Find Innovative SolutionsGenerate Solutions
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

Engineering Contradictions & Design Principles
Engineering 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
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.
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.
2Quantity of substance
If mixed material streams are collected, then collection coverage is maximized, but material contamination and processing difficulty increase
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.
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.
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
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.
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.
4Device complexity
If separate weighing of materials is not implemented, then system complexity is reduced, but accurate data tracking for user reimbursement becomes impossible
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.
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.
