Solution Overview

Problem

Current methods for stabilizing bio-therapeutics, such as proteins, require refrigeration to prevent thermal degradation, which is costly and impractical for resource-constrained regions, especially in Sub-Saharan Africa where high temperatures render life-saving drugs ineffective.

Innovation Solution

A dendron-based formulation that includes a dendron of specific structure, monoclonal antibodies, a buffer solution, and a salt, which stabilizes bio-therapeutics at temperatures up to 55°C, preventing degradation and maintaining therapeutic efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If refrigeration is used to stabilize bio-therapeutics, then thermal degradation is prevented, but storage cost and operational complexity increase

Engineering Contradiction:
Improvestability of bio-therapeuticsVSAvoidrefrigeration requirement
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent changes the chemical parameters of the formulation by incorporating specific stabilizing agents (sugars, amino acids, peptides, proteins, or their combinations) that enable the bio-therapeutics to maintain stability at higher temperatures (up to 55°C) without requiring refrigeration. This parameter change in the formulation composition directly resolves the contradiction by eliminating the need for complex refrigeration systems while preserving therapeutic stability.

Principle #35Parameter changes

2Stability of the object's composition

If refrigeration is used to stabilize bio-therapeutics, then thermal degradation is prevented, but implementation difficulty in resource-constrained regions increases

Engineering Contradiction:
Improvestability of bio-therapeuticsVSAvoidease of storage and distribution
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

By modifying the formulation to include thermoprotective agents that raise the stable storage temperature range, the patent makes the bio-therapeutics suitable for storage in hot and humid conditions without refrigeration. This enables distribution to resource-constrained regions where refrigeration infrastructure is unavailable, directly improving ease of operation and accessibility.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If high temperature storage is attempted without stabilization, then refrigeration cost is reduced, but therapeutic efficacy is lost due to degradation

Engineering Contradiction:
Improvestorage costVSAvoidtherapeutic efficacy
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent incorporates specific stabilizing agents (sugars, amino acids, peptides, proteins) in defined concentrations that chemically protect the bio-therapeutics from thermal degradation. These agents maintain the structural integrity and biological activity of the therapeutics even at elevated temperatures (up to 55°C), thereby enabling cost-effective storage without refrigeration while preserving therapeutic efficacy.

Inventive Principle:
Principle #35Parameter changes

4Stability of the object's composition

If existing stabilization methods are used, then some protection is achieved, but stability at temperatures above 25°C is insufficient

Engineering Contradiction:
Improvestability at refrigerated temperaturesVSAvoidmaximum stable storage temperature
Core Design Contradiction:
Stability of the object's compositionVSTemperature

Solution Approach 1:

The patent employs composite stabilization strategies by combining multiple types of stabilizing agents (sugars, amino acids, peptides, and/or proteins) in specific formulations. This composite approach creates synergistic effects that significantly elevate the maximum stable storage temperature from typical refrigerated conditions (2-8°C) to ambient and even elevated temperatures (up to 55°C), resolving the temperature limitation of existing methods.
