Composter Environment Adjustment to Prevent Mildew and Odor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current composters are inconvenient to use, as they require manual intervention after composting is complete, leading to potential mildew and odor issues due to incomplete degradation of kitchen waste.
Innovation Solution
A composter system that automatically performs composting operations when kitchen waste is added and adjusts the environment according to predefined conditions to ensure continuous composting, preventing waste from rotting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the composter stops working after completing a composting operation, then energy consumption is reduced, but the kitchen waste may produce mildew and odors due to incomplete degradation
Solution Approach 1:
The composter performs a preliminary environment adjustment after composting completion, modifying the storage cavity conditions (temperature, humidity, oxygen) to prevent mildew and odor before the user removes the waste. This preliminary action ensures complete degradation without requiring continuous energy consumption.
Solution Approach 2:
The system implements periodic environment adjustment operations at specific time intervals after composting completion, rather than continuous operation. This periodic approach balances energy savings with effective prevention of harmful factors like mildew and odor.
2Device complexity
If the user manually takes out kitchen waste after composting, then the composter structure is simple, but the ease of operation is reduced
Solution Approach 1:
The composter automatically detects composting completion and performs environment adjustment operations without requiring user intervention. The system serves itself by monitoring its own state and executing necessary actions, improving ease of operation while maintaining relatively simple structure.
Solution Approach 2:
The composter uses sensors to detect composting completion and provides feedback to the control system, which then automatically adjusts the environment. This feedback mechanism enables automatic operation without complex user interfaces or manual monitoring.
3Reliability
If the composter operates continuously without stopping, then kitchen waste degradation is complete, but energy consumption increases
Solution Approach 1:
The composter operates in periodic cycles: active composting phase followed by a stopping phase with environment adjustment. This periodic operation ensures complete degradation during the active phase while reducing energy consumption during the stopping phase, achieving both reliability and energy efficiency.
Solution Approach 2:
Before stopping the main composting operation, the system performs preliminary environment adjustment to ensure degradation completion. This preliminary action allows the system to stop earlier without compromising reliability, thereby reducing overall energy consumption.

AI summary
The present application provides a waste disposal method that is applied to a composter including a storage cavity. The waste disposal method includes performing a first composting operation in response that first kitchen waste has been added into the storage cavity. Once the first composting operation is stopped, an internal environment of the storage cavity is adjusted to meet a composting condition of the first kitchen waste by performing an environment adjustment operation on the storage cavity according to a first time interval.
