Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rigging systems for loudspeaker arrays face challenges in safety, precision, and efficiency during assembly and disassembly, particularly due to the heavy weight and complexity of the systems, which leads to hazards such as pinching injuries and time-consuming adjustments, especially when forming curved arrays or transporting and stacking array elements.
Innovation Solution
The development of rigging components with a slidably extendable connection link and a latching device that includes a spring-biased retention device to securely connect array elements, allowing for quick and precise angular adjustments and assembly, reducing the need for manual insertion of structural pins and minimizing the risk of accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rigging systems with structural pins and locking mechanisms are used, then connection strength and safety are improved, but device complexity and assembly time increase
Solution Approach 1:
The patent changes the fundamental parameter of connection mechanism from manual pin insertion to spring-loaded automatic locking. The spring force parameter enables automatic engagement when array elements are brought together, eliminating the need for complex manual locking procedures while maintaining secure connections.
Solution Approach 2:
The rigging system performs self-service through automatic locking mechanisms. When array elements are positioned together, the spring-loaded pins automatically extend and lock the elements in place without requiring manual intervention. This self-service capability reduces complexity while maintaining reliability.
2Reliability
If manual pin insertion methods are used for connecting array elements, then connection reliability is improved, but assembly speed and operational efficiency deteriorate
Solution Approach 1:
The spring-loaded pins are pre-compressed and stored in a retracted position within the rigging component. When array elements are brought together, the pre-stored spring energy automatically propels the pins into the locking position, performing the connection action preliminarily prepared without requiring manual effort during assembly.
Solution Approach 2:
The patent replaces the manual mechanical pin insertion system with an automated spring-loaded mechanism. The spring force substitutes for human manual insertion, automatically driving the pins into place and securing the connection, thereby significantly increasing assembly speed while maintaining reliability.
3Reliability
If heavy duty rigging components with high safety factors are used, then structural safety is improved, but weight of the system increases
Solution Approach 1:
The patent introduces dynamic elements to the rigging system through spring-loaded pins that can extend and retract. This dynamic mechanism allows the system to maintain high safety factors when needed while reducing weight compared to continuously heavy-duty rigid components, as the springs provide strength only when engaged during connection.
Solution Approach 2:
The rigging system is segmented into modular components with spring-loaded pins that can be independently engaged. This segmentation allows each component to be optimized for its specific function, using spring mechanisms only where connection is needed, thereby reducing overall system weight while maintaining structural safety through targeted reinforcement.
4Adaptability or versatility
If adjustable rigging components are used for curved arrays, then adaptability is improved, but device complexity and adjustment time increase
Solution Approach 1:
The adjustable rigging components perform self-service through automatic locking mechanisms that secure the array elements at their desired angles without requiring manual adjustment or complex locking procedures. The spring-loaded pins automatically engage to maintain the configured angle, reducing the complexity of adjustment operations.
Solution Approach 2:
The patent employs parameter changes in the adjustable components, allowing the rigging system to adapt to different array configurations by changing the engagement position of the spring-loaded pins. This enables flexible curved array formation while maintaining relatively simple component design, as the same basic mechanism adapts to multiple configurations.

AI summary
Disclosed herein is a rigging component for connecting a loudspeaker array element in an array. The rigging component is configured for releasably attaching one array element to another array element via a connection link that is slidably extendable from a housing. The housing includes a conduit for receiving a connection link of an adjacent rigging component. A latching device is provided for retaining the connection link of the adjacent rigging component within the conduit. An additional latching device may be included for releasably locking the connection link of the rigging component at one or more positions for controlling a relative separation of adjacent array elements.
