Solution Overview
Problem
Existing sliding opening and closing devices in portable terminals, such as those using torsion springs, face issues with insufficient elasticity power and early fatigue due to wide motion, leading to reduced device lifespan and operational inefficiency.
Innovation Solution
A sliding opening and closing device that incorporates a power transformation member to enhance the elasticity power of the slide plate by converting it into pushing force, using components like rotating arms, moving blocks, and links to manage the movement and maintain optimal positions, thereby increasing the device's operational lifespan and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a torsion spring is used as elastic means in a sliding-type terminal, then the sub body can be opened and closed, but the elasticity power is insufficient and the spring undergoes wide motion causing early fatigue
Solution Approach 1:
A power transformation member is introduced as an intermediary between the elastic part and the slide plate. This mediator converts the elastic force into effective pushing force at optimal positions, resolving the contradiction by enabling the elastic part to exert sufficient force without undergoing wide motion that causes fatigue
Solution Approach 2:
The invention changes the parameters of force application by using a power transformation member to convert elastic force into pushing force at specific positions. This parameter transformation allows the elastic part to maintain high force output with reduced motion range, extending its lifespan
2Ease of operation
If the slide plate is manually opened and closed, then the operation is simple, but user convenience is reduced compared to automatic operation
Solution Approach 1:
The slide plate is designed to perform automatic opening and closing operations through the elastic part and power transformation member. The system serves itself by converting elastic potential energy into kinetic energy to move the slide plate, eliminating the need for manual operation while maintaining structural efficiency
3Adaptability or versatility
If the display device is fixed in orientation, then the structure is simple, but the ability to display horizontally long images is limited
Solution Approach 1:
The display device is made dynamic by enabling rotation relative to the slide plate. This dynamic configuration allows the display to adapt between different orientations (horizontal and vertical), providing versatility for displaying various image formats while maintaining a relatively simple mounting structure through rotational joints

AI summary
Disclosed are a sliding opening and closing device and a portable terminal having the same. According to the first embodiment of the present invention, a slide plate is linked to a main plate to be slidable in one direction. Also, the main plate supports an elastic part so as to generate an elasticity power in one direction. A power transformation member receives the elasticity power of the elastic member, and transmits the elasticity power to the slide plate in the direction of the opening or the closing according to the position of the slide plate.
