Solution Overview

Problem

Conventional building materials, such as drywall, have limited soundproofing capabilities due to gaps and cracks that allow sound transmission, and the incorporation of microparticles like cenospheres or synthetic microparticles is either costly or inconsistent in quality.

Innovation Solution

A composition comprising microparticles, sodium silicate binder, and isocyanate setting agent is used to create a core matrix for wallboard, which sets within one hour and cures under ambient or elevated temperatures, providing enhanced soundproofing and structural integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional drywall is used for soundproofing, then the structure is simple and cost-effective, but sound transmission is high due to gaps and cracks

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent uses a composite material comprising microparticles (such as cenospheres), sodium silicate binder, and isocyanate setting agent to form a core matrix that provides superior soundproofing. This composite material fills gaps and cracks more effectively than conventional drywall, reducing sound transmission through the wall assembly while maintaining structural integrity.

2Object-affected harmful factors

If microparticles like cenospheres or synthetic microparticles are incorporated into building materials, then soundproofing and thermal insulation are improved, but the cost increases significantly

Engineering Contradiction:

Solution Approach 1:

The patent optimizes the parameters of the microparticle composition, specifically using naturally occurring cenospheres (which are less expensive than synthetic microparticles) combined with sodium silicate binder and isocyanate setting agent. This parameter change reduces material cost while maintaining the soundproofing and thermal insulation benefits of microparticle incorporation.

Core Design Contradiction:

TemperatureVSStability of the object's composition

Solution Approach 1:

The patent creates a composite material system where microparticles are bound together with sodium silicate and isocyanate setting agent to form a consistent core matrix. This composite structure ensures uniform distribution of microparticles and consistent material properties, improving thermal insulation while maintaining material consistency throughout the wallboard product.

Inventive Principle:

Core Design Contradiction:

Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The patent changes the material composition parameters by incorporating lightweight microparticles (cenospheres) into the wallboard core matrix. This allows achievement of superior soundproofing performance without increasing thickness or weight, as the microparticle structure provides sound damping while maintaining low density.
