In-Car Music Analysis for Synchronized Seat Vibration and Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle onboard systems lack comprehensive analysis of music signals, leading to monotonous and inconsistent control of seat and lighting effects, as they primarily focus on basic features without integrating control methods.
Innovation Solution
A vehicle onboard control method that analyzes music signals to extract multi-level features such as basic features, change points, beat points, music structure, and attributes, generating control signals for synchronized vibration and lighting effects based on a preset generation rule template.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If basic music features (energy, rhythm, timbre) are used for control, then the control system is simple to implement, but the audio experience becomes monotonous and lacks immersion
Solution Approach 1:
The patent segments music analysis into multiple hierarchical levels: basic features (energy, rhythm, timbre), intermediate features (beat points, change points, music structure), and advanced features (music attributes, music style). This segmentation allows the system to progressively extract more comprehensive control signals from music, transforming the simple control approach into a multi-layered analysis framework that enhances audio experience while maintaining systematic implementation
Solution Approach 2:
The patent adds new dimensions to music analysis by introducing temporal dimensions (beat points, change points), structural dimensions (music structure segmentation), and stylistic dimensions (music attributes and style). This multi-dimensional expansion transforms the control system from basic feature processing to comprehensive music interpretation, resolving the contradiction between implementation simplicity and experience quality
2Ease of manufacture
If seat and lighting are controlled separately based on music information, then each component can be independently optimized, but the overall user experience consistency deteriorates
Solution Approach 1:
The patent merges seat control and lighting control into a unified music-based control system. Both components are controlled by the same multi-level music analysis results, including basic features, beat points, change points, and music structure. This merging ensures that seat vibrations and lighting effects are synchronized and consistent with each other and with the music, resolving the experience consistency issue while still allowing independent optimization of each component's response characteristics
Solution Approach 2:
The patent creates a universal music analysis framework that serves multiple control functions simultaneously. The same music feature extraction process generates control signals for both seat and lighting systems, making the control system multi-functional. This universal approach ensures consistent user experience across different components while maintaining the ability to independently optimize each component's behavior
