Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current car entertainment systems with central control boxes increase complexity and are not efficient for sharing video and audio signals between display units without a central hub.
Innovation Solution
A vehicle entertainment system with display devices that can share audio and video signals either through cables or a wireless network, powered by a power filter connected to the vehicle power, allowing for decentralized operation without a central control box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a central control box is used to distribute audio and video signals between display devices, then signal distribution capability is improved, but system complexity increases
Solution Approach 1:
The patent removes the central control box from the system architecture. Each display device is equipped with its own media player and signal processing capabilities, allowing independent operation and direct peer-to-peer signal sharing without requiring a centralized distribution unit. This extraction of the central control function eliminates the associated complexity while maintaining signal distribution capability through decentralized means.
Solution Approach 2:
The system divides the previously centralized control functions into separate segments distributed across individual display devices. Each display device contains its own media player, processor, and control logic, creating modular independent units that can operate autonomously or cooperatively. This segmentation eliminates the need for a central control box while preserving overall system functionality.
2Ease of operation
If display devices are connected through a wireless network, then system installation ease is improved, but potential signal loss or interference increases
Solution Approach 1:
The system dynamically selects between wireless and wired connection modes based on operational requirements. Display devices are equipped with both wireless communication capabilities and physical cable interfaces, allowing the system to adaptively choose the most appropriate connection type for each situation, thereby optimizing both installation convenience and signal reliability as needed.
3Adaptability or versatility
If each display device has its own media player, then device functionality is improved, but manufacturing cost increases
Solution Approach 1:
Each display device is designed with a universal media player that can handle multiple media formats and functions (video playback, audio processing, wireless communication, wired connections). This multi-functional design consolidates what would otherwise require separate components, achieving enhanced device functionality while controlling manufacturing costs through component consolidation and standardization.
Data Source
AI summary
An entertainment system including one or more display devices. Each display device may have a media player to play the content of a disc or media inserted in the media player. Each display device may also have a storage unit to store the media content. The media content can be shared between different display devices. The connection between display devices can be either by plurality of cables or by a wireless network. Each display device receives its power from a power filter. The power filter is connected to a power source.
