Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple LEDs are arranged to provide different wavelengths, then the sample analysis device can perform multi-wavelength testing, but the device complexity and size increase due to the need for multiple LEDs and shaping components
Solution Approach 1:
The patent combines multiple LEDs with different wavelengths into a single integrated LED component. This multi-color LED integrates multiple light-emitting elements that can emit different wavelengths simultaneously or sequentially, eliminating the need for separate LEDs and their corresponding shaping components for each wavelength, thus reducing device complexity while maintaining multi-wavelength testing capability
Solution Approach 2:
The integrated multi-color LED serves multiple functions by providing different wavelengths for different testing methods (coagulation assay, immunoturbidimetric assay, and chromogenic substrate assay). This single component replaces what would traditionally require multiple specialized LEDs, achieving versatility in wavelength provision while simplifying the overall device structure
2Manufacturing precision
If multiple LEDs with shaping components are used for optical fiber coupling, then each wavelength can be precisely coupled, but the device size increases and compact design becomes difficult
Solution Approach 1:
The patent merges multiple LED sources and their associated shaping components into a single integrated multi-color LED unit. This consolidation maintains the precision needed for optical fiber coupling by incorporating the light-shaping functionality within the integrated component itself, thereby reducing the overall device volume while preserving coupling precision
Solution Approach 2:
The patent implements a nested structure where multiple light-emitting elements are integrated within a single LED component housing. The shaping components are nested within or integrated with the LED structure, allowing precise optical coupling while minimizing the external footprint and enabling a more compact device design
