Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If external modules are used for data collection and measurement functions in conventional AUC systems, then device complexity is reduced and ease of operation is improved, but measurement precision and data quality deteriorate

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent integrates the light source, sample chamber, and detector into a single unified rotor assembly, eliminating the need for separate external modules. This merging of previously separate components into one integrated unit directly improves measurement precision while the modular design maintains operational simplicity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated rotor serves multiple functions simultaneously: it contains the sample, provides the rotating centrifugal force, houses the light source, and incorporates the detector. This multi-functional design achieves high measurement precision without proportionally increasing overall system complexity.

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

2Productivity

Solution Approach 1:

By combining the light source, sample, and detector into a single rotating assembly, the system eliminates transmission delays and synchronization issues between separate modules. This enables real-time data acquisition during rotation, significantly improving productivity and data acquisition speed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated rotor allows continuous data collection throughout the centrifugation process without interruption for module repositioning or synchronization. The light source and detector remain continuously aligned with the sample during rotation, enabling uninterrupted measurement and improving overall productivity.

Inventive Principle:
