Unifying Electrical Interface Platform for AC DC Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The non-universality of electrical outlet standards across countries and regions leads to inefficiencies in power distribution, requiring frequent conversions between AC and DC, resulting in energy loss and increased costs, while also making consumers vulnerable to power outages due to reliance on a single AC grid.
Innovation Solution
The Unifying Electrical Interface (UEI) platform provides a unified connection system that allows for a wide range of AC and DC voltages, enabling direct use of DC power from renewable sources, reducing the need for continuous AC conversion and allowing for easy swapping of outlets and switches without tools, thereby promoting energy conservation and independence from the AC grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple outlet standards are used across countries and regions, then local power distribution can be optimized, but conversion between AC and DC is required frequently resulting in energy loss
Solution Approach 1:
The patent implements a universal base unit with multiple voltage terminals (L1, L2, N, G) that can accommodate different outlet standards (NEMA 5-15, IEC 60320, etc.) through interchangeable plug adapters. The system provides both AC and DC output capabilities from a single base unit, eliminating the need for multiple dedicated outlets and reducing frequent conversions between different power types.
Solution Approach 2:
The patent introduces a DC power distribution network as an intermediary layer between the AC grid and DC-powered devices. The base unit converts AC to DC once at the base, then distributes DC power through dedicated terminals, eliminating repeated AC-DC conversions that would occur with traditional outlets. This intermediary DC network reduces cumulative energy loss from multiple conversion cycles.
2Device complexity
If a single AC grid is relied upon for power supply, then power distribution is simplified, but consumers become vulnerable to power outages and grid disruptions
Solution Approach 1:
The patent segments the power distribution system into independent zones by providing separate AC and DC output terminals on the base unit. This allows different circuits or devices to be powered from different sources (AC grid or DC storage), creating redundancy. If one power source fails, the other can continue to supply power to critical loads, enhancing system reliability without requiring complete system redesign.
Solution Approach 2:
The patent enables dynamic switching between different power parameters (AC voltage, DC voltage from storage) based on grid availability. The base unit can operate in grid-tied mode during normal conditions and switch to off-grid DC power mode during outages, maintaining power supply continuity. This parameter switching capability provides resilience while maintaining operational simplicity.
3Ease of operation
If AC to DC conversion is performed continuously to power DC equipment, then all DC needs are met, but energy efficiency decreases due to conversion losses
Solution Approach 1:
The patent performs AC to DC conversion in advance at the base unit during periods when power demand is low or grid power is available, storing energy in DC-capable storage elements. This preliminary conversion allows DC equipment to operate directly from stored DC power without requiring continuous real-time conversion, reducing cumulative conversion losses while maintaining the ability to power all DC equipment as needed.
Solution Approach 2:
The patent establishes a continuous DC power distribution pathway from the base unit through dedicated DC terminals to DC equipment. By maintaining this continuous DC connection rather than converting AC to DC only when needed, the system eliminates repeated conversion cycles and their associated energy losses, while still providing complete DC equipment support.
4Ease of manufacture
If traditional outlets and switches are used, then installation follows conventional standards, but replacing and upgrading requires professional services and tools
Solution Approach 1:
The patent implements a dynamic, modular outlet system where the base unit remains permanently installed but the faceplate and plug adapters can be easily swapped by consumers without tools. This dynamic design maintains standardized installation at the base level while enabling user-friendly updates and replacements at the interface level, combining manufacturing standardization with ease of repair.
Solution Approach 2:
The patent separates the replacement function into a different dimension by making the faceplate and plug adapters interchangeable components that can be changed independently of the base unit installation. This dimensional separation allows consumers to upgrade outlets or change plug types without requiring professional electricians or tools, while still maintaining standardized base installations.

AI summary
The disclosed Unifying Electrical Interface presents a versatile connectivity platform having the merging capabilities permitting more than a singular voltage, level or type to be made available from an electrical outlet. When wired fully, the choice of AC and/or DC made available to the consumer is broadened. Direct Current (DC) provided via the UEI would originate from a locally based DC source access point obviating the need to use wall chargers or power supplies that wastefully consume energy even when in standby mode. By this approach, the UEI based system extends an avenue for renewable energy technology to be made readily available in a building; while offering a synergistic advantage for the end user, the energy provider and the environment by reducing energy waste. That power conservation and accessibility will result in greater choice and savings for the consumer and will reduce the need for excess production from electric providers.
