Mobile Waste Container Compaction for Higher Transport Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dumpsters are inefficient in transporting bulky waste due to high void volumes, requiring multiple dumpster sizes, leading to underutilization of trucks and increased operational costs, and necessitate frequent replacement and transport of empty dumpsters, which is time-consuming and costly.
Innovation Solution
A mobile waste collection and compaction system comprising a waste collection container with a roller compactor that compacts waste material to increase density, allowing for more efficient loading and transport of waste material in a single trip, using a single truck, and enabling the use of smaller, less expensive containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional dumpsters are used to transport bulky waste, then the waste can be collected and transported, but the void volumes are high resulting in inefficient transport and increased operational costs
Solution Approach 1:
The patent applies preliminary action by compacting the waste material before transport. The compactor device is used to compress waste in the dumpster prior to pickup, increasing the density and mass of waste that can be transported in a single trip, thereby improving transport efficiency and reducing the number of trips required
Solution Approach 2:
The patent changes the physical parameter of waste density through compaction. By applying mechanical compression to the waste material, the density increases from a low-density bulky state to a high-density compacted state, allowing more waste mass to be transported in the same volume
2Adaptability or versatility
If multiple dumpster sizes are offered to accommodate different customers, then various waste collection needs are met, but truck utilization is underoptimized and operational costs increase
Solution Approach 1:
The compaction capability is established in advance at the customer site, allowing the dumpster to be filled to its maximum capacity with compacted waste. This preliminary compaction ensures that regardless of dumpster size, the truck can efficiently transport near-maximum waste mass, optimizing truck utilization while maintaining flexibility in dumpster selection
Solution Approach 2:
The system enables self-service compaction at the customer location through the portable compactor device. The customer or operator can compact waste in the dumpster before pickup without requiring specialized truck equipment, allowing flexible dumpster sizing while ensuring optimal waste density for transport
3Reliability
If empty dumpsters are frequently transported and replaced to meet waste collection demands, then service continuity is maintained, but time and operational costs increase
Solution Approach 1:
Waste is compacted in advance in the dumpster before it becomes full, extending the time between pickups and replacements. This preliminary compaction allows the same dumpster to remain in service longer, reducing the frequency of replacements and the associated time losses while maintaining continuous waste collection capability
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
The system enhances operational efficiency by increasing the mass of waste transported per trip, reducing operational and capital costs, and allowing for versatile waste collection from multiple locations without needing to transport empty containers, thus optimizing truck utilization and minimizing waste compaction trips.
Implementation Method 1
a roller compactor configured to compact the waste material in the waste collection container to increase a density of the waste material within the waste collection container

AI summary
A mobile system used for collecting, compacting, and transporting waste material from a waste generating site. The mobile system includes a waste collection container for holding the waste material therein and a roller compactor for compacting the waste material in the waste collection container to increase a density of the waste material within the waste collection container relative to a density of the waste material in the waste container. The mobile system can also have a transport truck, the waste collection container being attachable to the transport truck.
