Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the UE determines and displays device-to-device communication link connections, then the user can select optimal communication links and capabilities, but the device complexity and processing requirements increase

Engineering Contradiction:

Improveability to select communication linksVSAvoidcomplexity of determining and displaying links

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the communication link determination process into distinct components: identifying potential D2D links, determining connection status, and displaying indicators. This modular approach allows the system to handle complexity in manageable stages while maintaining the ability to present multiple communication options to the user.

Inventive Principle:

Principle #1Segmentation

2Productivity

If the system provides real-time indicators of available communication links, then network utilization and user experience improve, but the processing time and energy consumption increase

Engineering Contradiction:

Improvenetwork utilization efficiencyVSAvoidtime for determining and displaying links

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary determination of device-to-device communication link connections before user selection is needed. By pre-identifying potential D2D links and their connection status, the system prepares communication options in advance, reducing the time required when users need to select links and enabling faster response to network conditions.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the UE supports multiple D2D communication technologies (NR-V2X, LTE-V2X, carrier aggregation), then the adaptability and communication capabilities improve, but the device complexity and configuration difficulty increase

Engineering Contradiction:

Improvesupport for multiple communication technologiesVSAvoidcomplexity of managing multiple technologies

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal D2D communication framework that can handle multiple technologies (NR-V2X, LTE-V2X, carrier aggregation) through a common indicator display mechanism. The system provides a unified interface for selecting communication links across different technologies, allowing the UE to support multiple D2D technologies while maintaining consistent user interaction and reducing configuration complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
