Rotating Module Damping Structure for Foldable Hover Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rotating modules in foldable electronic devices lack a damping sense during rotation, only allowing for locking in unfolded or folded states without intermediate hovering positions.
Innovation Solution
Incorporation of a damping member with elastic properties, such as springs or elastic pieces, that generates a damping force between rotating members, enabling stable hovering at various positions between unfolded and folded states through friction and elastic deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotating module without damping member is used, then the structure is simple and easy to manufacture, but the rotating member cannot hover at intermediate positions and only has locking functions for opening and closing positions
Solution Approach 1:
A damping member is introduced as an intermediary component between the rotating member and the support. This damping member includes a damping element that generates damping force during rotation, enabling the rotating member to hover at intermediate positions. The damping member acts as a mediator that provides the necessary damping effect without requiring complex mechanical structures or additional actuating mechanisms.
Solution Approach 2:
The damping member changes the dynamic parameters of the rotating system by introducing damping force. The damping element (such as a damper or damping material) alters the motion characteristics of the rotating member, enabling it to maintain intermediate positions through friction and damping effects rather than requiring precise mechanical locking at every position.
2Reliability
If a damping member is added to enable hovering at intermediate positions, then the hovering function is achieved, but the structure becomes more complex
Solution Approach 1:
The damping member serves as a compact intermediary component that integrates multiple functions: it provides damping force, enables hovering at intermediate positions, and maintains structural stability. By using a single damping member with a damping element rather than multiple separate mechanisms, the solution achieves reliable hovering functionality while minimizing the increase in device complexity.
Solution Approach 2:
The damping member is designed to perform multiple functions simultaneously: it provides damping during rotation, enables the rotating member to hover at intermediate positions, and maintains stability throughout the rotation range. This multi-functional design reduces the need for additional specialized components, thereby limiting the increase in device complexity while achieving the desired reliability.
3Reliability
If a damping member with elastic properties is used, then damping force is generated for stable hovering, but the device occupies more space
Solution Approach 1:
The damping element is nested within or integrated into the damping member structure, which itself is integrated with the rotating module. This nested arrangement allows the damping component to occupy minimal space within the existing structural envelope of the rotating module, rather than requiring additional external space.
Solution Approach 2:
The damping member utilizes flexible damping elements (such as elastic materials or thin-film dampers) that can provide sufficient damping force while occupying minimal volume. These flexible components can be configured in space-efficient geometries that deliver the required damping performance without significantly increasing the overall volume of the rotating module.

AI summary
The disclosure relates to a rotating module and an electronic device. The rotating module includes a support (130), a rotating member, and an elastic damping member (140). The rotating member includes a first rotating member (110) and a second rotating member (120), the first rotating member (110) and the second rotating member (120) are connected to the support (130) respectively. A first end of the damping member (140) is fixed to the support (130). A second end of the damping member (140) is in contact with the rotating member to provide the first rotating member (110) and the second rotating member (120) with a damping force for relative rotation of the first rotating member (110) and the second rotating member (120). The second end is an opposite end of the first end. The support (130) is disposed between the rotating member and the damping member (140).
