Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conveyor belt is used to transport the sampling tape strip, then online monitoring of pollen can be achieved, but vibration occurs during transport causing pollen to shake to adjacent sampling areas and affecting fine collection of pollen concentration
Solution Approach 1:
The sampling tape strip is divided into multiple independent sampling areas, and the invention uses a slide-based system where each slide represents a separate sampling unit. This segmentation prevents pollen from one area from interfering with adjacent areas, resolving the vibration-induced contamination issue while maintaining online monitoring capability.
Solution Approach 2:
The invention replaces the mechanical conveyor belt system with a slide-based automated transfer system. Slides are transferred between sampling areas using a controlled mechanism that minimizes vibration and prevents pollen contamination, while still enabling automated online monitoring.
2Ease of operation
If the sampling tape strip is rolled up after photography, then the tape strip can be stored, but pollen on the tape strip interferes with each other preventing retrieval for reanalysis
Solution Approach 1:
The system uses individual slides instead of a continuous tape strip. Each slide is a discrete sampling unit that can be independently stored and retrieved. This segmentation allows stored slides to remain accessible for reanalysis without interference, maintaining both ease of storage and data traceability.
Solution Approach 2:
The system creates digital copies of pollen samples on slides for analysis and storage. The physical slides serve as permanent, retrievable records that can be accessed for reanalysis, while digital images provide additional data storage and processing capabilities, ensuring data provenance and traceability.
3Productivity
If densely collected pollen is placed on a sampling tape strip, then sampling efficiency increases, but vibration causes pollen to shake to adjacent sampling areas affecting collection accuracy
Solution Approach 1:
The slide-based system divides the sampling area into discrete, isolated zones on each slide. This segmentation allows dense pollen collection in each zone without cross-contamination to adjacent zones, maintaining both high sampling efficiency and accurate concentration measurement.
Solution Approach 2:
The slide acts as an intermediary carrier between the air sampler and the analysis system. It provides a stable, vibration-isolated platform for pollen deposition and transfer, preventing the vibration-induced mixing that occurs on continuous tape strips while enabling efficient sampling.
