Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If terminal identities are assigned to remote terminals in end-to-end connections, then message forwarding accuracy is improved, but system complexity increases

Engineering Contradiction:
Improvemessage forwarding accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The terminal identity is segmented into two parts: a first identity part and a second identity part. The first identity part is used for identifying the remote terminal in the sidelink connection, while the second identity part is used for identifying the remote terminal in the end-to-end connection. This segmentation allows the relay terminal to accurately forward messages by using appropriate identity parts for different communication scenarios, without requiring a completely new identity assignment system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The relay terminal acts as an intermediary that receives terminal identities from the network device and distributes them to remote terminals. The relay terminal also uses these identities to forward messages between remote terminals. This intermediary approach centralizes the identity management function, reducing the complexity burden on individual terminals while maintaining accurate message forwarding capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If terminal identities are determined and distributed through relay terminals, then communication stability is improved, but resource consumption increases

Engineering Contradiction:
Improvecommunication stabilityVSAvoidresource consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The network device determines and assigns terminal identities to remote terminals before the actual end-to-end communication begins. The relay terminal receives and stores these identities in advance, so that when message forwarding is needed, the identities are already available. This preliminary assignment avoids the need for real-time identity negotiation during communication, reducing resource consumption while maintaining communication stability.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If terminal identities are assigned for end-to-end connections, then message routing accuracy is improved, but information management complexity increases

Engineering Contradiction:
Improvemessage routing accuracyVSAvoidinformation management complexity
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

Different parts of the terminal identity are used in different communication contexts. The first identity part is used locally in the sidelink connection between the relay terminal and the remote terminal, while the second identity part is used in the end-to-end connection context. This local quality differentiation allows each part of the identity to serve its specific purpose efficiently, reducing the overall information management complexity while maintaining routing accuracy.

Inventive Principle:
Principle #3Local quality
