Camera Bracket Vent Module for Waterproof Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in testing the waterproof function before the camera module is installed, leading to manufacturing inefficiencies and potential damage from water exposure, which can compromise the device's appearance and performance.
Innovation Solution
An electronic device design that includes a bracket with a vent hole module, allowing air to enter while preventing water ingress, enabling pre-assembly waterproof function testing and maintaining a sleek appearance by hiding the vent hole from the exterior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vent hole is exposed on the terminal exterior to allow air flow, then air circulation is improved, but the appearance elegance deteriorates
Solution Approach 1:
The vent hole function is extracted from the visible exterior surface and relocated to the interior of the terminal. The vent hole is formed in the rear cover rather than the external casing, separating the air flow function from the aesthetic appearance, thus maintaining elegance while enabling ventilation.
Solution Approach 2:
The camera module serves as an intermediary structure that houses the vent hole. By positioning the vent hole within the camera module's internal space rather than directly on the terminal exterior, the design mediates between the need for air flow and the requirement for elegant appearance.
2Reliability
If waterproof testing is performed after camera module assembly, then structural integrity is maintained, but manufacturing efficiency decreases and water damage risk increases
Solution Approach 1:
The terminal assembly is segmented into modular components (front cover, rear cover, camera module) that can be independently tested. The waterproof test can be performed on the rear cover and camera module assembly separately before final integration, enabling early detection of waterproof issues without requiring complete assembly.
Solution Approach 2:
Waterproof testing is performed preliminarily on the rear cover and camera module assembly before the final terminal assembly is completed. This preliminary action allows waterproof functionality to be verified early in the manufacturing process, preventing water damage and improving efficiency by avoiding rework of fully assembled units.
3Strength
If the camera module is fully assembled before waterproof testing, then component protection is improved, but testing accessibility and manufacturing cost worsen
Solution Approach 1:
The assembly process is segmented to allow the rear cover and camera module to be assembled and tested as a sub-assembly unit. This segmentation enables waterproof testing to be performed on a partially assembled structure that still provides adequate component protection, while maintaining accessibility for efficient testing procedures.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for effective waterproof testing before final assembly, reducing manufacturing costs and maintaining a refined appearance by ensuring the waterproof function is verified without exposing the vent hole, thus preventing deformation due to atmospheric pressure changes.
