Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation is used for preparative separation and analysis, then the user can control each step, but the time and labor required increase significantly

Engineering Contradiction:
Improveease of operationVSAvoidtime and labor
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The chromatograph apparatus performs preparative separation and analysis operations automatically without requiring continuous user intervention. The system executes preparative separation based on set conditions, automatically identifies target components, and performs detailed analysis without manual data retrieval or condition re-setting, thereby reducing time and labor while maintaining operational control

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The user sets preparative separation and analysis conditions in advance before starting the operation. The system stores these conditions and automatically retrieves and applies them during the preparative separation and subsequent analysis processes, eliminating the need for manual condition re-setting and reducing operational time

Inventive Principle:
Principle #10Preliminary action

2Reliability

If manual checking of separation results is required, then the user can verify specific information, but the process becomes more complex and time-consuming

Engineering Contradiction:
Improveverification of separation resultsVSAvoidprocess complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically retrieves identification information of the preparative separation container from the preparative separation results and provides this feedback to the analysis execution unit. This automatic information feedback eliminates the need for manual checking and verification by the user, reducing process complexity while maintaining reliability through automated data accuracy

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system merges the preparative separation result retrieval function with the analysis condition execution function. The identification information from preparative separation is automatically integrated and used to set analysis conditions without requiring separate manual verification steps, thereby simplifying the overall process while ensuring data reliability

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If separate setting of preparative separation and analysis conditions is required, then each condition can be optimized, but the number of operation steps increases

Engineering Contradiction:
Improveoptimization of separation and analysis conditionsVSAvoidnumber of operation steps
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The chromatograph apparatus integrates multiple functions into a unified system that handles both preparative separation and detailed analysis. The system uses a single set of pre-configured conditions that govern both operations, allowing the same apparatus to perform multiple functions (preparative separation, target component identification, and detailed analysis) without requiring separate condition setting procedures for each step, thereby optimizing both separation and analysis while reducing operation steps

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A sample container (172) holding a sample and a preparative separation container (173) for containing a target component obtained from the sample by preparative separation can be arranged in a preparative separation device (17). A preparative-separation-and-analysis conditions setter (42) allows users to set a preparative separation condition for the target component and an analysis condition for the target component after the preparative separation. A preparative separation executer (43) collects a sample from the sample container, separates the target component contained in the sample, and puts the separated target component into the preparative separation container according to the preparative separation condition after the preparative separation condition and the analysis condition are set. An analysis executer (44) collects the target component from the preparative separation container and performs an analysis of the target component according to the analysis condition, after the preparative separation of the target component.
