Rotating Bracket and Sliding Camera Cover for Foldable Phone Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional phone protective shells expose the camera, leading to wear and tear, and struggle to provide stable support for foldable screen phones, causing inconvenient use.
Innovation Solution
An electronic-device protective shell with a rotatable bracket plate and sliding camera cover that can expose or protect the camera, combined with a hinge structure that includes damping sleeves for adjustable support, ensuring stable support for foldable screen phones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera is directly exposed outside the phone shell, then the camera is easily accessible for photos, but the camera is likely to be worn and affected service life
Solution Approach 1:
The camera cover is designed to be slidable relative to the bracket plate, allowing it to dynamically transition between covering and exposing the camera hole. This dynamic structure enables the camera to be protected when not in use while remaining accessible when needed, resolving the contradiction between durability and ease of operation
Solution Approach 2:
The camera cover acts as an intermediary element between the camera and the external environment. It can be slid to cover the camera hole, providing protection, or moved away to expose it for use, thus mediating between the need for protection and the need for accessibility
2Device complexity
If a conventional support member is used, then the structure is simple, but it is difficult to stably support the phone body with large weight
Solution Approach 1:
The bracket plate is rotatably connected to the shell body, allowing it to dynamically adjust between a folded position (flush with shell body) and an extended support position. This dynamic adjustment enables the support structure to adapt to different usage scenarios while providing stable support when extended, without significantly increasing overall device complexity
Solution Approach 2:
The support member extends in a direction substantially perpendicular to the camera hole, utilizing the third dimension (depth/height) to provide support functionality. This spatial arrangement allows the bracket plate to extend outward to support the phone body weight while maintaining a compact profile when folded, effectively adding support capability without proportionally increasing complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively protects the camera from damage and provides stable support for foldable screen phones, allowing users to adjust the support angle as needed, enhancing usability and durability.
Implementation Method 1
The damping sleeve increases the rotary friction force between the second hinge head and the second hinge seat, allowing the bracket plate to hover at any position within the rotational range

AI summary
The present invention relates to an electronic-device protective shell including a shell body provided with an accommodating chamber and a camera hole in communication with the accommodating chamber. The accommodating chamber is used for accommodating an electronic device, and the camera hole is used for exposing a camera of the electronic device. A support member is disposed on an outer surface of the shell body, and the support member includes a bracket plate and a camera cover. The bracket plate is rotatably connected to the shell body, and the camera cover is slidable with respect to the bracket plate to cover or expose the camera hole.
