Retractable Cover Auxiliary Display for Foldable Device Voice Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in determining whether a digital assistant on a device is active and listening for voice input commands when the device is in a closed state, leading to frustration when commands are not processed.
Innovation Solution
A method is implemented to detect voice input commands and display a notification on an auxiliary display when the device is in a closed state, informing the user that their input is being detected, using a dynamically movable cover to reveal the auxiliary display during the transition from an open to a closed state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device is in a closed state to protect the display and reduce portability issues, then device protection and compactness are improved, but user feedback on command detection becomes unavailable
Solution Approach 1:
The notification system is segmented into two distinct display locations: the primary display for notifications when the device is open, and an auxiliary display on the cover for notifications when the device is closed. This segmentation allows feedback to be delivered appropriately regardless of device state, resolving the contradiction between device protection and user feedback availability.
Solution Approach 2:
The auxiliary display on the cover acts as an intermediary notification channel that becomes active when the primary display cannot provide feedback (i.e., when the device is closed). This intermediary ensures continuous user feedback capability while maintaining device protection in closed state.
2Illumination intensity
If the primary display is used for all notifications, then notification visibility is improved, but notifications cannot be displayed when the device is closed
Solution Approach 1:
The notification system is designed with multi-functionality to operate in both open and closed device states. The primary display handles notifications when the device is open, while the auxiliary display on the cover handles notifications when the device is closed, making the overall notification system universal across all device states.
Solution Approach 2:
The notification system dynamically switches between the primary display and the auxiliary display based on the device state. When the device transitions from open to closed, the notification capability dynamically shifts from the primary display to the auxiliary display, ensuring continuous adaptability.
3Loss of information
If the cover is made retractable to reveal auxiliary display, then feedback capability in closed state is improved, but device structure complexity increases
Solution Approach 1:
The auxiliary display is positioned on the cover in a different spatial dimension than the primary display. By utilizing the cover surface as a notification area, the system adds another dimension for feedback delivery without requiring complex internal mechanisms, simply leveraging the existing cover structure.
