Solution Overview

Problem

Existing panels used in buildings with thermally activated building systems (TABS) face challenges in balancing acoustics and thermal comfort, as they often have suboptimal thermal properties despite good acoustic regulation.

Innovation Solution

The development of panels with 'Thermal Transparency' technology, featuring a rigid frame, sound-absorbing elements with exposed side faces for increased absorption, and a flexible fabric covering, which allows for thermal radiation transmission without compromising acoustic performance, and can be easily installed, reconfigured, and maintained.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If panels use sound-absorbing materials such as mineral wool, gypsum or thin wood membrane, then acoustic properties are improved, but thermal properties deteriorate

Engineering Contradiction:
Improveacoustic propertiesVSAvoidthermal properties
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The panel employs different materials and structures in different regions: sound-absorbing materials are placed in specific zones while thermal-transparent regions are created to allow heat transmission. This local differentiation enables the panel to simultaneously achieve acoustic absorption in certain areas and thermal transmission in others, resolving the contradiction between acoustic and thermal properties.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The panel is divided into distinct functional zones: sound-absorbing elements are segmented and positioned within a frame structure that includes thermal-transparent regions. This segmentation allows independent optimization of acoustic and thermal functions in different parts of the same panel, enabling both properties to be satisfied simultaneously.

Inventive Principle:
Principle #1Segmentation

2Temperature

If panels are designed for optimal thermal transparency, then thermal properties are improved, but acoustic properties deteriorate

Engineering Contradiction:
Improvethermal transparencyVSAvoidacoustic properties
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The panel structure incorporates localized sound-absorbing elements positioned within thermal-transparent regions. The sound-absorbing materials are strategically placed to capture acoustic energy while maintaining overall thermal transparency through the panel structure, allowing both functions to coexist without compromising either property.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The frame structure acts as an intermediary element that supports sound-absorbing materials while maintaining thermal transparency. The frame provides structural integrity and positions acoustic elements effectively without blocking thermal transmission paths, mediating between acoustic and thermal requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention relates to panels that can be used to cover interior surfaces in buildings, for instance in auditoriums, open-plan offices etc., where the panels can be used in buildings with thermally activated building systems (TABS) in which balancing of acoustics and thermal comfort is a well-recognised challenge. According to the invention there is provided a panel comprising one or more sound-absorbing elements (3) and sub-regions (7, 8, 9) that connect the front (11) of the panel with the rear (12) of the panel, and in which sub-regions (7, 8, 9) sound-absorbing elements (3) are not present, whereby said sub-regions (7, 8, 9) ensure thermal transmission through the panel.
