Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dialysis is performed to separate a target substance, then separation can be achieved, but a large device, large amount of solvent, and long treatment time are required

Engineering Contradiction:
Improveseparation effectivenessVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical dialysis system with an electrophoresis system that uses electric fields to separate substances. Instead of relying on osmotic pressure and diffusion through membranes, the invention uses charged particles moving under electric field influence, enabling separation in a compact device with reduced solvent volume and shorter processing time

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

Solution Approach 2:

The invention changes the separation mechanism from passive diffusion-based dialysis to active electric field-driven electrophoresis. By applying voltage and utilizing the charge properties of target substances, the system achieves faster separation with smaller device dimensions and less solvent requirement

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If glycerol is added to concentrate a target substance by dialysis, then concentration can be achieved, but the viscosity of the solution increases and affects analysis or measurement

Engineering Contradiction:
Improveconcentration of target substanceVSAvoidsolution viscosity
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical concentration methods (glycerol addition) with electrophoretic concentration. Target substances are concentrated by applying electric field to move charged particles into a smaller volume, achieving concentration without adding viscous chemicals that would interfere with subsequent analysis

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

Solution Approach 2:

The invention uses an electric field as an intermediary to achieve concentration without chemical additives. The electric field drives charged target substances to migrate and accumulate in a defined region, providing a clean concentration method that maintains solution properties suitable for analysis

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If two-dimensional electrophoresis is performed to separate a target substance, then separation precision is improved, but the process requires electrophoresis to be performed twice and requires the area of a two-dimensional gel

Engineering Contradiction:
Improveseparation precisionVSAvoidtreatment time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent employs a single electrophoresis system that can perform multiple separation functions by adjusting operating parameters such as voltage, pH, and gel composition. This universal approach achieves comprehensive separation without requiring sequential two-dimensional electrophoresis, reducing treatment time while maintaining separation precision

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