Protective Case Hinge Mechanism for Multi-Angle Tablet Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective cases for tablet computers only allow for single-angle support, limiting the ability to adjust the support angle randomly and failing to meet user requirements in various application scenarios.
Innovation Solution
A hinge mechanism with a first and second rotating shaft assembly, connected to different portions of the protective case, allows for synchronized rotation of these portions, enabling adjustable support angles through a transmission part that cooperates with both shaft assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If soft rubber is used to connect support structures for simple rotation, then the structure is simple and easy to manufacture, but the support angle cannot be adjusted randomly and is limited to single-angle support
Solution Approach 1:
The protective case is divided into multiple portions (first portion, second portion, third portion) connected by separate rotating shaft assemblies. Each shaft assembly can rotate independently, allowing the case to achieve multiple support angles by combining different rotation angles of each segment, thus improving adaptability while maintaining manageable complexity through modular design.
Solution Approach 2:
The hinge mechanism incorporates two rotating shaft assemblies that enable dynamic adjustment of support angles. The first rotating shaft assembly connects the first and second portions, while the second rotating shaft assembly connects the second and third portions. Both assemblies allow random angle adjustment within their respective rotation ranges, transforming the static single-angle support into a dynamic multi-angle support system.
2Adaptability or versatility
If two rotating shaft assemblies are introduced to enable synchronized rotation, then random support angle adjustment is achieved, but the device complexity increases
Solution Approach 1:
The first and second rotating shaft assemblies are integrated through the shared second portion of the protective case. The transmission part connects both shaft assemblies, allowing them to work together as a coordinated system. This merging approach enables the two assemblies to function as a unified mechanism for achieving synchronized rotation and random angle adjustment, rather than operating as completely separate systems.
Solution Approach 2:
The second portion of the protective case serves as an intermediary component that connects both rotating shaft assemblies. It receives rotation from the first shaft assembly and transmits it to the third portion via the second shaft assembly. This intermediary structure allows the two shaft assemblies to cooperate efficiently, enabling random angle adjustment while distributing the mechanical complexity across multiple manageable components.

AI summary
An embodiment of this application provides a hinge mechanism, a protective case for an electronic device, and an electronic device assembly. The hinge mechanism is applied to the protective case for the electronic device. A first rotating shaft assembly in the hinge mechanism is fixedly connected to a first portion of the protective case, and is further rotatably connected to a second portion of the protective case. A second rotating shaft assembly in the hinge mechanism is fixedly connected to the second portion of the protective case, and is further rotatably connected to a third portion of the protective case. When the second portion of the protective case rotates relative to the first portion of the protective case by using the first rotating shaft assembly, a transmission part that cooperates with both the first rotating shaft assembly and the second rotating shaft assembly is configured to drive the third portion of the protective case to rotate relative to the second portion of the protective case by using the second rotating shaft assembly. Therefore, an adjustment of a random support angle of the electronic device can be implemented, so that a use requirement of a user in more application scenarios can be met, thereby improving use performance of the electronic device.
