2Adaptability or versatility

If overprovisioning of resources is performed to handle dynamic scenarios, then system adaptability improves, but resource utilization efficiency decreases

Engineering Contradiction:
Improvesystem flexibilityVSAvoidresource utilization efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The channel mapping system is designed to be dynamic and adaptable to changing system conditions. The mapping agent can re-evaluate and reconfigure channel mappings in real-time based on current device requirements, signal characteristics, and resource availability, allowing the system to adapt to dynamic scenarios without permanent overprovisioning of resources.
