Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If preconfiguration of transmission resources is used for pilot signals, then resource allocation is simplified, but flexibility is reduced and resource waste occurs

Engineering Contradiction:
Improveresource allocation simplicityVSAvoidtransmission flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by transitioning from static preconfigured resources to dynamic resource allocation. The network device dynamically determines pilot signal transmission resources based on real-time channel conditions and traffic requirements, allowing the system to adapt flexibly while maintaining efficient resource management through centralized control.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If preconfiguration of transmission resources is used for pilot signals, then resource allocation is simplified, but resource waste increases

Engineering Contradiction:
Improveresource allocation simplicityVSAvoidresource waste
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The patent implements feedback mechanisms where the network device monitors channel conditions and pilot signal reception quality, then uses this feedback to dynamically adjust resource allocation for subsequent pilot transmissions. This closed-loop approach ensures resources are allocated only when needed and at optimal levels, eliminating waste while maintaining simple centralized management.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If dynamic resource allocation is implemented for pilot signals, then flexibility is improved, but system complexity increases

Engineering Contradiction:
Improvetransmission flexibilityVSAvoidresource management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces the network device as an intermediary that centralizes the complexity of dynamic resource allocation. The network device receives channel state information, determines optimal pilot transmission resources, and communicates these allocations to terminal devices. This intermediary approach distributes complexity to the network side while keeping terminal devices simple, achieving flexibility without overwhelming system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
