Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RT-PCR test is used for pathogen detection, then measurement precision is improved, but loss of time increases due to excessive processing duration
Solution Approach 1:
The test system is segmented into modular components: a reusable processing unit and disposable test cartridges. This segmentation allows pre-preparation of reagents and materials in the cartridge, enabling rapid testing without compromising accuracy. The cartridge contains pre-measured reagents and integrated sample collection elements, eliminating time-consuming preparation steps while maintaining RT-PCR level detection precision.
Solution Approach 2:
All necessary reagents, buffers, and control elements are prepared and integrated into the test cartridge before use. The cartridge is pre-assembled with magnetic beads, lysis buffers, and PCR reagents in optimal configurations. This preliminary action eliminates on-site preparation time and ensures consistent, accurate results while dramatically reducing the time from sample collection to result.
2Measurement precision
If invasive swabbing is used for sample collection, then measurement precision is improved, but ease of operation deteriorates due to discomfort
Solution Approach 1:
A soft, flexible sampling tip acts as an intermediary between the user's nostril and the sample collection mechanism. This intermediary element is designed to be comfortable and non-invasive, allowing users to self-administer the test without the discomfort of traditional rigid swabs. The sampling tip effectively transfers nasal secretions to the collection cartridge while maintaining sample integrity for accurate detection.
Solution Approach 2:
The test system is designed for self-administration by the user without requiring medical professionals. The sampling process is simplified to allow users to comfortably collect their own samples by following visual or digital instructions. The cartridge automatically processes the sample, eliminating the need for skilled operators while maintaining diagnostic accuracy through standardized sample collection and processing protocols.
3Measurement precision
If complex lab equipment is used for pathogen detection, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The complex mechanical and manual laboratory equipment is replaced with a simplified cartridge-based system that uses magnetic separation and integrated fluidics. Magnetic beads automatically capture and concentrate viral particles from the sample, and pre-loaded reagents perform lysis and amplification through simple user actions. This substitution maintains RT-PCR level detection accuracy while eliminating the need for complex centrifuges, vortex mixers, and temperature-controlled incubators.
Solution Approach 2:
The detection system changes key operational parameters from complex laboratory conditions to simplified home-use parameters. The cartridge is designed to work at room temperature or with minimal heating, eliminating the need for complex thermal cycler equipment. Chemical reactions are optimized to proceed with simple mixing or brief incubation periods, maintaining detection sensitivity while dramatically reducing equipment requirements and operational complexity.
4Ease of manufacture
If traditional distribution methods are used for test kits, then ease of manufacture is improved, but productivity decreases due to difficulty in mass distribution
Solution Approach 1:
The test cartridge is designed as a universal platform that can detect multiple pathogens using the same basic architecture. By incorporating interchangeable reagent cartridges or multiplex detection capabilities, a single distribution system can serve multiple public health needs. This universality allows mass distribution through existing postal and delivery infrastructures while maintaining ease of manufacture through standardized production processes.
Solution Approach 2:
The system uses disposable, single-use cartridges that are inexpensive to manufacture and distribute. Each cartridge is pre-packaged with all necessary reagents and components, eliminating the need for complex sterilization and quality control infrastructure at distribution points. The low cost per unit enables mass distribution through conventional mail services and retail outlets, dramatically increasing accessibility and productivity while maintaining manufacturing simplicity through standardized, high-volume production techniques.
