Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional rainscreen drainage systems are used, then moisture drainage is provided, but the systems fail to adequately drain and ventilate moisture leading to rot and material damage

Engineering Contradiction:

Improvemoisture drainage effectivenessVSAvoidrot and material damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The termination assembly is divided into distinct functional components: a termination member with connecting and supporting flanges, a drainage member with outwardly and inwardly extending portions, and a filter member. This segmentation allows each component to perform its specific function optimally, ensuring reliable moisture drainage while preventing rot and material damage through the combined action of drainage, filtration, and ventilation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The drainage member acts as an intermediary element between the termination member and the filter member, creating voids that facilitate moisture movement while the filter member intercepts debris. This intermediary structure ensures that moisture is effectively drained and ventilated without causing rot or material damage to the building materials.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If rainscreen drainage systems are installed to provide air gap and ventilation, then moisture drainage is improved, but termination functionality is often inadequate

Engineering Contradiction:

Improveventilation effectivenessVSAvoidtermination assembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention merges the termination function with the drainage and ventilation functions into a single integrated assembly. The termination member, drainage member, and filter member are combined into one assembly that simultaneously provides structural termination, moisture drainage, ventilation, and debris filtration, thereby improving ventilation effectiveness without proportionally increasing device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The termination assembly is designed as a multi-functional component that performs multiple functions: structural termination via the termination member, moisture drainage through the drainage member's voids, ventilation through the created air gaps, and debris filtration via the filter member. This universality allows a single assembly to address multiple requirements simultaneously, improving ventilation effectiveness while managing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If drainage members create voids for drainage and ventilation, then moisture drainage is facilitated, but device complexity increases

Engineering Contradiction:

Improvemoisture drainage efficiencyVSAvoiddrainage assembly structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The drainage member employs a thin-walled structure with outwardly and inwardly extending portions that create voids for drainage and ventilation. This thin-film approach allows the creation of complex three-dimensional void structures without proportionally increasing material usage or overall device complexity, thereby improving moisture drainage efficiency while maintaining reasonable structural simplicity.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A termination assembly comprises a termination member and a drainage assembly. The termination member includes a base interconnecting a connecting flange and a supporting flange, and the base is configured and arranged to receive a portion of a wall between the connecting flange and the supporting flange. The drainage assembly includes a drainage member operatively connected to the base, and the drainage member creates a void to facilitate drainage and ventilation.
