Prefabricated Noise Abatement Wall Assembly for Mechanical Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noise abatement wall systems require significant on-site construction effort, as they often need separate foundations or buried support posts, making it cumbersome to assemble around noise-generating mechanical equipment like evaporative cooling units.
Innovation Solution
Pre-fabricated noise abatement walls with a frame, sound-insulating material, and screen material, designed to be assembled around mechanical equipment at the site, allowing for secure attachment to the equipment itself after setup, reducing on-site construction complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If noise abatement wall system is constructed as a stand-alone structure with separate foundation or buried support posts, then noise abatement function is achieved, but construction effort and complexity at the site increases significantly
Solution Approach 1:
The patent combines the noise abatement wall with the equipment housing into a single integrated structure. The wall panels are formed as integral extensions of the housing walls, eliminating the need for separate foundations or support posts. This merging of functions reduces construction complexity while maintaining noise abatement effectiveness.
Solution Approach 2:
The housing structure serves multiple functions: it protects the mechanical equipment and simultaneously acts as the noise abatement wall. The walls of the housing are designed to function both as structural enclosures and as noise barriers, eliminating the need for separate dedicated noise abatement structures.
2Stability of the object's composition
If noise abatement wall system is constructed as a stand-alone structure with separate foundation, then structural stability is achieved, but time and effort required for construction increases
Solution Approach 1:
The noise abatement wall structure is pre-integrated into the equipment housing design during manufacturing. The wall panels are formed as integral parts of the housing before the equipment is assembled and installed at the site, eliminating the need for time-consuming on-site construction of separate foundations and support structures.
Solution Approach 2:
By combining the housing structure and noise abatement wall into a single integrated unit, the patent eliminates the need for separate foundation construction. The housing itself provides the structural stability that would otherwise require separate foundational elements, significantly reducing construction time.
3Ease of operation
If noise abatement walls are pre-fabricated at factory and delivered to site for assembly, then ease of on-site assembly is improved, but transportation and logistics complexity increases
Solution Approach 1:
The patent combines the equipment and its housing (which includes the noise abatement walls) into a single factory-assembled unit. This integration means the noise abatement structure travels with the equipment as one package, eliminating the need for separate transportation and assembly logistics for the wall system.
Solution Approach 2:
The housing serves as both the equipment enclosure and the noise abatement structure, meaning only one component needs to be manufactured, transported, and installed. This multi-functionality simplifies logistics compared to transporting and assembling separate noise abatement walls.

AI summary
A noise abatement wall includes a frame defining a window, at least one shell, at least one sheet of sound-insulating material and a sheet of screen material. The at least one shell has a base panel portion and a peripheral panel portion integrally formed with and extending perpendicularly from the base panel portion to surround the base panel portion thereby forming a shell cavity. The at least one shell is sized and configured to be received by the window in a close-fitting relationship therewith and is connected to the frame. The at least one sheet of sound-insulating material is disposed in and occupies the shell cavity. The sheet of screen material covers the at least one sheet of sound-insulating material and is connected to the frame. A plurality of noise abatement walls are connected together to form a noise abatement wall system for abating noise generated from stationary noise-generating equipment.
