Subfloor Segmentation for Water Damage Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building designs fail to effectively minimize water damage and mold growth, particularly in hidden areas, leading to significant renovation costs and health issues due to the spread of water and moisture through insulation layers and inadequate sealing.
Innovation Solution
A water damage minimization system featuring a separating barrier installed in the subfloor to divide rooms into watertight sections, combined with integrated moisture sensors for monitoring and early detection of water ingress, limiting damage to the area of origin and reducing renovation costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a coherent floor structure extending over all rooms is built, then the floor provides structural continuity and stability, but water penetrating at one point can spread throughout the entire floor, causing extensive damage and requiring complete renovation
Solution Approach 1:
The patent divides the floor structure into separate sections using waterproof partition walls that extend through the insulation layer and vapor barrier down to the concrete floor slab. These partition walls create watertight compartments in the underbody, preventing water from spreading across the entire floor while maintaining structural integrity through the segmented design.
2Loss of energy
If insulation layers and vapor barriers are used to provide thermal insulation, then energy efficiency is improved, but water can propagate horizontally through the insulation by capillary forces, creating hidden mold growth
Solution Approach 1:
The waterproof partition walls cut through the insulation layer and vapor barrier, dividing the underbody into separate compartments. This segmentation prevents capillary water propagation across the entire insulation layer while preserving the thermal insulation properties within each compartment.
Solution Approach 2:
The partition walls act as intermediary structures that block water movement through the insulation layer. By positioning these waterproof barriers within the insulation system, the patent prevents water from using the insulation as a pathway while maintaining the insulation's thermal performance.
3Device complexity
If the vapor barrier is omitted on upper floors to reduce construction complexity, then construction cost and complexity are reduced, but moisture can migrate from one room through mortar joints into adjacent rooms
Solution Approach 1:
Instead of relying on a continuous vapor barrier, the patent uses segmented waterproof partition walls at strategic locations such as room boundaries and penetration points. This approach provides moisture protection without requiring a complete vapor barrier system, reducing construction complexity while preventing moisture migration.
4Adaptability or versatility
If basement building technology is installed to provide essential functions, then building usability is improved, but water damage in the basement requires dismantling of this technology, limiting building usability and increasing renovation costs
Solution Approach 1:
The waterproof partition walls create separate watertight compartments in the basement underbody, isolating potential water damage to specific areas. This allows building technology in unaffected areas to remain operational during repairs, maintaining building usability while reducing renovation scope and costs.
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 system effectively contains water damage to specific areas, facilitating easier assessment and lower renovation costs by isolating affected sections and providing early warning through automated moisture monitoring, thus reducing the risk of widespread mold growth and infrastructure disruption.
Implementation Method 1
the water spreads from the collection point on the ground below the point of entry again by capillary forces or as water vapor horizontally in the ground
