Square-U Drain Channel With Slanted Grating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage installations in warehouses and factories with flat grating at the surface level often fail to effectively manage water flow during washdown operations, leading to water bouncing back and inadequate drainage, especially under heavy traffic conditions.
Innovation Solution
A drainage channel system with flat grating and precision-cut, stainless steel feet that are anchored to the floor using threaded rods, featuring a square-U shape with apertures for cement injection and venting, and slanted slats to deflect water towards a drain downpipe, ensuring efficient water flow and stability under foot and vehicle traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional drainage installations are used with flat grating at surface level, then the drainage system is simple to install, but water flow is not effectively managed during washdown operations causing water to bounce back
Solution Approach 1:
The drainage channel is divided into distinct functional segments: a reception area with flat grating at surface level, a sloped transition section, and a collection area with vertical walls. This segmentation allows water to be effectively guided through each zone, preventing backflow while maintaining structural manageability
Solution Approach 2:
The drainage channel utilizes three-dimensional spatial arrangement by creating vertical walls that rise from the floor level and forming a sloped transition zone. This dimensional approach directs water flow downward and forward into the channel, eliminating the bouncing back issue without requiring overly complex surface-level structures
2Stability of the object's composition
If precision-cut stainless steel feet are used for anchoring the drainage channel, then stability under foot and vehicle traffic is improved, but manufacturing complexity increases
Solution Approach 1:
The stainless steel feet are pre-cut with precise angles and dimensions during manufacturing, allowing them to be directly anchored to the floor without requiring complex on-site fabrication or adjustment. This preliminary precision work ensures stable anchoring while simplifying installation
Solution Approach 2:
The feet are designed with specific geometric parameters (angles, lengths, thicknesses) that optimize both structural strength and anchoring capability. By carefully selecting these parameters, the design achieves high stability under traffic loads while maintaining manufacturability through standardized precision cutting
3Productivity
If slanted slats are used to deflect water towards drain downpipe, then water flow direction control is improved, but grating complexity increases
Solution Approach 1:
The slanted slats are arranged in a curved or arched pattern within the grating, following the natural flow path of water. This curved configuration efficiently directs water toward the drain downpipe while maintaining a relatively simple grating structure that can be manufactured as a single piece or modular sections

Function Achieved in This Case
The system effectively directs high-pressure washwater into the drainage channel, preventing backflow and ensuring reliable water management, even under heavy traffic conditions, by using monolithic, food-grade cast grating sections and adjustable feet for secure anchoring.

AI summary
A drainage installation (20), for a warehouse and/or factory floor that has a surface level (26), has a drainage channel (24) recessed into the floor and a plurality of sections of flat grating (22) seated inside the drainage channel (24). The drainage channel (24) has an axially-elongated, square-U shaped channel portion which is flanked by horizontal shoulders (30), which then transition into vertically-depending skirt portions (32). The horizontal shoulders (30) as well as the sections of flat grating (22) are arranged to be more less planar with the surface level (26). Wherein, the skirt portions (32) are formed with a series of apertures (36) which either allow the injection of wet cement underneath the shoulder portions (30) of the drainage channel (24), or alternately the venting of the wet cement when the cavity under the shoulder portions (30) are over-filled.
