Noise Insulation Element With Perpendicular Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noise protection elements and walls fail to effectively absorb noise due to unsatisfactory absorption capabilities.
Innovation Solution
The noise protection element features channels on the surface facing the noise source that lead into the interior, where sound waves are absorbed by a sound-absorbing material, minimizing reflections and optimizing noise absorption by varying channel shape, size, and length to adapt to different noise frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional noise protection elements with solid walls are used, then structural strength is maintained, but noise absorption capability is insufficient
Solution Approach 1:
The patent applies porous materials by incorporating channels with through-holes in the noise protection element walls. These channels create a porous structure that allows sound waves to penetrate through the element, significantly improving noise absorption capability while maintaining structural integrity through the controlled distribution of channels within the wall framework
Solution Approach 2:
The patent segments the solid wall structure by introducing multiple channels with through-holes distributed throughout the noise protection element. This segmentation divides the continuous wall into multiple pathways for sound transmission, enhancing noise absorption while preserving the overall structural strength through the distributed channel arrangement
2Object-affected harmful factors
If channels with through-holes are introduced to improve noise absorption, then noise destruction capability increases, but device complexity increases
Solution Approach 1:
The complexity is managed by segmenting the noise protection element into standardized modules, each containing a specific pattern of channels with through-holes. This modular segmentation allows for systematic production and assembly, reducing overall device complexity while maintaining effective noise destruction capability through the distributed channel network
Solution Approach 2:
The channels with through-holes serve multiple functions simultaneously: they act as sound transmission pathways for noise absorption, provide structural reinforcement when properly distributed, and can be configured in standardized patterns for easy manufacturing. This multi-functionality reduces device complexity by eliminating the need for separate components for each function

Implementation Method 1
Sound waves are received in the channels and passed through the channels to the insulating material (layer of sound-absorbing material) located inside the noise protection elements according to the invention, where they are destroyed.
Data Source
AI summary
The element is included in a wall having openings and arranged inside to provide a sound absorbing position. The openings have channels (27) which are arranged near sound-absorbing location. In the channels, tubes (29) are formed. The tubes (29) are oriented perpendicular to the noise source of the wall of the noise element.
