Solution Overview

Problem

Traditional cladding systems for buildings often trap moisture, leading to degradation of building paper, underlying sheathing, and wood framing due to restricted ventilation and drainage, which obstructs water flow and causes saturation.

Innovation Solution

A vented and water control weatherproofing cladding system featuring exterior cladding panels with an omnidirectional relief pattern on their back surfaces, creating a ventilation and drainage plane that allows air and moisture to flow freely in any direction, eliminating the need for additional structures like furring strips.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional lapped siding installation is used, then water shedding function is improved, but moisture trapping and ventilation obstruction occur

Engineering Contradiction:
Improvewater sheddingVSAvoidmoisture trapping
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent introduces a third dimension by creating a raised relief pattern on the back surface of siding panels, transforming the traditional flat two-dimensional contact surface into a three-dimensional structure with channels and cavities. This dimensional change enables simultaneous water shedding and ventilation functions by creating pathways for moisture to escape while maintaining the overlapping installation method.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The back surface of the siding panel is segmented into multiple functional zones: raised relief patterns forming ventilation channels, recessed areas creating drainage pathways, and specific contact zones for water shedding. This segmentation allows different regions to perform different functions (ventilation, drainage, water shedding) simultaneously, resolving the contradiction between water shedding and moisture trapping.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If siding back surface contacts building paper tightly, then installation simplicity is improved, but drainage and ventilation are obstructed

Engineering Contradiction:
Improveinstallation simplicityVSAvoiddrainage and ventilation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The siding back surface features local quality variations with raised relief patterns in specific locations creating ventilation channels and drainage pathways, while other areas maintain contact with the building paper for structural support and water shedding. This localized differentiation allows the siding to simultaneously achieve installation simplicity through broad contact while maintaining reliability through localized ventilation and drainage channels.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If smooth back surface siding is used, then manufacturing simplicity is improved, but ventilation and drainage channels cannot be formed

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidventilation and drainage function
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent merges the ventilation channel formation and drainage pathway creation into a single integrated raised relief pattern that is formed during the siding manufacturing process. This consolidation allows the siding to gain multiple functions (ventilation, drainage, water shedding) without requiring separate manufacturing steps or additional components, thus maintaining manufacturing simplicity while achieving enhanced adaptability.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A vented and water control paneling has improved drainage and integrated ventilation air space. The water control paneling may be fabricated with an omnidirectional relief pattern formed on its back surface. The relief pattern spaces the vented and water control paneling away from a structure to which it is secured, thereby providing an omnidirectional drainage plane between the back surface of the paneling and the structure. The omnidirectional drainage plane provides an unimpeded ventilation and drainage path of water and/or water vapor.
