Solution Overview

Problem

Current methods for reducing Beta-Amyloid levels, such as those in Alzheimer's disease, rely on semi-permeable membranes that are laborious to maintain and may not effectively target specific Beta-Amyloid peptides, often requiring intricate evaluation of membrane characteristics and risking escape of toxins back into the body.

Innovation Solution

A composition comprising a capturing and binding agent, specifically the KLVFF peptide or its variants, is introduced into the dialysate for extracorporeal treatment, binding to Beta-Amyloids and preventing their escape, using a standard dialysis machine to reduce Beta-Amyloid levels without relying on membrane performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If semi-permeable membranes are used for Beta-Amyloid reduction, then Beta-Amyloid levels can be reduced, but the device complexity and maintenance burden increase significantly

Engineering Contradiction:
ImproveBeta-Amyloid reduction effectivenessVSAvoidmembrane evaluation and maintenance complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts the Beta-Amyloid binding function from the complex semi-permeable membrane system and concentrates it into a specific peptide sequence (KLVFF) that can be incorporated into the dialysate. This separation allows the membrane to perform only its basic filtration function while the peptide handles the specific Beta-Amyloid capture, significantly reducing device complexity and maintenance requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The KLVFF peptide acts as an intermediary substance in the dialysate that mediates the interaction between the blood and the dialysis system for Beta-Amyloid removal. Instead of relying on the membrane's physical properties alone, the peptide provides a chemical binding mechanism that is easier to control and maintain.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If semi-permeable membranes are used for Beta-Amyloid filtration, then Beta-Amyloid levels can be reduced, but there is a risk that toxins may escape back into the body

Engineering Contradiction:
ImproveBeta-Amyloid removal effectivenessVSAvoidtoxin escape risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The KLVFF peptide in the dialysate performs preliminary binding action on Beta-Amyloids before they can potentially escape back into the body. By having the binding agent present in the dialysate from the start, the system ensures that any Beta-Amyloids that pass through the membrane are immediately captured, preventing their return to the bloodstream.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The peptide serves as a protective intermediary that binds to Beta-Amyloids on the dialysate side of the membrane, creating an additional safety barrier that prevents toxin escape even if the membrane has imperfections or allows passage of certain molecules.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If standard dialysis machines are modified to incorporate Beta-Amyloid binding agents, then treatment effectiveness improves, but manufacturing cost increases

Engineering Contradiction:
ImproveBeta-Amyloid treatment effectivenessVSAvoidmanufacturing complexity and cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention makes the dialysate multi-functional by incorporating the KLVFF peptide binding agent into the standard dialysis solution. This allows the same dialysis machine to perform both standard dialysis functions and Beta-Amyloid specific removal without requiring specialized equipment modifications, thereby maintaining ease of manufacture while improving treatment effectiveness.

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

Solution Approach 2:

Instead of modifying the expensive and complex dialysis machine hardware, the invention copies the Beta-Amyloid binding function into the consumable dialysate solution. This approach transfers the functional enhancement to a replaceable component that can be manufactured more simply and replaced between treatments.

Inventive Principle:
Principle #26Copying
