Camera Crane Mobile Base with Corner Drive Motors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a mobile camera crane base that can support larger crane arms while being easily transported and maneuvered, especially in outdoor filming locations where space and stability are critical, and the existing solutions lack the versatility and portability required for remote-controlled camera operations.
Innovation Solution
A mobile camera crane base with a rectangular chassis equipped with drive motor assemblies at each corner, allowing for independent motor control, a pivotable column for lateral and longitudinal movement, and a telescoping crane arm, along with a steering system for multiple steering modes, enabling stable and versatile camera positioning and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the mobile base is made compact for easy transportation, then portability is improved, but the ability to provide a steady and rigid platform for larger crane arms deteriorates
Solution Approach 1:
The mobile base is divided into a compact chassis for transportation and an expandable support structure with outriggers that can be deployed during operation. This segmentation allows the base to maintain a compact form for portability while providing a stable, expanded platform when in use, resolving the contradiction between compactness and stability.
2Adaptability or versatility
If larger and more versatile camera cranes are designed to match remote control capabilities, then camera positioning versatility is improved, but the complexity and difficulty of transportation and maneuvering deteriorates
Solution Approach 1:
The mobile base incorporates dynamically adjustable components including variable speed motors, steerable wheels, and deployable outriggers that can be configured based on operational needs. This dynamic adaptability allows the base to handle versatile camera positioning requirements while maintaining manageable complexity through controlled, on-demand functionality rather than permanently complex structures.

AI summary
A camera crane has a telescoping arm on a mobile base. The mobile base has a drive motor assembly at each corner of a chassis. The drive motor assemblies may have an electric motor linked to an axle via gearing, and two or more wheels attached to the axle. The wheels can be set to free wheel, so that the mobile base may be pushed or towed, without back driving the electric motor. The wheels may also be linked to the axle, so that the electric motor can provide torque to each of the wheels. The electric motors may be separately controlled to propel and steer the mobile base.
