Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If device information is exchanged using existing communication protocols between head units and mobile devices, then connection can be established, but device characteristics and capabilities are not properly communicated leading to suboptimal interworking

Engineering Contradiction:
Improveinterworking reliabilityVSAvoiddevice characteristic information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent applies preliminary action by including device information in connection establishment messages before the actual service interaction occurs. The head unit or mobile device embeds device characteristics, capabilities, and identification information in the initial connection request or response messages, ensuring that both parties have complete information before commencing service operations. This prevents information loss and enables reliable interworking from the outset.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If mobile devices maintain data paths for mobile communication networks when connected to head units, then network connectivity is preserved, but connection management becomes complex and inefficient

Engineering Contradiction:
Improvenetwork connection flexibilityVSAvoidconnection management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the data path configuration adaptive rather than static. The system dynamically determines whether to maintain mobile communication network data paths or use head unit data paths based on device information exchanged during connection establishment. The mobile device can switch between different connection modes (maintaining mobile network path vs. using head unit path) depending on the service requirements and head unit capabilities, optimizing connection management without sacrificing flexibility.

Inventive Principle:
Principle #15Dynamics

3Reliability

If applications are manually executed on mobile devices for head unit interworking, then device compatibility can be verified, but user convenience is reduced

Engineering Contradiction:
Improveapplication compatibilityVSAvoiduser operation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies self-service by enabling automatic application execution based on exchanged device information. The head unit or mobile device automatically determines which applications need to be executed for interworking based on the device characteristics and capabilities communicated during connection establishment. This eliminates the need for manual user intervention while ensuring that the correct applications are executed for reliable interworking, thereby improving both compatibility and user convenience.

Inventive Principle:
Principle #25Self-service
