Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with high power consumption, such as graphic cards, often face instability and potential damage due to power supply limitations, especially during overclocking or when multiple graphic processing units are involved, as existing power supply architectures lack efficient integration and misconnection prevention.
Innovation Solution
A power integration module that integrates multiple power supply signals into a single, higher-capacity output while ensuring consistent characteristic parameters, using sensors and determining circuits to prevent parallel connection of power supplies with different specifications, and includes a switch unit and alert mechanism to manage power distribution safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple power supplies are connected in parallel to increase power capacity, then the power supply capability is improved, but the risk of misconnection and system instability increases
Solution Approach 1:
The determining unit checks whether the characteristic parameters of multiple power supplies are consistent before allowing them to be connected in parallel. This preliminary verification action prevents misconnection and ensures system stability before the power integration occurs, resolving the contradiction between increasing power capability and maintaining system reliability
Solution Approach 2:
The determining unit continuously monitors and compares the characteristic parameters of power supplies, providing feedback control to prevent improper parallel connection. This feedback mechanism ensures that only power supplies with consistent parameters are integrated, maintaining system reliability while enabling power scaling
2Device complexity
If power supply characteristic parameters are not verified before parallel connection, then the device complexity is reduced, but the risk of wrong connection and damage increases
Solution Approach 1:
The determining unit performs preliminary verification of power supply characteristic parameters before parallel connection is established. This advance checking action prevents wrong connection and potential damage while adding minimal complexity to the overall system
Solution Approach 2:
The determining unit acts as an intermediary between multiple power supplies and the parallel connection interface. It mediates the connection process by verifying parameter consistency, thereby preventing harmful misconnections without requiring complex control mechanisms throughout the entire system

AI summary
A power integration module includes a first input connector, a second input connector, an output connector, a switch unit, a determining unit. The first input connector and the second input connector are electrically connected to a first power supply and a second power supply of a power supply module. The output connector is electrically connected to an electrical load. The switch unit is coupled between the first input connector, the second input connector and the output connector. When the switch unit is turned on, the first input power supply and the second input power supply are integrated in parallel and outputted to the output connector to the electrical load. Moreover, an electronic device with a plurality of power integration modules is provided. Thus, the wrong connection is prevented and the condition that the power supplies of different electrical parameters are connected in parallel is avoided.
