Rotation Connection Component for Foldable Mobile Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen mobile terminals face portability issues due to their increased size, which affects user handling and appearance performance, as existing foldable designs often expose rotation shafts that hinder usability and aesthetics.
Innovation Solution
A rotation connection component comprising a first base, a second base, and a connection clamp that allows the second base to rotate relative to the first base by a preset angle, enabling the foldable mobile terminal to switch between unfolded and folded states without exposing the rotation shaft, thereby improving portability and appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-screen mobile terminal is designed to increase screen area, then display performance is improved, but overall size increases and portability deteriorates
Solution Approach 1:
The mobile terminal is divided into two separable bases (first base and second base) that can be folded relative to each other. The connection clamp mechanism allows the terminal to be segmented into foldable portions, enabling compact folding while maintaining large screen area when unfolded.
Solution Approach 2:
The connection clamp is designed to slide into and nest within the first base when folded, creating a compact configuration. The nested structure allows the terminal to reduce its overall size significantly when folded, improving portability while maintaining full screen area when unfolded.
2Device complexity
If a traditional rotation shaft connection is used for foldable terminals, then structural simplicity is maintained, but the rotation shaft is exposed and appearance performance deteriorates
Solution Approach 1:
The connection clamp nests into the first base when folded, concealing the connection mechanism and eliminating exposed rotation shafts. This nested design maintains structural functionality while significantly improving appearance performance by creating a sleek, hidden connection interface.
Solution Approach 2:
The traditional exposed rotation shaft is extracted and replaced with a concealed connection clamp mechanism that slides into the base. This extraction of the visible rotation shaft element resolves the appearance issue while maintaining the rotational folding functionality through the clamp's sliding mechanism.
3Ease of manufacture
If the connection clamp is made detachable for ease of assembly, then manufacturing efficiency is improved, but connection reliability may deteriorate
Solution Approach 1:
The connection clamp serves as an intermediary component between the first and second bases, providing a detachable yet reliable connection. The clamp's sliding and locking mechanism ensures secure attachment during use while allowing easy detachment for assembly and maintenance, balancing manufacturing efficiency with connection reliability.

AI summary
A rotation connection component includes: a first base, a second base, and a connection clamp. The second base is rotationally connected to the first base through the connection clamp, the connection clamp is slidably connected to the first base, the rotation connection component has an unfolded state and a folded state. In the folded state, the connection clamp slides into the first base. In the unfolded state, at least a portion of the connection clamp slides from the first base, and the second base rotates by a preset angle relative to the first base.
