Solution Overview

Problem

Current methods for installing pitch pockets on roofs using pourable sealant and unconventional fill materials lead to increased potential failure due to incompatibility and cracking, resulting in leakage issues and prolonged curing times.

Innovation Solution

An insert for a pitch pocket system comprising two lightweight fully dried concrete portions with openings, configured to form a larger opening to receive roof penetrations, which are receptive to pourable sealants, reducing the need for excess sealant and minimizing incompatibility issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If unconventional fill materials (granules, sand, rags, gravel, scrap pieces) are used to reduce pourable sealant usage, then the amount of sealant needed is reduced, but the reliability of the pitch pocket decreases due to incompatibility and cracking

Engineering Contradiction:
Improveamount of pourable sealantVSAvoidpitch pocket seal integrity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent introduces a specialized insert as an intermediary component between the pitch pocket and the pourable sealant. This insert is specifically designed to be compatible with the sealant chemistry, creating a reliable bonding interface that prevents cracking and leakage while reducing the overall sealant quantity needed.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The insert changes the physical and chemical parameters of the pitch pocket interior surface, providing a optimized substrate that enhances sealant adhesion. This parameter modification ensures compatible interaction between the sealant and the insert material, eliminating the cracking issues associated with unconventional fill materials.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If pourable sealant is used to seal the pitch pocket, then the pitch pocket can be sealed, but the curing time is prolonged and installation time is extended

Engineering Contradiction:
Improveseal formationVSAvoidcuring time and installation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The insert is pre-prepared and positioned within the pitch pocket before applying the pourable sealant. This preliminary action creates an optimized surface that accelerates the curing process and ensures proper seal formation, thereby reducing the overall installation and curing time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The insert acts as a catalyst or mediator that facilitates faster curing of the pourable sealant. By providing a chemically compatible surface, the insert accelerates the curing reaction, reducing the time required for the seal to reach full strength and functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If excess pourable sealant is used to ensure proper sealing, then the seal integrity is improved, but the material usage increases and waste is generated

Engineering Contradiction:
Improveseal integrityVSAvoidpourable sealant material
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The insert serves as a mediator that enables effective sealing with reduced sealant quantities. By providing a optimized bonding surface, the insert ensures proper seal integrity without requiring excess sealant, thereby minimizing material waste and loss.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The insert modifies the surface parameters of the pitch pocket to enhance sealant adhesion and distribution efficiency. This parameter change allows the sealant to bond more effectively with smaller quantities, reducing material usage while maintaining seal integrity.

Inventive Principle:
Principle #35Parameter changes
