Problem
Camera cranes and support vehicles face noise interference, significant maintenance, and environmental concerns due to the use of gasoline or diesel generators for electrical power, which are large, heavy, and consume fossil fuels.
Innovation Solution
A battery pack assembly with an AC to DC converter and lithium batteries providing 30 to 36 VDC power replaces the generator, offering a compact, lightweight, and maintainable solution for powering camera equipment, allowing for charging via wall current and eliminating the need for internal combustion engines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a gasoline or diesel generator is used to provide electrical power, then sufficient power can be generated, but noise interference occurs which interferes with filming
Solution Approach 1:
The patent replaces the mechanical internal combustion engine system with an electrical battery system. The battery pack assembly provides electrical power without any moving parts, combustion processes, or mechanical noise generation, thereby eliminating noise interference while maintaining sufficient power output for camera equipment.
Solution Approach 2:
The invention changes the fundamental operating parameters from combustion-based power generation to electrochemical energy storage and release. By using lithium batteries with AC to DC converters, the system transforms how power is generated and delivered, achieving silent operation while maintaining the required electrical power levels for hydraulic systems and camera equipment.
2Power
If a generator is used to provide electrical power, then power can be generated, but significant maintenance is required
Solution Approach 1:
The patent eliminates the complex mechanical systems of generators including engines, alternators, and cooling systems by replacing them with a solid-state battery system. Battery packs have no moving parts, require no fuel, and need minimal maintenance beyond periodic charging and replacement, dramatically improving ease of repair and reducing maintenance requirements.
3Power
If a generator is used to provide electrical power, then power can be generated, but environmental harm occurs due to fossil fuel consumption and exhaust emissions
Solution Approach 1:
The patent replaces fossil fuel-based combustion engines with electrochemical battery systems. This substitution eliminates exhaust emissions, carbon footprint, and environmental pollution entirely, as batteries store and release electrical energy without any combustion processes or harmful byproducts.
4Power
If a generator is used to provide electrical power, then sufficient power can be generated, but the device becomes large and heavy
Solution Approach 1:
The invention changes the power supply architecture from heavy mechanical generators to compact lithium battery packs with integrated AC to DC converters. Modern lithium batteries have high energy density, providing sufficient power for camera equipment while being significantly lighter and more compact than equivalent generator systems.

AI summary
A vehicle for carrying a camera crane has wheels or treads on a chassis. A battery pack assembly on the chassis, includes an AC to DC converter and plurality of batteries wired to a battery charger within a housing. The batteries collectively may have an output voltage of 30 to 36 VDC when fully charged. At least one input connector on the housing is wired to the AC to DC converter for charging the batteries. The battery pack assembly replaces and is used instead of a camera-equipment-generator.
