Valley Roof Bracket with Pivoting Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Roofers face safety challenges when working at roof valleys due to the lack of a stable and level surface, as conventional roof jacks are not suitable for perpendicular angles, increasing the risk of falls and making the work more hazardous.
Innovation Solution
A valley roof jack with an upper and lower horizontal surface, supported by a pivoting and locking fastener system, an inward and outward support, and a hanging ring, which can be adjusted to fit different roof pitches and angles, providing a stable platform and allowing for secure attachment to the roof surface using a nailing surface with keyed holes, and optional standing seam roof connector for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional roof jacks are used on inclined roofs, then a stable platform is provided, but they cannot be used in valleys where sections of sloped roof come together at a perpendicular angle
Solution Approach 1:
The valley roof jack incorporates a horizontal support that can pivot relative to the upper and lower horizontal surfaces through a pivoting fastener system. This dynamic adjustment capability allows the jack to adapt to different roof pitch angles and valley configurations, enabling use in perpendicular angle valleys while maintaining stability. The pivoting mechanism transforms the static conventional jack into a dynamic structure that can accommodate varying geometric conditions.
2Reliability
If a stable platform is provided at roof valleys, then safety is improved, but the device complexity increases with additional fasteners and support structures
Solution Approach 1:
The valley roof jack is divided into distinct functional segments: upper horizontal surface, lower horizontal surface, horizontal support, inward support, outward support, and hanging ring. Each segment performs a specific function and can be independently adjusted or positioned. The pivoting fastener system separates the adjustment function from the locking function, allowing complex adaptive behavior through coordinated simple components rather than a monolithic complex structure.
Solution Approach 2:
The pivoting fastener system enables dynamic adjustment of the horizontal support angle to match different roof pitches, while the locking fastener provides static stability once positioned. This dynamic-to-static transition mechanism achieves high reliability across varying conditions without requiring a completely different jack design for each roof type.
3Adaptability or versatility
If the horizontal support is made adjustable for different roof pitches, then versatility is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The pivoting fastener system provides continuous angular adjustment capability through a controlled pivot range, while the locking fastener system provides discrete position locking. This combination allows the horizontal support to adapt to different roof pitches through geometric relationships and pivot angles rather than requiring precision-machined adjustment mechanisms, reducing manufacturing precision requirements while maintaining versatility.
