Solution Overview

Problem

Existing methods for attaching utility pipes and components to parapet walls on rooftops involve the use of fasteners that penetrate the wall, causing damage, voiding warranties, and creating potential leak points.

Innovation Solution

A parapet bracket system that attaches to the parapet wall without penetrating it, using a U-shaped design with adjustable spacing to accommodate different wall thicknesses, allowing pipes to be secured indirectly through the bracket.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If fasteners are used to attach pipes directly to the parapet wall, then the attachment strength is improved, but the parapet wall is damaged and warranty is voided

Engineering Contradiction:

Improveattachment strengthVSAvoidwall damage

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a parapet bracket as an intermediary component between the pipe and the parapet wall. The bracket attaches to the wall using non-penetrating methods (adhesives, mechanical anchors in the masonry without penetrating the weather barrier) while providing strong attachment points for pipes through threaded holes in the bracket itself. This mediator resolves the contradiction by distributing attachment forces without compromising the wall's weather barrier integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The attachment system is segmented into distinct functional components: the parapet bracket (with body, mounting surface, and pipe attachment features) separate from the wall and pipe. This segmentation allows each component to be optimized independently - the bracket provides strong pipe attachment while the wall remains intact, resolving the contradiction between attachment strength and wall preservation.

Inventive Principle:

Principle #1Segmentation

2Reliability

If fasteners penetrate the parapet wall to secure pipes, then the pipe attachment reliability is improved, but leak points are created

Engineering Contradiction:

Improvepipe attachment reliabilityVSAvoidleak points

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The parapet bracket serves as a mediator that eliminates the need for penetrating fasteners through the wall. The bracket's mounting surface attaches to the wall using non-penetrating methods, and the pipe attaches to the bracket through threaded holes in the bracket material itself. This creates a reliable pipe attachment while maintaining the wall's weather barrier continuity, thus eliminating leak points.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of attaching the pipe directly to the wall (which requires penetrating fasteners), the invention inverts the attachment sequence: first attach the bracket to the wall non-penetratingly, then attach the pipe to the bracket. This inversion resolves the contradiction by separating the wall attachment function from the pipe attachment function.

Inventive Principle:

Principle #13The other way round (Inversion)

3Object-affected harmful factors

If a non-penetrating attachment method is used to protect the parapet wall, then wall integrity is maintained, but the attachment strength may be reduced

Engineering Contradiction:

Improvewall integrityVSAvoidattachment strength

Core Design Contradiction:

Object-affected harmful factorsVSStrength

Solution Approach 1:

The parapet bracket as an intermediary component compensates for the reduced strength of non-penetrating wall attachment methods. The bracket itself provides strong pipe attachment points through threaded holes and mounting surfaces, while its attachment to the wall uses multiple non-penetrating methods (adhesives, mechanical anchors) that collectively provide sufficient holding strength without compromising wall integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The bracket assembly functions as a composite system combining different attachment mechanisms: adhesives for bonding, mechanical anchors for physical securing, and threaded fasteners for pipe attachment. This composite approach achieves both wall integrity and sufficient attachment strength simultaneously.

Inventive Principle:

Principle #40Composite materials

AI summary

A parapet bracket is disclosed that may be mounted on a parapet wall of a roof without the usage of fasteners. The parapet bracket may be used to attach utility pipes to the parapet wall without using fasteners directly on the parapet wall. The parapet bracket may have a short leg, long leg, and a connecting plate between the two legs that form an inverted U-shape. The short leg may be used to hook the parapet bracket on the parapet wall, and the long leg may be used to couple pipes to the parapet bracket. Consequently, the pipes may be mounted to the parapet wall indirectly and without having to pierce the parapet wall with fasteners, such as screws and nails.
