Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall, ceiling, and floor construction components lack specific physical properties such as thermal energy storage, enhanced sound transmission reduction, and increased burn resistance, which are necessary for certain applications, and existing solutions fail to effectively enhance these properties without compromising other essential characteristics.
Innovation Solution
An underlayment system that supplements the physical properties of conventional construction components by incorporating phase change materials, sound-deadening materials, and burn-resistant layers, which can be integrated between or beneath standard construction components to form enhanced assemblies that maintain or exceed the desired performance criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wall, ceiling, and floor construction components are used, then basic construction requirements are met, but physical properties such as thermal energy storage, sound transmission reduction, and burn resistance are insufficient
Solution Approach 1:
The patent applies composite materials by combining conventional construction components (gypsum boards, cement boards, wood fiber boards) with specialized functional layers including phase change materials for thermal energy storage, sound-deadening materials for acoustic insulation, and burn-resistant materials for fire protection. This creates a multi-layer composite structure that integrates multiple functions within a single construction assembly, simultaneously achieving basic construction requirements and enhanced physical properties.
Solution Approach 2:
The patent implements the nesting principle by placing functional underlayment layers between or beneath standard construction components. The phase change materials, sound-deadening materials, and burn-resistant layers are nested within the construction assembly structure, allowing each layer to contribute its specific function while maintaining the overall integrity of the construction component.
2Reliability
If existing wall, ceiling, and/or floor construction components are removed to enhance performance, then physical properties can be improved, but construction complexity and cost increase
Solution Approach 1:
The patent applies preliminary action by pre-fabricating the underlayment layers with functional materials before installation. The phase change materials, sound-deadening materials, and burn-resistant layers are prepared and integrated into underlayment assemblies in advance, allowing for streamlined on-site installation without requiring removal of existing construction components. This pre-preparation reduces construction complexity while maintaining performance enhancement capabilities.
3Reliability
If functional layers are added to conventional construction components, then physical properties are enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the enhanced construction assembly into distinct modular layers: conventional construction components (gypsum boards, cement boards, wood fiber boards) and functional underlayment layers (phase change materials, sound-deadening materials, burn-resistant materials). Each layer can be manufactured and prepared separately, then assembled together, simplifying the manufacturing process while maintaining the benefits of enhanced physical properties.

AI summary
An underlayment for supplementing one or more physical properties of wall, ceiling, and floor construction components is used to in a wall, ceiling, or floor assembly that may be fabricated on site. The assembly includes: first and second wall, ceiling, or floor construction components which each have physical properties and an underlayment component which has at least one supplemental physical property for supplementing the physical properties of the first and second construction components. The construction components may or may not be secured together with the underlayment sandwiched between the second and first construction components to form a wall, ceiling, or floor assembly with the supplemental physical property or properties of the underlayment. The supplemental physical property or properties of the underlayment may include, but are not limited to, latent storage of thermal energy, sound transmission reduction, and/or burn through resistance.
