Frameless Modular Connector Pipe Screen for Stormwater Debris Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash and debris capture devices in storm water drainage infrastructure face challenges such as structural failures due to minimal framing material, clogging of perforations, and inability to withstand water pressure, leading to increased costs and reduced effectiveness in meeting regulatory requirements like withstanding 60 pounds of force.
Innovation Solution
A frameless, modular connector pipe screen device made of perforated stainless steel, bent or rolled into L shapes for reinforcement, allowing for easy assembly and maintenance, and featuring a removable center piece for jetting the outlet pipe without removing the entire system, which can withstand up to 220 pounds of force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional framed CPS devices are used with minimal framing material, then cost is reduced, but structural strength and ability to withstand water pressure deteriorates
Solution Approach 1:
The screen is divided into multiple modular segments that can be assembled together. Each segment is a self-supporting unit with integrated framing, eliminating the need for separate minimal framing material while maintaining structural strength through modular construction
Solution Approach 2:
The device combines perforated screen material with integrated framing elements to create a composite structure that provides both filtration function and structural strength, eliminating the need for separate framing materials
2Ease of operation
If the entire CPS device is removed for jetting the outlet pipe, then thorough cleaning is achieved, but installation time and labor cost increase
Solution Approach 1:
The CPS device is segmented into modular sections where the center piece can be independently removed. This allows maintenance personnel to access and jet the outlet pipe by removing only the center segment rather than the entire device, significantly reducing maintenance time and labor
Solution Approach 2:
The center piece is designed as a removable component that can be extracted from the assembled device. This extraction capability provides direct access to the outlet pipe for jetting operations without requiring removal of the surrounding screen structure
3Ease of manufacture
If flat horizontal screens are used, then manufacturing is simplified, but structural integrity weakens due to direct water flow
Solution Approach 1:
The screen segments are formed with curved surfaces rather than flat planes. This curvature allows water flow to follow the contour of the screen, reducing direct impact forces and improving structural integrity while maintaining manufacturing feasibility through forming processes
4Reliability
If perforated stainless steel is used, then debris capture effectiveness is improved, but cost and manufacturing complexity increase
Solution Approach 1:
The perforated stainless steel screen is divided into multiple smaller modular segments. This segmentation reduces the total amount of complex material handling required during assembly and allows for more manageable manufacturing and installation processes while maintaining the debris capture effectiveness of the perforated material
