Solution Overview

Problem

Existing construction methods require additional steps, labor, and materials to create a drainage plane in walls, which is inefficient and time-consuming.

Innovation Solution

Construction panels with integrated drainage mechanisms featuring angled, elongated, linear raised elements on their surface that facilitate unidirectional water funneling, eliminating the need for separate installation steps and materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional drainage plane methods (lapping tar paper, crinkled building wraps, entangled mesh materials, lathing, or mechanical spacers) are used, then a drainage plane can be formed to control and redirect water flow, but additional construction steps, labor, and materials are required

Engineering Contradiction:
Improvedrainage plane effectivenessVSAvoidconstruction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The drainage plane functionality is merged directly into the sheathing panel by integrating raised elements during panel manufacturing. This eliminates the need for separate drainage plane materials and installation steps, as the sheathing panel itself provides both structural support and water drainage capabilities through its integrated raised elements that create channels for water flow

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The drainage mechanism is prepared in advance during sheathing panel manufacturing rather than being installed during construction. The raised elements are pre-formed on the sheathing panel surface, so when the panel is installed, the drainage plane is automatically created without requiring additional on-site assembly or installation steps

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple separate components (sheathing, drainage plane materials, insulation, cladding) are used to create a complete wall assembly with drainage, then each component can perform its specific function, but the device complexity and number of installation steps increase

Engineering Contradiction:
Improvefunctional capabilityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sheathing panel is designed to perform multiple functions simultaneously: it provides structural support, serves as a drainage plane through its raised elements, acts as an attachment surface for insulation and cladding, and facilitates water drainage. This multi-functional design eliminates the need for separate dedicated drainage plane materials and reduces the overall complexity of the wall assembly

Inventive Principle:
Principle #6Universality (Multi-functionality)
