Solution Overview
Problem
Conventional acoustic ceiling decks lack the ability to be dynamically tuned for optimal sound absorption and reflection, limiting their flexibility in achieving desired sound effects in various environments.
Innovation Solution
A tunable acoustic deck system featuring a rotatable and translatable insert within a deck member, which adjusts acoustic properties by altering the exposure of sound absorption and reflection surfaces, allowing for customizable sound effects through motorized control and multiple positional settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional acoustic ceiling decks use fixed sound absorption materials, then sound absorption is consistent, but the ability to adapt to different acoustic environments is limited
Solution Approach 1:
The patent applies the dynamics principle by making the insert movable within the deck member cavity. The insert can be positioned at different locations (front, center, back) along the acoustic axis, allowing the acoustic deck to dynamically adjust its sound absorption and reflection characteristics based on different acoustic environment requirements
Solution Approach 2:
The patent segments the acoustic deck into a stationary deck member and a movable insert component. This segmentation allows independent optimization of each part and enables the insert to be repositioned or removed to achieve different acoustic configurations
2Manufacturing precision
If acoustic decks use fixed profile design, then manufacturing is simplified, but tuning capability for desired sound effects is lost
Solution Approach 1:
The movable insert provides dynamic tuning capability without requiring complex manufacturing. The insert is a simple component that can be manufactured separately and then installed in the deck member, maintaining manufacturing simplicity while enabling precise acoustic property adjustment through repositioning
3Reliability
If acoustic decks use sound absorbing materials, then reverberation is reduced, but specular reflection capability is limited
Solution Approach 1:
The patent applies local quality by providing different acoustic treatments on different parts of the insert. The insert can have sound absorbing materials on certain surfaces and reflective surfaces on other surfaces, allowing simultaneous optimization of both sound absorption and specular reflection properties in different directions
Solution Approach 2:
By repositioning the insert within the cavity, the deck can dynamically adjust the balance between sound absorption and specular reflection. When the insert is positioned to expose absorbing surfaces, reverberation is reduced; when positioned to expose reflective surfaces, specular reflection is enhanced

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise tuning of acoustic properties to achieve desired sound effects, enhancing both sound absorption and reflection characteristics, thereby improving sound quality and flexibility in different acoustic environments.
Implementation Method 1
The deck member can include a seal proximate the opening, whereby when the seal is in contact with the tunable insert, sound waves that pass proximate the contact point of the seal and the tunable insert are affected
Implementation Method 2
The acoustic absorption material can be positioned between the stationary insert and the base
