Solution Overview
Problem
Existing soundproof enclosures are complex in design, difficult to assemble, disassemble, and relocate, and often compromise sound isolation due to air gaps, which also allow external air impurities to enter.
Innovation Solution
A modular soundproof enclosure system featuring interconnectable acoustical wall panels with a multilayer decoupling ceiling unit that provides filtered and silenced fresh air without the need for air ducts, and a floor base unit that allows easy relocation of the enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If mechanical ventilation with air ducts or hoses is used, then air circulation is improved, but construction complexity increases
Solution Approach 1:
The invention extracts and eliminates the complex air duct system from the enclosure design. Instead of using traditional air ducts or hoses for mechanical ventilation, the patent implements natural ventilation through strategically positioned air gaps and openings in the wall panels and ceiling, thereby simplifying construction while maintaining air circulation functionality
Solution Approach 2:
The enclosure utilizes natural convection currents and wind-driven airflow to achieve self-service ventilation. Air gaps in the walls and ceiling allow fresh air to enter and stale air to exit automatically without requiring mechanical fans, ducts, or hoses, thereby eliminating construction complexity while preserving air circulation
2Use of energy by moving object
If air gaps are created for natural ventilation, then air circulation is improved, but sound isolation deteriorates
Solution Approach 1:
The invention applies different properties to different parts of the enclosure structure. Air gaps for ventilation are created in non-critical areas where sound transmission is less problematic, while critical sound isolation zones use solid, gap-free construction. This localized differentiation allows natural ventilation through air gaps without significantly compromising overall sound isolation performance
Solution Approach 2:
The patent introduces sound-absorbing materials as intermediaries within and around the air gaps. These materials line the ventilation pathways and fill spaces between structural elements, allowing air to circulate freely while the sound-absorbing properties of the intermediary materials prevent noise transmission through the air gaps
3Use of energy by moving object
If air gaps are created for natural ventilation, then air circulation is improved, but air purity deteriorates due to external impurities
Solution Approach 1:
The invention performs preliminary action by incorporating air filtration systems that pre-clean incoming air before it enters the enclosure through the air gaps. Filters are installed at the air intake points in the wall panels and ceiling, removing external impurities and pollutants from the air stream before it circulates inside the enclosure, thereby maintaining air purity while preserving natural ventilation
4Ease of operation
If modular design is used for easy assembly and relocation, then ease of operation is improved, but structural integrity may deteriorate
Solution Approach 1:
The enclosure is divided into modular segments (wall panels, ceiling sections, floor base) that can be easily assembled and disassembled. Each module is designed with standardized connection interfaces featuring robust mechanical fastening systems, ensuring that while assembly is simplified through segmentation, the connection points maintain structural integrity through engineered joint strength
Solution Approach 2:
The wall panels and structural components utilize composite materials that combine rigidity and strength with manageable weight. These composite structures provide sufficient structural integrity to maintain enclosure stability while remaining light enough for easy handling, assembly, and relocation by a small team

AI summary
A method for building a soundproof enclosure in the form of an independent structure with acoustic properties for isolating noise and vibration is disclosed. The soundproof enclosure comprised a plurality of acoustical wall panels interconnectable each to another at opposing sides for enclosing an interior space of various sizes. It further comprised one or more modular multilayer ceiling unit(s) assembled onto the top edges of the wall panels. The ceiling unit comprised a plurality of ceiling layers, each ceiling layer being vertically spaced apart with one another by brackets to topographically form the multiple guided spaces necessary for air flow circulation. In addition, a construction method by elevating the wall panels and the ceiling units until they fall into precise assembly location for ease of assembly of the components and a floor base unit that enabled the enclosure to about easily in whole is also disclosed.
