Solution Overview

Problem

Current used-material collection systems face inefficiencies such as mixed material streams, contamination, incomplete container filling leading to unnecessary transportation costs, lack of separate weighing, and inadequate data tracking for user reimbursement, resulting in suboptimal resource management and limited data availability.

Innovation Solution

A system and method for collecting, processing, and transferring segregated used-materials using a product collection vehicle equipped with a product collection module and transfer module, which includes an end effector to manipulate and align storage containers, ensuring accurate weighing and data tracking through a computer system, and integrating RFID technology for identification and communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If collection is performed on a fixed schedule, then collection operations are simple to manage, but transportation costs increase due to partially filled containers

Engineering Contradiction:
Improvecollection management simplicityVSAvoidtransportation cost
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The system transitions from fixed-schedule collection to dynamic on-demand collection. Collection vehicles are dispatched based on real-time container fill-level data transmitted via RFID tags and received by the central controller, allowing collection operations to adapt dynamically to actual material accumulation rates and optimize vehicle routing.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements continuous feedback through RFID tags that automatically transmit container fill-level information to the central controller. This feedback loop enables the controller to monitor material accumulation in real-time and trigger collection operations only when containers reach optimal fill levels, eliminating unnecessary trips and optimizing transportation efficiency.

Inventive Principle:
Principle #23Feedback

2Quantity of substance

If mixed material streams are collected, then collection coverage is maximized, but material contamination and processing difficulty increase

Engineering Contradiction:
Improvecollection coverageVSAvoidmaterial contamination
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The system divides the collection process into separate streams using multiple PSCs (processed used-material containers) at each collection point, each dedicated to a specific material type. This segmentation prevents contamination between different material streams while maintaining comprehensive collection coverage across multiple material categories.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each PSC is specifically designed and designated for collecting a particular type of processed used-material with specific properties. This local quality approach ensures that each container maintains material purity by being dedicated to a single material stream, while the overall system achieves broad collection coverage through the network of specialized containers.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If containers are emptied on a fixed schedule, then operational simplicity is maintained, but transportation expenses increase due to unnecessary trips with partially filled containers

Engineering Contradiction:
Improveoperational simplicityVSAvoidtransportation expense
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

RFID tags continuously monitor and transmit container fill-level data to the central controller, creating an automated feedback system that triggers collection operations only when containers reach optimal fill levels. This eliminates unnecessary trips while maintaining simple centralized control through the controller's automated dispatch decisions.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The containers perform self-monitoring of their fill levels through integrated RFID tags that automatically detect and communicate material accumulation status. This self-service capability eliminates the need for manual inspection while enabling optimized collection timing based on actual container status rather than fixed schedules.

Inventive Principle:
Principle #25Self-service

4Device complexity

If separate weighing of materials is not implemented, then system complexity is reduced, but accurate data tracking for user reimbursement becomes impossible

Engineering Contradiction:
Improvesystem complexityVSAvoidweight data accuracy
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The weighing system is segmented into separate weighing mechanisms for each material stream, with each PSC having its dedicated weigh scale. This segmentation enables accurate individual weight measurement for each material type while maintaining manageable system complexity through modular, distributed weighing stations rather than a single complex centralized system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The central controller acts as an intermediary that receives weight data from multiple distributed weigh scales via RFID communication. This intermediary role allows the system to maintain simple local weighing operations at each collection point while achieving centralized data aggregation and accurate total weight tracking for reimbursement purposes.

Inventive Principle:
Principle #24Intermediary (Mediator)
