Display Power Allocator for High-Output USB Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with limited power output capabilities, such as those using a single USB port, often fail to provide sufficient power to peripheral devices like laptops, which require higher operational power, necessitating additional power sources.
Innovation Solution
Incorporating multiple power inputs and a power allocator within the display device to combine and distribute power, allowing the display device to output a combined power greater than its individual limits via a single USB port, thereby satisfying the power requirements of peripheral devices without additional power cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a display device uses a single USB port with limited power output capability, then the device complexity is reduced and ease of manufacture is improved, but the power output capability becomes insufficient for peripheral devices like laptops
Solution Approach 1:
The patent combines multiple power inputs (first power input and second power input) into a unified power output through a power allocator. The power allocator merges the power from different sources and delivers the combined power through a single USB port, enabling the display device to provide sufficient power to peripheral devices while maintaining a simple single-cable connection interface.
2Ease of operation
If a display device uses a single USB port, then the ease of operation is improved and cable management is simplified, but the power output is insufficient to satisfy the operational power requirements of peripheral devices
Solution Approach 1:
The USB port in the display device is designed to perform multiple functions: it serves as both a data communication interface and a high-capacity power delivery interface. The power allocator enables the USB port to deliver combined power from multiple sources, making it a universal interface that handles both data and power needs of peripheral devices through a single connection.
3Power
If additional power sources are connected directly to peripheral devices, then the power requirement is satisfied, but the device complexity increases and additional cables are required
Solution Approach 1:
The display device acts as an intermediary between multiple power sources and the peripheral device. Instead of connecting power sources directly to the peripheral device (which would require additional cables and increase complexity), the power sources are connected to the display device, which then mediates the power delivery through its USB port to the peripheral device.

AI summary
In an example, a display device with power inputs includes a first power input to receive a first amount of input power, a second power input to receive a second amount of input power, a power allocator to combine at least a portion of the first amount of power with at least a portion of the second amount of power to form a combined output power, and a universal serial bus (USB) port to output at least a portion of the combined output power to a peripheral device.
