Rotating Slide Mobile Terminal with Curved Guide Rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slide-type mobile communication terminals have a linear opening mechanism, making it inconvenient to use multimedia services due to a fixed liquid crystal display orientation, which requires rotating the entire device for a wide-screen view and lacks stable screen orientation.
Innovation Solution
A rotating slide-type mobile communication terminal with guide rails of different curvatures and lengths on the main body and coupling bosses on the slider, allowing the slider to rotate 90°, changing the liquid crystal display's orientation laterally, and incorporating elastic members for semi-automatic opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a linear opening mechanism is used, then the structure is simple, but the liquid crystal display orientation cannot be changed for widescreen viewing
Solution Approach 1:
The guide rails are designed with curved paths instead of linear trajectories, enabling the slider to rotate 90 degrees during opening. This curved guide rail mechanism allows the liquid crystal display to change from portrait to landscape orientation, achieving widescreen viewing capability while maintaining a relatively compact structure.
Solution Approach 2:
The opening mechanism transitions from a static linear sliding structure to a dynamic rotating structure. The slider is designed to not only slide but also rotate during the opening process, dynamically changing the display orientation from portrait to landscape mode to accommodate different viewing needs.
2Adaptability or versatility
If the entire terminal is rotated for widescreen view, then the display orientation changes, but the terminal becomes unstable
Solution Approach 1:
The terminal is divided into two independent parts: a stationary main body and a movable slider containing the liquid crystal display. By segmenting the device, only the slider needs to rotate for widescreen viewing while the main body remains stable, eliminating the need to rotate the entire terminal and thus maintaining overall stability.
Solution Approach 2:
The sliding motion is enhanced by adding a rotational dimension. The slider moves not only linearly along the guide rails but also rotates around an axis, changing the display orientation from portrait to landscape without affecting the stability of the main body, effectively utilizing multi-dimensional motion.
3Adaptability or versatility
If guide rails with different curvatures and lengths are used, then the slider can rotate 90°, but the coupling mechanism becomes more complex
Solution Approach 1:
Coupling bosses are introduced as intermediary elements that connect the slider to the guide rails. These coupling bosses simplify the connection mechanism by providing standardized coupling points, reducing the complexity of directly coupling the slider to the curved guide rails while enabling the 90-degree rotation capability.

AI summary
Disclosed herein is a rotating slide-type mobile communication terminal. The rotating slide-type mobile communication terminal of the present invention includes a main body which includes a pair of guide rails having different curvatures and lengths formed at both sides in a central portion of the main body. The rotating slide-type mobile communication terminal further includes a slider which has on a front surface thereof a liquid crystal display to output various video signals, and a pair of coupling bosses on a rear surface thereof, so that, while the coupling bosses execute a sliding motion, the orientation of the slider is changed in a lateral direction of the main body. The rotating slide-type mobile communication terminal further includes a coupling means, which couples the bosses of the slider to the guide rails of the main body. Therefore, when the slider is opened, the orientation of the liquid crystal display of the slider is changed in a widescreen direction, thus allowing a user to effectively use various multimedia services, such as a TV, moving images and games.
