Solution Overview
Problem
Conventional blotting techniques suffer from resolution losses during membrane transfer, require labor-intensive procedures, and are prone to size and hydrophobicity biases, as well as poor reagent delivery, making them impractical for clinical use and inefficient in separating large molecules.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional blotting techniques use dense polymer matrices for separation, then separation resolution is improved, but reagent delivery becomes poor and analysis time increases
Solution Approach 1:
The patent applies dynamics by using a stimulus-responsive polymer matrix that can dynamically change its pore size in response to external stimuli (such as pH, temperature, or chemical agents). The matrix transitions from a dense state during separation to a swollen state during reagent delivery, allowing the system to optimize for both separation resolution and reagent accessibility at different stages of the analysis
Solution Approach 2:
The patent utilizes parameter changes by modifying the physical state of the polymer matrix through external stimuli. The matrix exhibits reversible transitions between collapsed (dense) and swollen (porous) states, allowing control over pore size and polymer chain conformation to achieve both high-resolution separation and efficient reagent delivery
2Productivity
If conventional blotting techniques use high density polymers for reagent delivery, then reagent delivery is improved, but separation performance deteriorates
Solution Approach 1:
The stimulus-responsive matrix dynamically adjusts its density and pore structure based on the operational phase. During reagent delivery, the matrix is in a swollen state with large pores that facilitate rapid reagent diffusion, while during separation, it transitions to a dense state for high-resolution biomolecule separation
Solution Approach 2:
The patent employs parameter changes by using external stimuli to control the degree of polymer chain expansion and collapse. This allows the matrix to switch between a dense configuration for separation and an expanded configuration for reagent delivery, optimizing both functions sequentially
3Manufacturing precision
If conventional blotting techniques are used, then biomolecule separation is achieved, but labor-intensive procedures and multi-step processes are required
Solution Approach 1:
The patent merges multiple functions into a single integrated matrix system. The stimulus-responsive polymer matrix simultaneously performs separation, provides reagent delivery pathways, and enables detection, eliminating the need for separate transfer membranes and multiple processing steps required in conventional blotting techniques
Solution Approach 2:
The patent applies universality by designing a multi-functional matrix that can perform separation, facilitate reagent delivery, and support detection activities within a single phase. This eliminates the need for sequential operations involving multiple membranes and complex procedural steps
