Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound reduction panels lack waterproofing and decorative options while maintaining effective sound reduction properties without increasing cost or weight.
Innovation Solution
A water-resistant sound reducing panel is designed with a front porous sheet, a fiber glass fiber board sound absorbing member, a polymeric sound blocking member, and an aerogel decoupling member, which includes a drenching shield for waterproofing and a decorative or artistic image for aesthetic appeal, while using an aerogel material to reduce sonic vibration and insulate from fire or heat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drenching shield is added to provide waterproofing, then water resistance is improved, but device complexity increases
Solution Approach 1:
The drenching shield is integrated within the existing panel structure, nesting the waterproofing function inside the panel assembly rather than adding an external separate system. This allows waterproofing without proportionally increasing overall complexity.
Solution Approach 2:
The drenching shield utilizes a thin film or shell structure that provides waterproofing with minimal added bulk and complexity. This flexible approach allows integration without requiring heavy or complex rigid waterproofing systems.
2Reliability
If aerogel material is used for decoupling, then sound reduction is improved, but weight increases
Solution Approach 1:
The patent changes the density parameter of the decoupling material by using aerogel, which has extremely low density compared to traditional materials. This allows achieving superior sound reduction properties while minimizing weight increase.
Solution Approach 2:
The panel uses composite material construction, combining aerogel with other panel components to create a multi-functional assembly that provides both sound reduction and structural integrity without excessive weight.
3Reliability
If multiple layers are added for sound blocking, then sound transmission coefficient is improved, but device complexity increases
Solution Approach 1:
The sound reduction function is segmented into multiple specialized layers (sound absorbing member, sound blocking member, aerogel decoupling layer) rather than using a single thick barrier. This segmentation allows each layer to be optimized for its specific function while maintaining overall system manageability.
Solution Approach 2:
The panel employs composite material construction with multiple layers having different acoustic properties. This composite approach achieves superior sound transmission coefficient by combining the effects of different materials rather than relying on a single complex structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The panel achieves enhanced sound reduction with improved waterproofing and decorative capabilities, maintaining effectiveness in various environments without significant weight or cost increases, offering improved sound transmission coefficient (STC) and fire resistance.
Implementation Method 1
An aerogel material decoupling member reduces sonic vibration from being transferred from the sound blocking member to the rear non-porous sheet
Implementation Method 2
An aerogel material decoupling member reduces sonic vibration from being transferred from the sound blocking member to the rear non-porous sheet. The sound blocking member is interposed between the fiber glass fiber board sound absorbing member and the aerogel material decoupling member for insulating the sound blocking member from fire or excessive heat.
Implementation Method 3
A drenching shield inhibits water from entering the water resistant sound absorbing member
Implementation Method 4
A fiber glass fiber board sound absorbing member is located adjacent to the front porous sheet for dissipating sound entering into the front porous sheet
Implementation Method 5
A sound blocking member comprises a sheet of polymeric material having a weight equal to or greater than one pound per square foot located adjacent to the sound absorbing member for blocking sound propagating through the sound absorbing member

AI summary
An improved sound reducing panel is disclosed comprising a front porous sheet for enabling sound to enter into the sound reducing panel and a rear non-porous sheet. A sound absorbing member dissipates sound entering into the front porous sheet. A sound blocking member blocks sound from exiting from the sound absorbing member. A decoupling member reduces sonic vibration from being transferred from the sound blocking member to the rear non-porous sheet. One embodiment includes a drenching shield for inhibiting water from entering the sound absorbing member. Another embodiment includes a decorative or artistic image located on the sound reducing panel.
