Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soundproofing solutions, such as wood fiber panels and metal plates with insulating materials, are costly and have short lifespans, and existing concrete construction elements lack effective soundproofing capabilities, requiring multiple materials for both retaining and soundproofing functions, increasing construction time and cost.
Innovation Solution
A concrete construction element with projections on its outer surface and internal walls of varying sizes to disperse and absorb acoustic waves, allowing for a single material solution that reduces construction time and cost, and can be assembled dry without binders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wood fiber panels or metal plates with insulating materials are used for soundproofing, then sound absorption effectiveness is improved, but cost price and lifespan are worsened
Solution Approach 1:
The patent uses concrete as a composite material that inherently provides both structural strength and sound absorption capabilities. The concrete structure incorporates internal cavities and projections that work together to absorb and dissipate sound waves, eliminating the need for separate soundproofing materials like wood fiber panels or metal plates with insulating materials.
Solution Approach 2:
The concrete construction element serves multiple functions simultaneously: it provides structural support for the retaining wall, acts as a soundproofing barrier, and incorporates acoustic wave absorption through its geometric features. This multi-functionality eliminates the need for separate soundproofing materials and extends the lifespan by using a single durable material system.
2Reliability
If multiple materials are used for both retaining wall and soundproofing functions, then soundproofing effectiveness is improved, but device complexity and construction time are worsened
Solution Approach 1:
The patent merges the retaining wall structure and soundproofing function into a single integrated concrete construction element. The element incorporates internal cavities, projections on external surfaces, and geometric configurations that provide both structural support and acoustic wave absorption, eliminating the need for separate soundproofing materials and simplifying the overall system.
Solution Approach 2:
The concrete construction element serves multiple functions simultaneously: it provides structural support for the retaining wall, acts as a soundproofing barrier, and incorporates acoustic wave absorption through its geometric features. This multi-functionality eliminates the need for separate soundproofing materials and extends the lifespan by using a single durable material system.
3Reliability
If multiple materials are used for retaining wall and soundproofing, then soundproofing effectiveness is improved, but construction time is worsened
Solution Approach 1:

The element incorporates internal cavities, projections on external surfaces, and geometric configurations that provide both structural support and acoustic wave absorption, eliminating the need for separate soundproofing materials and simplifying the overall system.
Solution Approach 2:
The construction element is pre-formed with integrated soundproofing features during manufacturing, including internal cavities and external projections. This preliminary integration of acoustic wave absorption structures eliminates the need for on-site installation of separate soundproofing materials, thereby reducing construction time while maintaining effectiveness.
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
The solution significantly enhances acoustic performance by directing sound waves into cavities filled with absorbent materials, providing effective soundproofing while using a single material type and reducing construction complexity and time.
Implementation Method 1
the projections have the result of directing the sound waves towards the cavities formed by the assembly of the construction elements
Implementation Method 2
The cavities are preferably filled with filling materials having good sound wave absorption efficiency. Friable materials such as earth or sand can be used.
