Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional disease diagnosis tools are used, then diagnosis can be performed, but they require external assistance and cannot be performed independently
Solution Approach 1:
The diagnosis tool is designed to enable self-diagnosis without requiring external assistance. The device allows users to independently apply reagents, load samples, and interpret results through clearly marked display areas and control features, eliminating the need for operator intervention while maintaining operational simplicity.
Solution Approach 2:
The device is divided into distinct functional modules including separate reagent application areas, sample loading zones, and result display regions. This segmentation allows each component to perform its specific function independently, making the overall complex device manageable and operable by users without specialized training.
2Adaptability or versatility
If conventional disease diagnosis tools are used, then single disease diagnosis can be performed, but they cannot diagnose multiple diseases simultaneously
Solution Approach 1:
The diagnosis tool is designed with multiple test zones on a single device that can detect different diseases simultaneously. Each zone is configured to detect specific biomarkers for different conditions, allowing one device to perform multiple diagnostic functions without requiring separate tools for each disease.
Solution Approach 2:
The device utilizes a two-dimensional array of test zones on the base plate, allowing multiple disease tests to be conducted in parallel across different spatial locations. This dimensional arrangement enables simultaneous multi-disease detection without increasing the device's footprint or operational complexity.
3Reliability
If conventional disease diagnosis tools are used, then diagnosis can be performed, but there is no way to verify whether self-diagnosis has been appropriately made
Solution Approach 1:
The device incorporates control zones and reference markers that provide visual feedback to confirm proper operation. These elements allow users to verify that the test has been conducted correctly and that results are valid, creating a feedback mechanism that ensures diagnostic reliability without adding complex verification systems.
Solution Approach 2:
The device uses color-changing indicators and marked display areas to show test results and validation status. Different colors indicate positive/negative results and proper/improper test execution, providing intuitive visual confirmation that helps users verify their self-diagnosis was performed appropriately.
4Productivity
If hydrophilic materials are used for base plate and pattern display panels, then water spreads sufficiently for rapid diagnosis, but manufacturing cost increases
Solution Approach 1:
The device employs hydrophilic materials with specific surface energy characteristics that promote water spreading. By optimizing the hydrophilicity parameter of the base plate and display panel materials, the device achieves rapid fluid distribution for fast diagnosis while selecting materials that balance performance with manufacturing cost considerations.
