Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional flat test strip is used with light emission over the entire area, then color determination is straightforward, but curved test strips cannot be accurately analyzed
Solution Approach 1:
The patent employs a flexible substrate unit that can dynamically adapt its shape to match the curvature of different test strips. The substrate unit is made of flexible material and is configured to be bent along with the test strip, allowing the light emitting and receiving units to maintain proper contact and alignment regardless of the test strip's curvature radius or shape.
Solution Approach 2:
The patent changes the physical state of the substrate unit from rigid to flexible to accommodate varying curvatures. By making the substrate unit flexible and capable of deformation, the system can adapt to different test strip configurations without requiring separate devices for each curvature type.
2Measurement precision
If separate devices are designed for different test strip curvatures, then measurement precision is maintained, but device complexity increases
Solution Approach 1:
The patent creates a universal urine analysis device that can handle multiple test strip types (flat, curved, different curvature radii) with a single device design. The flexible substrate unit serves as a universal adapter that can be configured to match any test strip geometry, eliminating the need for separate devices for different curvatures.
Solution Approach 2:
The flexible substrate unit dynamically adjusts its shape based on the test strip it is attached to, allowing one device structure to serve multiple functions across different test strip configurations without requiring multiple specialized devices.
3Stability of the object's composition
If the substrate unit is rigid, then structural stability is maintained, but adaptability to different curvatures is lost
Solution Approach 1:
The substrate unit is constructed from flexible material that can bend and deform to match the curvature of different test strips. This flexible substrate allows the light emitting and receiving units to maintain stable contact with the curved test strip surface while accommodating various curvature radii.
Solution Approach 2:
The substrate unit transitions from a rigid static structure to a flexible dynamic structure that can adapt its shape in real-time based on the test strip configuration, maintaining both structural integrity and adaptability.
