Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional simulation methods are used to estimate driver gaze area, then the system can extract ground truth from simulation environment, but the accuracy of verification is low due to limitation of number of simulations

Engineering Contradiction:
Improveaccuracy of careless driving detectionVSAvoidnumber of simulations
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent creates synthetic driver images through image synthesis technology, copying and transforming real driver images to simulate various drowsy states. This allows generating unlimited simulation data without additional physical experiments, thereby improving detection accuracy while maintaining productivity.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system pre-processes driver images to create a comprehensive dataset of drowsy driving scenarios before actual detection. By preparing synthetic images with various hair types, genders, ages, skin colors and expressions in advance, the system ensures high detection accuracy when actual driving occurs.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If verification is performed by creating driver careless state in actual vehicle driving situation, then real-world accuracy can be tested, but there is high risk of accident

Engineering Contradiction:
Improveverification accuracyVSAvoidaccident risk
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces synthetic driver images as an intermediary between real driving and actual driver state verification. These synthesized images serve as a safe mediator that allows verification of careless driving detection without exposing the actual driver to dangerous situations, thus eliminating accident risk while maintaining verification accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of manipulating real drivers in actual vehicles, the system creates copies of driver images through synthesis and applies various transformations to simulate drowsy states. This copying approach enables safe verification of detection algorithms without any physical risk to drivers.

Inventive Principle:
Principle #26Copying

3Measurement precision

If the system applies image synthesis with multiple driver features (hair, gender, age, skin color, expression), then the accuracy of careless driving determination is improved, but the device complexity increases

Engineering Contradiction:
Improveaccuracy of careless driving determinationVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The image synthesis module is designed to handle multiple driver features (hair, gender, age, skin color, expressions) through a unified transformation framework. This multi-functional approach allows the same system to generate diverse synthetic images without requiring separate processing pipelines for each feature, thus improving detection accuracy while controlling complexity.

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

4Reliability

If the smart cruise control processing part controls steering and braking in addition to general functions, then vehicle safety is improved, but the device complexity increases

Engineering Contradiction:
Improvevehicle safetyVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The smart cruise control system dynamically adjusts its control functions based on the detected driver state. When drowsiness is detected, the system automatically activates additional steering and braking controls. This dynamic adaptation allows the system to maintain high safety standards only when needed, avoiding unnecessary complexity during normal driving conditions.

Inventive Principle:
Principle #15Dynamics
