Acoustic Cell Floor Decoupling via Rubber Bearings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sound-decoupling technologies, such as sound-insulating mini boxes and conventional floor structures, fail to provide effective noise protection for spaces like examination rooms, acoustic specialist shops, and industrial production halls, and do not allow for the creation of large soundproof rooms that convey a sense of space, with inadequate sound insulation effects.
Innovation Solution
The use of shape-retaining soundproofing materials, like rubber bearings, as spacer elements between the floor structure and the cell-like space, combined with a multi-layered floor structure including a rigid gypsum fiber plate and insulating boards on cell walls, along with a metallic frame and carpet covering, to achieve acoustic decoupling from surrounding architectural components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sound-insulating mini boxes are used, then sound insulation is achieved, but the sense of space is lost
Solution Approach 1:
The invention implements a room-in-room configuration where a cell-like space (acoustic room) is nested within a larger building interior. The cell housing with its floor structure, walls, and ceiling creates an acoustic room that provides sound insulation while maintaining a sense of space through its larger volume and connection to the surrounding environment via door and window openings.
Solution Approach 2:
The invention transitions from small enclosed boxes to a spatial configuration where the acoustic room is defined by a cell housing with vertical walls and a ceiling, creating a three-dimensional space that provides both sound insulation and a sense of volume. The floor structure with spacer elements elevates the acoustic room floor above the building floor, adding vertical dimensionality.
2Strength
If conventional floor structures are used, then structural support is provided, but sound decoupling is insufficient
Solution Approach 1:
The invention introduces spacer elements made of sound-insulating material positioned between the building floor and the cell housing floor. These spacer elements act as intermediary components that provide both mechanical support for the floor structure and acoustic decoupling, preventing sound transmission through the floor while maintaining structural integrity.
Solution Approach 2:
The floor structure is constructed as a composite system combining the building floor, spacer elements made of sound-insulating material, and the cell housing floor. This composite structure integrates both structural support function and sound decoupling function within a single integrated assembly.
3Stability of the object's composition
If the acoustic room is connected to surrounding structures, then structural stability is maintained, but sound insulation deteriorates
Solution Approach 1:
The spacer elements serve as intermediary components between the building floor and the cell housing floor, providing both mechanical support for structural stability and acoustic decoupling for sound insulation. The sound-insulating material in the spacers breaks the direct structural connection for acoustic purposes while maintaining support.
Solution Approach 2:
The floor system is segmented into distinct components: the building floor, the spacer elements, and the cell housing floor. This segmentation allows the acoustic room to be structurally supported while acoustically isolated, as each segment serves specific functions that can be optimized independently.
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
This configuration significantly enhances soundproofing, creating a room-in-room system that is acoustically isolated from surrounding structures, allowing for the creation of noise-protected rooms in various settings, including medical, industrial, and residential environments.
Implementation Method 1
the floor area of the cell-like space separate from the building is separated in a sound-decoupling manner from a floor space of the building by at least one spacer element made of sound-insulating material(s)
Implementation Method 2
the floor structure should contain at least one plate made of gypsum fibers, which is also covered by a carpet-like covering, for the sake of sound throttling

AI summary
A building has an inner room where a further room of cell-like design is arranged. The floor structure (28) of the acoustic cell (20) is separated from the building and is set apart from a covering layer (12) using sound-isolating bearing members (30). A carpet covering (25a) terminates at the underside of a ceiling panel that spans the acoustic cell and bears on the walls (34,36).
