Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If statistical traffic information is used for determining traffic data, then the system can provide traffic predictions, but the accuracy of travel time predictions deteriorates due to outdated information

Engineering Contradiction:

Improveaccuracy of traffic dataVSAvoidoutdated statistical information

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines statistical traffic information with real-time condition data (weather, speed traps, road works) to create a hybrid traffic data determination system. This merging allows the system to maintain the benefits of historical patterns while incorporating current conditions, thereby improving accuracy without losing time efficiency

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system pre-calculates modification coefficients based on historical statistical data and stores them for quick retrieval. When real-time condition data becomes available, these pre-prepared coefficients are rapidly adjusted rather than calculated from scratch, reducing processing time while maintaining accuracy

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If real-time condition data is incorporated to improve traffic data accuracy, then measurement precision improves, but device complexity increases due to additional data sources and processing requirements

Engineering Contradiction:

Improveaccuracy of traffic dataVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces modification coefficients as an intermediary element that bridges statistical traffic information and real-time condition data. These coefficients simplify the integration process by providing a standardized mechanism to adjust historical data based on current conditions, reducing the complexity of directly combining multiple diverse data sources

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes parameters by introducing modification coefficients that adjust statistical traffic data based on condition data. Instead of fundamentally restructuring the data determination process, the patent modifies existing parameters (traffic data values) through multiplicative coefficients, maintaining system simplicity while improving accuracy

Inventive Principle:

Principle #35Parameter changes
