VSEngineering Contradiction Analysis

1Productivity

If frequency bands are densely utilized to improve communication capacity, then productivity increases, but interference among different radio systems worsens

Engineering Contradiction:

Improvecommunication capacityVSAvoidinterference among radio systems

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic frequency hopping where the first radio network changes its frequency band over time based on information from the second radio network. This dynamic adjustment allows the system to adapt to changing interference conditions while maintaining high communication capacity, resolving the contradiction between dense frequency utilization and interference avoidance

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The control unit changes the frequency band parameter of the first radio network based on information received from the second radio network. By dynamically changing this critical parameter, the system can maintain high productivity while avoiding harmful interference through parameter optimization

Inventive Principle:

Principle #35Parameter changes

2Reliability

If frequency hopping is performed to reduce interference, then reliability improves, but device complexity increases

Engineering Contradiction:

Improveinterference avoidanceVSAvoidfrequency hopping control

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a communication unit as an intermediary that receives frequency band information from the second radio network and transmits it to the control unit. This intermediary structure simplifies the overall system architecture by centralizing the frequency hopping control logic, thereby improving reliability while managing device complexity through modular design

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback control where the control unit receives information about the second radio network's frequency band usage and uses this feedback to adjust the first radio network's frequency hopping pattern. This feedback mechanism ensures reliable interference avoidance while keeping the control logic manageable through information-based decision making

Inventive Principle:
