Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lighting control systems are limited to simple on/off operations and lack advanced control features, failing to provide sophisticated lighting solutions that can be synchronized with audio signals or vehicle events, which restricts the ability to create immersive and dynamic lighting experiences within the vehicle cabin.
Innovation Solution
An audio bus lighting control device that receives audio bus data and generates lighting control signals to control multiple lighting elements, allowing for advanced features such as mood settings, color changes, and synchronization with audio signals and vehicle events, using a controller and switching circuitry to manage pulse width modulated outputs and decode control information for red, green, and blue lighting panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vehicle lighting control systems are used, then the system structure is simple and easy to implement, but the lighting control functionality is limited to basic on/off operations without advanced features
Solution Approach 1:
The audio bus lighting control device is designed to perform multiple functions: it controls lighting elements based on audio signals, synchronizes lighting with music beats, provides mood lighting modes, and responds to vehicle events. This multi-functional approach allows a single device to replace what would traditionally require separate control systems, thereby improving adaptability while managing complexity through integration.
Solution Approach 2:
The invention introduces an audio bus as an intermediary communication channel between the audio system and lighting control system. Instead of requiring direct complex wiring between audio signals and lighting controls, the audio bus serves as a mediator that carries control data, simplifying the overall system architecture while enabling sophisticated lighting control capabilities.
2Illumination intensity
If conventional lighting elements with single color and simple control are used, then the hardware requirements are minimal and installation is straightforward, but the lighting effects are basic and cannot provide immersive experiences
Solution Approach 1:
The system controls individual lighting elements or groups of elements with different color and intensity characteristics at different locations. By assigning specific color temperatures, brightness levels, and dynamic behaviors to different lighting zones, the system creates varied and immersive lighting effects throughout the vehicle interior without requiring uniform complex hardware everywhere.
Solution Approach 2:
The lighting system transitions from static on/off control to dynamic control that responds to audio signals in real-time. Lighting elements can change color, brightness, and timing based on music beats, creating dynamic and engaging lighting effects. This dynamic behavior is achieved through software control algorithms that process audio data and translate it into lighting commands.
3Ease of operation
If separate electrical backbone is provided for each lighting element, then the control precision for each element is high, but the system complexity and wiring requirements increase significantly
Solution Approach 1:
The invention merges multiple control functions into a single integrated audio bus lighting control device. Instead of having separate control circuits for each lighting element, the system combines audio signal processing, control logic, and lighting driver functions into one unified device that communicates with lighting elements through the audio bus, thereby reducing wiring complexity while maintaining control precision.
Solution Approach 2:
The audio bus serves as a universal communication channel that carries both audio signals and lighting control data. This multi-functional use of the audio bus eliminates the need for dedicated control wiring for lighting elements, as the same bus infrastructure is used for both audio playback and lighting control, significantly reducing wiring requirements.
