Sliding Rotating Hinge for One-Handed Folder Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folder-type portable communication devices are inconvenient for users to open with one hand due to their design, requiring two hands to operate the hinge device.
Innovation Solution
A portable communication device equipped with a sliding, rotating hinge mechanism that allows the second housing to be easily opened by sliding it a small distance, causing the hinge to automatically rotate and open the device, enabling one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional hinge device is used to open the folder, then the folder can be opened, but the user requires two hands to operate it, causing inconvenience
Solution Approach 1:
The hinge device is divided into multiple functional components: a hinge body, a movable arm that slides within the hinge body, and a rotating mechanism. This segmentation allows the opening operation to be broken into distinct phases (sliding then rotating), enabling one-handed operation while maintaining structural functionality
Solution Approach 2:
The hinge device incorporates dynamic movement mechanisms where the movable arm transitions from a sliding motion to a rotating motion. This dynamic behavior allows the device to adapt its movement mode based on the operational phase, providing ease of one-handed opening while managing the complexity through automated motion transitions
2Ease of operation
If the folder is designed to open with a conventional hinge, then the structure remains simple, but the user cannot easily open it with one hand
Solution Approach 1:
The hinge mechanism is pre-configured with a movable arm positioned within the hinge body that is ready to slide upon user input. This preliminary positioning allows the user to initiate opening with a simple sliding action, after which the mechanism automatically transitions to rotation, achieving one-handed operation without requiring complex user manipulation
Solution Approach 2:
The hinge mechanism performs the rotation action automatically after the user initiates the sliding motion. The movable arm, once slid to a predetermined position, automatically triggers the rotating mechanism to open the folder. This self-service capability reduces the operational burden on the user, enabling one-handed operation while managing complexity through automated mechanism engagement

AI summary
A portable communication device and a sliding and rotating hinge apparatus are provided. The device includes a first housing; a second housing, facing the first housing when the device is in a folded state; and a hinge unit. The hinge unit has a first portion attached to the second housing and is configured to slide, together with the second housing, with respect to the first housing to reach a disengaged position. A second portion of the hinge unit automatically rotates once the disengaged position is reached, thereby automatically rotating the second housing around a hinge axis of the hinge unit to open the device to an unfolded state.
