Solution Overview

Problem

Existing partition systems for dividing spaces in buildings suffer from limited soundproofing performance, failing to provide adequate sound insulation between rooms.

Innovation Solution

A partition system comprising a frame made of thermoplastic polyolefin mixture-based perimetric profiles and acrylonitrile butadiene styrene (ABS)-based covering profiles, with glass or other materials for panels, featuring snap joints and modular design to enhance soundproofing and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional masonry or plasterboard walls are used for partition systems, then structural strength and stability are ensured, but soundproofing performance remains limited

Engineering Contradiction:
Improvesoundproofing performanceVSAvoidpartition system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The partition panel uses a composite structure combining a rigid frame (aluminum or steel) with sound-absorbing insulation material (mineral wool, foam, or acoustic panels) filled inside, creating a multi-layer composite wall system that achieves superior soundproofing while maintaining structural integrity

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The partition panel employs a nested structure where the sound-absorbing material is placed inside the frame, creating concentric layers that trap and absorb sound waves, thereby enhancing soundproofing performance without significantly increasing overall wall thickness

Inventive Principle:
Principle #7Nested doll (Nesting)

2Illumination intensity

If glazed partition panels are used to allow light diffusion, then rooms become brighter, but soundproofing performance deteriorates

Engineering Contradiction:
Improvelight diffusionVSAvoidsound insulation
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The partition system uses different materials for different functions: the frame and insulation layers are optimized for soundproofing, while specific glazed sections are strategically placed to provide light diffusion, creating local variations in material properties that satisfy both requirements simultaneously

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The partition panel is segmented into multiple functional zones: solid frame sections for structural support and soundproofing, and glazed insert sections for light transmission, allowing the system to deliver both sound insulation and natural lighting benefits

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If modular partition systems with frames and panels are used for easy assembly, then installation flexibility is improved, but soundproofing performance becomes insufficient

Engineering Contradiction:
Improveassembly flexibilityVSAvoidsound insulation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The modular partition system divides the wall into standardized panels that can be easily assembled and disassembled, while each panel internally contains sound-absorbing materials and sealed joints that maintain effective sound insulation despite the modular construction approach

Inventive Principle:
Principle #1Segmentation

AI summary

A partition system (10) for dividing a space, comprising a frame (11) and one or more partition panels (12) mountable on the frame, wherein the frame comprises a plurality of main profiles (100) which comprises at least one plurality of perimetric profiles (110) configured to be fixed to a surface of the space; one or more perimetric profiles are constituted of a main material which is thermoplastic polyolefin mixture-based. Each main profile delimits a first front hollow (102) which, in use, receives an edge (13) of at least one of the partition panels. The frame comprises a plurality of covering profiles (200) which are couplable by means of a snap joint to the plurality of main profiles, and which comprises a plurality of first covers (201) couplable in such a way as to close the first front hollow at the first lateral side obstructing removal of the partition panel.
