Retractable Display Mechanism for Sound Device Aspect Ratio Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sound and image devices are separate units, leading to issues such as unprotected screens, limited aspect ratio compatibility, and reduced viewer immersion due to black borders when displaying certain image formats, and the inability to conveniently output images related to sounds.
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 exposed or concealed, enabling dual functionality as both a sound and image device, and accommodating various aspect ratios without black borders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display part is always exposed, then the user can view images and information at any time, but the screen cannot be protected or hidden
Solution Approach 1:
The display part is designed to be dynamically movable between an exposed state for viewing and a retracted state for protection. The lifter mechanism enables the display to automatically protrude or retract based on operational needs, transforming a static protective cover into a dynamic system that adapts to user requirements.
2Adaptability or versatility
If the display part is fixed at one height, then the structure is simple, but the device cannot accommodate different aspect ratios without black borders
Solution Approach 1:
The lifter mechanism provides dynamic height adjustment of the display part, enabling it to achieve multiple positional states. This dynamic positioning capability allows the display to adapt to different aspect ratios (such as 16:9 and 21:9) by adjusting its height, thereby eliminating black borders while maintaining a relatively simple overall structure.
3Productivity
If the display part is always exposed, then images can be displayed, but the screen cannot be protected when not in use
Solution Approach 1:
The display part operates in periodic cycles between being exposed for display functionality and retracted for protection. The lifter mechanism automatically controls this periodic transition, ensuring the display is only exposed when needed for viewing or information output, thereby minimizing exposure time and reducing the risk of screen damage.
4Volume of moving object
If a small screen is provided in the sound device, then the device size is compact, but the contents can only be viewed when the user is close to the device
Solution Approach 1:
The display part utilizes the lifter mechanism to dynamically adjust its protrusion height from the housing. When viewing is needed, the display protrudes to a greater extent, increasing its effective size and allowing users to view contents from a greater distance. When not in use, it retracts to maintain compactness, thus providing both compactness and viewing flexibility.

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 the display to be protected when not in use, adjustable to fit different aspect ratios, and functions as both a sound and image device, improving immersion and convenience.
Implementation Method 1
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
