device, enabling seamless video communication without the need for additional hardware on the multimedia device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If camera and microphone are manually added to multimedia device via wires or wireless connections, then video communication capability is achieved, but device complexity and setup difficulty increase
Solution Approach 1:
The patent uses the mobile device as an intermediary to provide camera and microphone capabilities to the multimedia device. Instead of physically connecting additional hardware to the multimedia device, the system leverages the mobile device's existing camera and microphone through wireless communication, thereby achieving video communication capability without increasing the multimedia device's hardware complexity or setup difficulty
Solution Approach 2:
The mobile device serves multiple functions: it acts as both the video communication endpoint and the source of camera/microphone capabilities for the multimedia device. This multi-functionality eliminates the need for separate dedicated hardware components and simplifies the overall system architecture
2Manufacturing precision
If camera with perfect angle and focus is used, then video quality is improved, but device complexity and alignment requirements increase
Solution Approach 1:
The mobile device's camera automatically performs focus adjustment and angle optimization without requiring manual intervention. The device's operating system and camera application handle alignment and focus calibration automatically, eliminating the need for complex manual alignment procedures while maintaining high video quality
Solution Approach 2:
The system dynamically adjusts camera parameters such as focus distance, exposure, and angle through software control rather than requiring precise physical alignment. This allows the camera to adapt to different shooting conditions and maintain optimal video quality without complex mechanical adjustment mechanisms
3Reliability
If wide radio frequency band is used for audio and video transmission, then transmission quality is improved, but device complexity and frequency matching requirements increase
Solution Approach 1:
The system implements automatic frequency and signal quality monitoring with real-time adjustment capabilities. The mobile device and multimedia device continuously monitor transmission quality and automatically adjust frequency parameters to maintain optimal connection, eliminating the need for manual frequency matching while ensuring high transmission quality
Solution Approach 2:
The radio frequency parameters are made dynamic rather than static, allowing the system to automatically adapt to changing wireless conditions. The connection parameters are continuously optimized based on signal quality, interference levels, and device movement, maintaining reliable transmission without requiring complex manual frequency configuration
