Splash Plate with Baffle Perforations for Erosion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing splash plates for leaching chambers are ineffective in preventing soil erosion when waste water is introduced at varying flow rates, leading to potential clogging of drain holes and instability of the chamber due to unpredictable water landing points and increased erosion.
Innovation Solution
A splash plate design featuring a base panel and upright side portions that secure to the end cap to inhibit movement, combined with a baffle portion with integrated perforations to manage water flow and prevent erosion, ensuring consistent water contact and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a flat splash plate is placed on the soil to prevent erosion, then soil erosion is reduced, but the splash plate moves or floats due to water force
Solution Approach 1:
The splash plate is divided into multiple segments or sections that can independently adjust to water flow forces, preventing the entire plate from moving while maintaining coverage for erosion prevention
Solution Approach 2:
Weighting elements or anchoring mechanisms are added to the splash plate to counterbalance the buoyant and hydrodynamic forces exerted by flowing water, keeping the plate stable on the soil surface
2Stability of the object's composition
If the splash plate is secured to prevent movement, then position stability is improved, but water flow distribution becomes uneven
Solution Approach 1:
The splash plate incorporates variable geometry features such as varying hole sizes, shapes, or densities in different regions to compensate for water flow patterns, ensuring uniform distribution across the plate surface despite fixed positioning
Solution Approach 2:
The splash plate uses curved or domed surfaces instead of flat planes to naturally distribute water flow more evenly across the surface, with the curvature helping to redirect water toward areas that need additional flow
3Ease of manufacture
If the splash plate covers a small area, then it is easier to install and position, but water projects beyond the plate causing erosion
Solution Approach 1:
The splash plate design extends coverage in the vertical dimension through upright sides or walls, creating a three-dimensional structure that intercepts water flow before it reaches the soil, effectively increasing protection area without complicating horizontal installation

Function Achieved in This Case
The solution effectively mitigates soil erosion by ensuring consistent water contact and distribution, preventing clogging and chamber instability, even with varying water flow rates.
Implementation Method 1
waste water being introduced into the end cavity contacts the base panel
Implementation Method 2
a baffle portion with integrated perforations to manage water flow and prevent erosion, ensuring consistent water contact and distribution

AI summary
A splash plate for use with an end cap or end portion of a chamber is provided, wherein the end cap or end portion defines an end cavity having an open end cavity bottom and includes an opening for containing a waste water pipe that introduces waste water into the end cavity. The splash plate includes a base panel for covering the end cavity bottom such that waste water introduced into the end cavity contacts at least a portion of said base panel and a means for positionably securing the splash plate relative to the end cap or end portion.
