Solution Overview

Problem

Existing roof edge blocking systems lack efficient and economical solutions for enhancing perimeter resistance, ease of assembly and disassembly, durability, and cost-effectiveness while maintaining structural integrity.

Innovation Solution

A roof edge blocking system comprising a blocking assembly with a top flange, lateral flanges, an anchoring flange, and a locking tab, combined with a cover assembly featuring an angular wall and channel, allowing for secure mounting and easy assembly/disassembly without specialized tools, using fastening means like nails, screws, or adhesives.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional roof edge blocking systems are used, then structural integrity is maintained, but assembly complexity and cost increase

Engineering Contradiction:

Improveease of assemblyVSAvoidassembly complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The blocking assembly is divided into distinct components including lateral flanges, top flange, anchoring flange, and locking tabs, allowing for modular assembly and disassembly without specialized tools while maintaining structural integrity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The blocking assembly integrates multiple functions into a single unit combining lateral support, anchoring capability, and locking mechanisms, simplifying the overall system while reducing assembly complexity

Inventive Principle:

Principle #5Merging (Combining)

2Strength

If complex fastening systems are used, then perimeter resistance is enhanced, but cost and manufacturing complexity increase

Engineering Contradiction:

Improveperimeter resistanceVSAvoidmanufacturing cost

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

Instead of using complex fastening systems to achieve perimeter resistance, the invention uses simple overlapping flange geometry with inherent mechanical interlocking, where the shape itself provides the strength rather than additional fastening components

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The blocking assembly components are designed to self-align and self-lock through their geometric features, with locking tabs that automatically engage with corresponding channels, eliminating the need for complex fastening systems while maintaining perimeter resistance

Inventive Principle:

Principle #25Self-service

AI summary

A roof edge blocking with cleat having a blocking assembly with a top flange, a first lateral flange, a second lateral flange, an anchoring flange, and a locking tab; and a cover assembly having a cover top flange, an angular wall, a side flange, and a channel, whereby the cover assembly mounts onto the blocking assembly. The first lateral flange perpendicularly extends from the top flange. An upper wall and a lower wall of the anchoring flange extend perpendicularly from the first and second lateral flanges respectively, and are substantially parallel to the top flange. The upper wall and the lower wall are joined at the anchoring flange to define an elongated aperture. The locking tab extends outwardly from the second lateral flange defining a first predetermined angle. The first lateral flange has a first predetermined height and the second lateral flange has a second predetermined height.
