Roofing Ladder Bracket with Integrated Safety Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Asphalt roof shingles are frequently damaged during installation of roofing equipment, leading to costly and temporary repairs that fail due to sunlight and temperature exposure, and workers face safety hazards when accessing roof ridges without proper fall protection.
Innovation Solution
A bracket with a ladder clamping mechanism and safety attachment for securing ladders and safety equipment, made from rigid materials like sheet metal or polymers, which can be easily installed on various roof types and includes a conversion bracket for metal roofs, addressing both repair and safety issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional roofing cement or sealant is used to repair holes, tears, or punctures in asphalt shingles, then the repair can be applied quickly, but the repair fails within 7 years due to sunlight and temperature exposure
Solution Approach 1:
The patent employs disposable shingle patches that are designed for single-use installation over damaged areas. These patches are pre-formed with adhesive backing that provides immediate repair functionality without requiring long-term durability of the underlying shingle structure, thus resolving the contradiction between quick application and long-term reliability
Solution Approach 2:
The shingle patches are constructed using composite materials that combine asphalt saturation, fiberglass reinforcement, and weather-resistant adhesives. This composite structure provides both immediate bond strength for quick installation and long-term resistance to UV exposure and thermal cycling, thereby achieving both rapid repair and 7-year+ durability
2Strength
If ladder support brackets are installed using conventional methods with drilled holes and anchors, then the brackets can be securely mounted to the roof, but the installation process damages the asphalt shingles requiring costly repairs
Solution Approach 1:
The bracket mounting system utilizes a flexible membrane or thin film layer that can be adhered to the roof surface without penetrating the shingles. This flexible interface distributes mounting forces across a larger area, providing secure bracket attachment while preventing puncture holes and tears in the asphalt shingle layers
Solution Approach 2:
An intermediary mounting layer or adhesive system is introduced between the bracket and the shingle surface. This intermediary component provides the necessary mechanical strength for secure bracket installation while acting as a protective barrier that prevents direct contact between fasteners and the shingles, thereby eliminating shingle damage
3Ease of operation
If workers install safety equipment and ladder brackets without proper fall protection, then the installation process is simpler and faster, but workers face safety hazards when accessing roof ridges
Solution Approach 1:
The bracket system incorporates pre-integrated attachment points or integrated rail systems that are prepared in advance during bracket installation. These pre-positioned features enable workers to quickly connect fall protection equipment without requiring complex setup procedures, thus maintaining installation simplicity while eliminating fall hazards
