Leakage Water Separation Trunk for Waste Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current urban waste collection systems lack an effective method for separating and retaining liquids from waste deposits, leading to liquid accumulation at the bottom of containers and potential leakages during collection, necessitating impractical cleaning and suction methods.
Innovation Solution
A device comprising an impervious PVC inner bag attached to an aluminium ring with stainless steel loops, a polyethylene rope, and a ClamCleat-type cable fast trapping mechanism, along with pulleys and loops, allows for the separation and retention of liquids within a semi-buried polyethylene container, enabling separate handling and transport of liquids and solids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no liquid separation device is used, then the collection system is simple, but liquid accumulation occurs at the bottom of containers causing leakage and requiring frequent cleaning
Solution Approach 1:
The collection bag is divided into two functional zones: an upper solids retention area and a lower liquids retention trunk. This segmentation allows separate containment and handling of liquids and solids, preventing liquid leakage while maintaining operational simplicity through a single integrated bag structure.
Solution Approach 2:
The liquids retention trunk is nested within the collection bag, with the trunk forming an internal cavity at the bottom portion. This nested structure enables liquid separation without adding external components, maintaining system simplicity while achieving reliable liquid containment.
2Ease of operation
If traditional suction pumps are used for cleaning, then liquid deposits can be removed, but the process is impractical and requires frequent intervention
Solution Approach 1:
The liquids retention trunk can be extracted as a separate component from the collection bag. This allows the liquid-containing trunk to be removed and emptied independently, making liquid removal practical and significantly reducing the frequency of cleaning operations required.
Solution Approach 2:
The collection system transitions from a static single-chamber bag to a dynamic two-zone structure where the liquids trunk can be independently manipulated. This dynamic design enables easy access and emptying of liquids without disturbing the solids portion, improving operational ease.
3Reliability
If liquids and solids are transported together, then single transport is simple, but liquid leakage occurs during collection and transport operations
Solution Approach 1:
The collection bag segments liquids and solids into separate zones, with the liquids retention trunk at the bottom and solids retention area above. This segmentation prevents liquid leakage during transport by containing liquids in a dedicated sealed trunk, while the separation mechanism remains integrated within the single bag structure.

AI summary
This invention relates to a device intended for separating and retaining leakage water, which is to be placed inside urban solid waste containers (but which can be extracted/moved), the said device comprising an impervious bag (2) in PVC canvas, having in its lower end a kind of "Trunk" (5) whereby and whereto the liquids originating from the deposited refuse, or the liquids that have already been introduced in that form, i.e. the so-called lixiviates, will flow and accumulate, the said bag being within an outer bag (1). The motion of the aforementioned trunk (5) is controlled by means of a set comprising eight eyelets (8) which are sewed next to the lower end of the said trunk, wherein a polyethylene cable (6) is passed through and controlled by the system's operator with the aid of a cable fast trapping system (3) as well as of a set of pulleys and loops (7), which is positioned at the top of the bag and fixed to the aluminium ring supporting the impervious bag/sleeve (6).
