Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If autonomous driving systems use traditional detection methods, then they can detect road conditions, but they cannot detect potholes and cracks in real time

Engineering Contradiction:
Improveroad surface damage detection capabilityVSAvoidreal-time detection response time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical or manual road inspection methods with an optical imaging system. A sensor (camera) captures road surface images, and an image detection algorithm processes these images to identify potholes and cracks. This substitution enables real-time detection with high precision, resolving the contradiction between detection capability and response time.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates a visual copy of the road surface through imaging sensors and processes this copy digitally using image detection algorithms. This allows the system to analyze road conditions without physical contact, enabling real-time detection while maintaining high measurement precision for pothole and crack identification.

Inventive Principle:
Principle #26Copying

2Reliability

If autonomous driving vehicles do not detect road surface damage, then the system is simpler, but safety risks increase due to rollovers or collisions

Engineering Contradiction:
Improveautonomous driving safetyVSAvoiddetection system complexity
Core Design Contradiction:

Solution Approach 1:

The patent makes the sensor serve multiple functions: it captures images for both general autonomous navigation and specific road surface damage detection. The image processing system handles multiple tasks including pothole detection, crack detection, and road condition assessment. This multi-functionality improves safety without proportionally increasing device complexity.

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

Solution Approach 2:

The patent introduces an image detection algorithm as an intermediary between the sensor and the autonomous driving control system. This intermediary layer processes visual information to identify road surface damage and translates it into actionable data for the driving system, enhancing safety while managing complexity through modular architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If autonomous driving systems detect road surface damage, then safety improves, but the system requires complex image processing algorithms

Engineering Contradiction:

Solution Approach 1:

The patent segments the road surface image into different regions and applies targeted detection algorithms to identify specific features such as potholes, cracks, and other damages. This segmentation approach improves detection accuracy by focusing computational resources on relevant features while managing algorithmic complexity through divided processing tasks.

Inventive Principle:
Principle #1Segmentation

Solution Approach 1:

The patent detects road surface damage in advance before the vehicle reaches it. By identifying potholes and cracks ahead of time, the system can prepare appropriate responses such as speed adjustment or path modification. This preliminary action allows the vehicle to maintain high productivity while avoiding poor ride experiences by addressing bumps before they affect passengers.

Inventive Principle:
