Motorized Variable-View Display for Content-Driven Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices expose all regions of the display area regardless of usage, wasting space when not in use and consuming unnecessary power.
Innovation Solution
A display device equipped with a motor that selectively exposes a partial or entire region of the display area based on metadata, content type, and user interaction, minimizing power consumption by controlling the display area's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display area is always fully exposed, then the user can view content without restriction, but space is wasted when the display device is not in use
Solution Approach 1:
The display area is made dynamically adjustable through a motor-driven cover mechanism that can change the exposed area between full view, partial view, and zero view states based on usage conditions, transforming a static display system into a dynamic one that adapts to different operational scenarios
Solution Approach 2:
The cover structure is designed to nest within or around the display assembly, allowing the cover to slide or rotate into a compact position when not in use, effectively hiding the display protection mechanism while maintaining full display access when needed
2Productivity
If the display area is always fully exposed, then the display is always ready for use, but power is consumed unnecessarily when no content is being viewed
Solution Approach 1:
The display alternates between fully exposed state and retracted state in periodic cycles based on detected usage patterns, remaining fully exposed during active content viewing and retracting during idle periods, creating a rhythm of exposure that balances readiness with energy conservation
Solution Approach 2:
The system uses sensors and controllers to automatically detect whether content is being viewed and autonomously adjusts the display exposure state without user intervention, making the display self-regulate its own power consumption based on actual usage conditions
3Adaptability or versatility
If a motor is added to control the display area, then the display area size can be adjusted dynamically, but device complexity increases
Solution Approach 1:
The patent replaces complex multi-component mechanical adjustment mechanisms with a simplified motor-driven single-axis rotation or linear translation system that achieves the same display area adjustment functionality with fewer parts and lower mechanical complexity
Solution Approach 2:
The motor-driven cover mechanism serves multiple functions simultaneously: it protects the display when retracted, adjusts the visible display area to various positions, and can be integrated with sensors to enable automatic power management, consolidating multiple features into a single integrated system

AI summary
One embodiment of the present invention provides a display device, comprising: a communication unit that receives content from the outside; a display including a display area for outputting the content; a motor that controls the display to expose a portion of the display area to the outside; and a control unit that controls the communication unit, the display, and the motor, wherein the control unit parses metadata of the content, converts the display to one of a zero view, a first partial view, and a full view at a first point of view on the basis of the metadata, and outputs the content to a converted display area, wherein the zero view is a state in which the display area is minimally exposed to the outside, the first partial view is a state in which the first 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.
