Security Camera Tilt Motor Nesting and Belt Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing security camera systems have a complex structure and low space use efficiency due to the need for multiple support portions and separate spaces for motors, leading to increased size and complexity.
Innovation Solution
A security camera system with a single support portion and a cantilever-shaped design, where the tilt motor is coupled to the tilt axis via a belt, reducing the number of parts and space required, and incorporating a counterweight to minimize eccentric weight and prevent vibration and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple support portions and separate motor spaces are used, then the camera system can achieve stable support and motor function, but the structure becomes complex and space use efficiency decreases
Solution Approach 1:
The patent merges the support portion and motor housing into a single integrated structure. The support portion simultaneously serves as both the structural support element and the housing for the tilt motor, eliminating the need for separate motor mounting spaces and reducing overall structural complexity while maintaining functional reliability
2Reliability
If multiple support portions are used, then the camera module can be stably supported, but the number of parts increases and manufacturing cost increases
Solution Approach 1:
The support portion is designed as a single integrated component that combines multiple functions: structural support for the camera module, housing for the tilt motor, and mounting interface. This consolidation reduces the number of parts from multiple separate components to a single unified structure, thereby reducing manufacturing complexity and cost
3Ease of operation
If the tilt motor is arranged spaced apart from the tilt axis portion, then the motor can be fixed in the housing, but the structure becomes complicated and size increases
Solution Approach 1:
The tilt motor is nested within the support portion structure itself. The support portion is designed to house the motor internally, with the motor positioned adjacent to the tilt axis portion. This nesting arrangement eliminates the need for separate motor mounting spaces and reduces the overall camera system size while maintaining ease of motor fixing and operation

AI summary
A security camera system includes: a camera module; a support portion arranged at one side of the camera module and connected to a housing bracket or an outside structure; a tilt axis portion connected to one side of the camera module and coupled to the support portion to be rotatable relative to the support portion; and a tilt motor configured to transfer a rotation force to the tilt axis portion and revolve around a rotation axis of the tilt axis portion during rotation of the tilt axis portion.
