Motor-Driven Display Device for Dynamic Area 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 or user interactions, leading to inefficient power consumption and limited user control over content presentation.
Innovation Solution
A display device equipped with a motor and controller that selectively exposes a partial or entire display area, allowing for dynamic changes in display size based on events, control signals, and content type, minimizing power consumption by defining specific content modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is always fully exposed, then the user can view content in the entire display area, but power consumption increases and space utilization decreases when the display is not being watched
Solution Approach 1:
The display device dynamically adjusts the exposed display area size based on operational state and user interaction. The motor mechanism enables the display to transition between fully exposed, partially exposed, and retracted states, optimizing the balance between visibility and power consumption according to actual usage conditions
2Area of stationary object
If the display area is always fully exposed, then the display is always visible, but space utilization is reduced when a black screen is exposed and the user does not watch the display device
Solution Approach 1:
The display adapts its exposed area dynamically based on usage context. When not in use or when a black screen is displayed, the display retracts or partially exposes, allowing the space to be utilized for other purposes or to maintain a compact form factor, thereby improving overall space utilization
3Adaptability or versatility
If a motor is added to vary the display area, then the display can selectively expose partial or entire regions, but power consumption increases due to motor operation
Solution Approach 1:
The motor operates only partially or intermittently based on actual need, transitioning the display between states only when necessary. This partial action approach minimizes motor runtime and associated power consumption while still providing the necessary display area control functionality
Solution Approach 2:
The motor performs periodic adjustments to the display area based on usage patterns, such as retracting during idle periods and extending when content needs to be displayed. This periodic operation reduces overall power consumption compared to continuous operation
4Ease of operation
If the display area is varied based on user interaction, then user control over content presentation is enhanced, but device complexity increases
Solution Approach 1:
The display device automatically adjusts its exposed area based on detected user interaction or operational state without requiring direct manual control. The system self-regulates the display visibility and size based on sensors or controller inputs, reducing the need for complex user interfaces while maintaining ease of operation

AI summary
An embodiment of the present disclosure provides a display device comprising: a communication unit for communicating with the outside; a display including a display area for outputting contents; a motor for controlling the display so that a partial area of the display area is exposed to the outside; and a controller for controlling the communication unit, the display, and the motor, wherein the controller performs control to output a first content on a first partial view in a state in which the display is the first partial view, changes the display to a second partial view when an event occurrence is received, and performs control to output a second content on the second partial view, wherein the second partial view has a display area which is exposed to the outside and is larger than that of the first partial view.
