Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If vehicles with different automated driving levels coexist, then mobility as a service (MaaS) can be provided, but it becomes difficult to provide driving assistance corresponding to different automated driving levels

Engineering Contradiction:

Improvemobility as a serviceVSAvoiddriving assistance system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically adapts the driving assistance functionality based on the automated driving level of each vehicle. The driving assistance device activates or deactivates specific functions according to the detected automated driving level, allowing the system to be versatile across different vehicle types while maintaining appropriate complexity for each level.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Different driving assistance functions are applied to different vehicles based on their specific automated driving level. Each vehicle receives a customized set of assistance functions tailored to its capability level, rather than a uniform system across all vehicles.

Inventive Principle:

Principle #3Local quality

2Extent of automation

If fully automated driving (level 5) is implemented, then human intervention is eliminated, but vehicles with various levels of automated driving must coexist until all vehicles are compatible

Engineering Contradiction:

Improveautomated driving levelVSAvoidcoexistence of different levels

Core Design Contradiction:

Extent of automationVSAdaptability or versatility

Solution Approach 1:

The driving assistance device is designed to universally support multiple automated driving levels (0-5). It can detect the automated driving level of any vehicle and provide appropriate assistance functions, making the system multi-functional and adaptable to the coexistence of different automation levels.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adjusts its behavior based on the automated driving level detected. It can operate in different modes corresponding to different automation levels, enabling seamless coexistence of vehicles with varying levels of automation in the same environment.

Inventive Principle:

Principle #15Dynamics

3Reliability

If driving assistance is provided for all automated driving levels, then comprehensive support is achieved, but system complexity increases

Engineering Contradiction:

Improvedriving assistance coverageVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The driving assistance device dynamically activates only the necessary functions based on the detected automated driving level. This dynamic adaptation ensures comprehensive coverage for all levels while avoiding the complexity of implementing all possible functions simultaneously, as only level-appropriate functions are activated.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Each vehicle receives a customized driving assistance configuration tailored to its specific automated driving level. The system provides locally optimized assistance functions for each vehicle rather than a blanket complex system, achieving reliable support while managing overall system complexity.

Inventive Principle:

Principle #3Local quality
