Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods (AAS, XRF, ICP-AES, UV-VIS, IR spectroscopy) are used to determine mineral particle content, then measurement precision is improved, but measurement time, device complexity, and operational difficulty increase significantly
Solution Approach 1:
The patent replaces complex analytical instrumentation (spectrometers, fluoroscopy equipment) with a simple optical comparison method using a grayscale card. Instead of using advanced physical measurement systems, the invention uses visual perception and simple photography to achieve mineral content determination, dramatically reducing measurement time and equipment complexity while maintaining sufficient precision for the application.
Solution Approach 2:
The invention creates a visual copy of the mineral content information through grayscale imaging. By photographing the test strip and comparing the grayscale values to a reference card, the system captures and analyzes the mineral content data in a simplified digital format, eliminating the need for complex spectral analysis while preserving the essential measurement information.
2Measurement precision
If conventional methods are used for mineral particle determination, then measurement precision is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent replaces complex analytical instrumentation (spectrometers, fluoroscopy equipment) with a simple optical comparison method using a grayscale card. Instead of using advanced physical measurement systems, the invention uses visual perception and simple photography to achieve mineral content determination, dramatically reducing measurement time and equipment complexity while maintaining sufficient precision for the application.
Solution Approach 2:
The invention uses a simple, inexpensive grayscale card as the measurement reference, replacing expensive, complex instrumentation. The test strip itself serves as a disposable measurement medium that combines the sample holder and measurement interface functions, eliminating the need for costly reusable analytical equipment.
3Measurement precision
If conventional methods are used for mineral particle determination, then measurement precision is improved, but ease of operation deteriorates due to requiring expert knowledge
Solution Approach 1:
The patent replaces complex analytical instrumentation (spectrometers, fluoroscopy equipment) with a simple optical comparison method using a grayscale card. Instead of using advanced physical measurement systems, the invention uses visual perception and simple photography to achieve mineral content determination, dramatically reducing measurement time and equipment complexity while maintaining sufficient precision for the application.
Solution Approach 2:
The test strip system is designed to be self-explanatory and self-evaluating. The grayscale patterns on the test strip directly correspond to mineral content levels, allowing users to interpret results without specialized training. The system performs its own measurement and presentation functions, eliminating the need for expert operation.
4Measurement precision
If conventional methods are used for mineral particle determination, then measurement precision is improved, but sample preparation complexity increases
Solution Approach 1:
The patent combines the sample application area and measurement interface into a single integrated test strip. The test strip simultaneously serves as the substrate for formulation application, the measurement platform, and the reference comparison card, eliminating the need for separate sample preparation steps and complex instrumentation setup.
Solution Approach 2:
The test strip acts as an intermediary medium that simplifies sample preparation. Instead of requiring direct analysis of the original formulation with complex instrumentation, the test strip provides a standardized interface that transforms the formulation into a visually evaluable format, greatly simplifying the preparation process.
