Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing subflooring systems lack effective moisture drainage and air circulation capabilities, particularly in basement environments where moisture and cold concrete pose challenges, leading to potential mold, rot, and temperature control issues.
Innovation Solution
A subfloor drainage panel with an upper member, a lower member featuring drainage holes and projections for fluid passage, and an intermediate member for insulation, allowing interlocking edges for panel connection and a ventilation manifold for air circulation, enabling efficient moisture drainage and air exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed subfloor system is used on concrete foundation, then structural stability is improved, but moisture drainage capability deteriorates
Solution Approach 1:
The subfloor system is divided into modular panels with integrated drainage channels and projections. Each panel segment contains internal drainage pathways that channel moisture to collection points, allowing the stable fixed subfloor structure to simultaneously provide effective moisture drainage through its segmented design.
Solution Approach 2:
Drainage projections and channels act as intermediary structures between the subfloor panels and the concrete foundation. These intermediaries capture and redirect moisture flow, preventing direct contact between moisture and the subfloor while maintaining the stability of the fixed subfloor system.
2Ease of manufacture
If traditional subflooring is used, then ease of installation is improved, but air circulation capability deteriorates
Solution Approach 1:
The subfloor panels are designed to perform multiple functions simultaneously: providing structural support, enabling moisture drainage through integrated channels, and facilitating air circulation through raised projections and gaps. This multi-functional design maintains ease of installation as a single modular unit while adding drainage and ventilation capabilities.
Solution Approach 2:
The drainage projections extend vertically from the subfloor panel, creating a three-dimensional structure that enables air circulation channels. This vertical dimension addition allows air to flow underneath and through the subfloor system without complicating the horizontal installation process.
3Strength
If solid subfloor panels are used, then structural strength is improved, but moisture permeability deteriorates
Solution Approach 1:
The subfloor panels feature localized drainage channels and projections at specific positions rather than being uniformly permeable throughout. This allows the majority of the panel to maintain solid, strong construction while specific local areas provide moisture drainage pathways, achieving both structural strength and moisture permeability where needed.

AI summary
A subfloor drainage panel is provided for draining moisture from a floor. The subfloor drainage panel has an upper member, a lower member attached to the upper member, and an intermediate member located in the lower member. The lower member includes a plurality of first projections extending away from the upper member, a plurality of second projections extending toward the upper member, and at least one drain hole defined in the first projections. The first projections support the subfloor drainage panel on a surface. The intermediate member has a plurality of openings each configured to receive therethrough a portion of one of the second projections so as to contact and support the lower member. The lower member is configured to define a gap between a portion of the lower member and the surface, with the gap being configured to allow fluid to pass therethrough.
