Sliding-Tilt Unit for Mobile Device Video Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile devices with sliding and tilt mechanisms face difficulties in user operation and multimedia viewing, especially when placed on a surface, due to the parallel alignment of components which hinders video viewing and operation accessibility.
Innovation Solution
A sliding-tilt unit that couples two bodies of a mobile device, allowing the second body to tilt and slide, featuring elastic members and stoppers to facilitate movement between overlapping and tilted positions, enhancing usability and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the second body is slid linearly with respect to the first body in parallel alignment, then the device structure is simple, but it is difficult for the user to watch video information and manipulate operation units when the device is placed on a table
Solution Approach 1:
The patent applies the dynamics principle by enabling the second body to tilt at a predetermined angle with respect to the first body through a tilting hinge part, transforming the static parallel alignment into a dynamic adjustable configuration. This allows the device to adapt its viewing angle when placed on a table, improving usability for video viewing and operation while maintaining structural simplicity through a controlled single-degree-of-freedom tilting mechanism rather than complex multi-axis adjustments
2Ease of operation
If the second body is tilted with respect to the first body, then video viewing and operation accessibility are improved, but the device structure becomes more complex
Solution Approach 1:
The patent merges the sliding and tilting functions into a single integrated sliding-tilt unit where the second body can perform both linear sliding and angular tilting relative to the first body. This combination eliminates the need for separate sliding mechanism and tilting mechanism, reducing overall structural complexity while providing both sliding and tilting capabilities for improved video viewing and operation accessibility
Solution Approach 2:
The tilting hinge part serves multiple functions: it enables the second body to tilt at a predetermined angle for improved viewing, allows the device to adapt to different usage scenarios (handheld or tabletop), and works in conjunction with the sliding mechanism to provide versatile positioning. This multi-functionality reduces the need for additional dedicated components
3Ease of operation
If elastic members are added to facilitate tilting movement, then the tilting function is improved, but the device structure becomes more complex
Solution Approach 1:
The elastic member is configured to automatically facilitate the tilting movement of the second body without requiring additional actuators or complex control systems. The elastic member stores and releases mechanical energy to assist the tilting action, making the system self-servicing for the tilting function while adding only a single passive component to the structure
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 solution improves the usability and portability of mobile devices by allowing the second body to tilt, enhancing multimedia viewing and operation accessibility, even when the device is placed on a surface, while maintaining a compact form.
Implementation Method 1
a first elastic member exerting a first elastic force to bias the second body away from the first body
Implementation Method 2
a second elastic member elastically connecting the first and second bodies, the second elastic member exerting a second elastic force that switches a direction of the second elastic force from a direction opposing sliding of the second body to a direction promoting sliding thereof

AI summary
A mobile device including a first body and a second body slidably and tiltably coupled. The second body can be arranged to a first location, at which the second body overlaps the first body, and a second location, at which the second body is tilted with respect to the first body after having been fully slid from the first location. Accordingly, the mobile device may improve portability and convenience in use.
