Adjustable Roof Jack Assembly for Variable Roof Pitches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof jack systems require a large inventory and high storage costs due to the need for multiple variations to accommodate different roof pitches, leading to costly delays and uncovered openings when the wrong pitch is installed.
Innovation Solution
An adjustable roof jack design featuring a flange, tapered cylinders with foldable sections, and a vent cap assembly that can be rotated to accommodate roof pitches from 0-45 degrees, allowing for a single product to fit various slopes without the need for multiple stock keeping units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple variations of roof jacks are constructed and manufactured for different roof slopes, then the adaptability to different roof pitches is improved, but the device complexity and inventory requirements increase
Solution Approach 1:
The roof jack incorporates a dynamically adjustable mechanism that allows the flange to be positioned at different angles relative to the cylinder body. This dynamic adjustment capability enables a single roof jack design to accommodate various roof pitches from 0 to 45 degrees, eliminating the need for multiple fixed-angle variations and reducing inventory complexity while maintaining full adaptability.
2Adaptability or versatility
If multiple stock keeping units are maintained to accommodate full range of slopes, then the adaptability to different roof pitches is improved, but the loss of energy and storage costs increase
Solution Approach 1:
The roof jack is designed as a universal product that can perform multiple functions across different roof pitch applications. By integrating an adjustable flange mechanism, a single universal roof jack model can replace multiple specialized models, thereby reducing storage space requirements, lowering inventory carrying costs, and eliminating the need to maintain extensive SKU variations while still providing complete coverage for all roof slopes from 0 to 45 degrees.
3Ease of operation
If the wrong pitch roof jack is installed, then the ease of operation is improved during ordering, but the loss of time and project delays increase
Solution Approach 1:
The adjustable flange mechanism is segmented into discrete angular positions that correspond to different roof pitch requirements. This segmentation allows installers to easily select and adjust the appropriate angle during installation, providing clear guidance and reducing the risk of incorrect installation. Combined with the universal design, this ensures that any roof jack from this product line can be correctly adapted to the specific roof pitch, eliminating delays caused by ordering errors.
