Sliding Mobile Terminal Spring Module Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sliding-type mobile communication terminals lack ease and convenience in opening and closing operations, as users must manually slide one housing relative to another, which can be cumbersome and inefficient.
Innovation Solution
Incorporation of a spring module with a link bar, coil spring, and slider mechanism that provides a sliding force in one direction for closure and another direction for opening, allowing semi-automatic operation with minimal user effort, utilizing guide rails and guide rods for stable movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sliding-type terminal with two housings is used, then the terminal can prevent undesired operation errors by covering the keypad, but the user must manually slide one housing relative to another, which reduces ease of operation
Solution Approach 1:
The spring module enables the housing to open and close automatically through elastic force, making the system self-serving by eliminating the need for continuous manual operation. The spring stores and releases energy to perform the sliding action autonomously.
Solution Approach 2:
The spring module is pre-loaded with elastic energy that is released to automatically open or close the housing. This preliminary action stored in the spring allows the terminal to perform the sliding operation without requiring user effort at the moment of opening/closing.
2Ease of operation
If a spring module with link bar and slider mechanism is added, then semi-automatic opening and closing is achieved, but the device complexity increases
Solution Approach 1:
The spring module integrates multiple components (spring, link bar, slider, guide rails) into a unified mechanism that combines elastic force generation, motion conversion, and guidance functions. This merging reduces the number of separate components needed and simplifies the overall structure.
Solution Approach 2:
The mechanism uses dynamic elements including a rotatable link bar that changes orientation during operation, a slider that moves along guide rails, and a spring that dynamically stores and releases elastic energy. These dynamic components enable automatic motion while maintaining structural simplicity.

AI summary
A sliding-type mobile communication terminal having a first housing and a second housing adapted to allow the first housing to be opened or closed by means of a sliding movement on the first housing in a longitudinal direction of the first housing. The terminal includes a spring module adapted to provide a sliding force, along the longitudinal direction of the first housing, for allowing closing of the second housing within a predetermined range of distance, and for providing the sliding force in an opposite direction for allowing opening of the second housing beyond the predetermined range of distance. The spring module includes link bars rotatably coupled in one end onto the first housing, coil springs supported by one end of the link bar and coupled to enclose the link bar, and a slider slidably coupled to the link bar to be acted upon by an elastic force from the coil spring. The terminal uses the elasticity in coil springs to implement a semi-automatic sliding opening/closure of the second housing.
