Motor-Driven Display with Dynamic Exposure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices do not have the capability to vary the size of the exposed display area based on received information, leading to inefficient use of space and increased power consumption due to constant exposure of all display regions.
Innovation Solution
A display device equipped with a motor that controls the exposure of partial or entire display areas, along with a controller that changes the display mode based on user utterances and control signals, allowing for selective exposure and minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If all regions of the display are always exposed, then the display area is maximally available, but space utilization is inefficient and power consumption increases
Solution Approach 1:
The display device dynamically adjusts the exposed display area based on operational mode and user interaction. The motor mechanism enables the display to transition between fully exposed, partially exposed, and retracted states, optimizing the balance between display area availability and power consumption according to actual usage requirements
2Adaptability or versatility
If a motor is added to control display exposure, then space utilization and power consumption are optimized, but device complexity increases
Solution Approach 1:
The motor mechanism serves multiple functions: it controls the display exposure level, enables different operational modes (broadcast viewing, partial display, fully retracted), and responds to various input types (remote control, voice commands). This multi-functionality justifies the added complexity by providing versatile display control capabilities
3Adaptability or versatility
If the display moves between different exposure positions, then functionality is enhanced, but reliability requirements increase
Solution Approach 1:
The system includes protective measures for the motor and display mechanism, such as error handling protocols, operational limits, and safety features that prevent damage during movement between positions. These preemptive reliability measures ensure consistent operation across multiple positioning cycles

AI summary
In one embodiment of the present invention, provided is a display device characterized by comprising: a microphone for receiving a user's voice; a communication unit for communicating with the outside; a display including a display area for outputting content; a motor for controlling the display to expose a portion of the display area to the outside; and a control unit for controlling the communication unit, the display, and the motor. The control unit: changes the display to one of a hidden view, a first partial view, a second partial view, or a full view; recognizes the received user's voice; changes the display to the first partial view or the second partial view and outputs the result of the voice recognition to the first partial view or the second partial view when the voice recognition is successful; and changes the display to the second partial view and outputs a virtual keyboard to the second partial view when the voice recognition fails, wherein the hidden view is a state in which the display area is not exposed to the outside, the first partial view is a state in which a first area of the display area is exposed to the outside, the second partial view is a state in which a second area of the display area is exposed to the outside, and the full view is a state in which the display area is maximally exposed to the outside.
