Battery Cover Glass Substrate Camera Region Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery covers in electronic devices, such as mobile phones and tablets, face issues with dust and liquid ingress through camera through-holes, leading to potential camera damage and increased manufacturing complexity due to the use of separate camera lenses and decorating parts, which can detach under chronic friction.
Innovation Solution
A battery cover design featuring a glass substrate with a non-transparent layer and film-coated camera region, where the first through-hole is disposed on the non-transparent layer opposite to the camera assembly, eliminating the need for a through-hole on the glass substrate, thus preventing dust and liquid ingress and enhancing the camera's flatness and light transmittance without a camera lens, thereby improving assembly efficiency and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera lens and decorating part are used with a through-hole in the glass substrate, then the camera assembly can function properly, but dust and liquid can enter through the through-hole causing camera damage
Solution Approach 1:
The patent removes the camera lens and decorating part from the traditional structure, extracting only the essential function of light transmission. The glass substrate itself is modified with a camera region that directly transmits light to the camera assembly without requiring separate lens components or through-holes, thereby eliminating the harmful opening while preserving camera functionality.
Solution Approach 2:
The patent merges the camera lens function and the glass substrate into a single integrated structure. The camera region of the glass substrate directly performs light transmission without requiring separate lens components, combining multiple functions into one element and eliminating the need for through-holes that would compromise sealing.
2Reliability
If separate camera lens and decorating part are used, then camera function can be achieved, but manufacturing complexity and assembly operations increase
Solution Approach 1:
The patent merges the camera lens function and the decorating part into the glass substrate itself. The camera region of the glass substrate directly performs light transmission and aesthetic functions without requiring separate lens components or decorating parts, significantly reducing manufacturing complexity and assembly operations.
Solution Approach 2:
The glass substrate is designed to perform multiple functions simultaneously: it serves as the structural cover, the aesthetic decorating element, and the optical transmission component for the camera. This multi-functionality eliminates the need for separate dedicated components for each function.
3Reliability
If camera lens and decorating part protrude from the battery cover, then camera photographing standard can be met, but the camera lens is prone to fraying and scratching
Solution Approach 1:
The patent merges the camera lens function with the glass substrate, eliminating the need for a separate protruding camera lens. The camera region of the glass substrate maintains the necessary optical properties while being protected by the overall battery cover structure, preventing fraying and scratching of exposed lens elements.

AI summary
Embodiments of the present invention provide a battery cover and an electronic device, and relate to the field of electronic devices, to resolve at least a problem that liquid or dust enters the electronic device through a camera through-hole. The battery cover is applied to the electronic device and configured to connect a housing of the electronic device, and includes a glass substrate. A non-transparent layer is disposed on a first side of the glass substrate. At least one first through-hole is disposed on the non-transparent layer, and the first through-hole is disposed opposite to a camera assembly disposed in the electronic device. A camera region is disposed on the first side of the glass substrate, and the camera region is disposed opposite to the at least one first through-hole. A film-coated layer is disposed in the camera region of the glass substrate. An area of the camera region is greater than or equal to an area of the first through-hole. In the embodiments of the present invention, the first through-hole is disposed on only the non-transparent layer, and no through-hole needs to be disposed on the glass substrate. Therefore, when the battery cover is applied to the electronic device, the dust or the liquid can be effectively prevented from entering the electronic device.
