Folding Mobile Terminal Dual-Axis Hinge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Folding mobile terminals have limited flexibility in expansion, affecting user experience due to restricted rotation directions between connected parts.
Innovation Solution
A folding mobile terminal design featuring a connecting clamp with intersecting or non-coplanar axes, allowing the second housing to rotate relative to the first housing in multiple directions, enhancing expansion flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two parts are connected via rotation with a single rotation direction, then the structure is simple, but the folding flexibility is limited
Solution Approach 1:
The patent introduces a second rotation direction perpendicular to the first rotation direction, transforming a single-degree-of-freedom connection into a two-degree-of-freedom connection. This dimensional change enables the folding mobile terminal to achieve multiple expanded states and improved folding flexibility without excessively complicating the overall structure.
Solution Approach 2:
The connection structure is designed to be dynamically adjustable, allowing rotation in multiple directions depending on user needs. The first and second rotation directions enable the terminal to transition between different configurations (folded, partially expanded, fully expanded, and various intermediate states), making the structure adaptable rather than fixed.
2Area of moving object
If the overall size of the mobile terminal is determined, then portability is improved, but the screen-to-body ratio cannot be increased
Solution Approach 1:
The mobile terminal employs a dynamic folding mechanism that allows the device to transform between a compact folded state for portability and an expanded state with a larger effective screen area. The connection structure enabling rotation in multiple directions facilitates smooth transitions between these states, allowing users to carry the device compactly while accessing a larger display when needed.
