Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the vehicle operates in manual driving mode, then the driver has full control over the vehicle, but the driver must constantly monitor and intervene in driving tasks, increasing mental workload and reducing convenience

Engineering Contradiction:
ImproveDriver convenienceVSAvoidTime for constant monitoring
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system enables autonomous driving capability where the vehicle performs driving tasks automatically without continuous driver intervention. The controller executes autonomous driving algorithms to handle steering, acceleration, and braking, freeing the driver from constant monitoring while maintaining safety through multiple sensor systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary detection and planning actions through multiple sensors (cameras, LIDAR, radar) to identify obstacles, pedestrians, and road conditions before executing driving maneuvers. This advance preparation allows seamless transition between manual and autonomous modes by having the system ready to take control when needed.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the vehicle switches between manual and autonomous modes, then adaptability to different driving conditions is improved, but system complexity and difficulty of control increase

Engineering Contradiction:
ImproveMode switching capabilityVSAvoidControl system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically adjusts between manual and autonomous driving modes based on real-time environmental conditions and sensor data. The controller continuously evaluates situational parameters and automatically transitions modes when conditions warrant, making the system adaptable without requiring complex manual switching mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control system integrates multiple functions including obstacle detection, path planning, vehicle control, and mode management into a single unified controller. This multi-functional approach handles both manual and autonomous operations through one system, reducing overall complexity compared to separate dedicated systems for each mode.

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

3Reliability

If autonomous driving is implemented, then driving efficiency and safety are improved through learned patterns, but the system requires extensive sensing and communication equipment, increasing device complexity

Engineering Contradiction:
ImproveDriving safetyVSAvoidSensor and communication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system combines multiple sensing technologies (cameras, LIDAR, radar, ultrasonic sensors) and communication systems into an integrated sensor fusion architecture. The controller processes data from all these sources simultaneously, creating a comprehensive environmental model that improves safety while managing complexity through unified processing rather than separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system implements continuous feedback loops where sensor data is constantly monitored, analyzed, and used to adjust driving decisions in real-time. The controller receives feedback from multiple sensors about obstacles, road conditions, and vehicle state, and automatically adjusts autonomous driving parameters to maintain safety and efficiency.

Inventive Principle:
Principle #23Feedback

AI summary

A method for assisted parking of a vehicle performed by a parking control device. The method includes: determining a current position of a vehicle based on at least one of GPS information or environment information of the vehicle; generating traveling map information during manual driving of the vehicle, the traveling map information including a traveling path of the vehicle from the current position of the vehicle, based on at least one user input received through a vehicle manipulation device and at least one sensor value acquired through at least one sensor; and transmitting, based on receiving a rollback request signal, a rollback control signal that causes the vehicle to autonomously drive in a reverse direction along at least part of the traveling path from a rollback starting position of the vehicle.
