Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a single layer of capture molecules is used for analyte capture, then the device structure is simple, but the sensitivity and signal-to-noise ratio are limited

Engineering Contradiction:
ImprovesensitivityVSAvoidstructure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent transitions from a two-dimensional single layer of capture molecules to a three-dimensional molecular net structure. This dimensional change increases the capture capacity and signal intensity while maintaining structural organization through the network architecture of interconnected capture molecules and linker molecules.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The molecular net is constructed as a composite structure comprising capture molecules of at least one type and linker molecules of a plurality of types covalently bonded to form a multi-layered three-dimensional matrix. This composite architecture enhances sensitivity and signal-to-noise ratio compared to simple single-layer structures.

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If capture molecules are densely packed on the surface, then the capture capacity increases, but non-specific binding increases

Engineering Contradiction:
Improvecapture capacityVSAvoidnon-specific binding
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The molecular net structure creates localized capture zones where capture molecules are positioned at specific nodes within the three-dimensional network. This local organization maintains high capture capacity while the distributed network architecture reduces non-specific binding by preventing uniform surface coverage that promotes non-specific interactions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The covalently-linked multi-layered three-dimensional matrix forms a porous network structure with interconnected voids and channels. This porous architecture increases capture capacity by providing multiple access pathways and binding sites while reducing non-specific binding through size exclusion and reduced surface contact area.

Inventive Principle:
Principle #31Porous materials

3Loss of time

If sample preparation is minimized for rapid detection, then the analysis time is reduced, but the complexity of handling unprocessed samples increases

Engineering Contradiction:
Improveanalysis timeVSAvoidsample handling complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The molecular net structure enables direct capture of analytes from unprocessed samples without requiring extensive sample preparation steps. The three-dimensional network with its multiple binding sites and porous structure performs self-service by automatically capturing target analytes while excluding interfering substances, eliminating the need for complex pretreatment protocols.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent changes the structural parameters of the capture surface from simple two-dimensional layers to complex three-dimensional molecular nets with controlled porosity and connectivity. This parameter change allows the system to handle unprocessed samples directly by providing steric exclusion of interferents while maintaining high affinity capture of target analytes.

Inventive Principle:
Principle #35Parameter changes
