Vehicle Display Redundancy via Dual Data Path Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle display devices lack redundancy in data acquisition and output, leading to information gaps for drivers when sensors or cameras fail, disrupting the assessment of the traffic situation.
Innovation Solution
A method and device that utilize multiple data acquisition and output means connected through separate data lines and processing units, ensuring that information is always available by automatically switching signals to functional outputs, with additional redundancy provided by secondary processing and output units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple data acquisition means and separate data lines are used, then system redundancy is improved, but device complexity increases
Solution Approach 1:
The system is divided into multiple independent data acquisition means (first and second data acquisition means) connected through separate data lines (first and second data lines) to the data output means. This segmentation allows independent operation of each component, ensuring that if one path fails, another can compensate, thereby improving reliability while managing complexity through modular design.
Solution Approach 2:
The patent implements redundancy by providing alternative data paths before failure occurs. The second data acquisition means and second data line serve as pre-prepared backup pathways that can immediately take over if the primary path fails, cushioning against potential system failures and maintaining continuous operation.
2Loss of information
If automatic signal switching is implemented, then information availability is improved, but processing complexity increases
Solution Approach 1:
The data processing unit continuously monitors the status of data signals from multiple acquisition means and automatically switches signal paths based on detected failures or abnormalities. This feedback mechanism ensures that information availability is maintained by dynamically routing signals through functional pathways, while the automation reduces the need for manual intervention despite increased processing complexity.
Solution Approach 2:
The system performs automatic self-diagnosis and self-correction by monitoring its own operational status and autonomously switching between data acquisition paths without external intervention. The data processing unit independently determines when to switch signals, enabling the system to service itself and maintain information flow despite component failures.

AI summary
The method involves transferring a signal of a data detecting unit (12) to a data output unit (10). The signal is output by the data output unit. Detection is made whether another signal or the former signal is received and/or output by the data output unit and a data processing unit (16). The latter signal or the former signal is transmitted to another data output unit when the latter signal or the former signal is not received and/or output by the former data output unit. The latter signal and/or the former signal is received and output by the latter data output unit. The data detecting unit is a camera. The data output unit is a monitor. Independent claims are also included for the following: (1) a display device (2) a motor car.
