Voice-Controlled Rollable Display State Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rollable display devices either rely on mechanical operations for switching states, which lacks intelligence, or require user contact through fingerprint unlocking, causing inconvenience, especially for larger or hard-to-reach devices, leading to poor user experience and space utilization.
Innovation Solution
A display device with a rollable screen that incorporates a voice acquisition unit, identification control unit, drive control unit, and display control unit, allowing for intelligent voice-controlled switching between rolled and display states, using voice commands to perform rolling and display operations, and utilizing voiceprint recognition for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If mechanical operations are used to switch display states, then the device structure is simple, but the intelligence and user experience are poor
Solution Approach 1:
The patent replaces mechanical operation-based state switching with a voice-controlled system. The voice acquisition unit captures user commands, the identification control unit recognizes and processes them, and the drive control unit executes the corresponding rolling or display state changes, eliminating the need for physical contact or mechanical switches while enhancing intelligence.
Solution Approach 2:
The patent introduces voice commands as an intermediary between the user and the display device state switching. Instead of direct mechanical operation or fingerprint contact, users speak commands that are transmitted through the voice acquisition and identification units to trigger state changes, providing a non-contact intelligent interface.
2Ease of operation
If fingerprint unlocking is used to control rollable screens, then authentication is provided, but user contact is required causing inconvenience for large or hard-to-reach devices
Solution Approach 1:
The patent replaces fingerprint-based contact authentication with voice-based non-contact control. The voice acquisition unit captures commands from a distance, eliminating the need for physical contact with the device, which is particularly beneficial for large or hard-to-reach display devices while maintaining operational reliability through voice recognition.
3Ease of operation
If voice commands are used to control the display device, then user experience and convenience are improved, but the device complexity increases
Solution Approach 1:
The patent segments the control system into distinct functional modules: the voice acquisition unit for capturing commands, the identification control unit for recognizing and interpreting them, and the drive control unit for executing state changes. This modular segmentation manages complexity by assigning specific functions to separate components, making the overall system more maintainable and scalable.
