Solution Overview

Problem

Current treatments for burns and deep wounds, such as those using recombinant human growth factors, have limitations in promoting wound healing and can lead to inconsistent NF-kB expression, inflammation, and scar hyperplasia, with potential side effects.

Innovation Solution

A 15-amino acid polypeptide (SEQ ID No: 1) is used in topical formulations at ≥0.01% wt. to inhibit NF-kB activity, reducing inflammation and promoting skin regeneration, with formulations including liquid, ointment, and gel medicaments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If recombinant human growth factor gel (rh-EGF, rh-bFGF) is used to treat burns, then wound healing is promoted, but NF-kB expression becomes inconsistent and scar hyperplasia occurs

Engineering Contradiction:
Improvewound healing speedVSAvoidscar hyperplasia and inflammation
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The treatment approach is segmented into two distinct functions: first, inhibiting NF-kB activity to prevent inflammation and scar formation; second, promoting wound healing through epithelial cell proliferation. This segmentation allows each function to be optimized independently without the conflicting side effects of combined growth factor therapy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a peptidomimetic compound as an intermediary substance that specifically targets and inhibits NF-kB activity. This intermediary acts as a mediator between the harmful inflammatory response and the healing process, blocking the harmful signaling pathway while allowing beneficial healing mechanisms to proceed.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If growth factor gel is applied to deep wounds, then epithelial regeneration is promoted, but inflammation and inconsistent NF-kB expression occur

Engineering Contradiction:
Improveepithelial regeneration consistencyVSAvoidinflammation and NF-kB expression variability
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful role of NF-kB (which causes inflammation and inconsistent healing) into a beneficial approach by specifically inhibiting it. By targeting NF-kB inhibition, the treatment harnesses the knowledge of NF-kB's harmful effects and transforms it into a therapeutic mechanism that prevents inflammation while promoting consistent epithelial regeneration.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent changes the key parameter from promoting growth factor activity to inhibiting NF-kB activity. This parameter change fundamentally shifts the therapeutic mechanism from one that causes inconsistent NF-kB expression to one that consistently suppresses harmful NF-kB signaling while maintaining reliable wound healing outcomes.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If conventional burn treatments are used, then wound repair is achieved, but toxic side effects occur

Engineering Contradiction:
Improvewound repair efficiencyVSAvoidtoxic side effects
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent employs a peptidomimetic compound that acts as a temporary, localized treatment agent. This compound provides its therapeutic effect during the critical wound healing phase and then degrades, avoiding long-term toxic accumulation. The short-lived nature of the active compound ensures high efficacy during treatment while minimizing persistent side effects.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
