Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If remeasurement is performed by preparing a diluted sample, then analytical accuracy is improved, but operator load increases and testing speed decreases
Solution Approach 1:
The system performs preliminary determination processing to assess whether remeasurement is necessary before actually performing the dilution and remeasurement steps. This allows the system to prepare diluted samples only when analytically necessary, reducing unnecessary operational steps and improving testing speed while maintaining accuracy requirements.
Solution Approach 2:
The automatic analyzing apparatus performs self-determination of whether remeasurement is needed through its determination processing circuitry, eliminating the need for operator judgment. The system automatically decides when dilution and remeasurement are necessary based on analytical criteria, reducing operator load and enabling faster automated decision-making.
2Measurement precision
If remeasurement is performed by preparing a diluted sample, then analytical accuracy is improved, but operator load increases
Solution Approach 1:
The automatic analyzing apparatus performs self-determination of whether remeasurement is needed through its determination processing circuitry, eliminating the need for operator judgment. The system automatically decides when dilution and remeasurement are necessary based on analytical criteria, reducing operator load and enabling faster automated decision-making.
Solution Approach 2:
The system replaces operator mechanical operations and judgment with automated determination processing circuitry. The automated system evaluates analytical data and decides whether remeasurement is necessary, substituting human cognitive and manual operations with automated electronic processing, thereby reducing operator load.
3Measurement precision
If the reaction is continued for extended measurement, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary determination processing to assess whether extended reaction time is necessary before committing to it. By evaluating analytical data in advance, the system can identify cases where extended measurement will improve precision and schedule these accordingly, optimizing the balance between time investment and precision gain.
Solution Approach 2:
The system dynamically adjusts the reaction time based on the specific analytical requirements of each sample. Rather than using a fixed extended reaction time for all samples, the determination processing circuitry evaluates each case and adjusts the measurement duration accordingly, improving precision when needed while minimizing time loss when not necessary.
