In-Vehicle Media Player Sensor Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-car entertainment systems lack the ability to dynamically modify media content based on real-time travel duration and user preferences, leading to driver distraction and inefficiencies in content selection and download, particularly in situations where the remaining content duration exceeds travel time.
Innovation Solution
A computer-implemented method that receives input signals from car sensors to generate modified media content by filtering or adjusting the content based on remaining trip duration, passenger demographics, and current media consumption, allowing for seamless playback and optimized content selection and download.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the in-car entertainment system provides full media content without modification, then the content quality and completeness are maintained, but the driver distraction increases and road safety decreases
Solution Approach 1:
The system automatically selects and modifies media content based on sensor data without requiring driver interaction. The navigation system self-determines the remaining trip duration and the entertainment system self-adjusts the content playback parameters accordingly, eliminating the need for driver intervention in content selection
Solution Approach 2:
The system pre-calculates the appropriate media content and playback parameters before the driver needs to interact with the system. By continuously monitoring sensor data and pre-determining content modifications based on remaining trip duration, the system prepares everything in advance, allowing the driver to simply enjoy the pre-selected content without distraction
2Reliability
If the system downloads high-resolution streaming content to avoid interruptions, then the entertainment continuity is improved, but the power consumption increases significantly
Solution Approach 1:
Instead of downloading the entire high-resolution content, the system downloads only the portion of content that will be played during the remaining trip duration. The system calculates the exact time needed and downloads proportionally less content, reducing power consumption while maintaining entertainment continuity for the actual travel period
Solution Approach 2:
The system dynamically adjusts the content resolution and download quantity based on the remaining trip duration parameter. When the remaining time is short, the system lowers the content resolution and downloads less data, optimizing the balance between entertainment continuity and power consumption according to the specific travel conditions
3Measurement precision
If the navigation system and entertainment system are integrated with real-time data sharing, then the content selection accuracy is improved, but the device complexity increases
Solution Approach 1:
The navigation system serves dual purposes: it provides route guidance and simultaneously provides timing data for the entertainment system. By making the navigation system multi-functional, the patent avoids adding a separate dedicated timing device, thus improving content selection accuracy without proportionally increasing system complexity
Solution Approach 2:
The patent merges the navigation system and entertainment system into an integrated architecture where they share common hardware resources and data buses. The systems are combined such that the navigation module's timing information is directly accessible to the entertainment module, improving precision while reducing overall system complexity through resource sharing
