Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for introducing high-pressure water flow into sewage systems during flood events often damage infrastructure, require multiple hose lines, and lack efficient solutions for connecting hoses without kinking or displacing them, leading to safety and operational challenges.
Innovation Solution
A transportable deflection device with a hollow body and orthogonal inlet openings that reduces jet power through diffusion elements, allowing for safe and efficient introduction of liquid into horizontal manhole openings, featuring a fixing device to secure the device and prevent displacement, and connection devices for easy hose management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple hose lines are inserted into a standard street drain to handle large water flow, then the water flow capacity is improved, but the hoses are kinked and disrupted, causing flow impairment and potential damage
Solution Approach 1:
The device segments the single drain opening into multiple inlet openings (at least two) that distribute water flow across different pathways, allowing multiple hose lines to enter without kinking while maintaining smooth flow through each individual pathway
2Reliability
If hoses are weighted down with sandbags to prevent displacement under high pressure, then the hoses remain in place, but the flow is further impeded
Solution Approach 1:
The device acts as an intermediary structure that receives high-pressure water flow and distributes it through multiple inlet openings, eliminating the need for sandbags while maintaining hose position stability and preserving flow efficiency through proper flow distribution
3Object-affected harmful factors
If the hollow body includes diffusion elements to reduce jet power, then infrastructure damage is prevented, but the device complexity increases
Solution Approach 1:
The diffusion elements are applied locally at the inlet openings where water enters the hollow body, reducing jet power only at critical impact points while maintaining the overall simplicity of the hollow body structure
