Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If energy harvesting and data communication use the same threshold for resource selection, then the system complexity is reduced, but energy harvesting efficiency deteriorates
Solution Approach 1:
The patent divides the single threshold for resource selection into two separate thresholds: one for energy harvesting (first threshold) and one for data communication (second threshold). This segmentation allows independent optimization of each function's resource selection criteria, enabling the energy harvesting process to use metrics specifically tailored to its efficiency requirements without being constrained by data communication thresholds, thereby resolving the contradiction between system complexity and energy harvesting efficiency.
Solution Approach 2:
The patent applies different threshold values and selection criteria locally to different functions: energy harvesting resources are selected based on a first threshold derived from energy harvesting metrics, while data communication resources use a second threshold. This local differentiation optimizes each function's performance independently, allowing energy harvesting to achieve higher efficiency through function-specific parameters without increasing overall system complexity.
2Productivity
If preferred resources for energy transfer are selected based on energy harvesting metrics, then energy harvesting efficiency is improved, but resource allocation complexity increases
Solution Approach 1:
The patent segments the resource pool into preferred resources and non-preferred resources based on energy harvesting metrics compared against a first threshold. This segmentation creates a clear classification mechanism that simplifies the allocation process: resources meeting the threshold criterion are automatically designated as preferred, eliminating the need for complex multi-criteria evaluation and reducing resource allocation complexity while maintaining high energy harvesting efficiency.
Solution Approach 2:
The patent changes the selection parameter from a single unified threshold to a first threshold specifically derived from energy harvesting metrics. This parameter change enables straightforward comparison and classification of resources based on energy-related characteristics, simplifying the allocation decision process while optimizing energy harvesting performance through metric-specific criteria.
3Ease of operation
If a single threshold is used for both energy harvesting and data communication, then the system operation is simplified, but energy transfer efficiency deteriorates
Solution Approach 1:
The patent segments the threshold management into two independent threshold systems: a first threshold for energy harvesting resource selection and a second threshold for data communication resource selection. This segmentation maintains ease of operation by keeping each threshold management simple and independent, while simultaneously improving energy transfer efficiency through optimized, function-specific threshold criteria that are tailored to energy harvesting requirements.
Solution Approach 2:
The patent applies local quality by using a first threshold specifically optimized for energy harvesting operations and a second threshold for data communication. This local optimization allows energy transfer efficiency to be improved through metric-appropriate thresholds without complicating the overall system, as each threshold operates independently with its own simplicity.

AI summary
Apparatus, methods, and computer program products for supporting energy harvesting (EH) wireless devices are provided. An example method may include receiving energy harvesting information associated with at least one second network entity. The example method may further include transmitting, for the at least one second network entity, a first information indicative of a first set of preferred resources for an energy transfer or a first set of non-preferred resources for the energy transfer, where the first set of preferred resources is associated with a first metric above a first threshold for energy harvesting, where the first set of non-preferred resources is associated with a second metric below the first threshold, where the first threshold is based on the energy harvesting information, and where the first threshold is independent of a second threshold for data communication.
