Three-Way Cable Assembly for Karaoke Audio Video Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable arrangements for connecting music/video sources to karaoke systems and televisions are wasteful, cluttered, and inconvenient, as they often require separate devices for amplification, display, and control, and lack a three-way capability for analog audio and video signals.
Innovation Solution
A three-way cable assembly with a 3.5 mm phone plug for connecting to audio/video sources, featuring separate conductors for left-audio, right-audio, video, and ground, allowing for connection between music/video players, karaoke devices, and televisions, with intermediate cables to route signals effectively between these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate devices are used for amplification, display, and control in karaoke systems, then device functionality is comprehensive, but device complexity and clutter increase
Solution Approach 1:
The cable assembly is designed to perform multiple functions simultaneously: it carries both audio signals (left and right channels) and video signals through a single connector interface. This multi-functional cable replaces what would traditionally require separate audio cables and video cables, thereby reducing device complexity and clutter while maintaining comprehensive functionality for connecting karaoke systems to televisions or audio equipment
2Ease of operation
If traditional point-to-point cable arrangements are used, then connection simplicity is maintained, but three-way capability for analog audio and video signals is lacking
Solution Approach 1:
The patent combines audio and video signal transmission into a single cable assembly with a unified connector structure. The connector integrates multiple conductors that simultaneously carry left audio, right audio, and video signals, enabling a single connection point to handle both audio and video pathways. This merging approach maintains connection simplicity while achieving three-way capability for analog signal distribution
3Reliability
If separate audio and video cables are used, then signal transmission reliability is maintained, but cable arrangement clutter increases
Solution Approach 1:
The cable assembly merges multiple signal transmission functions into a single integrated cable. Inside the unified cable structure, separate conductors maintain independent audio and video signal pathways, ensuring reliable transmission for each signal type while preventing signal interference. The external appearance is a single organized cable rather than multiple separate cables, significantly reducing visual and physical clutter in the cable arrangement

AI summary
A karaoke device is included within an enclosure and having a voice pickup element integrated into the enclosure for converting sound waves into an electrical signal. An audio input signal from a DVD player passes into the enclosure and into an electronic circuit for amplifying the electrical signal, for controlling the amplitude of the electrical signal and for mixing the electrical signal and the audio input signal into a mixed audio signal. The resulting audio output signal is delivered to an output device such as a television.
