Integrated Intercom Audio Mixing for Space-Limited UTV Dashboards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UTV systems require a choice between a traditional stereo system with loudspeakers or an intercom system, lacking the ability to integrate both functionalities effectively due to space constraints in the dashboard.
Innovation Solution
An integrated audio system that separates the intercom unit from the dashboard and connects it to the stereo head unit's output, allowing simultaneous use of both systems by intercepting the stereo's output signal and integrating it passively until needed for communication, with active control via a remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional stereo system with loudspeakers is installed in the UTV dashboard, then music playback capability is provided, but the intercom system cannot be integrated due to space constraints
Solution Approach 1:
The system separates the intercom unit from the dashboard and places it outside the vehicle, while keeping the stereo head unit in the dashboard. This segmentation allows both systems to coexist without competing for dashboard space, resolving the contradiction between functionality and space constraints.
Solution Approach 2:
The stereo head unit is designed to serve dual purposes: it functions as both a music playback device and an intercom communication unit. By integrating the intercom functionality into the existing stereo head unit, the system achieves multi-functionality without requiring additional dashboard space.
2Adaptability or versatility
If both intercom system and stereo system are integrated in the dashboard, then both communication and music playback are enabled, but dashboard space is exceeded
Solution Approach 1:
The intercom unit is extracted from the dashboard and placed outside the vehicle. This extraction allows the stereo head unit to handle both music playback and intercom functions, eliminating the need for additional dashboard space while maintaining full system functionality.
Solution Approach 2:
The system transitions from a two-dimensional dashboard layout to a three-dimensional configuration where the intercom unit is positioned outside the vehicle. This dimensional change allows both systems to coexist without spatial conflict within the dashboard.
3Area of stationary object
If the intercom unit is placed outside the dashboard, then dashboard space is freed, but the integration with stereo system becomes more complex
Solution Approach 1:
The stereo head unit acts as an intermediary between the external intercom unit and the vehicle's audio system. It receives audio signals from the intercom unit and routes them to the appropriate output devices, simplifying the integration complexity despite the external placement of the intercom unit.
Solution Approach 2:
The system replaces complex mechanical routing with electronic signal processing. The stereo head unit uses electronic circuits to route audio signals between the intercom unit, speakers, and other audio components, reducing the complexity of physical connections and integration.

AI summary
There is disclosed a communication device. The communications device includes an audio head unit for generating audio from an audio source, an intercom system for receiving and broadcasting intercom audio over a channel already used for the source audio thereby creating a combined audio, a plurality of headsets to generate playback audio, and where the source audio is temporarily lowered within the combined audio during broadcast of the intercom audio.
