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 suspended, transported, and configured.
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
Solution Approach 1:
The system divides the loudspeaker array into modular segments with individual rigging bars for each speaker. Each rigging bar is an independent unit that can be precisely adjusted and locked, allowing the splay angle to be maintained constant while keeping the overall system manageable through modular construction rather than requiring a completely rigid monolithic structure.
Solution Approach 2:
The rigging bar incorporates movable components including a slide mechanism with locking capability. This allows the system to transition between adjustable states during installation and a locked rigid state during operation, maintaining constant splay angles while enabling initial configuration flexibility.
2Ease of manufacture
If conventional loudspeaker array systems are used, then speakers can be assembled, but substantial elaborate preparation and labor are required
Solution Approach 1:
The array is divided into modular loudspeaker units with integrated rigging bars that can be pre-assembled and tested independently. This segmentation allows parallel assembly operations and reduces on-site preparation requirements, as each module is self-contained and can be quickly connected to form the complete array.
Solution Approach 2:
The rigging bar serves multiple functions: it provides structural support, enables precise angle adjustment through its slide mechanism, and facilitates quick connection and disconnection. This multi-functionality consolidates what would otherwise require separate components and operations, reducing both preparation complexity and installation time.
3Ease of operation
If conventional loudspeaker array systems are used, then the system can be transported, but dimensional considerations are not optimized for efficient transportation
Solution Approach 1:
The loudspeaker array is divided into separate modular units that can be transported independently. Each unit has compact dimensions that optimize loading efficiency, and the modular nature allows flexible arrangement in transportation vehicles. The rigging bars and connecting mechanisms are designed to minimize overall volume while maintaining functionality.
4Manufacturing precision
If conventional loudspeaker array systems are used, then speakers can be arranged in a line array, but adjusting and maintaining the splay angle between adjacent speakers is difficult
Solution Approach 1:
The rigging bar incorporates a slide mechanism that allows the loudspeaker to be positioned at different angles during installation. Once the desired splay angle is achieved, the locking mechanism secures the position, maintaining precise angular relationships. This dynamic adjustment capability during assembly followed by rigid locking during operation resolves the contradiction between precision and ease of adjustment.

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.
