Image sound device having display portion that can appear/disappear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sound and image devices are separate entities, leading to issues such as unprotected screens and limited immersion due to aspect ratio limitations, and the inability to seamlessly integrate sound output with image display.
Innovation Solution
An image sound device with a display part that can appear and disappear, featuring a housing with a lifter mechanism allowing the display to be adjusted in height and positioned at multiple heights, enabling it to function as both a sound and image device while protecting the screen when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display part is always exposed like conventional image devices, then the screen can be used for displaying images, but the screen cannot be protected or hidden
Solution Approach 1:
The display part is made movable between exposed and retracted positions through a lifter mechanism. The display can dynamically change its position based on usage requirements, being exposed when image display is needed and retracted when protection is required, thus resolving the contradiction between screen protection and display functionality.
2Ease of operation
If the display part is fixed at one height, then the structure is simple, but the user cannot adjust the display position for different viewing needs
Solution Approach 1:
The lifter mechanism enables the display part to move vertically between multiple predetermined heights. This dynamic positioning capability allows users to adjust the display height according to different viewing needs while maintaining a relatively compact structure through the use of linkages and rack-gear mechanisms.
3Reliability
If the display part is retracted completely into the housing, then the screen is protected, but the display cannot be viewed
Solution Approach 1:
The display part can be positioned at multiple heights including a partially exposed position. When complete retraction is not needed but full exposure is not required, the display can be maintained at an intermediate height, allowing both screen protection and partial visibility. The motor controller enables precise positioning at different heights based on operational requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides enhanced user experience by allowing adjustable display height, eliminating black borders during aspect ratio changes, and serving as both a decorative furniture and a multifunctional entertainment device.
Implementation Method 1
The driver may include a first rack gear rotatably connected to the another end of the first link; a second rack gear provided parallel to the first rack gear and rotatably connected to the another end of the second link; a pinion provided between the first rack gear and the second rack gear and configured to move the first rack gear and the second rack gear in directions opposite to each other; and a motor configured to rotate the pinion.
