Rollable Display Control for Voice Results in Zero View Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in quickly and accurately providing results to users after receiving voice commands, especially when in zero view mode, as it takes time to draw out the display, delaying the immediate delivery of results.
Innovation Solution
The display device incorporates a rotatable roller mechanism that adjusts the display's length, allowing the controller to manage the display mode and provide voice command results differently based on the drawn-out length, enabling immediate and accurate results without additional driving, by outputting audio or displaying results on the screen depending on the mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display is entirely drawn into the housing (zero view mode), then the device structure is more compact, but the time required to provide voice command results increases
Solution Approach 1:
The display transitions from a static fully-retracted state to a dynamically adjustable state, partially extending when voice commands are detected. This dynamic adaptation allows the system to maintain compactness during normal operation while quickly providing visual feedback for voice commands by adjusting the display extension level based on command type and context.
Solution Approach 2:
The display is pre-positioned in a partially extended state or可以快速 extend to a predetermined level when voice command detection is triggered, eliminating the need to wait for full extension. This preliminary positioning enables immediate visual feedback for voice commands without requiring the display to fully extend first.
2Loss of time
If the display is entirely drawn out from the housing (full view mode), then the voice command results can be displayed immediately, but the device loses its compact structure
Solution Approach 1:
Instead of extending the entire display for all operations, only the necessary portion of the display is extended based on the specific operation type. For voice commands, the display extends to a level sufficient for displaying command results, while maintaining a more compact state for other functions, thus optimizing both responsiveness and portability.
Solution Approach 2:
The display extension level is dynamically adjusted based on the detected operation type. When a voice command is detected, the display automatically extends to an appropriate level for displaying results, and retracts when not needed, providing immediate visual feedback without permanently maintaining a non-compact state.
3Use of energy by moving object
If the display is partially drawn out (partial view mode), then power consumption is reduced, but the visibility of voice command results is limited
Solution Approach 1:
The display dynamically adjusts its extension level based on the type of voice command and the amount of information to be displayed. For simple voice commands with brief results, the display remains partially extended to conserve power. For complex commands requiring detailed information display, the display automatically extends to a greater level, ensuring adequate visibility while minimizing unnecessary power consumption.
Solution Approach 2:
The system changes the display extension parameter based on the voice command type and information density. By adjusting this physical parameter dynamically, the system optimizes the balance between power consumption and information visibility, extending only as much as necessary to display the required information clearly.
