Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rainwater purification systems face issues with sediment remobilization and structural complexity, particularly in separation apparatuses with downward flow designs, which hinder efficient filtration and adsorption processes.
Innovation Solution
A separating apparatus with a container featuring a settling and sludge collection chamber below the separating area, utilizing a lower guide plate to distribute liquid radially and guide sediments into the chamber, reducing remobilization and simplifying the structure by integrating distribution and sediment management in a single element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a downward flow design is used in the separating apparatus, then the sedimentation effect is improved, but the turbulence of separated sediments increases causing remobilization
Solution Approach 1:
The separating apparatus is divided into distinct functional zones: an upper separating area for sedimentation and a lower settling chamber for sediment collection. This segmentation allows the downward flow to effectively settle sediments in the upper area while the lower chamber provides a calm zone for sediment accumulation without remobilization.
Solution Approach 2:
A guide plate is introduced as an intermediary element between the separating area and the settling chamber. This guide plate directs the liquid flow smoothly into the settling chamber, reducing turbulence and preventing remobilization of separated sediments while maintaining effective sedimentation in the upper area.
2Productivity
If a funnel-shaped collecting apron is used to collect sediments, then sediment collection is improved, but the structure becomes more complex and difficult to combine with filtration and adsorption
Solution Approach 1:
The guide plate serves multiple functions simultaneously: it directs liquid flow into the settling chamber, defines the boundary between the separating area and settling chamber, and facilitates sediment collection. This merging of functions simplifies the overall structure while maintaining effective sediment collection and enabling integration with filtration and adsorption components.
Solution Approach 2:
The guide plate is designed as a multi-functional element that performs flow direction, separation zone definition, and sediment guidance functions. This universal component replaces the need for a separate funnel-shaped collecting apron, simplifying the structure and enabling better integration with filtration and adsorption systems.
3Manufacturing precision
If the liquid outlet is positioned to maximize sedimentation, then separation efficiency is improved, but liquid distribution uniformity decreases
Solution Approach 1:
The guide plate acts as an intermediary that receives liquid from the outlet and redistributes it uniformly into the settling chamber. This intermediary element maintains the outlet positioning optimized for sedimentation while ensuring uniform liquid distribution through its flow-directing geometry.
Solution Approach 2:
The guide plate creates different flow conditions in different regions: near the outlet, the flow is concentrated for effective sedimentation, while further into the settling chamber, the flow is distributed uniformly. This local variation in flow quality maintains both separation efficiency and distribution uniformity.

Implementation Method 1
a liquid flowing out of the liquid outlet can be guided radially outwards through the lower guide plate in the direction of the inner wall of the container
Implementation Method 2
The separation of sediments from the liquid occurs by gravity. The sediments sink in the liquid.
Implementation Method 3
the liquid separates sediments in the container
