Solution Overview

Problem

Current methods for preventing or reducing contamination of food and animal feed by Clostridium, particularly Clostridium perfringens, are inadequate and often compromise food quality, and there is a need for safe and effective antimicrobials.

Innovation Solution

A method involving the use of plant-expressed endolysins, such as ZP173 and derivatives, to prevent or reduce Clostridium contamination by contacting food with a composition containing these endolysins, which are produced using plant-based expression systems and can be used in semi-purified form.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional sterilization methods (autoclaving, chemical sterilants) are used on medical devices, then sterilization is achieved, but heat-sensitive or moisture-sensitive components are damaged

Engineering Contradiction:
Improvesterilization effectivenessVSAvoidcomponent integrity
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent replaces traditional thermal and chemical sterilization methods with a plasma-based sterilization system. The plasma generator creates a plasma field that penetrates packaging materials and sterilizes medical devices without requiring high heat or moisture, thus preserving heat-sensitive and moisture-sensitive components while achieving effective sterilization.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If packaging is opened in a controlled environment room, then contamination is reduced, but the process is time-consuming and complex

Engineering Contradiction:
Improvecontamination levelVSAvoidprocess complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies sterilization to the packaging container and medical device before sealing, creating a sterile environment within the packaging. This preliminary sterilization action eliminates the need for complex controlled environment rooms and lengthy assembly procedures, as the sterile barrier is already established before the package is sealed and transported.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a plasma-treated packaging material as an intermediary sterile barrier between the external environment and the medical device. This packaging material acts as a mediator that maintains sterility without requiring complex controlled environments, simplifying the overall process while effectively preventing contamination.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If medical devices are sterilized before packaging, then sterility is ensured, but heat-sensitive components are damaged

Engineering Contradiction:
Improvesterility assuranceVSAvoidthermal damage to components
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The patent replaces thermal sterilization methods with plasma sterilization. The plasma generator produces reactive species and UV radiation that achieve sterilization through chemical and photonic mechanisms rather than thermal heating, thereby ensuring sterility assurance while avoiding thermal damage to heat-sensitive electronic components and materials.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
