Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If WiFi connectivity is required to access SOA services, then service access reliability is improved, but device operation complexity increases and user convenience deteriorates

Engineering Contradiction:

Improveservice access reliabilityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the SOA service request data into multiple data packets that can be transmitted through different communication channels (WiFi and Bluetooth Low Energy). This segmentation allows the system to bypass the requirement of connecting to vehicle WiFi by using BLE as an alternative transmission path, thereby improving user convenience while maintaining service access reliability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces Bluetooth Low Energy as an intermediary communication channel between the external terminal and the vehicle system. This intermediary enables data transmission without requiring connection to the vehicle's WiFi network, simplifying the connection process while ensuring reliable service access through the alternative BLE pathway

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If WiFi connection is required before vehicle startup, then network connectivity is improved, but system adaptability deteriorates

Engineering Contradiction:

Improvenetwork connectivityVSAvoidsystem adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic communication strategy where the system can adaptively switch between WiFi and Bluetooth Low Energy communication channels based on the vehicle's operational state. Before vehicle startup, BLE is used for communication; after startup, WiFi can be utilized. This dynamic approach enhances system adaptability across different operational phases while maintaining reliable network connectivity

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the communication parameter (transmission channel) based on the vehicle's power state. By transitioning from BLE-only communication before startup to potentially WiFi-based communication after startup, the system adapts to different operational conditions, improving both connectivity reliability and system versatility

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If SOA service data is transmitted through a single channel, then transmission simplicity is improved, but communication efficiency deteriorates

Engineering Contradiction:

Improvetransmission simplicityVSAvoidcommunication efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent segments the SOA service request data into multiple data packets and distributes them across different communication channels (BLE and WiFi). This segmentation enables parallel transmission of data packets, significantly improving communication efficiency by utilizing multiple pathways simultaneously while managing transmission complexity through systematic packet handling

Inventive Principle:

Principle #1Segmentation

4Use of energy by moving object

If vehicle power-on is required for service access, then energy consumption is improved, but user experience deteriorates

Engineering Contradiction:

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent enables preliminary service interactions before the vehicle is fully powered on by utilizing Bluetooth Low Energy communication. Users can access certain SOA services and receive information through BLE in the pre-startup phase, improving user experience by allowing early interaction without requiring the vehicle to be powered on, thereby avoiding unnecessary energy consumption
