Camera Dome Cover Light-Shielding and Integral Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dome covers for cameras suffer from image blurring due to lens effects and durability issues, particularly when the camera's tilt angle exceeds a threshold, and may have a narrow visually-recognizable range or be prone to cracking at connecting points.
Innovation Solution
A dome cover with a curved section and a skirt section, both integrally molded, featuring a light-shielding part that shields light incident from or emitted by these sections, reducing lens effects and enhancing durability by eliminating connecting points that can crack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a dome cover is formed by connecting two components, then manufacturing flexibility is improved, but durability deteriorates due to cracking at connecting parts
Solution Approach 1:
The patent merges the curved section and skirt section into a single integrally molded component, eliminating the connecting part that causes cracking. This resolves the durability issue while maintaining manufacturing efficiency through integral molding.
2Manufacturing precision
If a light-shielding part is provided to suppress lens effect, then image quality is improved, but manufacturing complexity increases
Solution Approach 1:
The light-shielding part is integrated into the dome cover as a single molded component, combining the light-shielding function with the structural form. This eliminates separate assembly steps and reduces manufacturing complexity while maintaining image quality.
Solution Approach 2:
The dome cover uses composite material construction with light-shielding properties built into the material or structure, achieving light-shielding functionality without adding separate components or complex assembly processes.
3Reliability
If the curved section and skirt section are integrally molded, then durability is improved by eliminating connecting parts, but manufacturing precision requirements increase
Solution Approach 1:
The integral molding process is divided into distinct functional sections (curved section and skirt section) with a defined boundary surface, allowing precise control of geometry and light-shielding features while maintaining overall structural integrity.
Solution Approach 2:
The light-shielding part is positioned at specific locations (boundary surface or front surface) with precise local geometry, achieving the required optical function without compromising overall molding quality or requiring excessive precision throughout the entire component.

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 solution suppresses blurring and maintains a wide visually-recognizable range while improving durability and reducing manufacturing costs by integrating the curved and skirt sections, thus preventing cracking and burr formation.
Implementation Method 1
a light-shielding part that shields a part or whole of at least one of light that is incident from the skirt section and is emitted from the curved section or light that is incident from the curved section and is emitted from the skirt section
