Solution Overview
Problem
Current power transmission systems face inefficiencies due to the need for additional charging/discharging devices to manage fluctuating power demands, leading to increased costs and reduced transmission efficiency, especially when dealing with both direct-current and alternating-current powers in small-scale networks.
Innovation Solution
A power transmission system that includes modulators and demodulators connected via a controller, which optimizes power transmission by adjusting the power distribution based on load demands, using code modulation and demodulation schemes to maximize efficiency without relying on additional charging/discharging devices, and coordinates with external systems to manage power shortages and surpluses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional charging/discharging devices are used to manage fluctuating power demands, then power demand management capability is improved, but system cost and device complexity increase
Solution Approach 1:
The power transmitter itself performs the function of managing fluctuating power demands through its controller, which adjusts transmission power based on load demands and optimum power information. This eliminates the need for separate charging/discharging devices, as the transmitter serves both power transmission and power management functions.
Solution Approach 2:
The power transmitter is designed to perform multiple functions: transmitting power, managing power demands, and coordinating with external systems. The single device handles what would traditionally require separate specialized devices, reducing overall system complexity while maintaining adaptability.
2Adaptability or versatility
If additional charging/discharging devices are used to manage fluctuating power demands, then power demand management capability is improved, but transmission efficiency decreases
Solution Approach 1:
The power transmitter directly manages power demand fluctuations without energy loss to intermediate charging/discharging devices. The controller adjusts transmission power efficiently based on real-time load demands, maintaining high transmission efficiency while providing adaptability.
Solution Approach 2:
The patent removes the unnecessary intermediate charging/discharging devices from the power transmission system. By extracting these redundant components, the system achieves both simplified architecture and improved transmission efficiency, as power is transmitted directly from source to load without conversion cycles.
3Loss of energy
If transmission power is limited to optimum power to maximize transmission efficiency, then transmission efficiency is improved, but power supply capability may be insufficient
Solution Approach 1:
The system dynamically adjusts transmission power based on real-time conditions. The controller selects transmission power equal to or smaller than optimum power when loads are served by a single transmitter, but can exceed optimum power when multiple transmitters coordinate. This dynamic approach maintains efficiency while ensuring adequate power supply capability.
Solution Approach 2:
Multiple power transmitters are merged into a coordinated system that can collectively provide power supply capability exceeding the optimum power of any single transmitter. The coordination allows the system to serve larger loads while maintaining overall transmission efficiency through optimized power distribution.
4Power
If multiple power transmitters coordinate to serve loads, then power supply capability is improved, but control complexity increases
Solution Approach 1:
The coordination system uses feedback mechanisms where each transmitter's controller communicates with others to share information about load demands and transmission status. This feedback enables automatic coordination and power distribution, managing the complexity of multiple transmitters through decentralized control rather than centralized management.

AI summary
A power transmission system includes: a power transmitter connected to a power supply; a plurality of power receivers respectively connected to a plurality of loads; a power transmission line connecting the power transmitter and the plurality of power receivers; and a controller. The controller acquires information on optimum power for maximizing transmission efficiency in the power transmission line and information on power demands requested by the loads, and routes transmission power from the power transmitter selectively to the plurality of power receivers. The transmission power is equal to or smaller than the optimum power. When a total power demand is larger than the optimum power, the controller requests another controller to supply supplementary power. When the total power demand is smaller than the optimum power, the controller notifies the other controller that surplus power is available.
