Ladder Stabilizer Triangular Supports Roof Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ladder stabilizers fail to protect slate, tile, or other roofing materials and do not provide a slip-free surface, and can damage non-asphalt roofs due to insufficient surface area contact.
Innovation Solution
A ladder with a distally attached curved metal support and triangular supports covered with a high friction coefficient surface, such as rubber, which allows for increased surface area contact and stability on angled roofs, and is pivotable to accommodate different roof pitches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional ladder stabilizers are used, then the ladder can be stabilized on flat surfaces, but they damage non-asphalt roofs due to insufficient surface area contact
Solution Approach 1:
The stabilizer is divided into multiple triangular supports instead of a single contact point, distributing the contact area across multiple points to prevent concentration of force on one location, thereby protecting the roof from damage while maintaining stability
Solution Approach 2:
The triangular supports are covered with a high friction coefficient surface material (such as rubber) specifically at the contact areas, providing localized enhanced friction and surface area contact where needed to prevent sliding and protect the roof
2Stability of the object's composition
If traditional ladder stabilizers are used, then the ladder can be stabilized, but they do not provide a slip-free surface on various roofing materials
Solution Approach 1:
The triangular supports are covered with a high friction coefficient surface material (such as rubber) specifically at the contact areas, providing localized enhanced friction and surface area contact where needed to prevent sliding and protect the roof
Solution Approach 2:
The stabilizer combines metal triangular supports with high friction coefficient surface materials (such as rubber coatings), creating a composite structure that provides both structural integrity and enhanced friction for slip prevention
3Device complexity
If fixed triangular supports are used, then the ladder is simple in structure, but it cannot accommodate roofs of different pitches
Solution Approach 1:
The triangular supports are made pivotably affixed to the curved metal support, allowing them to rotate and adjust their angle relative to the ladder, enabling adaptation to roofs of different pitches while maintaining structural simplicity
Solution Approach 2:
The stabilizer is divided into multiple triangular supports instead of a single contact point, distributing the contact area across multiple points to prevent concentration of force on one location, thereby protecting the roof from damage while maintaining stability

Function Achieved in This Case
The solution provides enhanced stability and prevents slipping on various roofing materials, including non-asphalt roofs, by increasing the frictional contact area and accommodating different roof pitches, thus ensuring safe and damage-free use.

AI summary
A ladder with a distally attached curved metal support with two triangular supports which are covered with a high friction coefficient surface such as rubber. These triangular supports allow for greater surface area contact on angled roofs so that the supports won't damage non-asphalt roofs. The triangular supports also allow additional stability to prevent the ladder from sliding off the side of a roof.
