Image sound device having display portion that can appear/disappear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio-visual devices require separate sound and image devices, leading to exposure of screens which cannot be protected and result in reduced viewer immersion due to aspect ratio issues and limited visibility of image-related sound outputs.
Innovation Solution
An audio-visual device with a display part that can appear and disappear, featuring a lifter mechanism allowing the display to be adjusted in height and accommodated within a housing, enabling it to function as both an image and sound device with adjustable aspect ratios and protection of the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the display part is always exposed like conventional image devices, then the screen is visible for viewing, but the screen cannot be protected or hidden
Solution Approach 1:
The display part is designed to be movable between exposed and hidden positions through a lifting mechanism. The controller dynamically adjusts the display part position based on operational states, enabling the screen to be protected when not in use while remaining accessible for viewing during operation.
2Adaptability or versatility
If the screen displays images with aspect ratio 21:9 on a 16:9 screen, then more image content is shown, but black screens appear on upper and lower portions reducing viewer immersion
Solution Approach 1:
The display part can be dynamically positioned at different heights to adjust the visible display area. When displaying 21:9 images, the system lifts the display part to eliminate black screens and provide full-screen coverage, enhancing viewer immersion while maintaining aspect ratio versatility.
Solution Approach 2:
The solution adds vertical positioning as a new dimension for controlling the display area. By moving the display part vertically, the system can adjust which portions of the screen are visible, allowing full utilization of the display area for different aspect ratios without compromising immersion.
3Adaptability or versatility
If separate sound devices and image devices are manufactured, then each device can be optimized for its specific function, but the user needs to purchase and manage multiple devices
Solution Approach 1:
The patent combines sound device and image device functions into a single integrated unit. The housing contains both the speaker unit and the display part with lifting mechanism, allowing the user to have one device that performs both audio and visual functions, reducing the number of separate devices needed.
Solution Approach 2:
The integrated device is designed to perform multiple functions: it can operate as a sound device with the display hidden, as an image device with the display exposed, and as both simultaneously. This multi-functionality allows a single device to replace what would traditionally require separate sound and image devices.
4Volume of moving object
If the screen size in sound devices is small, then the device can be compact, but the content can only be viewed when the user is close to the device
Solution Approach 1:
The display part can be dynamically extended outward from the housing when needed, increasing the effective viewing distance while maintaining a compact form when retracted. This allows users to view content from a greater distance when the display is extended, while the device remains compact when the display is retracted.
