Camera Protection Assembly With Dual Waterproof Seals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with flexible displays face challenges in maintaining waterproofing and structural integrity, especially around camera components, which are prone to damage from external impacts and environmental factors.
Innovation Solution
The electronic device incorporates a housing with a rear plate, display, camera, and waterproofing members, including a lower and middle bracket with waterproofing material, to provide seals and protect the camera from water ingress and structural damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera protective member is added to protect the camera from external impacts and water ingress, then the reliability and waterproofing of the camera are improved, but the device complexity increases
Solution Approach 1:
The camera protective member is divided into multiple functional components: a camera window for optical protection, upper and lower brackets for structural support and positioning, and waterproofing members for sealing. This segmentation allows each component to perform its specific function while collectively providing comprehensive protection without unnecessary complexity.
Solution Approach 2:
The protective structure employs a nested arrangement where the camera window is positioned within the bracket assembly, which itself is mounted on the housing. The waterproofing members are integrated between the bracket components and the camera window, creating a compact nested structure that maximizes protection while minimizing space occupation.
2Reliability
If multiple waterproofing members are used to seal between brackets and camera window, then the waterproofing effectiveness is improved, but the manufacturing complexity increases
Solution Approach 1:
Waterproofing members are strategically positioned at specific critical interfaces where water ingress would occur: between the lower bracket and housing, between the upper bracket and housing, and between the camera window and brackets. This localized approach to waterproofing ensures effective sealing at key points without requiring complete sealing of every surface, simplifying the overall manufacturing process.
Solution Approach 2:
The waterproofing members act as intermediary sealing elements between the rigid bracket components and the camera window. These intermediate sealing members accommodate minor dimensional variations and assembly tolerances while maintaining effective waterproof seals, reducing the need for precision machining and complex assembly procedures.

AI summary
An electronic device may comprise a housing forming at least a portion of an outer surface of the electronic device and including a rear plate, a display disposed opposite to the rear plate on the housing, a camera disposed in the housing and aligned with an opening formed in the rear plate, a camera window disposed to cover the camera, a lower bracket at least partially disposed on an inner surface of the rear plate to protrude through the opening formed in the rear plate, a middle bracket disposed on the lower bracket and configured to support the camera window, an upper bracket disposed on the middle bracket, a first waterproofing member disposed between the middle bracket and the lower bracket to provide a first waterproof seal between the middle bracket and the lower bracket, and a second waterproofing member disposed between the middle bracket and the camera window to provide a second waterproof seal between the middle bracket and the camera window. Other various embodiments are possible.
