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

VSEngineering Contradiction Analysis

1Power

If processor and memory are replaced to upgrade performance, then system performance is improved, but user experience-based data is lost

Engineering Contradiction:
Improvesystem performanceVSAvoiduser experience-based data
Core Design Contradiction:
PowerVSLoss of information

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.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If detachable device replacement is implemented, then system upgradability is improved, but data security during transmission and storage becomes more critical

Engineering Contradiction:
Improvesystem upgradabilityVSAvoiddata security risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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.

Inventive Principle:
Principle #10Preliminary action

3Duration of action of stationary object

If memory is divided into partitions, then memory lifespan is extended, but system complexity increases

Engineering Contradiction:
Improvememory lifespanVSAvoidmemory partitioning complexity
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation
