Roof Drain Strainer Debris Clearing System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual clearing of debris from roof drain strainers is time-consuming, labor-intensive, and requires regular scheduling, which can lead to clogged drains and water accumulation on flat roofs, potentially causing damage to buildings.
Innovation Solution
A debris clearing system comprising a base member with attachment couplers, a support frame, arm assemblies, a clearing member (such as a brush), and a drive unit (like a motor) that rotates the arm assemblies to clear debris from the drain strainer's exterior surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual clearing of debris from drain strainers is performed, then debris removal is achieved, but time consumption and labor intensity increase
Solution Approach 1:
The system enables automatic self-clearing of the drain strainer through a motorized drive unit that rotates brush assemblies, eliminating the need for manual intervention and allowing the system to maintain itself autonomously
Solution Approach 2:
Manual mechanical clearing operations are replaced with an automated electromechanical system consisting of a motor, drive mechanism, and rotating brush assemblies that perform the clearing function automatically
2Reliability
If manual clearing is performed periodically, then debris accumulates less, but regular scheduling is required and labor is needed
Solution Approach 1:
The automated system performs routine maintenance operations without human intervention, making the system self-maintaining and eliminating the need for scheduled manual labor while ensuring continuous drain functionality
3Productivity
If drain strainer is left unclogged, then water flows properly, but manual clearing is required to prevent clogs
Solution Approach 1:
The manual mechanical clearing process is substituted with an automated electromechanical system that uses a motor-driven rotation mechanism to continuously or periodically clear debris, maintaining water drainage efficiency without human labor
Solution Approach 2:
The system automatically maintains itself by clearing its own strainer, ensuring continuous proper water flow without requiring external manual intervention
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 system automates the debris clearing process, reducing manual labor and scheduling needs, effectively preventing drain clogs and water accumulation on flat roofs, thereby minimizing the risk of building damage.
Implementation Method 1
The clearing member is configured to clear debris from the exterior surface of the drain strainer when the drive unit is operated to rotate the support frame and the at least one arm assembly

AI summary
A debris clearing system for clearing debris from a drain strainer mounted to a roof includes a base member having at least one attachment coupler configured to removably attach the base member to the drain strainer, a support frame rotatably coupled to the base member, at least one arm assembly coupled to the support frame, a clearing member coupled to a distal end of the at least one arm assembly. The clearing member being adjacent the exterior surface of the drain strainer when the base member is coupled to the drain strainer. The system includes a drive unit coupled to the support frame to rotate the support frame and the at least one arm assembly relative to the base member. The clearing member clears debris from the exterior surface of the drain strainer when the drive unit rotates the support frame and the at least one arm assembly.
