Roof Scupper Overflow Sensor for Debris Blockage Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roof scuppers and drains often become obstructed due to debris accumulation, leading to reduced water removal efficiency, potential roof damage, and lack of notification to building owners or tenants about system malfunctions, which can result in undetected flooding and structural integrity issues.
Innovation Solution
A roof scupper overflow device with a sensor system that includes a sieve tray, buoy, and magnetic switches, which detects rising water levels and triggers an alert via text message and email when the primary drainage system is compromised, allowing for timely maintenance and preventing flooding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strainer or grating structure is installed in the roof scupper to prevent debris obstruction, then the risk of blockage is reduced, but the device complexity increases and maintenance difficulty increases due to debris accumulation on the strainer
Solution Approach 1:
The patent extracts the strainer/grate component from the scupper system and replaces it with a sensor-based detection system. Instead of physically blocking debris with a strainer, the invention uses sensors to detect water level rise that indicates blockage, then notifies maintenance personnel. This eliminates the complex strainer structure while maintaining drainage reliability through early detection and alert mechanisms.
Solution Approach 2:
The patent implements a feedback system using water level sensors that continuously monitor the scupper outlet. When debris causes water level to rise above a threshold, the sensor triggers an alarm or notification system that provides real-time feedback to maintenance personnel. This feedback mechanism allows the system to detect and respond to blockages without requiring physical strainers, thereby reducing structural complexity while maintaining reliability.
2Loss of information
If conventional roof scuppers are used without sensor systems, then the device complexity is low, but the loss of information occurs as building owners are not notified when the drainage system is compromised
Solution Approach 1:
The patent implements a feedback system using water level sensors that continuously monitor the scupper outlet. When debris causes water level to rise above a threshold, the sensor triggers an alarm or notification system that provides real-time feedback to maintenance personnel. This feedback mechanism allows the system to detect and respond to blockages without requiring physical strainers, thereby reducing structural complexity while maintaining reliability.
Solution Approach 2:
The patent introduces an intermediary sensor system that acts as a mediator between the physical drainage system and the building owner. The sensors detect water level changes and transmit this information through communication devices (alarms, notifications) to bridge the gap between the silent blockage condition and the informed owner, enabling timely intervention without adding complex mechanical components.
3Productivity
If the scupper opening is left open to allow free water flow, then the water removal efficiency is high, but the object-affected harmful factors increase as large objects can be ingested into the drain plumbing system
Solution Approach 1:
The patent removes the strainer or grating component that would physically block the scupper opening. Instead of using a mechanical barrier to prevent debris ingestion, the invention relies on the open scupper design for maximum water flow while using sensor-based detection to monitor for blockage conditions. This extraction of the strainer maintains high productivity while managing harmful factors through detection and notification rather than physical prevention.
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 effectively prevents debris from clogging the drainage system, ensures continuous water flow by alerting maintenance teams of potential flooding situations, and maintains roof integrity by providing real-time status updates on drainage system functionality.
Implementation Method 1
A foam buoy is disposed within a housing slidable within a frame supported by the base plate... Floating of the foam buoy raises the screen and sieve plate attached thereto
Implementation Method 2
The WIFI sensor module is supported on top of the top bar... a pair of spaced apart opposing magnetic switches affixed to a top surface of the inner edge portion of the base which hold the sieve plate thereto

AI summary
The roof scupper overflow with sensor cooperatively engages and replaces a conventional roof opening through a wall or in a corner to prevent trash from reaching and clogging the conventional roof basket and drain. Accumulating trash builds up on the screen of the roof scupper overflow causing a foam float or buoy connected to a trash tray to rise permitting water to run under the trash trap at roof level. The trash tray is retained to a base with magnets. When the water reaches a predetermined level, the foam buoy rises pulling the trash tray away from the base allowing water to flow to the conventional roof drain basket and activating a magnet switch sending a signal to overflow sensor and a control module connected to WIFI service.
