Solution Overview

Problem

Existing ventilation systems for stretch ceilings and suspended ceilings face issues with uneven air distribution, as air tends to stagnate in the center of larger rooms, and existing linear air diffusers are not compatible with stretch ceilings.

Innovation Solution

A perforated mounting profile connected to an air diffuser profile, featuring a double-chamber ventilation unit with an air flow regulator, slits, and a drop-shaped air deflector, which ensures uniform air distribution across the room by integrating with both stretch and suspended ceiling materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If air is supplied through a simple ventilation opening in the ceiling, then the installation is simple and compatible with stretch ceilings, but the air distribution becomes uneven with stagnation in the center of larger rooms

Engineering Contradiction:
Improveinstallation simplicityVSAvoidair distribution uniformity
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The ventilation system is segmented into multiple functional components: a mounting profile with air outlets distributed along its length, rather than a single central opening. This segmentation allows air to be supplied at multiple locations simultaneously, preventing stagnation in the room center and improving overall air distribution uniformity while maintaining installation simplicity through the modular profile design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ventilation system transitions from a point-source (single opening) to a line-source (distributed outlets along the profile). By extending the air supply across one dimension (along the ceiling perimeter), the system achieves better coverage of the room space without complicating the installation process.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If a linear air diffuser is integrated into a suspended ceiling, then air distribution can be improved, but it cannot be used with stretch ceilings

Engineering Contradiction:
Improveair distribution uniformityVSAvoidceiling type compatibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The mounting profile is designed with universal compatibility for both suspended ceilings and stretch ceilings. The profile includes attachment mechanisms that can accommodate different ceiling types, allowing the same air distribution system to be installed across various ceiling configurations. This multi-functionality resolves the contradiction by enabling improved air distribution while maintaining adaptability to different ceiling types.

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

Solution Approach 2:

The system allows for parameter changes in the mounting profile configuration to adapt to different ceiling types. The profile can be adjusted or selected in different versions suitable for suspended or stretch ceilings, while maintaining the core air distribution functionality. This flexibility enables the system to achieve good air distribution without being restricted to a single ceiling type.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If a complex air diffuser system with multiple components is installed, then air distribution uniformity improves, but the device complexity increases

Engineering Contradiction:
Improveair distribution uniformityVSAvoidnumber of components
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Multiple functions are merged into a single integrated mounting profile: air distribution outlets, structural support, attachment to ceiling, and integration with stretch/suspended ceiling materials. By combining these functions into one component rather than using separate parts, the system achieves improved air distribution uniformity while minimizing the number of components and simplifying installation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting profile serves multiple purposes simultaneously: it acts as the air distribution element, the structural support for the ceiling material, and the attachment mechanism. This multi-functionality reduces the overall device complexity by eliminating the need for separate components for each function, while still achieving the goal of uniform air distribution.

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

AI summary

A linear air diffuser for a suspended ceiling, which allows using a stretch ceiling material or any other suspended ceiling material or both simultaneously (installed on different sides of the profile) and also enables covering the point of connection of the mounting profile and stretch ceiling material or suspended ceiling material. The linear air diffuser also functions as a partition in a stretch ceiling.
