Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling elements with sound-absorbing properties face limitations in integrating heating/cooling systems, compromising acoustic performance and visual aesthetics, while also being costly and difficult to install.
Innovation Solution
A ceiling element comprising two perforated panel elements with a groove in the rear of one panel for a heat transfer medium pipe, connected in a material-to-material and form-fitting manner, featuring a cavity in the second panel element to enhance sound absorption and stability, and optionally incorporating a textile layer for improved acoustic and visual concealment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pipeline for heating/cooling medium is integrated into the ceiling element, then heating/cooling capability is provided, but the acoustic effect is limited and visual appearance deteriorates due to visible pipes or shadows
Solution Approach 1:
The pipeline is extracted from the visible front side and relocated to the rear side of the first panel element, where it is concealed within the groove structure. This extraction removes the harmful visual effect (visible pipes/shadows) while preserving the heating/cooling function, and the sound-absorbing material in the groove further mitigates acoustic limitations.
Solution Approach 2:
The pipeline is nested within the groove structure of the first panel element, which itself is part of the larger ceiling element comprising multiple panels. This nested arrangement allows the pipeline to be concealed within the ceiling element's internal structure, eliminating visual defects while maintaining functionality.
2Adaptability or versatility
If a pipeline is integrated into the ceiling element, then heating/cooling capability is provided, but structural stability may be compromised
Solution Approach 1:
The groove containing the pipeline is localized to the rear side of the first panel element, leaving the front side and the connection between panels intact. This localized modification maintains the overall structural stability of the ceiling element while providing the necessary space for pipeline integration and heating/cooling functionality.
3Ease of manufacture
If the ceiling element uses a simple construction, then manufacturing cost is reduced, but sound-absorbing properties and heating/cooling integration are limited
Solution Approach 1:
The ceiling element is segmented into multiple functional components: first panel element with groove, second panel element with cavity, sound-absorbing material, and pipeline. This segmentation allows each component to be optimized for its specific function (sound absorption, structural stability, heating/cooling) while maintaining relative simplicity in manufacturing each individual component.
Solution Approach 2:
The ceiling element combines different materials and structures: perforated panel elements, sound-absorbing material, and integrated pipeline system. This composite construction achieves enhanced sound-absorbing properties and heating/cooling capability while keeping individual components manufacturable using standard techniques.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced sound absorption in the frequency range of 125 Hz to 8000 Hz, maintains structural stability, and integrates heating/cooling capabilities while being cost-effective and visually appealing, with improved acoustic and thermal performance.
Implementation Method 1
the groove is introduced into the front side of the second panel element in such a way that a cavity is formed in the second panel element, which cavity extends into the perforations of the second perforation pattern. Accordingly, the ceiling element according to the invention has a cavity above the pipeline, which in the second panel element as a so-called Helmholtz resonator provides an open space for the expansion of the sound waves, which contributes to improving the acoustic properties.
Implementation Method 2
ceiling element with sound-absorbing properties, which has a first panel element with a front side and a rear side
