Video Camera Casing with Integrated Stop Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video camera casings require extensive time and material for manufacturing and assembly due to the use of flange systems, leading to increased production costs and waste, while also being inefficient in sealing against harsh environments.
Innovation Solution
A casing design featuring a tubular body with integrated stop means and sealing gaskets for efficient sealing and assembly, eliminating the need for external flanges and reducing material usage, achieved through roll-forming operations to define internal stop and seating elements for precise positioning and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flange systems are used for assembling casing components, then sealing protection against harsh environments is achieved, but manufacturing time and assembly time are significantly increased
Solution Approach 1:
The patent merges the sealing function and the structural support function into a single integrated flange component. The flange is directly formed as part of the casing body through injection molding, eliminating the need for separate sealing elements and reducing the number of assembly steps while maintaining effective sealing protection.
Solution Approach 2:
The sealing features and flange structures are pre-integrated into the casing body during the injection molding process itself. This preliminary action eliminates subsequent separate operations for adding sealing elements or attaching flanges, thereby reducing manufacturing and assembly time while ensuring reliable sealing.
2Strength
If flange systems with welding are used for casing assembly, then structural strength is improved, but production costs increase due to cleaning and polishing operations
Solution Approach 1:
The patent combines the flange structure and sealing features into a single integrated component made through injection molding. This eliminates the need for separate welding operations and subsequent costly cleaning and polishing processes, reducing production costs while maintaining structural integrity through the molded design.
Solution Approach 2:
The patent replaces the mechanical welding system with an injection molding process that directly forms the flange and sealing features as integral parts of the casing. This substitution eliminates the need for post-welding cleaning and polishing operations, thereby reducing production costs.
3Reliability
If external flanges are used for casing components, then sealing capability is achieved, but material usage increases leading to waste
Solution Approach 1:
The patent merges the flange structure with the casing body into a single integrated component formed by injection molding. This eliminates the need for separate external flanges and reduces material usage, as the flange features are created as part of the molding process rather than as additional separate parts that would require extra material.
Solution Approach 2:
The injection molding process creates a multi-functional component that simultaneously provides the casing structure, the flange for assembly, and the sealing features. This universal approach eliminates the need for separate dedicated sealing elements and external flanges, reducing overall material consumption.

AI summary
A casing (1) for video cameras (100) comprising a tubular body (3) with substantially longitudinal development having the first end (3a) and the second end (3b) open and within which there is defined a housing (4) configured to house a support framework (2) for a video camera (100), a head element (5) made of transparent material positioned to close the first end (3a) and configured to be at least partly inserted into the tubular body (3), and a bottom element (6) positioned to close the second end (3b). The casing (1) further comprises first stop means (31) projecting towards the inside of the housing (4) so as to stop the advancement of the head element (5) in the closing position of the first end (3a), in which the first stop means (31) are defined by deformation of the outer surface of the tubular body (3) in proximity of the first end (3a), and corresponding method for obtaining the casing.
