Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current car audio aftermarket lacks the ability to safely add aftermarket audio systems to electric vehicles and hybrids due to insufficient power supply and integration challenges with existing vehicle control systems, particularly for high-power audio equipment.
Innovation Solution
A wireless audio system comprising a transmitter unit powered by the vehicle and battery-powered speaker units that receive audio signals wirelessly, allowing for synchronous playback without drawing significant power from the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional wired aftermarket audio equipment is installed in EVs or hybrids, then audio power output can be increased, but the vehicle's power system becomes insufficient and installation complexity increases
Solution Approach 1:
The patent replaces the traditional mechanical/wired audio system with a wireless audio system. The wireless audio device receives audio signals wirelessly from the vehicle's head unit and transmits them to external speakers, eliminating the need for complex wiring installations and dashboard modifications while providing sufficient audio power for EVs and hybrids.
2Power
If alternator size is increased to power upgraded audio equipment in ICE vehicles, then audio power capacity is improved, but vehicle cost and complexity increase
Solution Approach 1:
The patent introduces a wireless audio device as an intermediary component that bridges the vehicle's head unit and external speakers. This intermediary handles audio signal processing and wireless transmission, allowing high-power audio output without requiring modifications to the vehicle's power system or installation of larger alternators.
3Adaptability or versatility
If dashboard is dismantled to add custom wiring for aftermarket audio, then audio system customization is improved, but installation time and complexity increase
Solution Approach 1:
The patent replaces the mechanical wiring installation process with a wireless communication system. The wireless audio device communicates with the head unit and external speakers through wireless signals, eliminating the need to dismantle the dashboard or install custom wiring while maintaining full audio system customization capabilities.
4Power
If wired aftermarket audio equipment is installed to achieve high power output, then audio performance is improved, but the ability to safely add equipment to EVs and hybrids is reduced
Solution Approach 1:
The patent replaces the power-dependent wired audio system with a wireless audio system that receives signals wirelessly from the vehicle's existing head unit. This approach provides high-power audio output capability while being universally compatible with EVs, hybrids, and traditional vehicles, as it does not require modifications to the vehicle's power system.
