Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle electronics systems face challenges in maintaining optimal performance due to external factors affecting audio quality, as they lack knowledge of the current vehicle state or changes in vehicle state, leading to noise, masking, or corruption of audio signals.
Innovation Solution
A vehicle electronic module that monitors vehicle-state information through a communication bus, analyzes this data, and adjusts communication processing parameters to improve audio quality by determining and updating processing parameters based on the vehicle's environment.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the electronic module operates with fixed processing parameters, then the device complexity is reduced, but the audio quality deteriorates due to noise and environmental factors
Solution Approach 1:
The patent implements dynamic adjustment of processing parameters based on real-time vehicle state detection. The system transitions from static fixed parameters to dynamic adaptive parameters that change according to environmental conditions, vehicle motion state, and audio signal characteristics, thereby improving audio quality without requiring permanent system complexity
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring vehicle state through sensors and using this information to adjust processing parameters. The feedback loop includes detecting vehicle state, analyzing audio signals, determining optimal parameters, and updating the processing configuration, which improves audio quality while managing complexity through automated control
2Object-affected harmful factors
If the electronic module continuously monitors and adjusts processing parameters, then the audio quality is improved, but the use of energy increases
Solution Approach 1:
The system applies partial monitoring and adjustment by selectively updating processing parameters based on significant vehicle state changes rather than continuous full-scale adjustment. It monitors all vehicle state parameters but only triggers processing parameter updates when necessary, thereby improving audio quality while reducing unnecessary energy consumption
Solution Approach 2:
The system changes processing parameters adaptively based on detected vehicle state and audio signal characteristics. By dynamically adjusting parameters such as noise suppression levels, echo cancellation strength, and equalization settings only when needed, the system improves audio quality while minimizing energy usage compared to continuous full-power processing
