Acoustic Formwork Wall with Integrated Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current walls with integrated acoustic formwork face challenges such as extended manufacturing and installation times, complexity in covering acoustic insulation, incomplete noise attenuation, high costs, and susceptibility to degradation, especially when acoustic insulation is added to either skin during manufacturing or on-site installation.
Innovation Solution
Incorporating an intermediate element between the first and second skins with primary and secondary through openings that allow acoustic insulation to be positioned inside the wall, enabling direct sound wave attenuation and using materials like mineral wool, vegetable wool, or powdery materials for improved acoustic performance and potential greening benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acoustic insulation means are fixed on the first skin or second skin during manufacturing or on-site installation, then acoustic performance is improved, but manufacturing time and installation time are extended
Solution Approach 1:
The patent merges the acoustic insulation function directly into the wall structure by positioning acoustic insulation means within the internal volume formed between the first and second skins. This integration eliminates the need for separate fixation steps on external surfaces, thereby improving acoustic performance while avoiding extension of manufacturing or installation time.
Solution Approach 2:
The acoustic insulation means are positioned within the internal volume during the manufacturing process itself, before the wall is installed on-site. This preliminary placement ensures acoustic performance is built-in from the start, eliminating subsequent installation steps and reducing overall time loss.
2Object-affected harmful factors
If acoustic insulation means are fixed on the first skin facing the exterior, then noise pollution reduction is improved, but cladding and covering complexity is significantly increased
Solution Approach 1:
The patent moves the acoustic insulation means from the external surface (first skin) to the internal volume between the first and second skins. This dimensional relocation places the insulation in three-dimensional space within the wall structure, effectively reducing noise pollution while avoiding complications with external cladding and covering.
3Object-affected harmful factors
If acoustic insulation means are fixed on the second skin facing the interior, then partial noise attenuation is achieved, but noise transmitted through the first skin to structural elements remains unattenuated
Solution Approach 1:
The patent uses the internal volume between the first and second skins as an intermediary space to position the acoustic insulation means. This intermediate positioning allows the insulation to intercept sound waves before they transmit through either skin to structural elements, achieving more complete noise attenuation compared to placement on just one surface.
4Reliability
If acoustic insulation means are used for noise attenuation, then acoustic performance is improved, but cost is significantly increased and susceptibility to degradation is high
Solution Approach 1:
The patent employs cost-effective acoustic insulation materials such as mineral wool, vegetable wool, or powdery materials that can be easily positioned within the internal volume. These materials provide effective acoustic performance at lower cost compared to traditional fixed insulation solutions, and their placement within the protected internal volume reduces susceptibility to degradation from environmental exposure.
