Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent introduces a base station as an intermediary device between terminal devices to establish indirect signal transmission paths. The base station receives signals from terminals and forwards them to target terminals, acting as a mediator that improves transmission reliability while maintaining manageable system complexity through centralized coordination.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements dynamic selection between direct and indirect transmission modes based on real-time channel conditions. The system adaptively switches transmission paths depending on electromagnetic parameter changes and hardware feature variations, optimizing reliability without requiring complex permanent infrastructure.

Inventive Principle:
Principle #15Dynamics

2Reliability

If relayed connection is established through another terminal device, then signal transmission reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesignal transmission reliabilityVSAvoidcommunication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses base stations as intermediary relay points rather than relying on terminal-to-terminal relaying. This approach improves reliability by using more capable infrastructure devices as mediators while keeping terminal device complexity low through standardized base station interfaces and protocols.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The base station serves multiple functions including direct communication with terminals, relaying signals between terminals, and coordinating transmission parameters. This multi-functionality consolidates complexity in the base station while keeping the overall system efficient and reliable.
