Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound healing treatments face challenges with antibiotic-resistant bacteria, cytotoxicity issues, and instability of peroxyacid-based disinfectants, which hinder effective antimicrobial action and wound healing.
Innovation Solution
A composition comprising α-keto peracids and non-alpha keto peroxyacids, which are synergistically combined to form a stable, broad-spectrum antimicrobial agent for wound treatment, reducing corrosivity and cellular toxicity, and providing both short-term and long-term antimicrobial efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If peroxyacid-based disinfectants are used for wound treatment, then broad-spectrum antimicrobial efficacy is achieved, but instability and rapid decomposition occur
Solution Approach 1:
The patent adjusts the pH of the composition to a specific range (pH 2-8) to optimize the stability-activity balance. By controlling this critical parameter, the peracid remains stable during storage yet becomes sufficiently active to kill microorganisms when applied to wounds.
Solution Approach 2:
The patent combines peracids with other compatible substances to create a composite composition that enhances overall stability. This composite approach allows the peracid to maintain its antimicrobial properties while being stabilized by the presence of other components in the formulation.
2Reliability
If conventional antibiotics are used for wound treatment, then bacterial infections are controlled, but antibiotic-resistant bacteria develop
Solution Approach 1:
The patent employs peracids as strong oxidizing agents that kill microorganisms through oxidation of essential cellular components. This mechanism of action is fundamentally different from conventional antibiotics, preventing the development of resistance since bacteria cannot evolve protective mechanisms against non-specific oxidative damage.
Solution Approach 2:
The patent converts the potentially harmful instability and reactivity of peracids into a beneficial broad-spectrum antimicrobial effect. The same properties that cause rapid decomposition also enable the peracid to effectively kill even resistant bacteria and spores, turning a disadvantage into a therapeutic advantage.
3Reliability
If high concentrations of antimicrobial agents are used, then killing efficacy against spores and bacteria is improved, but cellular toxicity increases
Solution Approach 1:
The patent optimizes the concentration and pH parameters to achieve maximum antimicrobial efficacy at minimal toxic concentrations. By carefully controlling these parameters, the composition kills spores and bacteria effectively while maintaining safety for wound tissues.
Solution Approach 2:
The patent uses peracids as intermediaries that generate reactive oxygen species in situ at the wound site. This allows the antimicrobial action to occur locally where needed, while the parent peracid molecules can be controlled to minimize systemic toxicity and unwanted effects on healthy tissues.
