Wireless Energy Harvesting Requests With Charging Time Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack efficient methods for managing energy harvesting requests between devices, leading to inefficiencies in energy conservation and distribution, particularly in scenarios where devices may not receive energy within specified durations.
Innovation Solution
A method and apparatus for wireless communication that allow a first device to request energy from a second device capable of energy harvesting, with an indication of a maximum duration, and for the second device to charge the first device within this duration based on charging rules, while refraining from further charging after the duration expires, and utilizing historical energy request timing information to optimize energy distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device requests energy from another device without time constraints, then the receiving device may have flexibility in energy transfer timing, but the requesting device may experience energy shortage or waste due to delayed energy receipt
Solution Approach 1:
The requesting device performs preliminary actions by sending an energy request message with a maximum duration indication before energy transfer occurs. This allows the receiving device to prepare for energy transfer within the specified time window, ensuring reliable energy receipt while maintaining manageable complexity through structured communication protocols.
2Loss of energy
If the second device continues charging beyond the maximum duration, then the first device may receive more energy than requested, but energy is wasted and the second device loses charging opportunities for other devices
Solution Approach 1:
The system implements feedback mechanisms where the requesting device specifies a maximum duration for energy transfer, and the receiving device monitors and stops charging when this duration is reached. This feedback loop prevents energy waste by ensuring the second device refrains from charging after the maximum duration, while also maintaining high charging throughput by allowing the second device to accept new requests promptly.
3Productivity
If the system uses historical information to optimize energy distribution, then energy allocation efficiency improves, but the system requires more data processing and storage capabilities
Solution Approach 1:
The system performs preliminary data collection by gathering historical information about energy requests and transfers. This historical data is then used to optimize energy distribution decisions, improving efficiency while managing complexity through structured data collection and analysis protocols that build upon established communication frameworks.
