Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Workers and roofing materials often slide on sloped roofs, posing a risk of falling, and high friction boots do not always provide adequate protection against sliding.
Innovation Solution
A roofing construction tool with a compressible material stand and a high friction layer, featuring a tapering design and embedded weights, which enhances grip on the roof surface even in windy conditions, and includes multiple foam layers with varying densities for improved stability and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If workers wear high friction boots, then slippage of workers on sloped roofs is reduced, but workers can still slide and fall from the roof
Solution Approach 1:
The patent applies counterweight by embedding weights within the roofing construction tool to create a downward force that counteracts the upward sliding tendency of objects on sloped roofs. The weight-bearing tool is designed to press against the roof surface, generating a counteracting force that prevents both workers and materials from sliding downhill, thereby addressing the insufficient slip resistance of conventional high friction boots alone.
Solution Approach 2:
The patent introduces an intermediary device (the roofing construction tool with high friction layer and weights) that mediates between the worker/material and the sloped roof surface. This intermediary tool provides enhanced friction and counterweight functionality, transferring and distributing forces to prevent sliding without requiring direct worker intervention or modification of the roof surface.
2Productivity
If roofing materials and tools are placed on sloped roofs, then construction work can proceed, but materials and tools slide along the roof
Solution Approach 1:
The roofing construction tool incorporates embedded weights that generate a downward pressing force against the roof surface, creating a counterweight effect that prevents construction materials and tools from sliding. This allows materials to be securely positioned on sloped roofs during construction work, maintaining stability while enabling productivity.
Solution Approach 2:
The patent changes the physical parameters of the construction tool by incorporating weights and high friction materials, transforming it from a passive object into an active stabilization device. The weight-bearing tool modifies the force balance and friction characteristics at the contact interface with the roof, enabling materials to remain stationary on slopes where they would otherwise slide.
3Reliability
If a weight-bearing compressible tool is used, then grip on roof surface is enhanced, but device complexity increases
Solution Approach 1:
The patent employs composite materials by combining compressible foam layers with embedded weights and high friction surface layers. This composite structure integrates multiple functions (compression, weighting, friction enhancement) into a single tool, achieving reliable grip on roof surfaces while managing structural complexity through material composition rather than mechanical complexity.
Solution Approach 2:
The patent uses a compressible foam structure that acts as a flexible shell conforming to the roof surface. This flexible compressible material distributes the weight-bearing force across a larger contact area, enhancing grip stability while keeping the overall tool design relatively simple and adaptable to various roof geometries.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool effectively prevents sliding on roofs with inclines up to 60 degrees, providing enhanced safety and stability for workers and materials by maintaining a stationary position, even under high winds.
Implementation Method 1
a substantially planar stand comprising a compressible material that includes a top surface having a first area, a bottom surface defining a second area larger than the first area
Implementation Method 2
Gripping of the bottom surface of the roofing construction tool to a roof surface can be enhanced by providing a high friction layer adjacent the bottom surface

AI summary
A roofing construction tool including a substantially planar stand formed from a compressible material that includes a top surface, a bottom surface, and side walls joining the top surface and bottom surface. The roofing construction tool may include friction enhancing structure provided on or adjacent the bottom surface and/or at least one weight embedded in the compressible material and having a density greater than a density of the compressible material.
