Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Garbage collection rooms in high-rise buildings pose health risks due to concentrated airborne proteins and pollutants, which are not effectively addressed by existing waste management systems, leading to potential respiratory illnesses and environmental degradation.
Innovation Solution
An automated air evacuation system that uses an air quality sensor to detect threshold values, activates a UV light chamber to kill bacteria and fungi, and a fluid filtration system to collect and filter out particulates, ensuring safe air quality before release into the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual fan activation is used to evacuate air, then air evacuation can be performed, but health risks from concentrated airborne proteins remain and response is delayed
Solution Approach 1:
The air quality sensor continuously monitors airborne protein concentrations in advance, detecting pollution levels before they reach dangerous thresholds. This preliminary detection triggers automated fan activation proactively, eliminating the delayed manual response and preventing health risks before they materialize.
Solution Approach 2:
The system establishes a closed-loop feedback mechanism where the air quality sensor continuously monitors airborne protein levels and provides real-time data to the control system. When concentrations exceed predetermined thresholds, the feedback loop automatically activates the evacuation fan, creating a responsive automated system that continuously adjusts based on actual air quality conditions.
2Device complexity
If air is evacuated directly without filtration, then air evacuation is simple, but pollutants are released into the environment causing environmental degradation
Solution Approach 1:
The air evacuation system is segmented into distinct functional stages: a first evacuation fan for initial air removal, a filtration system with HEPA and carbon filters for pollutant removal, and a second evacuation fan for controlled release. This segmentation allows each component to perform its specific function efficiently, maintaining system simplicity while eliminating harmful pollutants before environmental release.
Solution Approach 2:
The filtration system acts as an intermediary between the garbage collection room and the external environment. Pollutants are first evacuated by the initial fan, then passed through the filtration system where particulate and gaseous contaminants are removed, and only cleaned air is released by the second fan. This intermediary filtration stage prevents direct pollutant release while maintaining system manageability.
3Object-affected harmful factors
If complex multi-stage filtration is implemented, then air quality improves, but device complexity and cost increase
Solution Approach 1:
The filtration system is divided into two specialized stages: a HEPA filter section for particulate matter removal and an activated carbon filter section for gaseous contaminant adsorption. Each filter type addresses specific pollutant categories, allowing the system to achieve comprehensive air quality improvement through modular, targeted filtration rather than a single complex system.
Solution Approach 2:
The filtration system is designed to handle multiple types of pollutants simultaneously using different mechanisms: the HEPA filter captures particulate matter through physical filtration, while the activated carbon filter adsorbs gaseous contaminants through surface adsorption. This multi-functional approach enables a single integrated system to address diverse air quality issues without requiring separate specialized systems for each pollutant type.

AI summary
This description relates to waste disposal garbage chutes and more particularly to automated air quality management in and around the disposal chute and collection rooms where garbage chutes are present utilizing automated air quality sensing hardware and evacuation devices to provide a clean, sanitary waste room environment. A system according to the present invention includes a 3 step design using an air sensor to determine air cleaning cycle, and an air intake port with specular reflective surfaces in the inside to provide a reflective element to reflect UV light into the airborne particulates thereby killing 99% of the bacteria and fungi before entering an electrified gravity fed fluid filament air filter which collects the dead bacteria and fungi and settles in a collection reservoir. The fluid in the reservoir is then further filtered to clean the fluid for reuse in the automated air cleaning system.
