Pan-Tilt Camera Mounting That Keeps Images Level Without Roll
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security camera systems require additional mechanical complexity for wall mounting, as they need rotational movement to maintain a level image, which is not necessary for ceiling mounting, leading to increased mechanical and electronic complexity.
Innovation Solution
A camera system with a support body and motors or manual adjustment mechanisms that allow pan and tilt movements without rotational movement, maintaining a level image when mounted on either a ceiling or wall by keeping the pan axis vertical, thus eliminating the need for Z-axis gimbal rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional 3-axis gimbal with rotational movement is used for wall mounting, then the image can be level with the ground, but the mechanical and electronic complexity increases
Solution Approach 1:
The patent extracts and removes the Z-axis rotational movement mechanism from the conventional 3-axis gimbal system. By eliminating this component, the system achieves image leveling for wall-mounted cameras without requiring the additional mechanical complexity of a third rotational axis, thus resolving the contradiction between reliability and device complexity
Solution Approach 2:
The patent creates a universal mounting system that can be installed on either ceilings or walls without requiring different mechanical configurations. The same pan-tilt mechanism maintains vertical pan axis orientation in both mounting scenarios, eliminating the need for wall-specific rotational mechanisms and reducing overall system complexity while maintaining multi-functional adaptability
2Adaptability or versatility
If additional rotational mechanisms are added for wall mounting, then the image can be maintained level, but the device complexity and component quantity increase
Solution Approach 1:
The patent implements a universal mounting system where the same pan-tilt camera mechanism can be installed on ceilings or walls without requiring additional rotational components. The system achieves adaptability through proper orientation of the pan axis in the vertical direction regardless of mounting surface, eliminating the need for wall-specific rotational mechanisms
Solution Approach 2:
The patent removes the Z-axis rotational mechanism from the system entirely. By extracting this component, the system achieves wall-mounting capability without increasing the quantity of mechanical parts, resolving the contradiction between adaptability and device complexity

AI summary
A camera system is disclosed that enables movement in the pan and tilt directions while maintaining a level image when wall or ceiling mounted. The camera system includes one or more motors to pan or tilt the camera, but does not include a motor to rotate the camera image. The camera system can have a wall-mounted or ceiling-mounted configuration, with the pan axis of the camera in the vertical direction. In this way, movements in the pan or tilt direction of the camera maintain the level image, thereby avoiding any need to rotate the camera. For example, the camera system may include a support body and a camera subsystem, which includes the camera. The position of the support body relative to the camera may be different in the wall-mounted configuration versus the ceiling-mounted configuration; however, in both configurations, the camera can have its pan axis in the vertical direction.
