Solution Overview

Problem

Existing air diffuser and plenum installations on walls are burdensome, prone to cracking, and aesthetically unsatisfactory, often leading to mold formation.

Innovation Solution

A monobloc plenum-linear diffuser assembly that integrates a plenum and diffuser as a single piece, concealed within a wall, using a polymeric material with insulating and sound-absorbing properties, and secured with a mesh element embedded in the wall for stable fixation, preventing cracks and mold.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If separate plenum and diffuser components are installed on the wall, then air distribution function is achieved, but installation complexity and time increase

Engineering Contradiction:

Improveinstallation speedVSAvoidassembly complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the plenum and diffuser into a single integrated monobloc component, eliminating the need for separate assembly and installation of multiple parts. This merging reduces installation time and complexity while maintaining the air distribution function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The monobloc component serves multiple functions simultaneously: it acts as both the plenum (air distribution chamber) and the diffuser (air outlet structure), and also provides its own mounting functionality through integrated fixation elements, reducing the need for separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate plenum and diffuser components are fixed to the wall, then air distribution is achieved, but cracks form between components and wall

Engineering Contradiction:

Improvefixation stabilityVSAvoidcrack formation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By merging the plenum and diffuser into a single monobloc component, the patent eliminates the gaps and joints between separate components that would otherwise create cracks. The integrated structure provides continuous surface contact with the wall, preventing crack formation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The monobloc component features localized fixation elements (such as mounting flanges or integration with the mesh element) that concentrate the fixation function at specific points, ensuring stable attachment to the wall while maintaining a crack-free surface across the entire component.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If separate plenum and diffuser components are installed, then air distribution function is achieved, but aesthetic appearance deteriorates due to visible cracks

Engineering Contradiction:

Improveinstallation simplicityVSAvoidaesthetic appearance

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The integrated monobloc design eliminates visible cracks and joints between components, providing a smooth, continuous surface that maintains aesthetic appearance. The single-piece construction ensures uniform geometry and seamless integration with the wall and mesh element.

Inventive Principle:

Principle #5Merging (Combining)

4Ease of manufacture

If traditional separate components are used, then installation is performed, but mold formation occurs in cracks

Engineering Contradiction:

Improvemanufacturing costVSAvoidmold formation

Core Design Contradiction:

Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

By eliminating cracks through the monobloc design, the patent removes the harbors where mold would otherwise form. The continuous surface without joints or gaps prevents moisture accumulation and biological contamination, ensuring hygienic operation.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A monobloc plenum - linear diffuser assembly which can be fixed to a wall (P) at a specific housing (A) obtained therein, for example a plasterboard or masonry wall of a ceiling or false ceiling, for distributing air between a central air distribution unit and a space of interest, comprising an air distribution plenum (2) which can be fluidically connected with the central air distribution unit and comprising a substantially elongated main collector structure (20) which can be concealingly inserted into the wall (P), with an internal cavity (22). The assembly further includes a linear diffuser (1) comprising an elongated hollow body (10) defining an axis (X) with at least one slot (14) extending along the latter which can be positioned at the specific housing (A), configured to place in fluidic communication the internal cavity (22) and the space of interest.
