Rotating CCTV Camera Housing Cap with Elastic Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional CCTV camera housings are inconvenient to open and assemble, making frequent adjustments for focus, zoom, or diaphragm adjustments difficult due to secure fastening mechanisms.
Innovation Solution
A housing design featuring a housing cap with connecting protrusions and slots that allow easy rotation and locking, along with elastic second slots for secure attachment and disattachment, enabling easy assembly and disassembly of the camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing front portion and housing rear portion are securely fastened using bolts and nuts, then the camera is securely fixed and protected, but the housing becomes difficult to open for adjustments
Solution Approach 1:
The housing is divided into a housing cap and a housing body, allowing the cap to be easily removed for adjustments while the body remains stable. The connecting protrusions are segmented into multiple identical units distributed around the circumference, enabling modular assembly and disassembly.
Solution Approach 2:
The connection mechanism transitions from a static bolted joint to a dynamic snap-fit system using elastic deformation. The connecting protrusions can be inserted easily but lock securely when deformed, providing both ease of operation and reliable fixation through material elasticity rather than mechanical fasteners.
2Reliability
If the housing uses a secure fastening mechanism with bolts and nuts, then the camera is firmly fixed, but the assembly and disassembly process becomes time-consuming and troublesome
Solution Approach 1:
The connection system is segmented into multiple identical protrusions and slots, allowing parallel engagement of multiple connection points simultaneously. This reduces assembly time while maintaining secure fixation through the combined effect of multiple elastic locks.
Solution Approach 2:
The elastic connecting protrusions automatically lock into the slots upon insertion without requiring additional fastening actions. The system self-secures through elastic deformation, eliminating the need for manual tightening or securing operations that would consume time.
3Ease of operation
If the housing cap is easily removable for adjustments, then frequent focus and zoom adjustments become convenient, but the secure fixation of the camera may be compromised
Solution Approach 1:
The connection strength is changed dynamically through elastic deformation. When the housing cap is inserted, the protrusions deform elastically to create a strong locking force. When removed, the elastic force reverses to allow easy disengagement. The same structure provides both strong fixation and easy removal through parameter changes in material deformation.

AI summary
A housing for a CCTV camera is easily opened and assembled. The housing includes a housing cap having a filter glass, which filters incident light from an external light source and supplies the filtered light to a CCTV camera lens, on its front surface. One or more connecting protrusions are formed on a rear end of the housing cap along a circumference having a predetermined curvature. A camera case having as many first slots as connecting protrusions formed on its front surface accommodates and fixes the CCTV camera. The housing cap is easily locked and unlocked from the camera case by rotating the housing cap.
