Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual sampling and testing methods are used to determine recyclate content and bio-based content, then measurement precision can be maintained, but loss of time increases significantly
Solution Approach 1:
The patent replaces manual mechanical sampling and laboratory testing with automated near-infrared (NIR) spectroscopy systems. The NIR device automatically captures spectral data from the plastic material, and processing units algorithmically determine recyclate and bio-based content without manual intervention, thereby maintaining measurement precision while dramatically reducing time loss.
Solution Approach 2:
The patent creates a spectral copy of the plastic material's optical properties using NIR spectroscopy. Instead of physically sampling and chemically analyzing the material, the system captures a spectral fingerprint that contains all necessary information about recyclate and bio-based content, enabling rapid non-contact measurement with high precision.
2Loss of information
If comprehensive data on recyclate content and bio-based content is collected and stored, then information completeness improves, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional integrated system where a single NIR spectroscopy device performs multiple functions: capturing spectral data, identifying plastic types, determining recyclate content, calculating bio-based content, and storing comprehensive results. This universal approach consolidates what would otherwise require multiple separate systems into one device, reducing overall complexity while maintaining complete data collection.
Solution Approach 2:
The patent introduces a centralized database and processing unit as an intermediary between the NIR sensor and various applications. This intermediary layer standardizes data collection, storage, and retrieval processes, managing the complexity of comprehensive data handling while providing simplified access to all stakeholders including producers, recyclers, and consumers.
3Measurement precision
If chemical analysis methods are used to determine bio-based content, then measurement precision improves, but loss of substance increases due to sample consumption
Solution Approach 1:
The patent replaces destructive chemical analysis methods with non-contact near-infrared spectroscopy. The NIR system measures the optical properties of the plastic material to determine bio-based content without consuming or altering the sample, thereby maintaining measurement precision while eliminating substance loss.
Solution Approach 2:
The patent creates an optical copy of the material's molecular structure characteristics through NIR spectroscopy. The spectral data captures information about chemical bonds and molecular vibrations that indicate bio-based content, providing accurate measurement without physical consumption of the sampled material.
