Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If transmit switching is implemented across multiple frequency bands, then communication flexibility and spectral efficiency are improved, but configuration complexity and coordination difficulty increase significantly

Engineering Contradiction:

Improvefrequency band switching capabilityVSAvoidswitching period configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the frequency band configuration by introducing association rules that divide frequency bands into groups with specific switching period relationships. This allows the system to manage multiple frequency bands through structured segmentation rather than treating all bands uniformly, reducing configuration complexity while maintaining versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic switching period configuration where the switching period for each frequency band is determined by association rules that can adapt to different operational scenarios. This dynamic approach allows the system to optimize switching behavior based on current conditions rather than using fixed configurations, resolving the complexity issue while preserving adaptability.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If switching period is configured for each frequency band independently, then transmission flexibility is improved, but coordination between frequency bands deteriorates leading to inefficiencies

Engineering Contradiction:

Improvefrequency band transmission flexibilityVSAvoidfrequency band coordination reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent incorporates feedback mechanisms through association rules that monitor and adjust switching period configurations across frequency bands. The system uses feedback from transmission performance and coordination status to optimize switching periods, ensuring that independent frequency band configurations maintain reliable coordination through continuous adaptation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces association rules as intermediary elements that mediate between independent frequency band configurations. These association rules act as coordinating intermediaries that ensure proper synchronization and coordination between frequency bands while preserving the flexibility of independent configuration, preventing coordination failures.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If more than two frequency bands are used for transmit switching, then spectral efficiency and communication capacity are improved, but switching period management becomes intractable

Engineering Contradiction:

Improvecommunication capacityVSAvoidswitching period management ease

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent creates a universal association rule framework that can manage any number of frequency bands through a consistent set of principles. This multi-functional approach allows the same association rule mechanism to handle two-frequency-band scenarios as well as multi-frequency-band scenarios, making the system scalable and easy to operate regardless of the number of bands involved.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent manages switching period complexity by dynamically changing parameters based on the number of frequency bands in use. The association rules automatically adjust switching period parameters according to the configured frequency band set, transforming a potentially intractable management problem into a parameter-driven solution that scales gracefully with system capacity.

Inventive Principle:

Principle #35Parameter changes
