In-Vehicle Infotainment System With Detachable Memory For Data Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle infotainment systems face limitations in upgrading processors and memories, leading to loss of user experience-based data when equipment is replaced, and lack efficient methods for securely storing and transmitting such data.
Innovation Solution
An in-vehicle infotainment system with detachable devices that include a first device with a first memory, a second device with a second memory, and an interface for electrical connection, allowing for the execution of applications based on user-customized data, secure encryption, and partitioning of memory to extend its lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If processor and memory are replaced to upgrade performance, then system performance is improved, but user experience-based data is lost
Solution Approach 1:
The patent divides the storage system into two separate components: a first storage device that retains user experience-based data and a second storage device that holds processor and memory components. This segmentation allows the processor and memory to be replaced for performance upgrades while preserving user data in the first storage device, thus resolving the contradiction between system performance improvement and data retention.
2Adaptability or versatility
If detachable device replacement is implemented, then system upgradability is improved, but data security during transmission and storage becomes more critical
Solution Approach 1:
The patent introduces an intermediary mechanism that facilitates safe data transfer between storage devices during replacement. The system includes a controller that manages the transfer process, ensuring data integrity and security when the second storage device is replaced, thus enabling upgradability while mitigating security risks.
Solution Approach 2:
Before replacing the second storage device, the system performs preliminary actions to backup and securely transfer user experience-based data from the first storage device to a safe location. This preliminary data preservation ensures that data security is maintained throughout the replacement process, allowing upgradability without compromising information safety.
3Duration of action of stationary object
If memory is divided into partitions, then memory lifespan is extended, but system complexity increases
Solution Approach 1:
The patent segments the memory into multiple partitions, with at least one partition dedicated to storing user experience-based data. This segmentation strategy extends memory lifespan by distributing wear across different partitions, allowing selective replacement of only the second storage device while preserving data in the first partition, thus balancing extended durability with manageable system complexity.
