PET Acoustic Panel Suspension for Full Recyclability

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing acoustic elements, particularly those made of PET, are difficult to recycle due to the use of metal components and adhesives, which contaminate the PET material and require labor-intensive disassembly.

Innovation Solution

The use of PET clips and connectors to assemble acoustic elements, allowing for the entire product to be recycled without disassembly, using a suspension system that eliminates the need for additional bracing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If metal components and adhesives are used to attach PET acoustic elements to walls or ceilings, then the acoustic elements can be securely fixed and provide good sound absorption properties, but the PET material becomes contaminated and cannot be readily recycled without labor-intensive cutting or removal of non-PET components

Engineering Contradiction:

Improvesecure fixationVSAvoidrecyclability

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The invention extracts and removes metal components and adhesives from the assembly system, replacing them with PET-compatible mechanical fixing methods such as clips, channels, and interlocking features that can be easily separated from the PET acoustic elements for recycling

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the material parameter of the fixing components from metal to PET or other recyclable materials, and changes the bonding mechanism from adhesive bonding to mechanical interlocking, enabling easy separation and recycling of the PET acoustic elements

Inventive Principle:

Principle #35Parameter changes

2Strength

If adhesive is used to secure PET acoustic components, then strong bonding is achieved, but the PET material becomes unable to be recycled as the adhesive does not comply with recycling standards

Engineering Contradiction:

Improvebonding strengthVSAvoidrecyclability

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The invention replaces the chemical bonding mechanism (adhesive) with a mechanical bonding system using clips, channels, and interlocking features, maintaining strong fixation while enabling easy separation and recycling of the PET acoustic elements without contamination

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If suspended ceiling systems are designed with additional bracing for earthquake prone areas, then structural stability is improved, but the system becomes more labor intensive and time consuming to assemble

Engineering Contradiction:

Improvestructural stabilityVSAvoidassembly speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The invention merges the bracing function into the primary suspension components themselves, where the suspension clips and connectors are designed to provide both hanging and bracing functions simultaneously, eliminating the need for separate bracing components and reducing assembly steps

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention makes the suspension components multi-functional, allowing the same clips and connectors to provide both vertical suspension and lateral bracing stability, thereby improving structural reliability without adding additional components or assembly steps

Inventive Principle:

Principle #6Universality (Multi-functionality)
