Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In power supply devices that convert surrounding radio waves to power, the increased wiring length between power sources and the power supply unit can impair antenna characteristics, leading to reduced power output due to the wiring functioning as an antenna, causing leakage currents and decreased efficiency.
Innovation Solution
The implementation of a power supply device with multiple antennas and AC/DC conversion units, where DC signals are selectively consolidated using consolidating circuits and then converted to a predetermined voltage, reducing wiring length and minimizing power drops by disconnecting low-voltage signals and optimizing the connection of high-voltage signals to minimize leakage currents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If wiring is used to connect each power source with the power supply unit, then power can be transmitted from multiple antennas to the power supply unit, but wiring length increases causing antenna characteristic impairment and power loss
Solution Approach 1:
The patent combines multiple DC signals from different power sources into a single consolidated signal using consolidating circuits. This merging approach eliminates the need for separate wiring connections from each antenna to the power supply unit, thereby reducing total wiring length and preventing antenna characteristic impairment while maintaining power transmission efficiency
Solution Approach 2:
The consolidating circuits serve as intermediary components that receive DC signals from multiple power sources and combine them into a single consolidated DC signal. This intermediary structure reduces wiring requirements by providing a centralized consolidation point, thereby preventing the wiring from acting as parasitic antennas while efficiently transmitting power from multiple sources
2Adaptability or versatility
If wiring length is increased to connect multiple power sources, then all power sources can be connected to the power supply unit, but the wiring functions as an antenna causing leakage currents and decreased efficiency
Solution Approach 1:
The consolidating circuits merge DC signals from multiple power sources into a single consolidated signal, reducing the number of wiring connections required. This eliminates parasitic antenna effects in extended wiring that would cause leakage currents and energy loss, while still enabling multiple power sources to contribute to the overall power output
Solution Approach 2:
The consolidating circuits act as intermediary devices that collect and combine power from multiple sources before transmission to the power supply unit. This intermediary structure minimizes wiring length and prevents energy loss through leakage currents that would occur with extended wiring configurations
