Protective Bodies for Sterilization Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sterilization devices for containers, particularly those using radiation and charge carriers, are sensitive to contamination and aggressive cleaning agents, leading to frequent breakdowns during maintenance and cleaning operations due to physical shocks.
Innovation Solution
An apparatus with movable sterilization units and protective bodies that surround the rod-like bodies, allowing for safe insertion and protection during cleaning and maintenance operations, using a carrier system with independent movement mechanisms to ensure all rod-like bodies are partially or fully enclosed within protective bodies during these processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If beam fingers are made thin-walled to enable high electron accelerations, then electron acceleration capability is improved, but mechanical strength and resistance to shocks deteriorates
Solution Approach 1:
The beam finger is inserted into a protective body that surrounds it, creating a nested structure where the delicate beam finger is protected by the more robust protective body during cleaning and maintenance operations
Solution Approach 2:
The protective body acts as an intermediary between the beam finger and external shocks or cleaning agents, absorbing mechanical stresses and preventing direct contact between aggressive cleaning media and the sensitive beam finger
2Reliability
If beam fingers are made delicate to achieve required electron accelerations, then sterilisation effectiveness is improved, but sensitivity to contamination and cleaning agents increases
Solution Approach 1:
The beam finger is nested within a protective body that shields it from contamination and cleaning agents during maintenance operations
Solution Approach 2:
The protective body is positioned around the beam finger before cleaning operations begin, providing preemptive protection against contamination and aggressive cleaning agents
3Reliability
If protective bodies are introduced to protect rod-like bodies, then reliability of sterilisation apparatus is improved, but device complexity increases
Solution Approach 1:
The protective device is divided into multiple protective bodies, each associated with a specific sterilisation unit and rod-like body, allowing independent protection and maintenance of individual components
Solution Approach 2:
The protective bodies are designed to be movable relative to the rod-like bodies, allowing them to be positioned for protection during cleaning operations and repositioned during sterilisation operations, providing adaptability without permanent complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces the risk of damage to the sensitive components, enhancing the reliability and longevity of the sterilization apparatus by providing comprehensive protection during cleaning and maintenance, thereby minimizing breakdowns and ensuring continuous operation.
Implementation Method 1
each sterilisation unit has a source of radiation or respectively a radiation emitting device and/or a charge carrier source
Implementation Method 2
irradiate this container from the inside with charge carriers and in particular with electrons

AI summary
A method for operating an apparatus for sterilizing containers where the containers are each held and are transported along a predefined path by means of a movable carrier, and a plurality of sterilization units are arranged on the carrier, each having rod-like bodies that are introduced into the containers and apply charge carriers onto an internal wall of the containers. The charge carriers exit through an exit window of the rod-like bodies, as the charge carriers move in a longitudinal direction relative to the rod-like bodies.
