Electronic Device Power Continuity via Mobile Terminal Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display (HMD) devices experience temporary power loss when disconnected from a power supply, causing disruptions in user experience due to the delay in recognition by mobile terminals and subsequent power resumption.
Innovation Solution
A method and electronic device configuration that allows HMD devices to temporarily receive power from a mobile terminal even when disconnected from an external power supply, using a second switch and power adjustment circuit to maintain power continuity through the mobile terminal's power path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the HMD device is disconnected from the power supply, then the device can be portably used with mobile terminal, but the device experiences temporary power loss causing user experience disruption
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary power source between the external power supply and the HMD device. When the HMD device is disconnected from the external power supply, the mobile terminal acts as a mediator to provide continuous power to the HMD device, preventing power loss and maintaining operational reliability during portable use.
2Device complexity
If the HMD device waits for mobile terminal recognition before receiving power, then power management is simplified, but power delivery is delayed causing operational interruption
Solution Approach 1:
The patent implements preliminary action by having the mobile terminal prepare and supply power to the HMD device immediately upon detection of disconnection from external power supply, without waiting for full recognition and negotiation protocols. This preliminary power delivery prevents operational interruption while maintaining simplified power management through automatic detection and response.
