Solution Overview

Problem

Current methods for treating diseases using systemic monoclonal antibodies are expensive and associated with severe side effects due to ill-defined fate and immune reactions, while existing devices for immobilized antibodies are cumbersome and costly to implement.

Innovation Solution

A method of producing a solid coated carrier by incubating a solid carrier with a solution containing couplers like diaminoalkanes or polyethyleneglycol, attaching antibodies, and embedding them in a matrix with substances like peptides and sugars to create a stable, sterile device for therapeutic and diagnostic applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If systemic monoclonal antibodies are administered to treat diseases, then therapeutic effects are achieved, but severe side effects and high costs occur due to immune reactions and ill-defined fate

Engineering Contradiction:
Improvetherapeutic safetyVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the therapeutic function of monoclonal antibodies from systemic circulation and relocates it to an immobilized state on a solid carrier surface. This separation allows the antibody to exert its therapeutic effect locally without being distributed systemically, thereby eliminating immune reactions and side effects associated with systemic administration while maintaining therapeutic efficacy

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a solid carrier as an intermediary between the antibody and the biological environment. The carrier surface serves as a mediator that holds the antibody in a controlled, immobilized state, enabling therapeutic action without direct systemic introduction of the antibody, thus avoiding harmful immune responses

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If devices with immobilized antibodies are used to avoid systemic side effects, then therapeutic safety improves, but device complexity and implementation burden increase

Engineering Contradiction:
Improvetherapeutic safetyVSAvoidimplementation burden
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent modifies the physical state of the antibody from soluble/systemic to immobilized/surface-bound by changing its spatial configuration and interaction parameters with the carrier surface. This parameter change enables the antibody to function therapeutically in a simplified device format without requiring complex systemic delivery mechanisms, reducing implementation burden while maintaining safety

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a localized therapeutic environment by immobilizing antibodies on a solid carrier surface with specific properties. The carrier surface provides a defined local environment that concentrates therapeutic activity at the site of need without requiring complex systemic distribution mechanisms, thereby simplifying device implementation while ensuring therapeutic safety

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If antibodies are immobilized on a solid carrier, then side effects are minimized, but manufacturing complexity increases due to multiple coating and treatment steps

Engineering Contradiction:
Improveside effectsVSAvoidmanufacturing simplicity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent applies preliminary coating steps to the solid carrier surface before antibody immobilization, including application of couplers and blocking agents. These preliminary actions prepare the surface in advance to ensure optimal antibody binding and prevent non-specific interactions, thereby minimizing side effects while establishing a standardized manufacturing protocol that can be replicated

Inventive Principle:
Principle #10Preliminary action

4Manufacturing precision

If multiple coating steps are applied to the solid carrier, then manufacturing precision improves, but production time and complexity increase

Engineering Contradiction:
Improvecoating uniformityVSAvoidproduction time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent employs periodic, sequential coating steps with defined intervals and conditions for each layer application. This periodic approach allows each coating layer to be applied, dried, and stabilized in sequence, ensuring manufacturing precision and uniformity while maintaining an efficient production rhythm that minimizes total production time

Inventive Principle:
Principle #19Periodic action
