Sliding Terminal Push Rod Rotation Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional push rods in sliding type portable terminals interrupt sliding movement due to the perpendicular direction of driving force relative to the housings' movement, causing the housings to be held in a stopped state when the rotation members approach each other.
Innovation Solution
A push rod design with support members and elastic members that provide elastic force, and rotation members rotatably coupled to the housings, allowing the rotation members to rotate and maintain driving force balance even when perpendicular to the sliding direction, ensuring continuous sliding movement by creating an unbalanced state of driving force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional push rod with rotation members is used in a sliding type portable terminal, then the terminal can be miniaturized and slimmed, but the sliding movement is interrupted when the rotation members approach each other due to perpendicular driving force direction
Solution Approach 1:
The push rod employs dynamically adjustable rotation members that can change their rotational state based on the sliding position. When the rotation members approach each other, they rotate to maintain an unbalanced driving force state, ensuring continuous sliding movement throughout the entire range of motion while preserving the compact design
Solution Approach 2:
The invention changes the directional parameters of the driving force by allowing the rotation members to alter their orientation dynamically. This parameter change enables the push rod to maintain effective driving force application even when the members approach each other, preventing movement interruption while keeping the terminal miniaturized
2Device complexity
If the direction of driving force is perpendicular to the moving direction of the housings, then the push rod structure is compact, but the driving force is not properly transmitted and the housings are held in a stopped state
Solution Approach 1:
The rotation members are designed to dynamically adjust their orientation based on the sliding position. When approaching the perpendicular position, they rotate to maintain an unbalanced driving force state, ensuring smooth sliding operation throughout the entire range of motion while preserving the compact push rod structure
