Ventilation Member in Camera Module Housing for Pressure Equalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of ventilation holes in camera modules is limited by the dense arrangement of lenses, flash units, and microphone holes, making it difficult to achieve required ventilation performance without compromising the aesthetics of the electronic device.
Innovation Solution
Incorporating a ventilation member within the housing of the electronic device, which includes a receiving hole for external devices and a through-hole fluidically connecting the receiving hole and the inner space, allowing for optimized ventilation performance without visible ventilation holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ventilation holes are formed in the housing to maintain pressure equilibrium, then ventilation performance is improved, but the aesthetics of the electronic device deteriorates
Solution Approach 1:
The ventilation function is extracted from the main housing body and relocated to the camera module. The through-hole is formed in the camera module's lens barrel, separating the ventilation function from the housing's aesthetic surface. This allows the housing to maintain its appearance while the camera module provides the necessary ventilation pathway.
Solution Approach 2:
The ventilation hole is nested within the camera module structure, specifically in the lens barrel that protrudes from the housing. This nested arrangement allows the ventilation opening to be hidden within an existing structural element, maintaining the overall aesthetic appearance while providing the required ventilation function.
2Reliability
If ventilation holes are formed in the camera module, then ventilation performance is improved, but the design flexibility is limited due to dense arrangement of lenses, flash, and microphone holes
Solution Approach 1:
The ventilation hole is positioned on the lateral surface of the lens barrel rather than on the top or front surfaces where lenses, flash, and microphone holes are densely arranged. This utilization of the lateral dimension provides an additional design space that is not constrained by the dense arrangement of other components.
Solution Approach 2:
The camera module is segmented into multiple functional regions, with the ventilation function assigned to the lens barrel structure. This segmentation allows the ventilation hole to be independently positioned and sized without interfering with the arrangement of lenses, flash, and microphone holes in other regions of the camera module.
3Adaptability or versatility
If the receiving hole is designed to accommodate external devices, then adaptability is improved, but the structural complexity increases
Solution Approach 1:
The receiving hole in the lens barrel serves multiple functions: it provides a pathway for ventilation, accommodates the protruding portion of external devices, and maintains the structural integrity of the camera module. This multi-functionality reduces the need for separate structural elements, thereby reducing overall structural complexity.
Solution Approach 2:
The ventilation pathway and the device accommodation function are merged into a single structural feature - the receiving hole in the lens barrel. This merging eliminates the need for separate ventilation openings and device receptacles, simplifying the overall structure while maintaining both functions.
