A system comprising a moisture-permeable channel integrated within the building structure, connected to a ventilation arrangement that supplies a controlled flow of gaseous medium to remove moisture through the channel, optimizing drying and curing processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional drying process using fans and heating elements is used, then moisture can be removed from building structures, but the drying and curing process takes long time

Engineering Contradiction:

Improvedrying speedVSAvoiddrying time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The building structure is segmented by integrating internal channels within the concrete or clay material itself. These channels divide the moisture removal pathway into multiple distributed flow paths, allowing simultaneous evaporation and transport of moisture from throughout the structure, dramatically accelerating the drying process compared to traditional surface-only methods.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A gaseous medium is introduced as an intermediary substance that flows through the internal channels of the building structure. This medium acts as a carrier to transport moisture vapor from the interior of the structure to the exterior, enabling efficient moisture removal without requiring prolonged exposure to heat or direct air circulation over the surface.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of time

If prefabricated dried concrete ground plate is used, then drying and curing time is reduced, but it is difficult to arrange for some kinds of building structures

Engineering Contradiction:

Improvedrying timeVSAvoidstructural adaptability

Core Design Contradiction:

Loss of timeVSAdaptability or versatility

Solution Approach 1:

The system provides a universal solution by integrating moisture removal channels directly into the building structure during construction. This multi-functional approach serves both structural formation and moisture control needs, making the system adaptable to various building structure types (walls, floors, different geometries) rather than requiring pre-dried standardized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The channels are installed in the building structure during the construction phase, before the structure is fully dried. This preliminary integration allows the moisture removal system to be built-in and operational from the start, eliminating the need for separate prefabricated dried components and enabling immediate moisture control as the structure cures.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If traditional heating elements are used for drying, then moisture can be removed, but the process is not environmentally friendly

Engineering Contradiction:

Improvedrying efficiencyVSAvoidenvironmental impact

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system replaces thermal-based drying (heating elements) with a mechanical flow-based approach. A gaseous medium is circulated through internal channels to physically transport moisture vapor out of the structure, eliminating or reducing the need for high-energy heating while maintaining effective moisture removal and reducing environmental impact.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
