Solution Overview

Problem

Existing acoustic damping solutions for building elements, such as battens, are costly, labor-intensive, and complex, failing to effectively reduce noise transmission between building materials due to their multi-layered and complicated installations.

Innovation Solution

A composite acoustic damping batten comprising two resilient portions with different Shore hardness values, designed to securely attach building materials to structural substrates while minimizing sound transmission, using materials like elastomeric polymeric materials and expandable polymeric materials to absorb and dissipate sound energy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If multiple layers of acoustic damping material are used to reduce noise transmission, then acoustic performance is improved, but device complexity and installation difficulty increase

Engineering Contradiction:
Improvenoise transmissionVSAvoidassembly complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines the acoustic damping function with the structural batten function into a single integrated component. The batten incorporates resilient portions that directly contact both the structural substrate and the facing material, eliminating the need for separate acoustic damping layers while maintaining noise reduction performance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The batten serves multiple functions simultaneously: it provides structural support, acts as an acoustic damping element, and serves as a fixing point for facing materials. The resilient portions are configured to contact both the structural substrate and facing material, enabling the single component to perform what previously required multiple separate elements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If multiple layers of acoustic damping material are used to reduce noise transmission, then acoustic performance is improved, but installation time and labor requirements increase

Engineering Contradiction:
Improvenoise transmissionVSAvoidinstallation time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

By merging the acoustic damping function into the batten structure itself, the installation process is simplified to a single step rather than requiring multiple separate layers to be installed sequentially. The integrated design eliminates installation time associated with handling and positioning multiple separate damping materials.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If traditional acoustic damping materials are used between building materials, then noise transmission is reduced, but the system becomes costly and complicated

Engineering Contradiction:
Improvenoise transmissionVSAvoidassembly simplicity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The acoustic damping function is merged into the batten manufacturing process itself, creating a single integrated component that is easier to manufacture and install than multiple separate layers. The resilient portions are formed as part of the batten structure, eliminating the need for complex assembly operations.

Inventive Principle:
Principle #5Merging (Combining)

4Object-affected harmful factors

If resilient portions with different Shore hardness values are used, then acoustic damping performance is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvesound transmissionVSAvoidmaterial composition complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The batten is constructed from composite materials with different Shore hardness values in specific regions. The first resilient portion has a first Shore hardness value optimized for contacting the structural substrate, while the second resilient portion has a second Shore hardness value optimized for contacting the facing material, creating a composite structure that optimizes acoustic damping across different interfaces.

Inventive Principle:
Principle #40Composite materials
