Telescoping Light Tower Boom Stability and Wind Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high-intensity mobile lighting systems face challenges in covering large areas effectively due to limited height and stability issues, particularly with towers over 80' or 100' which are cumbersome, prone to wind damage, and require multiple units, increasing complexity and cost.
Innovation Solution
A telescoping light tower with multiple nested boom sections and safety features such as wind sensors and locking mechanisms to secure and retract the boom, allowing for extended heights while minimizing wind impact and ensuring stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the boom is extended to 80' or 100' or more to light larger areas, then the lighting coverage area increases, but the tower becomes unwieldy and difficult to move when vertical
Solution Approach 1:
The patent employs a telescoping boom structure where multiple boom sections are nested within each other. The inner boom sections are housed inside outer boom sections, allowing the entire 80'-100' boom to collapse into a compact configuration for transport. This nesting principle enables the boom to achieve its full extended length for lighting coverage while maintaining a compact stowed size for mobility.
2Area of stationary object
If the tower height is increased to 80' or 100' or more to cover larger areas, then the lighting capacity improves, but wind forces create extremely large torque at the base
Solution Approach 1:
The telescoping boom structure reduces the tower's profile when retracted, minimizing the sail area exposed to wind forces during transport and storage. This allows the same boom to provide extensive lighting coverage when extended while presenting a minimal wind resistance profile when collapsed.
Solution Approach 2:
The boom transitions between static extended and retracted positions, dynamically adjusting its configuration based on operational needs. When extended, it provides maximum lighting coverage; when retracted, it minimizes wind exposure. This dynamic reconfiguration allows the system to optimize performance while mitigating wind torque hazards.
3Area of stationary object
If multiple lighting units are deployed to cover larger areas, then the lighting coverage increases, but the operational complexity and cost increase
Solution Approach 1:
The boom is divided into multiple telescoping sections that can be independently controlled. This segmentation allows the boom to be extended to great heights (80'-100'+) with a single unified structure, providing lighting coverage that would otherwise require multiple separate towers. The segmented design maintains structural integrity while achieving the height and coverage of multiple units.
4Volume of moving object
If the boom is kept in horizontal position during transport, then the tower is more compact, but it requires additional structure to support the extended boom
Solution Approach 1:
The telescoping boom sections nest within each other when retracted, creating a compact cylindrical package that minimizes storage volume. This nested configuration eliminates the need for extensive external support structures during transport, as the boom self-supports in its collapsed state. The same nested structure allows the boom to extend to full length when needed, providing the dual benefit of compact storage and full operational capability.

AI summary
A mobile lighting device is disclosed with extendable boom sections. The boom sections are stored in a horizontal position and then pivot to a vertical position before being extended upward. A light section is positioned at the uppermost end of the last extendable boom section. A variety of safety features are also disclosed.
