Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional drainage planes are formed using lapping tar paper, crinkled building wraps, or sheeting materials, then drainage functionality is achieved, but additional construction steps, labor, and materials are required

Engineering Contradiction:

Improvedrainage functionalityVSAvoidconstruction process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the drainage plane functionality directly into the sheathing panel by forming raised elements on the panel surface itself. This integration eliminates the need for separate drainage materials and installation steps, as the sheathing panel simultaneously serves as both structural support and drainage surface.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sheathing panel is designed to perform multiple functions: providing structural support, creating drainage pathways through raised elements, and eliminating the need for separate drainage materials. This multi-functionality reduces overall construction complexity while maintaining drainage reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If building envelop sheet materials with drainage properties or entangled mesh materials are used, then drainage plane is formed, but additional installation steps and materials are required

Engineering Contradiction:

Improvedrainage plane formationVSAvoidconstruction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The drainage plane is merged with the sheathing panel manufacturing process itself. Raised elements are formed on the panel surface during or after panel production, allowing the drainage functionality to be built-in rather than added during construction, thereby improving productivity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The drainage elements are prepared and formed on the sheathing panel during the panel manufacturing process or immediately afterward, before installation on the building. This preliminary preparation eliminates the need for separate drainage material installation steps during construction, improving overall construction efficiency.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If lathing, channeling, or mechanical spacers are attached to the assembly, then drainage plane is created, but additional construction steps and materials are required

Engineering Contradiction:

Improvedrainage plane creationVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The drainage plane is merged into the sheathing panel structure itself through raised elements formed on the panel surface. This eliminates the need for separate lathing, channeling, or mechanical spacer components, thereby reducing assembly complexity while maintaining drainage reliability.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If separate drainage materials and installation steps are used, then drainage functionality is achieved, but construction time and labor increase

Engineering Contradiction:

Improvewater redirection capabilityVSAvoidconstruction time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The drainage functionality is merged into the sheathing panel itself, eliminating the need for separate drainage material installation. This integration directly reduces construction time while maintaining the capability to redirect water through the raised elements formed on the panel surface.

Inventive Principle:

Principle #5Merging (Combining)
