Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If standalone Telematics Data processing system is used for monitoring driving behavior, then the system can be implemented, but the accuracy in determining vehicle type and user role is insufficient

Engineering Contradiction:
Improveaccuracy of vehicle type and user role determinationVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the determination process into multiple independent classification models: one for vehicle type identification and another for user role identification. Each model processes specific features independently, improving accuracy without requiring a monolithic complex system. The segmentation allows parallel processing of different data types (motion statistics, sound data, driving patterns) to determine vehicle type and user role separately.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs a multi-functional approach where a single telematics system performs multiple functions: collecting motion statistical data, analyzing sound data, identifying vehicle type, determining user role, and monitoring driving behavior. This universal system consolidates what would otherwise require separate specialized systems, achieving high accuracy across multiple parameters without proportionally increasing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If existing methods are used for driving behavior monitoring, then basic monitoring is possible, but continuous and automated monitoring with high accuracy is not achieved

Engineering Contradiction:
Improvecontinuous and automated monitoring capabilityVSAvoidaccuracy of drive related information
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system implements self-service automation where the classification models automatically process incoming data streams without human intervention. The system autonomously identifies vehicle types and user roles by processing motion statistical data, sound data, and driving patterns in real-time. This automated self-service capability enables continuous monitoring while maintaining high accuracy through machine learning-based classification rather than manual assessment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system ensures continuous monitoring by continuously processing data streams from sensors and microphones without interruption. The classification models operate continuously to update vehicle type and user role determinations, enabling uninterrupted driving behavior monitoring. This continuous action maintains high accuracy by constantly analyzing new data rather than relying on periodic or intermittent assessments.

Inventive Principle:
Principle #20Continuity of useful action

3Measurement precision

If multiple data types are collected for determination, then accuracy improves, but the device complexity and data processing requirements increase

Engineering Contradiction:
Improveaccuracy of drive related information determinationVSAvoiddata processing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments data processing into distinct modules: one module processes motion statistical data, another processes sound data, and a third processes driving pattern data. Each segment feeds into specialized classification models that handle specific data types independently. This segmentation manages complexity by organizing multiple data streams into separate, manageable processing channels rather than mixing all data together.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces classification models as intermediary components between raw data collection and final determination. These intermediary models process and transform multiple data types into standardized outputs for vehicle type and user role identification. The intermediaries simplify the overall system by providing a structured interface between diverse data sources and the decision-making logic, reducing the complexity of directly integrating all data types.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A system (1) for determining a drive related information (10, 11) for a commutation being carried out by a user in a vehicle. The system includes a first processing unit (6) which receives and processes a motion statistical data (3), a driving pattern data (4), or, a sound data (5), or combination thereof based at least on one or more of trained machine learning models (7, 8, 9) to determine the drive related information (10, 11) for the commutation being carried out by the user in the vehicle. The motion statistical data (3) is derived from acceleration and/or speed of a vehicle at various instances during a trip. The driving pattern data (4) is related to driving patterns of a driver and/or a driving behaviour of a driver. The sound data (5) is related to statistical pattern, or frequency profile derived using a microphone kept inside the vehicle.
