Solution Overview
Problem
Existing methods for forming building foundations face challenges in drying and curing due to the presence of insulating materials like cellular plastic, which impedes upward drying, and are ineffective against external moisture, leading to prolonged construction times and potential damage.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a thick layer of cellular plastic insulating material is used below the concrete ground plate, then insulating properties are improved, but drying and curing time increases significantly
Solution Approach 1:
The patent applies pneumatic principles by introducing a channel system that delivers pressurized or vacuum air flow directly into the concrete ground plate and insulating material. This forced air circulation accelerates moisture removal from the concrete structure, enabling faster drying and curing times even when thick insulating layers are present below the foundation.
Solution Approach 2:
The patent utilizes the porous structure of concrete and insulating materials by incorporating channels and cavities that allow air penetration deep into the material matrix. This porous approach enables moisture to be extracted from within the concrete and insulation layers, resolving the contradiction between maintaining thick insulation and achieving rapid drying.
2Loss of time
If a prefabricated concrete ground plate is used, then drying and curing time on site is reduced, but the ability to provide a leveled foundation and resist external moisture is compromised
Solution Approach 1:
The patent segments the foundation system into modular components: a concrete ground plate, an insulating material layer with integrated channels, and a sensor network. This segmentation allows the use of prefabricated elements for rapid installation while incorporating adjustable channel systems that can be configured to provide proper leveling and moisture protection, combining the speed of prefabrication with the reliability of customized foundation preparation.
Solution Approach 2:
The channel system serves multiple functions simultaneously: it provides structural support for leveling the foundation, acts as a moisture extraction pathway, enables sensor integration for monitoring, and facilitates air circulation for drying. This multi-functionality allows a single integrated system to address all foundation requirements that were previously handled by separate components.
3Temperature
If traditional insulating material is used below the concrete ground plate, then insulating properties are achieved, but moisture removal capability is severely limited
Solution Approach 1:
The patent employs pneumatic technology by installing channels within the insulating material that deliver pressurized or vacuum air flow directly to moisture sources in the concrete and insulation. This forced air movement dramatically enhances moisture removal efficiency compared to passive drying, while the channels are strategically positioned to maintain the insulating material's thermal performance.
Solution Approach 2:
The channel system acts as an intermediary between the insulating material and the external environment, providing a dedicated pathway for moisture extraction without compromising the insulation's thermal barrier function. The channels enable moisture removal through the insulation layer while the insulation continues to perform its primary heat transfer resistance function.
