Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional Pap smear methods are used, then diagnostic accuracy can be improved through detailed examination, but productivity decreases due to sequential processing of single samples

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidscreening throughput
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The invention divides the screening process into multiple independent wells on a single slide, allowing parallel processing of multiple samples while maintaining the diagnostic quality of individual examinations. Each well contains a separate patient sample and can be evaluated independently, thus increasing throughput without sacrificing diagnostic accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention combines multiple patient samples on a single glass slide in separate wells, enabling simultaneous processing and evaluation of multiple samples in one diagnostic workflow. This merging approach maintains the precision of individual sample examination while dramatically increasing productivity through parallel processing.

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If conventional single-sample processing is used, then diagnostic quality can be maintained through focused examination, but loss of time increases due to sequential evaluation of multiple samples

Engineering Contradiction:
Improvediagnostic qualityVSAvoidscreening time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

By segmenting multiple samples into separate wells on a single slide, the invention allows diagnosticians to examine multiple samples in parallel rather than sequentially. Each well maintains the focused examination quality of single-sample processing while reducing total screening time through simultaneous evaluation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention enables continuous evaluation of multiple samples on a single slide without the need to repeatedly prepare and handle separate slides for each sample. This continuity eliminates idle time between sample examinations while maintaining diagnostic quality through standardized well configurations.

Inventive Principle:
Principle #20Continuity of useful action

3Adaptability or versatility

If manual Pap smear processing is used, then flexibility can be maintained for various examination protocols, but productivity decreases due to labor-intensive sequential processing

Engineering Contradiction:
Improveexamination flexibilityVSAvoidprocessing throughput
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The segmented well design allows each well to be processed independently according to different protocols or staining methods, maintaining flexibility for various examination approaches. Simultaneously, the parallel arrangement of multiple wells on one slide enables higher throughput compared to sequential single-sample processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The multiwell slide design serves multiple functions: it can accommodate different sample types, support various staining protocols, and enable both manual and automated processing. This universality maintains examination flexibility while increasing productivity through efficient use of a single slide format for multiple samples.

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