Solution Overview
Problem
Existing ceiling constructions struggle to simultaneously implement multiple functions such as heating/cooling, acoustic improvement, and fire protection while maintaining a low overall height, especially in public buildings with increased acoustic and fire safety requirements.
Innovation Solution
A multifunctional ceiling construction featuring heat-conducting profiles with a heat medium line, a ceiling panel, and sound absorber strips made of fire-retardant materials, which are designed to be attached to the ceiling with minimal visual impact and low surface weight, integrating heating/cooling functions and acoustic absorption without the need for additional layers or significant height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sound absorber panels are used to improve room acoustics, then acoustic effects are improved, but the arrangement of ceiling air conditioning elements becomes impossible
Solution Approach 1:
The ceiling is divided into modular elements: acoustic panels with integrated heating/cooling channels, support profiles with mounting surfaces, and separate air conditioning elements. This segmentation allows each component to fulfill its specific function while working together as a unified system, resolving the conflict between acoustic coverage and HVAC placement.
Solution Approach 2:
The acoustic panels are designed with integrated heating and cooling channels, making them multi-functional elements that simultaneously provide acoustic absorption and thermal regulation. This eliminates the need for separate HVAC infrastructure, allowing air conditioning elements to be arranged independently on the support profiles.
2Object-affected harmful factors
If the entire ceiling is covered with sound absorber panels, then good acoustic effects are achieved, but an arrangement of ceiling air conditioning elements is no longer possible
Solution Approach 1:
The ceiling system is segmented into acoustic panels that cover the entire ceiling area for optimal acoustic performance, while support profiles provide dedicated mounting locations for air conditioning elements. This segmentation allows full acoustic coverage without compromising HVAC accessibility.
Solution Approach 2:
The support profiles act as intermediary structures that bear the air conditioning elements, separating the acoustic function (performed by panels covering the entire ceiling) from the HVAC mounting function. This mediator allows both requirements to coexist without conflict.
3Object-affected harmful factors
If retrofitted soundproof ceilings are installed in existing rooms, then acoustic improvement is achieved, but technical and financial costs are high
Solution Approach 1:
The ceiling system consists of independent, pre-fabricated modular elements (acoustic panels, support profiles, mounting surfaces) that can be installed separately in existing rooms. This modular segmentation enables retrofitting without requiring complete ceiling demolition or complex structural modifications, reducing both technical difficulty and cost.
Solution Approach 2:
Instead of installing traditional soundproof ceilings that require building into the ceiling structure from above, this system attaches acoustic panels to the room side of existing ceilings using support profiles. This inverted approach allows acoustic improvement in existing rooms without accessing the building structure, significantly reducing retrofitting complexity and cost.
4Adaptability or versatility
If multiple functions are implemented on the ceiling, then optimized and variable use of space is achieved, but the overall height and structural demands increase
Solution Approach 1:
Multiple functions (acoustic absorption, heating, cooling) are merged into the same ceiling plane using thin, integrated components. The acoustic panels and HVAC elements are designed to work together within the same spatial envelope, eliminating the need for additional height layers and maintaining a low overall profile while delivering multiple benefits.

AI summary
The invention relates to a multifunctional ceiling construction, in particular for living spaces and workspaces (01). The ceiling construction has a plurality of heat-conducting profiles (14), which are fastened directly or indirectly to a building ceiling (11), and a downwardly directed mounting surface, wherein a line-receiving region (15) is formed in the mounting surface. Furthermore, a heat-medium line (16) is provided which runs in the line-receiving region (15) of the heat-conducting profiles (14) and channels a heat-transporting medium. A ceiling panel (17) is fastened to the mounting surface of the heat-conducting profiles (14) and is in heat-conducting contact with the heat-medium line (16). An absorber strip (03) composed of sound absorber elements extends along an upper abutment edge (02) which runs between a building wall (18) and the plane of the ceiling panel (17), wherein the sound absorber elements have a width of 200 - 400 mm, a thickness of 25 - 65 mm and a length-specific flow resistance in the range of 8 - 10 kPa*s/m4.
