Surveillance Camera Internal Assembly Frame for Scratch-Free Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surveillance camera assembly processes are complex and prone to damaging the external housing, which is often scratch-sensitive, and do not allow for easy testing of the camera's functionality before final assembly.
Innovation Solution
The camera employs an internal assembly frame that holds and aligns the motorized object lens adjusting, image processing, and interface modules without the external housing, allowing for screwless attachment and easy cable management, enabling the camera to be tested before the external housing is mounted, thus simplifying assembly and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If modules are assembled inside the external housing, then the camera structure is compact, but the assembly process becomes complex and the external housing is prone to damage
Solution Approach 1:
The camera is divided into two main segments: an internal assembly frame containing all modules (lens adjusting module, image processing module, interface module) and the external housing. This segmentation allows the complex module assembly to be performed on the internal frame separately, simplifying the overall assembly process while maintaining compact final structure.
Solution Approach 2:
The internal assembly frame serves as an intermediary structure between the modules and the external housing. All modules are first assembled and tested on this intermediate frame, then the complete assembly is mounted into the external housing as a single unit, reducing assembly complexity and protecting the housing.
2Ease of manufacture
If the external housing is used during assembly, then the camera is complete, but the scratch-sensitive housing is at risk of damage
Solution Approach 1:
All module assembly, cable management, and functionality testing are performed in advance on the internal assembly frame before the external housing is attached. This preliminary completion of assembly tasks eliminates the need to handle or assemble inside the housing, thereby protecting it from scratches and damage.
3Stability of the object's composition
If the external housing is attached early in assembly, then the camera structure is stable, but testing functionality becomes difficult
Solution Approach 1:
The conventional sequence is inverted: instead of attaching the housing first and then assembling modules inside, the modules are fully assembled and tested on the internal frame first, then the complete module assembly is mounted into the housing. This inversion enables easy accessibility for testing while achieving structural stability in the final product.
4Reliability
If modules are attached without screwless mechanism, then secure fixation is achieved, but assembly time increases
Solution Approach 1:
The traditional mechanical screw-based fastening system is replaced with a screwless attachment mechanism on the internal assembly frame. This substitution maintains secure fixation of modules while significantly reducing assembly time and complexity, thereby improving productivity without sacrificing reliability.

AI summary
Surveillance cameras are for example used in surveillance networks for observing areas of public places, schools, universities, private households, prisons etc. Usually such a surveillance networks comprises a plurality of cameras and a surveillance control center, whereby the cameras are connected by public or private network with the surveillance control center, so that images, captured y the cameras can be transferred to the surveillance control center. A camera (1) comprising a motorized object lens adjusting module (3) for adjusting the object lens or parts thereof, an image processing module (4) for processing the images captured by the camera (1), an interface module (5) for providing Signal interfaces and an external housing enclosing the modules (3, 4, 5), is disclosed, with an internal assembly frame (8) for holding the said modules (3,4,5) as a unit (8) independently from the external housing.
