Solution Overview

Problem

Current systems for tracking and recycling milled material lack efficient methods to associate material properties with storage locations, leading to inefficiencies in the recycling process.

Innovation Solution

A system utilizing a first detection device on the milling machine to record data signals related to the milled material and a second detection device, such as a GPS-enabled device, to capture position data of the storage location, with both sets of data being transmitted to a documentation device for linkage, allowing for precise tracking and recycling options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If material properties are determined at the storage location, then recycling accuracy is improved, but time consumption and process complexity increase

Engineering Contradiction:
Improvematerial property identification accuracyVSAvoidtime for re-determination at storage location
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary detection and documentation of material properties at the milling source using the first detection device before the material is transported. This advance action eliminates the need for re-determination at the storage location, directly resolving the contradiction by capturing material properties upfront while the material is still being processed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The documentation device serves as an intermediary that receives and stores material property data from the first detection device, then provides this information at the storage location without requiring re-measurement. This mediator transfers the material property information across the spatial and temporal gap between milling and storage, eliminating time loss.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If material properties are tracked from milling to storage, then recycling efficiency is improved, but system complexity increases

Engineering Contradiction:
Improverecycling efficiencyVSAvoiddetection and documentation system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The documentation device performs multiple functions: it receives material property data from the first detection device, stores this information, and provides it at the storage location. This multi-functional approach consolidates what could be multiple separate systems into a single device, improving recycling efficiency while limiting the increase in overall system complexity.

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

Solution Approach 2:

The system automatically tracks and documents material properties without requiring manual intervention. The detection devices and documentation device work autonomously to establish the link between milled material and storage location, improving recycling efficiency through automation while keeping the complexity manageable through self-service operation.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If position data is recorded with a second detection device, then storage location identification is improved, but system complexity and cost increase

Engineering Contradiction:
Improvestorage location identification accuracyVSAvoiddetection device quantity and system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The detection system is segmented into specialized devices with specific functions: the first detection device handles material property detection, while the second detection device handles position data recording. This segmentation allows each device to be optimized for its specific task, improving storage location identification accuracy while keeping individual device complexities low.

Inventive Principle:
Principle #1Segmentation
