Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional biological material measurement devices are used, then the device structure is simple, but the device cannot selectively analyze specific materials contained in biological material samples
Solution Approach 1:
The measurement device is divided into multiple independent strips stacked together, where each strip contains a flow channel and a reaction unit with specific reaction-inducing material layers. This segmentation allows each strip to target specific materials (e.g., glucose, cholesterol, hemoglobin) while maintaining overall device simplicity through modular stacking.
Solution Approach 2:
The multi-layer strip structure integrates multiple functions into a single device: optical measurement, electrochemical measurement, and quantitative analysis of various biological materials. The stack of strips with different reaction-inducing materials enables the device to universally detect multiple substances simultaneously without requiring separate devices for each analysis.
2Productivity
If conventional measurement devices are used, then the device is simple to operate, but the effectiveness and range of application are limited
Solution Approach 1:
The device processes multiple biological materials simultaneously through stacked strips, each designed for specific measurements. This segmentation increases productivity by enabling parallel measurement of glucose, cholesterol, hemoglobin, and other materials in a single operational cycle, rather than requiring sequential testing.
Solution Approach 2:
The reaction units are pre-loaded with specific reaction-inducing material layers that automatically react with target materials when biological samples are introduced. The optical and electrochemical measurement systems automatically detect and quantify the reactions, reducing the need for complex manual operations while maintaining high measurement effectiveness.
3Measurement precision
If a stack of multiple strips with reaction-inducing material layers is used, then selective and quantitative analysis of multiple components is enabled, but the device complexity increases
Solution Approach 1:
The quantitative analysis capability is achieved through segmented strips, where each strip contains specialized reaction-inducing material layers for detecting specific materials. The segmentation allows precise measurement of each component independently while maintaining overall device manageability through modular stacking.
Solution Approach 2:
The device transitions from single-layer to multi-layer strip stacking, adding a vertical dimension to the measurement system. This dimensional change enables simultaneous quantitative analysis of multiple biological materials by stacking strips with different reaction-inducing materials, increasing measurement precision without significantly complicating the operational interface.
