Adjustable Lens Aiming Mechanism for Miniaturized Security Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniaturized security cameras face challenges in adjusting the direction of their lens, especially when mounted in difficult-to-access locations, as conventional methods require complex manipulation and are not easily adaptable for surreptitious surveillance.
Innovation Solution
A security camera apparatus with a lens adjustment mechanism featuring a mount, a circular contact ring, and a fastener that allows the lens to be adjusted and secured relative to a dome base, enabling easy rotation and secure fixing, even in compact or hard-to-reach positions, while maintaining a weatherproof seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the camera is miniaturized to enable surreptitious surveillance, then the camera can be placed in more locations and remain hidden, but the lens adjustment mechanism becomes difficult to implement and operate
Solution Approach 1:
The camera assembly is segmented into a camera unit and a housing unit that can be adjusted independently. The contact ring is segmented to allow rotational adjustment while maintaining sealing. This segmentation enables miniaturization of the overall device while preserving adjustment functionality through modular design.
Solution Approach 2:
The lens adjustment mechanism transitions from a static fixed mounting to a dynamic adjustable system. The camera can be rotated and repositioned within the housing using the adjustable mounting structure, allowing the lens direction to be changed without moving the entire camera unit, thus maintaining ease of operation in miniaturized form.
2Adaptability or versatility
If the camera is mounted in a difficult to access location, then surreptitious surveillance is enabled, but lens adjustment becomes much more difficult to perform
Solution Approach 1:
The adjustment mechanism is designed to be self-contained within the camera housing, allowing the lens direction to be adjusted from the front without requiring access to the back or mounting location. The adjustable mounting structure enables the camera to self-adjust its aiming direction through the contact ring mechanism, eliminating the need for manual manipulation at the mounting location.
Solution Approach 2:
The adjustment mechanism operates in a different dimensional space than the mounting location. The camera can be adjusted rotatorily around the contact ring axis without requiring physical access to the mounting brackets or rear components. This dimensional separation allows adjustment functionality to be decoupled from mounting accessibility.
3Adaptability or versatility
If a conventional lens adjustment mechanism is used, then lens direction can be adjusted, but the mechanism is complex and requires several steps and careful manipulation
Solution Approach 1:
The mounting structure and adjustment mechanism are merged into a single integrated contact ring assembly. The adjustable mounting brackets are combined with the sealing contact ring to form a unified structure that provides both mechanical adjustment and environmental sealing functions, thereby reducing overall mechanism complexity while maintaining adjustment capability.
Solution Approach 2:
The contact ring serves multiple functions simultaneously: it provides mechanical support for the camera, enables rotatory adjustment of lens direction, maintains weatherproof sealing, and allows for simple tool-free operation. This multi-functionality reduces the need for separate adjustment mechanisms, brackets, and sealing components, thereby simplifying the overall device complexity.

AI summary
A security camera with an adjustable lens aiming mechanism comprises a base with a camera seat, an eyeball camera, a cover, and a fastener for fastening the cover to the base. The eyeball camera comprises a lens and is movably seated on the camera seat. The cover covers the eyeball camera and comprises a bottom opening for engaging the base, a circular contact ring with a diameter smaller than the camera diameter and defining an opening through which the lens and a portion of the camera protrudes; and a fastener removably fastening the cover to the base such that when fully fastened, the contact ring makes contact with the camera and applies a sufficient pressure to fix the camera in place, and when partially or completely unfastened, the pressure is reduced such that the camera is movable and the lens is movable within the contact ring.
