Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to provide a physical electronic device that allows users to extend television screens or channels to portable devices, offering multichannel viewing options, adaptive screen resolutions, and the ability to connect wireless headsets or speakers via Bluetooth or Wi-Fi for audio-only streaming without internet access.
Innovation Solution
A television extender adapter device connected via AV/S-Video/HDMI/DVI/VGA cables, featuring a processing unit for real-time signal processing and output in various resolutions, a broadcasting unit for Wi-Fi or Bluetooth streaming, and a microcontroller for user configuration, enabling multichannel viewing and audio-only streaming on portable devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple televisions are installed to provide multichannel viewing options, then viewing flexibility is improved, but installation cost and device complexity increase significantly
Solution Approach 1:
The patent creates a virtual copy of the television screen output and transmits it via Wi-Fi network to portable devices. Instead of installing multiple physical televisions, the system captures the video signal from one TV and redistributes it digitally to multiple users' devices, providing multichannel viewing flexibility without the cost of multiple TV installations.
Solution Approach 2:
The patent introduces an intermediary system consisting of a capture device, processing unit, and wireless transmission module that mediates between the single television source and multiple portable devices. This intermediary infrastructure enables one TV to serve multiple viewers with different channel preferences, replacing the need for multiple physical TV installations.
2Object-affected harmful factors
If television is kept on mute to ensure silence in the vicinity, then noise level is reduced, but audio content accessibility is lost
Solution Approach 1:
The patent segments the audio-video content delivery by allowing users to choose separate audio and video output paths. Users can route video to their portable devices while directing audio to wireless headphones or speakers, enabling silent viewing environments where audio is privately delivered only to the user through personal audio devices rather than public speakers.
Solution Approach 2:
The patent replaces the mechanical/public audio output system (TV speakers) with wireless digital audio transmission to personal devices. This substitution allows audio content to be delivered electronically to individual users via Bluetooth or Wi-Fi connected headphones/speakers, maintaining silence in the public space while preserving full audio accessibility for each user.
3Illumination intensity
If television screen size is increased to improve visibility for distant viewers, then viewing distance coverage is improved, but space requirements and installation cost increase
Solution Approach 1:
The patent transitions the viewing experience from a single fixed physical dimension (TV screen size) to multiple portable dimensions (smartphones, tablets, laptops). By delivering the video signal to various portable devices with different screen sizes, the system provides visibility options for distant viewers without requiring a larger physical TV installation, utilizing the spatial flexibility of portable devices instead.
4Adaptability or versatility
If adaptive screen resolution is implemented for different portable devices, then compatibility with various screen sizes is improved, but signal processing complexity increases
Solution Approach 1:
The patent implements dynamic signal processing where the system automatically adjusts video resolution and format based on the receiving device's capabilities. The processing unit detects the portable device type and dynamically modifies the video stream parameters (resolution, encoding format) to match the device's display characteristics, providing broad compatibility across different screen sizes while managing processing complexity through automated adaptation.
