Motorized Retractable Display Exposure for Event-Driven Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices expose all regions of the display area regardless of user interaction, leading to inefficient use of space when not in use and increased power consumption due to unnecessary motor operation.
Innovation Solution
A display device with a motor-controlled mechanism to selectively expose the entirety or part of the display area based on detected events, such as Bluetooth signals from user terminals or IoT devices, allowing for interactive control of display modes and content output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If the display area is always exposed, then the display is always visible to users, but power consumption increases and space utilization is inefficient when no content is being displayed
Solution Approach 1:
The display device dynamically adjusts the exposure state of the display area by moving the display between retracted and exposed positions based on operational modes. The controller automatically changes the display position according to detected events (e.g., terminal connection, IoT device operation), transforming the static display structure into a dynamic one that adapts to usage conditions, thereby reducing power consumption while maintaining visibility when needed
2Use of energy by stationary object
If the display is moved to expose only part of the display area, then power consumption is reduced, but the capability to display content in the entirety of the display area is limited
Solution Approach 1:
The display structure is designed to be movable between multiple positions (retracted, partially exposed, fully exposed) controlled by the controller. This dynamic positioning capability allows the display to adapt to different operational requirements - exposing only necessary portions when power saving is prioritized, or exposing the entire display area when content versatility is needed, thus resolving the contradiction between power consumption and display flexibility
3Adaptability or versatility
If a motor is added to control display movement, then selective exposure capability is achieved, but device complexity increases
Solution Approach 1:
The system implements self-service control where the controller automatically detects events (terminal connection, IoT device operations) and autonomously determines the appropriate display exposure mode without requiring manual user intervention. The motor is controlled automatically based on detected events, reducing the need for complex user interface mechanisms while maintaining adaptive display exposure capability

AI summary
According to one embodiment, a display device includes: a communication unit which communicates with an external entity; a display including a display area in which a content is output; a motor which controls the display to expose a part of the display area to the outside; and a control unit. When an event is sensed in a state where the display is in a first mode, the control unit changes the display from the first mode to a second mode; when the event is sensed in a state where the display is in the second mode, the control unit changes the display from the second mode to a third mode; in the first mode, the display area is not exposed to the outside; in the second mode, the display area is partially exposed to the outside; and in the third mode, the display area is fully exposed to the outside.
