Under-sink Waste Composter with Segmented Auger and Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste management systems face challenges in treating large amounts of ground garbage at water treatment plants and septic systems, leading to increased costs and inefficient composting, as typical garbage disposals do not effectively recycle organic waste.
Innovation Solution
An under-sink waste composter appliance with rotating augers and removable screens that convey and process waste water, incorporating heaters and fans to facilitate composting and reduce waste downstream, allowing for efficient recycling and compost production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a typical garbage disposal is used to ground waste, then waste can be discharged through existing drainpipes, but large amounts of ground garbage burden water treatment plants and septic systems, increasing treatment costs and reducing composting efficiency
Solution Approach 1:
The waste stream is segmented into two paths: liquid waste goes to the drainage system while solid organic matter is diverted to the composter. The screen separates these components, allowing efficient routing of each material type to its appropriate destination.
Solution Approach 2:
Organic composting material is extracted from the ground waste stream by the screen before it enters the drainage system. This extracted material is then conveyed by the auger to the composter, preventing it from burdening treatment plants.
2Device complexity
If ground garbage is discharged to water treatment plants, then waste management is simplified, but treatment costs increase and composting opportunities are lost
Solution Approach 1:
The system performs self-service by automatically separating and composting organic material at the source (kitchen sink), eliminating the need for expensive external water treatment of this material. The composter handles its own processing without requiring treatment plant infrastructure.
3Adaptability or versatility
If a composter appliance is added downstream of the sink, then recycling and composting are improved, but the device complexity and installation requirements increase
Solution Approach 1:
The appliance combines multiple functions in one unit: the screen filters waste, the auger conveys material, and the composter processes organic matter. This multi-functional integration achieves versatile waste recycling while consolidating components to reduce overall complexity.
Solution Approach 2:
The auger is nested within the composter housing, and the screen is positioned within the waste stream path above the auger. This nested arrangement compactly integrates multiple components vertically, fitting within standard under-sink spaces without requiring excessive horizontal or vertical clearance.
4Loss of substance
If screens are used to separate waste materials, then composting material is recovered, but screen cleaning and maintenance become necessary
Solution Approach 1:
The screen is made removable and extractable from the composter assembly, allowing users to easily take it out for cleaning without disassembling the entire device. This extraction capability significantly simplifies maintenance operations.
Solution Approach 2:
The auger acts as an intermediary that continuously moves material past the screen, preventing material buildup that would make cleaning difficult. By keeping the screen surface clear through active conveyance, the cleaning task becomes simpler and less frequent.
