Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power adapters are used to convert AC power into DC for electronic devices, then DC power can be obtained, but the system becomes cumbersome and energy loss increases
Solution Approach 1:
The patent extracts the power conversion function from the wall socket itself, embedding AC-to-DC conversion capabilities directly into the building's power distribution infrastructure. This eliminates the need for separate external adapters at each device, as the conversion capability is built into the power source infrastructure.
Solution Approach 2:
The patent creates a universal power distribution system where wall sockets can provide multiple power types (AC and DC) through a single interface. The smart power adapter can deliver AC power for traditional devices or convert to DC power for electronic devices, making one socket serve multiple functions and eliminating the need for different adapters for different device types.
2Adaptability or versatility
If multiple power adapters are carried for different electronic devices, then compatibility is achieved, but portability and convenience deteriorate
Solution Approach 1:
The patent implements a universal power delivery system where a single smart power adapter can provide both AC and DC power outputs, accommodating both traditional AC-powered devices and modern DC-powered electronic devices. This multi-functionality eliminates the need for users to carry multiple device-specific adapters, significantly improving portability while maintaining broad device compatibility.
3Use of energy by moving object
If AC power is converted to DC power using traditional adapters, then DC power is obtained, but energy loss increases due to sub-conversion efficiency
Solution Approach 1:
The patent performs power conversion at the source (the wall socket) before power distribution, rather than at the point of use. By converting AC to DC at the building's power distribution infrastructure, the system eliminates repeated conversion losses that would occur if each device performed its own conversion, significantly improving overall energy efficiency.
Data Source
AI summary
Existing AC power distribution infrastructure in a building is leveraged for the DC power distribution, where one or more DC powers are delivered over an existing power distribution circuit and existing AC power sockets. A DC power attachment is coupled to an existing AC power socket to provide various DC voltages, including a high DC voltage for high power DC devices and a low DC voltage for low power DC devices. Transition from the AC centric environment to a DC environment is thus simplified thereby improving energy usage efficiency and making DC power readily available.
