Foldable Hinge Mechanism With Floating Plate for Lightweight Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable mechanisms for terminals require a large number of parts, leading to complex structures that hinder lightweight design.
Innovation Solution
A foldable mechanism with a simplified structure that utilizes a connection assembly comprising a base, floating plate, and secondary swing arms, allowing the floating plate to float or sink relative to the base through sliding and rotating connections without the need for additional structural members like springs, thereby simplifying the overall design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional foldable mechanisms use multiple structural members (springs, connectors) to achieve folding and unfolding, then the folding function is reliable, but the structure becomes complex and weight increases
Solution Approach 1:
The patent combines the floating plate and secondary swing arm into an integrated structure, eliminating the need for separate spring connectors. The floating plate directly serves as the secondary swing arm, merging multiple components into one unified element that performs both floating and swinging functions simultaneously.
Solution Approach 2:
The floating plate is designed to perform multiple functions: it acts as both a floating element that absorbs display pressure and a secondary swing arm that enables folding motion. This multi-functional design eliminates the need for dedicated spring components while maintaining both display protection and folding capabilities.
2Reliability
If traditional foldable mechanisms use multiple structural members to implement folding, then the folding function is stable, but the terminal weight increases
Solution Approach 1:
By merging the floating plate and secondary swing arm into a single integrated component, the patent reduces the total number of parts and associated fasteners, thereby reducing overall terminal weight while maintaining folding stability through the unified structural design.
3Adaptability or versatility
If traditional foldable mechanisms use numerous parts for folding, then the folding function is achieved, but the structure is complex and not conducive to lightweight design
Solution Approach 1:
The patent merges multiple components (floating plate, secondary swing arm, and connecting structures) into an integrated design, reducing part count and simplifying the overall mechanism structure while preserving complete folding functionality.
Solution Approach 2:
The floating plate is designed as a multi-functional component that simultaneously provides floating support for display protection and serves as a secondary swing arm for folding motion, eliminating the need for separate dedicated parts.

AI summary
A foldable mechanism and a foldable terminal. The foldable mechanism includes a base, a connection assembly, and a floating plate. The connection assembly includes a first fixed frame and a first secondary swing arm. A first sliding portion of the first secondary swing arm is slidably connected to the first fixed frame, and a first rotating portion of the first secondary swing arm is rotatably connected to the base. A first connecting portion of the floating plate is slidably and rotatably connected to a first auxiliary portion. In the foldable mechanism, the floating plate can realize floating or sinking relative to the base under the driving of the first secondary swing arm.
