Electronic Device Dual-Interface Power Switching for Host Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as AR glasses and AR helmets, can only be powered by a host device when coupled with it, leading to a shortened battery life due to the host device's inability to be charged through the occupied interface.
Innovation Solution
The electronic device is equipped with two interfaces and a control module that switches the power-supply path based on the type of connected device, allowing power from a host or a power-supply device to be utilized, and enables data transmission and audio output through separate interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device is coupled with the host device through a single interface, then data transmission and power supply are enabled, but the host device cannot be charged and the electronic device's battery life is shortened
Solution Approach 1:
The patent divides the interface system into two separate interfaces: a first interface dedicated to data transmission and a second interface dedicated to power supply. This segmentation allows the electronic device to simultaneously connect to the host device for data and to a power supply device for charging, resolving the contradiction by eliminating interface conflict and extending battery life.
2Loss of information
If the single interface is used for data transmission with the host device, then communication is established, but the interface cannot be used for charging the host device
Solution Approach 1:
The patent segments interface functions by assigning the first interface exclusively to data transmission with the host device and the second interface to power supply operations. This enables the host device to charge while data transmission continues uninterrupted, enhancing interface adaptability without compromising communication.
Solution Approach 2:
The electronic device achieves multi-functionality by equipping itself with two interfaces that can operate independently and simultaneously. The first interface handles data communication while the second interface manages power supply, allowing the device to perform multiple functions through a unified dual-interface system.
3Device complexity
If both the host device and electronic device are powered by the host device's battery, then power supply is simplified, but the electronic device's battery life is reduced
Solution Approach 1:
The patent segments the power supply architecture by introducing a dedicated second interface for power input, separating the power supply function from the data transmission function. This allows independent power management where the electronic device can be charged separately while maintaining simplified power distribution through the host device connection.
Solution Approach 2:
The patent introduces a power supply device as an intermediary component that connects to the electronic device through the second interface. This intermediary provides dedicated charging capability, allowing the electronic device to extend its battery life without complicating the overall power supply system architecture.
