Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical wireless charging and data transmission systems lack efficiency and effectiveness due to the inability to adapt to contextual properties of devices and environments, often resulting in impractical, wasteful, or harmful provision of power and data.
Innovation Solution
A controller is used to select and adapt the functions of transmitter nodes to optimize energy and data transmission by considering properties of the receiver device, system, and environment, allowing for directional and proportional adjustment of charging power and data transmission based on contextual information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If optical wireless charging and data transmission are provided simultaneously without adaptation to contextual properties, then both functions can be provided, but efficiency is reduced and energy waste occurs
Solution Approach 1:
The system dynamically adapts the function and parameters of transmitter nodes based on contextual properties. The controller adjusts whether nodes provide charging, data transmission, or both functions simultaneously, and modifies beam directions and power levels in real-time according to receiver location, system state, and environmental conditions. This dynamic adaptation optimizes charging efficiency while minimizing energy waste.
Solution Approach 2:
The system changes operational parameters including beam direction angles, power transmission levels, and function allocation based on contextual information. By adjusting these parameters according to receiver device properties, system state, and environmental factors, the system achieves optimal charging efficiency and reduces energy consumption.
2Power
If high power is used for wireless charging, then sufficient power levels can be provided to charge devices, but health hazards increase
Solution Approach 1:
The system directs high-power charging beams precisely toward receiver devices using directional control, while other areas receive minimal or no radiation. By localizing the high-power transmission only where needed and for the minimum necessary duration, the system provides sufficient charging power while minimizing exposure and health hazards in surrounding areas.
Solution Approach 2:
The controller monitors system state and receiver device properties in real-time, adjusting power levels dynamically. When a receiver is detected, high power is directed toward it; when no receiver is present or the device is fully charged, power is reduced or redirected. This feedback-based control ensures sufficient power transfer while minimizing unnecessary high-power exposure and associated health risks.
3Reliability
If optical wireless charging and data transmission are provided without contextual adaptation, then basic functionality is maintained, but system effectiveness is reduced
Solution Approach 1:
Transmitter nodes are designed to perform multiple functions - wireless charging, data transmission, or both simultaneously - based on contextual needs. The controller allocates functions dynamically among nodes, allowing the system to adapt to different scenarios without requiring separate dedicated systems. This multi-functionality approach enhances system effectiveness while managing complexity through centralized control.
