Line Array Rigging Bar for Stable Splay Angle Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loudspeaker array systems face challenges in maintaining the splay angle between speakers, achieving rigid curvature, and efficient assembly, suspension, and transportation due to their non-rigid design and lack of dimensional considerations.
Innovation Solution
A suspension system utilizing a rigging bar with a pivotal member that extends along the side of the loudspeaker, allowing for secure coupling and adjustment of adjacent speakers, and featuring a quick release mechanism for easy assembly and disassembly, enabling the system to be easily transported and suspended while maintaining the desired curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional loudspeaker array systems are used, then assembly and installation can be performed, but the splay angle between speakers cannot be maintained constant and the system lacks rigidity when suspended
Solution Approach 1:
The system divides the loudspeaker array into modular segments with standardized rigging interfaces. Each loudspeaker or sub-array becomes an independent module that can be precisely positioned and then quickly connected to adjacent modules through the rigging bar system, maintaining angular relationships while simplifying assembly.
Solution Approach 2:
The patent replaces traditional mechanical angle-adjustment mechanisms with a geometry-based rigging system. By using rigid bars with fixed geometric relationships and pinned connections, the splay angles are determined by the physical dimensions of the rigging structure itself rather than adjustable mechanical components, providing inherent stability.
2Manufacturing precision
If elaborate preparation and labor are used to assemble and install multiple loudspeakers, then the desired configuration can be achieved, but installation time and cost become significant
Solution Approach 1:
The rigging bars and connection mechanisms are pre-configured with standardized geometries and attachment points during manufacturing. This preliminary preparation of the rigging structure eliminates the need for complex on-site measurements and adjustments, allowing installers to simply connect pre-fabricated modules in the desired configuration.
Solution Approach 2:
The system uses standardized dimensional parameters for rigging bars, connection points, and mounting holes. By fixing these geometric parameters during manufacturing rather than allowing field adjustment, the system achieves consistent configuration accuracy while dramatically reducing installation time through repeatable assembly procedures.
3Ease of manufacture
If line array loudspeaker systems are designed without dimensional considerations, then the systems can be manufactured, but transportation requires multiple vehicles and operation costs increase
Solution Approach 1:
The loudspeaker array system is divided into smaller modular segments that can be transported independently using fewer and smaller vehicles. The standardized rigging interfaces ensure that these segments can be quickly reassembled on-site to form the complete array, eliminating the need to transport entire large-scale configurations.
Solution Approach 2:
The modular design allows smaller loudspeaker modules to be nested or stacked within larger transport containers or onto flatbed vehicles in an space-efficient manner. The compact modular units can be arranged to maximize vehicle cargo space, reducing the number of transportation trips required.

AI summary
A system is provided for suspending a plurality of line array loudspeakers. The suspension system includes a rigging bar having an engaging member, such as a pivotal member, positioned near one end of the rigging bar. The engaging member includes a free end capable of extending outward past the end of the rigging bar in which the engaging member is positioned. The end of the rigging bar opposite the pivotal member is designed to releasably receive an engaging member of an adjacent rigging bar. The free end of the engaging member of the rigging bar may include a hole that aligns with holes positioned in the receiving end of the rigging bar. The engaging member of one rigging bar may then be secured to an adjacent rigging bar by aligning holes of the engaging member of a first rigging bar with the holes in the receiving end of a second rigging bar and inserting a release pin through the aligned holes.
