Single-Piece Dual-Head Dome Cover for Compact IR Camera Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual-head monitoring cameras are limited by the size and shape of their protective covers, which restrict miniaturization and flexibility in component placement, and do not effectively accommodate infrared sensors and illumination sources.
Innovation Solution
A dual-head dome camera design featuring a single, dome-shaped protective cover with transparent sections for visible light and opaque sections for aesthetics, allowing for compact size, flexible component placement, and integration of infrared sensors, along with a bracket for structural support and cable concealment, and anti-reflection components for improved image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional protective cover shape is used, then the camera heads are protected, but the overall camera size cannot be reduced and component placement flexibility is limited
Solution Approach 1:
The dome cover is divided into multiple dome-shaped sections, each covering a camera head, with a center section joining them. This segmentation allows the cover to adapt to the specific arrangement of camera heads while maintaining a compact overall structure.
Solution Approach 2:
The single-piece dome cover serves multiple functions: it protects multiple camera heads simultaneously, provides structural support, and allows for flexible component placement within the camera housing while maintaining a unified aesthetic appearance.
2Reliability
If multiple smaller dome covers are used for each camera head, then each camera head is protected, but manufacturing and assembly become more complex
Solution Approach 1:
Multiple dome-shaped sections are merged into a single integrated dome cover that protects all camera heads simultaneously. This unified structure simplifies manufacturing to a single molding process and assembly to a single installation step, while maintaining reliable protection for each camera head through the segmented dome sections.
3Illumination intensity
If the dome cover is made transparent, then visible light reaches the camera heads, but internal components become visible reducing aesthetics
Solution Approach 1:
The dome cover is constructed with different transparency properties in different regions: transparent sections where camera heads are located to allow light transmission, and opaque sections in areas where internal components like cables and connectors are visible, thereby maintaining aesthetic appearance. This local differentiation of optical properties resolves the contradiction between light transmission and aesthetics.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables a more compact and versatile dual-head camera that can be mounted in smaller spaces, simplifies manufacturing and assembly, and enhances image quality by minimizing image distortions and reflections, while supporting infrared functionality and aesthetic appeal.
Implementation Method 1
the dome cover is at least partly transparent. This allows visible light to pass through the dome cover and reach the camera heads
Implementation Method 2
the plastic is transparent to infrared light. This increases the use scenarios for the dual head camera, as not only visible light sensors, but also infrared sensors and illumination sources can be mounted inside the dome camera
Implementation Method 3
the infrared illumination sources are mounted on the base and comprise an anti-reflection component configured to reduce the amount of light from the infrared illumination sources being reflected to the camera heads

AI summary
A dome camera has a base, two camera heads and a dome cover. The base is configured for mounting the dome camera to a surface. The two camera heads are arranged on the base. The dome cover is arranged over the camera heads and the base. The dome cover includes at least two dome-shaped sections, wherein each dome-shaped section covers a camera head, and a center section joining the dome-shaped sections. The dome cover is formed in a single piece.
