Multi-Camera Apparatus with Rotating Mounts for Rapid Panning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional CCTV camera systems experience reduced moving speed and increased shaking during panning operations due to the location of the driving motor and increased radius of rotation, leading to deteriorated capturing quality.
Innovation Solution
A multi-camera apparatus with a driving base and camera mounts that move along a circumference with a reduced radius of rotation, utilizing a shaft and regulators to maintain constant height and prevent shaking, while power transmitters with motors enable rapid movement and image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the driving motor is located in the rotational axis with a guide rail, then the camera can perform panning operation, but the radius of rotation is increased requiring more torque and significantly reducing moving speed
Solution Approach 1:
The driving motor is extracted from the rotational axis and relocated to the camera mount. This removes the source of the problem (large radius of rotation) while preserving the panning function. The motor now drives the camera mount directly, eliminating the need for a guide rail and reducing the rotational radius to minimal levels.
Solution Approach 2:
Instead of having the camera rotate around a fixed axis with the motor at the center, the invention inverts the arrangement by placing the motor at the camera mount itself. This reverses the traditional panning mechanism architecture, allowing the camera to achieve rotation with a much smaller effective radius and lower power requirements.
2Reliability
If the camera moves on the guide rail, then panning operation is enabled, but shaking continually occurs deteriorating capturing quality
Solution Approach 1:
The guide rail is completely removed from the system. By extracting this mechanical constraint, the invention eliminates the source of shaking that occurred during camera movement. The camera mount now rotates directly on its mounting position without sliding along a rail, preventing the continuous shaking that deteriorated image quality.
3Adaptability or versatility
If the radius of rotation is increased to enable panning, then the camera can cover wider area, but more torque is required and moving speed is reduced
Solution Approach 1:
The guide rail structure that enforced a large radius of rotation is extracted and removed. The camera mount is free to rotate with minimal radius, achieving rapid panning responses. The wide area coverage is maintained through the responsiveness and speed of the new mechanism rather than through a large rotational arc.

AI summary
A multi-camera apparatus includes: a driving base in which a movement path is formed; at least one camera mount, each of which includes a respective camera module mounted therein, and is configured to contact the driving base and move along the movement path; and a shaft provided at a center of the driving base and coupled to the driving base, wherein each of the at least one camera mount is connected to the shaft and configured to move along a circumference of the driving base with the shaft as a rotational center.
