Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a uncrewed aerial system connects to a single mobile communication network, then the device complexity is low, but the reliability and service continuity of command and control communications deteriorate

Engineering Contradiction:
Improvereliability of command and control communicationsVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the communication connectivity by dividing it into two separate mobile communication networks with different network identifiers. This segmentation allows the uncrewed aerial system to distribute communication traffic across multiple networks, thereby improving reliability without requiring complete system redundancy. Each network segment can operate independently, ensuring service continuity if one network fails.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The uncrewed aerial system is configured with multi-functionality by enabling it to operate with multiple mobile communication networks simultaneously. The system can selectively use either network for command and control communications based on availability and quality, making the communication system universal rather than network-specific. This multi-functionality approach improves reliability while managing complexity through standardized protocols.

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

2Reliability

If a uncrewed aerial system uses dual subscription functionality with two mobile communication networks, then the reliability and service continuity improve, but the device complexity increases

Engineering Contradiction:
Improveservice continuityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary action by pre-configuring dual subscription functionality with two mobile communication networks before actual operation. The uncrewed aerial system is prepared with multiple network identifiers and authentication credentials in advance, allowing it to quickly switch between networks or maintain simultaneous connections without requiring complex real-time decision-making. This pre-preparation reduces operational complexity while ensuring service continuity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary layer in the form of a uncrewed aerial system application enabler server that mediates between the application layer and multiple mobile communication networks. This intermediary handles the complexity of managing dual subscriptions, network selection, and connectivity configuration, thereby improving service continuity while shielding the core system from excessive complexity. The intermediary abstracts the multi-network management into standardized interfaces.

Inventive Principle:
Principle #24Intermediary (Mediator)
