Control Cuvette Observation Pattern for Measurement Accuracy Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement systems face challenges in ensuring accurate detection of formed elements in liquid samples due to insufficient dispersion of control substances, the need for multiple types of control substances for varied elements, difficulty in obtaining control substances for rare elements, and limitations in long-term storage of liquid-derived control substances.
Innovation Solution
A control cuvette with an observation pattern representing the shape of formed elements applied to its observation surface, allowing for measurement accuracy control by simulating the image capture of these elements after precipitation on the cuvette's bottom surface, enabling adjustment and sensitivity confirmation of the measurement apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If control substance is used for accuracy control, then measurement accuracy can be controlled, but the formed element needs to be thoroughly dispersed in the liquid sample which is difficult to achieve
Solution Approach 1:
The patent applies the copying principle by creating a control cuvette that contains an observation pattern representing the shape of formed elements, rather than using actual control substances. This pattern is applied directly to the observation surface, eliminating the need for physical dispersion of control elements in liquid samples while still enabling accuracy control through image comparison.
2Adaptability or versatility
If control substances are provided for multiple types of formed elements, then accuracy control for various elements is achieved, but the number of control substances needed increases
Solution Approach 1:
The patent applies universality by designing a control cuvette with an observation surface that can display observation patterns for multiple types of formed elements. This single multi-functional control cuvette replaces the need for multiple separate control substances, allowing accuracy control for various element types without increasing the number of physical control substances required.
3Measurement precision
If control substance is obtained for rare formed elements, then accuracy control for rare elements is achieved, but it is difficult to obtain such control substances
Solution Approach 1:
The patent applies the copying principle by creating observation patterns that represent rare formed elements directly on the control cuvette's observation surface. This eliminates the need to physically obtain or prepare rare control substances, as the patterns can be created through imaging and replication processes, making accuracy control for rare elements readily achievable.
4Duration of action of stationary object
If liquid-derived control substance is stored long-term, then accuracy control is maintained, but the control substance may deteriorate
Solution Approach 1:
The patent applies the copying principle by replacing the physical control substance with an observation pattern applied to the control cuvette surface. This pattern is stable and does not deteriorate over time like biological control substances, enabling long-term storage while maintaining reliability for accuracy control purposes.

AI summary
A control cuvette used for measurement accuracy control in a measuring apparatus for observing a formed element contained in a liquid sample after precipitating the formed element to a bottom surface of a cuvette, wherein an observation pattern representing a shape of the formed element contained in the liquid sample is provided at an observation surface of the control cuvette corresponding to the bottom surface of the cuvette.
