Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If AC current is transmitted through power cords to AC-powered devices, then electrical power is delivered to the devices, but electromagnetic fields and radio frequency interference are generated that adversely affect device performance
Solution Approach 1:
The patent introduces a DC voltage generator and DC current plates as an intermediary system between the AC power source and the AC-powered device. The DC voltage generator creates a DC electromagnetic field that acts as a mediator to counteract the harmful AC electromagnetic fields and radio frequency interference, thereby protecting the sensitive electronics while maintaining power delivery
Solution Approach 2:
The patent applies preliminary anti-action by generating a DC electromagnetic field in advance that opposes and neutralizes the harmful electromagnetic fields and interference before they can adversely affect the AC-powered device. The DC current plates are positioned and energized to create a protective field that preemptively counteracts the interference
2Ease of operation
If sensitive AC-powered devices are placed near wall receptacles to access AC power, then electrical power is available, but the devices suffer from interference and distortion in the AC line signal
Solution Approach 1:
The DC voltage generator and DC current plates serve as an intermediary protective system that is introduced between the wall receptacle and the sensitive AC-powered device. This intermediary creates a DC electromagnetic field that shields the device from electromagnetic interference and radio frequency interference, thereby maintaining signal quality while preserving easy access to AC power
Solution Approach 2:
The patent converts the harmful electromagnetic field into a beneficial protective field by using the DC voltage generator to create a DC electromagnetic field that opposes and neutralizes the harmful AC electromagnetic fields. The same electromagnetic phenomenon that causes interference is harnessed in a controlled DC form to protect against it

AI summary
An AC voltage conditioner to be connected between a source of AC line voltage or non-linear voltage and one or more AC-powered devices (e.g., audio/video, medical and scientific equipment) to improve the performance of the devices by reducing the effects of interference and distortion often caused by an AC electromagnetic field or radio frequency interference in the vicinity of the devices. A pair of AC current conducting plates are respectively electrically connected between positive and negative output terminals of the AC line voltage source and positive and negative input terminals of each AC-powered device. The pair of AC current conducting plates are interposed between and separated from three DC current carrying plates. The DC current carrying plates are connected in electrical parallel with one another between positive and negative output terminals of a DC voltage generator. DC currents flowing through the DC current carrying plates from the DC voltage generator cause respective DC electromagnetic fields to surround the AC current carrying plates. Therefore, the AC currents flowing through the AC current carrying plates of the AC voltage conditioner will pass through the DC electromagnetic fields ahead of each AC-powered device.
