CCTV Camera Housing Glass Window Hybrid Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clear plastic domes used in PTZ cameras limit image quality, especially for high definition and high zoom cameras, as they are not clear enough to support high resolution and magnification.
Innovation Solution
A hybrid housing with a metal or opaque plastic base and a glass window, which allows for crystal clear images, incorporating a heating element to prevent moisture buildup and enabling easier cleaning and broader temperature range operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If clear plastic material is used for the dome housing, then weight is reduced and manufacturing cost is lowered, but image quality deteriorates for high definition and high zoom cameras
Solution Approach 1:
The patent applies composite materials by combining clear plastic material with glass optical elements. Specifically, a glass window or lens is integrated into the plastic dome housing, creating a hybrid structure that leverages the weight and manufacturing advantages of plastic while incorporating the superior optical clarity of glass to enable high definition imaging and high zoom capabilities
2Ease of manufacture
If clear plastic material is used for the dome housing, then manufacturing complexity is reduced, but image quality deteriorates
Solution Approach 1:
The patent combines simple plastic molding with precision glass optical elements. The plastic dome provides the structural housing through straightforward molding processes, while glass windows or lenses are integrated to provide the necessary optical quality for high definition and high zoom imaging, thus maintaining ease of manufacture while achieving superior image quality
3Manufacturing precision
If glass window is used in the housing, then image quality is improved, but cost increases
Solution Approach 1:
The patent applies local quality by using glass only in the specific location where optical performance is critical - the window or lens area in the field of view. The rest of the housing continues to use cost-effective clear plastic material. This localized approach to material selection achieves high definition image quality where needed while controlling overall manufacturing costs
4Manufacturing precision
If glass window is used in the housing, then zoom capability is improved, but weight increases
Solution Approach 1:
The patent uses glass only in the specific optical path area where it is needed for high quality imaging and zoom capability. The majority of the housing structure remains made of lightweight plastic material, thus achieving improved zoom capability through localized glass integration while minimizing the overall weight increase

AI summary
A camera housing incorporates a glass window, as an optical port, to improve image quality. The window can be curved or flat. The housing can be dome shaped and can also include metal or plastic along with the glass window. A camera installed in the housing has a field of view that intersects the window. The clear glass window enhances image quality when tilting or zooming the camera. A panning mechanism rotates the camera and housing together.
