Suspended Baffle System With Snap-Fit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspended baffle systems for sound control in open plenum building spaces often require custom design, new tooling, and unfamiliar construction techniques, leading to increased labor costs and resistance from contractors due to their novelty.
Innovation Solution
A suspended baffle system utilizing existing linear ceiling technology with hollow sheet metal baffles that snap into elongated carriers, featuring a self-aligning mounting flange structure and hidden sheet metal clips for secure installation, leveraging familiar components for both sound control and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom designed baffle systems with new components are used, then sound control performance is improved, but manufacturing complexity and labor costs increase
Solution Approach 1:
The baffle system utilizes existing linear ceiling carrier components that serve dual purposes: their original structural function and a new function as mounting mechanisms for acoustic baffles. The carrier's grip elements, originally designed for ceiling tiles, are adapted to engage with baffle mounting flanges, eliminating the need for custom-designed mounting hardware and reducing manufacturing complexity.
Solution Approach 2:
The mounting flange structure incorporates self-aligning features with guide edges that automatically position the baffle correctly on the carrier during installation. The snap-fit engagement mechanism provides self-locking functionality, eliminating the need for additional fastening operations or specialized installation tools, thereby reducing labor costs.
2Reliability
If new construction and assembly techniques are introduced, then sound control effectiveness is improved, but labor costs and installer resistance increase
Solution Approach 1:
The baffle mounting system maintains visual and structural homogeneity with existing linear ceiling installations. The carriers, grips, and mounting flanges all follow the same design language and installation patterns as traditional ceiling systems, allowing installers to apply their existing skills and techniques without requiring retraining or encountering resistance.
Solution Approach 2:
The system replaces complex mechanical fastening operations with a simplified snap-fit engagement mechanism. The mounting flange's flexible lip simply snaps into the carrier grip and locks in place, eliminating the need for screws, nails, or other traditional fastening methods that require specialized tools and techniques.
3Stability of the object's composition
If deep section baffles are used to rigidify the carrier grid, then structural stability is improved, but material usage and manufacturing complexity increase
Solution Approach 1:
The system creates a composite structural system where the deep-section baffle acts as a structural reinforcement element integrated with the carrier grid. The baffle's deep section, originally intended for acoustic purposes, serves dual functions: providing sound absorption and acting as a torsion element that rigidifies the carrier grid, thereby reducing the need for additional structural support materials.

AI summary
An acoustical baffle system for suspension in an open plenum space comprising a plurality of parallel spaced carriers and a plurality of parallel spaced baffles suspended on and transverse to the carriers, the carriers having pairs of opposed, uniformly spaced grips on their lower faces, pairs of opposed grips being spaced along the carrier at a regular center-to-center distance greater than the spacing between a pair of opposed grips, the baffles having a relatively deep U-shaped cross-section with sides and a bottom between the sides, outwardly directed flanges at upper ends of the sides, the flanges being received in a respective pair of grips on each of a plurality of carriers.
