Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Common trash receptacles emit foul odors and accelerate the spoiling of organic waste due to moisture and enclosed environments, leading to increased waste production and odor issues.
Innovation Solution
A storage device with a removable bin, recirculation fan, ozone generator, exhaust fan, and filter system that circulates air, disperses ozone, and maintains negative pressure to reduce spoilage and odor, featuring a controller to adjust fan speeds and ozone levels based on environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If organic waste is stored in an enclosed trash receptacle, then the waste is contained and organized, but foul odors are emitted and spoilage is accelerated due to moisture accumulation
Solution Approach 1:
The patent employs an ozone generator that introduces ozone (O3) into the storage bin to chemically oxidize and neutralize odor-producing chemicals and bacteria on organic waste. The ozone reacts with harmful compounds to break them down, effectively eliminating odors while the exhaust system maintains negative pressure to prevent odor escape.
Solution Approach 2:
The system uses pneumatic principles through the exhaust fan that creates negative pressure within the storage bin relative to the surrounding environment. This pressure differential ensures that air and odors are drawn into the bin through intake ports and filtered before exhaust, preventing odor emission while maintaining proper airflow circulation.
2Reliability
If air is circulated throughout the bin to reduce moisture and spoilage, then waste preservation is improved, but energy consumption increases due to continuous fan operation
Solution Approach 1:
The recirculation fan operates periodically rather than continuously, cycling air through the bin at intervals to maintain proper circulation and moisture control. This periodic operation reduces energy consumption while still achieving the goal of waste preservation through regular air movement and moisture removal.
Solution Approach 2:
The controller monitors conditions within the storage bin and adjusts fan operation accordingly, activating the recirculation fan only when needed to maintain proper air circulation and moisture levels. This feedback-based control optimizes energy usage by avoiding unnecessary fan operation while ensuring waste preservation requirements are met.
3Object-affected harmful factors
If ozone is dispersed into the bin to chemically react with odor-producing chemicals, then odor elimination is improved, but ozone concentration control becomes critical to avoid safety issues
Solution Approach 1:
The controller regulates ozone generator operation to maintain appropriate ozone concentrations within the storage bin, using feedback control to prevent both insufficient odor elimination and excessive ozone accumulation that could create safety hazards. The system adjusts ozone generation based on operational conditions and duration.
Solution Approach 2:
The ozone generation operates continuously during storage periods to maintain consistent odor elimination effectiveness, with the controller ensuring uninterrupted ozone dispersal throughout the bin to continuously neutralize odor-producing chemicals on the organic waste.
4Object-affected harmful factors
If a filter is positioned in the exhaust flow path to remove particles, then air quality is improved, but pressure drop increases reducing exhaust efficiency
Solution Approach 1:
The exhaust system is designed to operate under negative pressure conditions, with the exhaust fan creating sufficient pressure differential to overcome the resistance introduced by the filter. The pneumatic design ensures that the negative pressure gradient drives air through the filter effectively, maintaining both air quality and exhaust efficiency.

AI summary
In general, this disclosure relates to an apparatus that reduces spoilage and the associated odors using two methods. First, air is circulated into, throughout, and out of the storage device, removing moisture and reducing the rate at which the organic matter spoils. Second, an ozone generator converts oxygen into ozone, which chemically reacts with the organic waste and odor producing chemicals within the device, reducing the discernible odor.
