Motorized TV Screen Exposure Using Audio Metadata Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing TVs have a fixed screen size exposure, leading to inefficient space utilization when not in use and high power consumption due to unnecessary motor operation.
Innovation Solution
A system that allows selective partial or full screen exposure using a motor, controlled by metadata and user preferences, minimizing power consumption by optimizing motor usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen is always fully exposed, then the display area is maximized, but space utilization is reduced when the TV is not in use
Solution Approach 1:
The patent implements a motor-driven mechanism that dynamically adjusts the screen exposure between fully exposed, partially exposed, and retracted states. The screen transitions from a static fixed position to a dynamic adjustable position, allowing the TV to adapt between maximizing display area during use and minimizing space occupation when not in use.
2Adaptability or versatility
If the motor operates frequently to adjust screen exposure, then space utilization is improved, but power consumption increases
Solution Approach 1:
The system detects audio content metadata in advance and proactively adjusts the screen exposure before video content needs to be displayed. By predicting when full screen exposure will be needed based on audio metadata analysis, the motor operates only when necessary rather than continuously adjusting, thereby reducing power consumption while maintaining adaptability.
3Use of energy by stationary object
If the screen is partially exposed to save power, then power consumption is reduced, but the display area is reduced
Solution Approach 1:
The system dynamically adjusts screen exposure based on real-time content analysis. When audio content is detected without corresponding video content, the screen remains partially exposed to save power. When video content is detected that matches the audio metadata, the screen automatically transitions to full exposure to provide the complete display area needed for the video content.
4Adaptability or versatility
If the motor is added to enable screen adjustment, then adaptability is improved, but device complexity increases
Solution Approach 1:
The motor mechanism serves multiple functions: it enables the screen to transition between fully exposed state for video content, partially exposed state for audio content or power saving, and retracted state for minimal space occupation. This single multi-functional mechanism provides adaptability for different content types and usage scenarios without requiring separate systems for each function.

AI summary
According to an embodiment of the present invention, a method for controlling a TV having a screen, the exposure size of which is changed by a motor, comprises the steps of: outputting an audio content in a state where only a part of the screen is exposed or the screen is not exposed; detecting metadata related to the audio content; when at least one video content corresponding to the detected metadata can be provided at a current time, controlling the motor to fully expose the screen and outputting a first video content; and when at least one video content corresponding to the detected metadata can be provided after a current time, continuing to output the audio content and establishing a reservation for a second video content.
