Waterproof Bag Steam Cleaning for Splash-Free Urban Waste Bins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste bin cleaning systems using pressurized water cause significant water consumption, splashing, and inconvenience to pedestrians, and are limited by compressor failures and unsuitability for narrow spaces.
Innovation Solution
A cleaning equipment with a waterproof bag and steam applicator, combined with a brush and vacuum, allows for effective cleaning without tilting the bin, reducing water usage and preventing splashes, and includes a compact design for maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pressurized water cleaning system is used, then cleaning effectiveness is improved, but water consumption increases and splashing occurs
Solution Approach 1:
A flexible waterproof bag is placed over the waste bin to create a contained cleaning environment. The bag conforms to the bin's shape and allows the applicator to move freely while preventing water escape, thus maintaining cleaning effectiveness while eliminating splashing and reducing water consumption.
Solution Approach 2:
The waterproof bag acts as an intermediary between the cleaning system and the external environment. It mediates the cleaning process by containing the water and steam within the bin while allowing the applicator to penetrate and deliver the cleaning agents effectively.
2Power
If pressurized water gun is used, then cleaning power is improved, but inconvenience to pedestrians increases due to splashes
Solution Approach 1:
The waterproof bag creates a physical barrier that contains all water and steam within the waste bin, preventing any splashes from reaching pedestrians. This allows the use of powerful cleaning agents without exposing the surrounding environment to harmful water spray.
3Power
If vehicle-mounted cleaning system is used, then cleaning capability is improved, but accessibility to narrow spaces is reduced
Solution Approach 1:
The cleaning system is segmented into portable components: a handheld applicator, a separable waterproof bag, and a removable collection bag. This segmentation allows the system to be easily transported and operated in narrow spaces without requiring a large vehicle.
Solution Approach 2:
The heavy vehicle-mounted mechanical system is replaced with a lightweight portable system using an extendable pole for the applicator and manual positioning of the waterproof bag, enabling operation in confined areas that vehicles cannot access.
4Manufacturing precision
If tilting waste bins is used, then dirt removal is improved, but operational complexity increases
Solution Approach 1:
Instead of tilting the bin to facilitate cleaning, the approach is inverted: the waterproof bag is placed over the upright bin, and the applicator delivers cleaning agents directly into the bin through the bag. This eliminates the need to tilt or empty the bin while maintaining effective dirt removal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Achieves efficient cleaning with minimal water and disinfectant use, silent operation, and access to narrow areas, while protecting pedestrians from splashes and enhancing cleaning efficacy.
Implementation Method 1
a steam applicator element (5) and/or sprayer, suitable for introducing water vapor and/or spraying water mixed with cleaning and/or disinfection products into the interior of a waste bin (3)
Implementation Method 2
a brush (8) with radial bristles to scrub the inside of the waste bin (3)
Implementation Method 3
a vacuum cleaner (9) with an interchangeable suction nozzle (10) to equip it with a brush or not, with which the crossbar and support legs of the bin are scrubbed, at the same time vacuuming up any solid and liquid waste

AI summary
Disclosed is a cleaning device for urban waste bins and the like, which comprises at least: a bag (2) of waterproof material of a size suitable for covering the top of a waste bin (3) to be cleaned and which has an access opening (4) at the bottom (2a), which opening, once the bag (2) has been placed covering the waste bin (3), is situated at the top and is suitable for the passage of a handle of a steam applicator element (5); a steam applicator element (5) and/or sprayer, suitable for introducing steam and/or spraying water mixed with cleaning and/or disinfectant products, from a liquid-containing tank (6) provided with means (7) for producing the steam and/or spraying; and a radial-bristle brush (8) for scrubbing the inside of the waste bin (3). Preferably, the waterproof bag (2) is reusable and extendable, such that its dimensions can be adapted to different sizes of waste bin (3).
