Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual purification and concentration steps are performed, then analysis results can be obtained, but analysis time increases and results vary depending on analyst skill level

Engineering Contradiction:
Improveanalysis result consistencyVSAvoidpre-treating time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical operations with an automated liquid handling system that uses robotic arms, automated pipettes, and computer-controlled mechanisms to perform extraction, purification, and concentration steps. This substitution eliminates human skill variability and significantly reduces processing time while maintaining consistent analysis results.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system incorporates self-contained cartridges with pre-packed sorbent materials that automatically perform purification functions when solvent is passed through them. The automated system also self-regulates flow rates, timing, and sequence of operations without human intervention, enabling consistent results independent of operator skill level.

Inventive Principle:
Principle #25Self-service

2Productivity

If manual purification and concentration steps are performed, then analysis can be completed, but the process becomes complex and time-consuming

Engineering Contradiction:
Improveanalysis efficiencyVSAvoidpre-treating process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the complex pre-treatment process into distinct modular stages: extraction, purification through separate cartridges, concentration, and preparation. Each stage is handled by specialized components (extraction vessels, purification cartridges, concentration devices) that can be automatically sequenced, reducing overall process complexity despite the multiple steps involved.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The automated liquid handling system serves multiple functions including precise liquid transfer, automated pipetting, cartridge handling, and sequence control. This multi-functional automation platform manages the entire pre-treatment workflow, simplifying the complexity of coordinating multiple manual operations while significantly improving productivity.

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