Line Array Rigging Adaptor for Infinite Pan and Tilt Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional line array mounting frames lack infinite adjustability for pan and tilt control, making it difficult to alter the orientation of a line array while it is under load, as support points only allow for standard increments or no adjustments at all.
Innovation Solution
A specially designed adaptor with infinitely adjustable tilt controls, featuring a main frame with longitudinally extending rods and attachment members that allow for precise positioning and adjustment of the line array's pan and tilt, using bolts and engagement members to secure and move the attachment members relative to the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional frames with fixed support points are used, then the structure is simple and stable, but the adaptability for pan and tilt control is limited
Solution Approach 1:
The frame is divided into modular components including adjustable support points with standardized interfaces. Each support point can be independently positioned along the frame members, allowing flexible configuration without redesigning the entire structure. This segmentation enables adaptability while maintaining structural simplicity through standardized modular elements.
Solution Approach 2:
The frame design incorporates universal support points that can serve multiple functions - providing both structural support and adjustable pan/tilt control. The standardized interfaces allow the same frame structure to accommodate different line array configurations and adjustment requirements, making the frame multi-functional without increasing complexity.
2Adaptability or versatility
If support points are made adjustable for pan and tilt control, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The support points are designed with dynamic adjustment capabilities, allowing users to reposition them along the frame members as needed. The adjustment mechanisms use simple movable components with locking features, enabling the support points to transition between fixed and adjustable states. This dynamic design provides adaptability while keeping the adjustment mechanism relatively simple through straightforward mechanical movements.
Solution Approach 2:
The adjustability is achieved by changing the positional parameters of support points along the frame members. By allowing continuous or incremental movement of support points to different locations, the system achieves high adaptability for pan and tilt control. The parameter changes are implemented through simple mechanical adjustment rather than complex mechanisms, maintaining ease of use.
3Measurement precision
If standard increment adjustments are used, then the device complexity is low, but the measurement precision for pan and tilt control is insufficient

AI summary
A rigging system adaptor which creates an infinite number of adjustability positions for a line array, wherein the adaptor is particularly well suited for use with a spine frame. The adaptor comprises a main frame having a longitudinally extending body to which a first attachment member, a second attachment member, and a mount are attached. The first attachment member may be fixed onto the main frame via a pair of lateral rods, wherein the lateral rods are oppositely situated from each other relative to the main frame. The second attachment member and the mount may be slidably engaged with the lateral rods such that they can move along the main frame and can be repositioned to meet the specific needs of a user.
