Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If static connectivity configuration is used with single cellular connection, then device complexity is reduced, but reliability deteriorates when primary connection fails

Engineering Contradiction:

Improveconnection availabilityVSAvoidconnectivity management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system transitions from static connectivity configuration to dynamic connectivity management, where the data traffic controller continuously monitors performance data from multiple cellular networks and automatically steers traffic between them based on real-time conditions, ensuring optimal connection availability without manual intervention

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The connectivity management system operates autonomously by self-monitoring performance data from multiple carriers and self-steering traffic between them based on predefined policies and real-time network conditions, eliminating the need for manual intervention while maintaining high reliability

Inventive Principle:

Principle #25Self-service

2Loss of time

If manual intervention is required to switch connectivity provider, then device complexity is reduced, but loss of time increases during connection failures

Engineering Contradiction:

Improveswitching timeVSAvoidautomatic carrier switching

Core Design Contradiction:

Loss of timeVSExtent of automation

Solution Approach 1:

The system establishes multiple cellular connections to different carriers in advance before any failure occurs, and maintains them in a ready state with performance monitoring already active, enabling immediate failover without waiting for failure detection or manual configuration

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The data traffic controller continuously receives performance data from multiple cellular networks, analyzes connection status in real-time, and automatically triggers carrier switching when performance thresholds are breached, eliminating manual intervention and reducing switching time

Inventive Principle:

Principle #23Feedback

3Reliability

If connection to multiple cellular networks is established, then reliability is improved, but device complexity increases

Engineering Contradiction:

Improveconnection availabilityVSAvoidmulti-network management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system separates connectivity management into distinct functional components: multiple cellular network interfaces for redundancy, a data traffic controller for centralized intelligence, and an automotive edge router for traffic steering, allowing each component to be optimized independently while working together to manage multiple networks efficiently

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The data traffic controller acts as an intermediary between multiple cellular network interfaces and the automotive edge router, centralizing the complexity of multi-network management in a single intelligent component that monitors all connections and makes automated routing decisions, simplifying the overall system architecture

Inventive Principle:
