Lightweight Remote Camera Head with Modular Pan and Tilt Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote camera heads for motion picture and video filming are not compact or lightweight, making them difficult to transport, install, and prepare for use efficiently.
Innovation Solution
A compact and lightweight camera head design featuring a pan frame with a pan motor for pan axis movement, a tilt frame with a tilt motor for tilt axis movement, and an optional roll axis module with a roll motor for roll axis movement, allowing for two-axis or three-axis control, with a slide-out mechanism for accommodating varying camera sizes and payloads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional remote camera heads are used, then camera positioning capability is achieved, but weight and size are excessive making transportation and installation difficult
Solution Approach 1:
The camera head is divided into modular components including pan mechanism, tilt mechanism, and camera platform that can be assembled and disassembled independently. This segmentation reduces the weight of individual transport units while maintaining full functionality when assembled together.
Solution Approach 2:
The patent employs dynamic balancing mechanisms and adjustable counterweights that can be reconfigured during operation. This allows the system to optimize its weight distribution and reduce effective operational weight, making transportation and installation easier while maintaining positioning capability.
2Volume of moving object
If camera head size is reduced for portability, then transportation ease improves, but payload accommodation capability deteriorates
Solution Approach 1:
The camera platform is designed with nested or telescopic structures that can expand to accommodate larger cameras when needed and contract to a compact form for transportation. This nesting principle allows the same structure to serve both portability and payload accommodation requirements.
Solution Approach 2:
The camera head incorporates dynamically adjustable support arms and platform extensions that can be deployed when larger cameras need to be accommodated and retracted during transport. This dynamic adaptability resolves the contradiction between compact size and payload versatility.
3Productivity
If quick installation is achieved, then productivity improves, but structural stability may deteriorate
Solution Approach 1:
The camera head uses pre-assembled modular segments with standardized connection interfaces. These segments can be quickly attached and detached without requiring complex assembly procedures, thereby improving installation speed while maintaining structural integrity through precision-engineered connection points.
Solution Approach 2:
Critical structural components are pre-assembled and pre-balanced during manufacturing, with alignment features and locking mechanisms prepared in advance. This preliminary action ensures that when the camera head is installed quickly on-site, the pre-prepared structural elements maintain stability without requiring time-consuming field adjustments.

AI summary
A remotely controlled camera head has a pan frame including a first rectangular section. An upper end of a second rectangular section is joined to the left side of the first rectangular section. A pan motor in the first rectangular section of the pan frame rotates the pan frame about a pan axis co-axial with a hub when the pan motor is on. A tilt frame is rotatably attached to the lower end of the second rectangular section and movable about a tilt axis. In a two axis mode, a camera platform is attached to the tilt frame. A slide out may be used to change the length of the tilt frame. A tilt motor within the second rectangular section is connected to the tilt frame for rotating the tilt frame about a tilt axis when the tilt motor is on.
