Integrated Sump Drain Ramp for Roof Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roofing drainage systems are prone to leaks due to differences in thermal expansion of components, leading to water intrusion and potential structural failures, and are costly and time-consuming to install.
Innovation Solution
A sump drain apparatus with a single, continuous structure comprising a drain inlet, ramp, and attachment portion, featuring insulation beneath the ramp and a roof membrane coupled to the second land, which directs drainage water efficiently and reduces the likelihood of leaks by minimizing the concentration of water at mating points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional multi-component drainage systems are used, then drainage function is achieved, but leak risk increases due to thermal expansion differences at mating points
Solution Approach 1:
The patent combines multiple separate components (drain inlet, ramp, attachment portion, and insulation) into a single integrated sump drain apparatus. This merging eliminates the mating points between separate components that were prone to leaking due to thermal expansion differences, while maintaining all necessary drainage functions.
2Productivity
If conventional drainage systems with multiple components are used, then drainage function is achieved, but installation time and cost increase
Solution Approach 1:
The integration of multiple components into a single apparatus reduces the number of installation steps, eliminates the need for precise alignment and sealing between multiple parts, and simplifies the overall installation process, thereby reducing both time and labor costs.
3Reliability
If water is concentrated at mating points in conventional systems, then drainage function is achieved, but structural integrity deteriorates due to water intrusion
Solution Approach 1:
The patent removes the problematic mating points between separate components by integrating them into a single piece. The continuous structure eliminates the interfaces where water could concentrate and penetrate, thereby protecting structural integrity while maintaining drainage functionality.
