Camera Head with Adjustable Tilt Arms and Counterweight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera stabilization systems face challenges in maintaining camera stability when mounted on moving vehicles, particularly in achieving precise control over pan, tilt, and roll axes, due to unwanted lens movement and imbalance in camera loading.
Innovation Solution
A camera head system with pivotally attached pan and tilt frames, adjustable length arms, and a dual-loop feedback control system that uses sensors and motors to stabilize the camera platform, allowing for precise control and balance adjustments to maintain steady camera positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is mounted on a moving vehicle to follow action or achieve desired camera angles, then the camera can capture dynamic scenes, but maintaining camera stability becomes difficult
Solution Approach 1:
The patent employs a counterweight mechanism where a balance arm with adjustable counterweight compensates for the camera weight, creating gravitational balance around the tilt axis. This reduces the torque required from the tilt motor and improves stability during vehicle movement while maintaining camera mobility
2Stability of the object's composition
If existing stabilization systems use sensors and motors to counteract lens movement, then camera stability improves, but the system complexity increases
Solution Approach 1:
The patent introduces a mechanical counterweight system that passively balances the camera weight through gravitational forces. This reduces the burden on active stabilization components (motors and sensors), allowing for a simpler overall system design while maintaining effective stabilization
Solution Approach 2:
The patent implements adjustable length arms and adjustable counterweight positions that can be dynamically configured based on camera weight and desired center of gravity location. This adaptability allows the system to optimize performance for different camera configurations without requiring complex automated adjustment mechanisms
3Adaptability or versatility
If the camera platform is extended to accommodate cameras requiring more vertical clearance, then adaptability improves, but the center of gravity balance becomes harder to maintain
Solution Approach 1:
The patent employs adjustable length tilt arms and adjustable counterweight positions that can be reconfigured based on the specific camera installation requirements. When vertical clearance is increased, the counterweight position can be adjusted to maintain proper center of gravity balance, preserving system adaptability while ensuring stability

AI summary
A camera support has a pan frame pivotably attached to a support hub. The support hub is attached to a camera crane. The pan frame has first and second spaced apart and parallel adjustable length pan arms. A pan motor is attached to the pan frame and adapted to pivot the pan frame about a pan axis relative to the support hub. A tilt frame is pivotably attached to the pan frame. A tilt motor is attached to the tilt frame and to the pan frame and is adapted to pivot the tilt frame about a tilt axis perpendicular to the pan axis. The adjustable length tilt arms allow the camera head to extend to accommodate cameras requiring more vertical clearance. The adjustable length tilt arms allow the camera platform to be moved to better locate the center of gravity of the camera on the tilt axis.
