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 locations where space and stability are crucial.
Innovation Solution
A camera crane mobile base with a rectangular chassis equipped with drive motor assemblies at each corner, a pivotable column for lateral and longitudinal movement, and a telescoping crane arm, allowing for multiple steering modes and easy disassembly for indoor transport, featuring a steering system and actuators for stability and maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mobile base is designed to carry larger crane arms, then the load capacity and stability are improved, but the size and weight of the base increase, making it harder to transport and maneuver
Solution Approach 1:
The mobile base is divided into modular components including a chassis, column assembly, and crane arm sections that can be independently assembled and disassembled. This segmentation allows the base to be configured for heavy load capacity when needed and easily disassembled for transport when maneuverability is required.
Solution Approach 2:
The base incorporates movable and adjustable components such as the pivotable column, telescoping crane arm sections, and removable drive motor assemblies. These dynamic elements allow the structure to adapt between a stable, expanded configuration for supporting heavy crane arms and a compact, disassembled state for easy transport through standard doorways.
2Ease of operation
If the mobile base is designed to be compact for transport, then the ease of transportation is improved, but the stability and rigidity of the platform are reduced
Solution Approach 1:
The base is designed as a segmented system with a rigid chassis that provides a stable foundation when assembled. The modular nature allows the stable platform to be easily disassembled into transportable sections, resolving the contradiction between compactness for transport and stability when deployed.
Solution Approach 2:
The base incorporates pre-assembled rigid components such as the chassis frame and column assembly that provide inherent stability when put together. These pre-engineered stable structures can be quickly assembled and disassembled, allowing the platform to achieve stable configuration before use and return to compact form after use without compromising either transportation ease or platform stability.
3Adaptability or versatility
If the crane arm is made telescoping and extendable, then the versatility and range of camera positions are improved, but the complexity of the structure increases
Solution Approach 1:
The telescoping crane arm is divided into multiple extendable sections that can be independently adjusted. This segmentation provides versatile camera positioning capabilities while allowing each section to be relatively simple in design, and the entire arm to be disassembled for transport, managing the complexity through modular construction.

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 one or more wheels attached to the axle. The electric motors may be separately controlled to propel and steer the mobile base. A column is pivotally attached to the chassis and pivotal in lateral and longitudinal directions via actuators. The drive motor assemblies may be removed from the chassis for storage or transport. With the drive motor assemblies installed, the mobile base is highly stable and maneuverable. With the drive motor assemblies removed, the chassis is narrow enough to fit through a typical doorway.
