Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional route planning methods are used that only consider route length and travel time, then the routing system remains simple and fast, but the route accuracy and network coverage optimization are suboptimal

Engineering Contradiction:
Improveroute accuracyVSAvoidrouting system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by collecting and storing signal strength data from multiple vehicles in advance, creating a database of geographical regions with varying signal qualities before route planning is needed. This pre-collected data is then quickly retrieved during route planning, improving accuracy without adding significant computational complexity during the routing decision process

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary database that stores signal quality data collected from vehicles. This database acts as a mediator between the complex data collection process and the simple route planning algorithm, allowing traditional routing methods to be enhanced with connectivity information without directly increasing the complexity of the routing system itself

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If real-time signal strength data from multiple vehicles is collected and processed, then the route planning accuracy and network coverage are improved, but the data processing complexity and computational requirements increase

Engineering Contradiction:
Improveconnectivity reliabilityVSAvoiddata processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Signal strength data from multiple vehicles is collected and stored in a database in advance, before route planning is performed. This pre-processing of connectivity data eliminates the need for complex real-time calculations during routing, as the system only needs to query pre-analyzed signal quality information for different geographical regions

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses data that is already available from vehicles through their existing connectivity infrastructure. Vehicles naturally generate and transmit signal strength data as part of their normal operation, and the route planning system leverages this self-generated data without requiring additional specialized sensors or complex data collection mechanisms

Inventive Principle:
Principle #25Self-service

3Loss of information

If vehicle data is logged and transmitted to cloud computing units, then valuable statistics for network enhancement are obtained, but the data transmission and processing overhead increases

Engineering Contradiction:
Improveinformation retentionVSAvoiddata transmission energy
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The system extracts only the essential signal strength and positional data from vehicle telemetry streams, separating this critical connectivity information from other vehicle data. By extracting only the necessary parameters for route planning, the system minimizes data transmission overhead while retaining the most valuable information for improving route accuracy and network coverage analysis

Inventive Principle:
Principle #2Taking out (Extraction)
