Solution Overview

Problem

The mixing of different types of materials in refuse collection bins poses challenges for refuse collection and processing companies, leading to safety concerns and inefficiencies, particularly due to the presence of combustible materials and the need for separate handling of recyclables and non-recyclables.

Innovation Solution

A refuse collection vehicle equipped with sensors, support panels, and actuator systems that analyze refuse characteristics, identify material types, and facilitate sorting and disposal, using actuators to release refuse onto an auger screw for compaction and ejection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If different types of materials are mixed in refuse collection bins, then collection efficiency is improved, but safety concerns increase due to combustible materials and processing difficulties

Engineering Contradiction:
Improvecollection efficiencyVSAvoidsafety concerns
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary sensing and identification of materials in the refuse stream before they are fully mixed in the hopper. Sensors detect material types and characteristics early in the collection process, allowing the system to prepare for appropriate handling while materials are still relatively separated, thus maintaining collection efficiency while identifying safety risks before they become problems.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the refuse stream using sensors that provide real-time feedback about material composition, including detection of combustible materials. This feedback loop allows the system to adjust processing parameters and alert operators to safety concerns while maintaining efficient collection operations.

Inventive Principle:
Principle #23Feedback

2Reliability

If sensors and actuator systems are added to enable material identification and sorting, then contamination is reduced and safety is improved, but device complexity increases

Engineering Contradiction:
Improvecontamination reductionVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses multi-functional sensors that can detect multiple material properties (composition, moisture, combustibility) simultaneously, rather than requiring separate sensors for each property. The actuator system is designed to perform multiple functions including sorting, ejecting, and compacting materials based on sensor inputs, reducing overall system complexity while maintaining high reliability for contamination reduction.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If refuse materials are sorted and separated, then processing efficiency is improved, but the complexity of the collection system increases

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments the refuse stream into different material categories using sensors that identify material types and actuators that direct different materials to different destinations. This segmentation occurs in stages, with initial broad categorization followed by more specific sorting, allowing processing efficiency to improve while managing system complexity through hierarchical organization of sorting functions.

Inventive Principle:
Principle #1Segmentation

AI summary

A refuse collection vehicle includes a packer system with an auger screw, one or more refuse support panels, one or more sensing devices, and a refuse support panel actuator system. The refuse support panel(s) support refuse while characteristics of the refuse are sensed. The refuse support panel actuator system moves the refuse support panels such that refuse is released from the refuse support panels in to the packer system. A driver of the packer system rotates the auger screw such the refuse is packed into a storage compartment of the vehicle.
