Sterilization Device Unlocking Class B Cycles via Software Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sterilization devices are limited to a single class of sterilization, necessitating costly replacements to upgrade to higher classes like Class B, which is not environmentally friendly and lacks flexibility for varying sterilization needs.
Innovation Solution
A sterilization device capable of operating in multiple classes (S, B, and optionally N) with locked and unlockable cycle programs, allowing conversion between classes using a code or key, incorporating steam pulsing and vacuum systems for air removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sterilizer is designed to provide only Class S sterilization, then the device complexity and cost are reduced, but the adaptability and versatility are limited
Solution Approach 1:
The sterilizer is designed with multiple sterilization cycle programs (Class N, Class S, and Class B) integrated into a single device, allowing it to perform multiple sterilization functions. The controller can execute different cycle programs based on user selection, enabling the device to adapt to various sterilization needs without requiring separate sterilizers for each class.
Solution Approach 2:
The sterilizer incorporates dynamic configuration through lockable and unlockable cycle programs. The controller can dynamically enable or disable specific sterilization classes (N, S, or B) based on activation codes or user permissions, allowing the device to adapt its functionality over time without physical modifications.
2Adaptability or versatility
If a sterilizer is upgraded from Class S to Class B by replacing the device, then the sterilization capability is improved, but the loss of substance and environmental waste increase
Solution Approach 1:
Instead of discarding the original Class S sterilizer when upgrading to Class B, the invention allows the existing device to be retained and reconfigured. The controller software is updated or reprogrammed to enable Class B sterilization cycles, and the device hardware is utilized as-is, thereby recovering the value of the original investment and avoiding electronic waste.
3Adaptability or versatility
If multiple sterilization cycle programs are made available, then the adaptability is improved, but the ease of operation may deteriorate due to complexity
Solution Approach 1:
The sterilization cycle programs are segmented into distinct classes (N, S, and B), each with clearly defined parameters and indications. The controller presents these as separate, identifiable options to the user, allowing them to select the appropriate class based on their specific needs without being overwhelmed by a single complex menu.
Solution Approach 2:
The invention uses inexpensive activation codes or software keys to control access to different sterilization classes. These codes can be easily distributed and activated without requiring complex hardware changes, allowing flexible enabling/disabling of programs while maintaining operational simplicity for the end user.
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
Enables flexible sterilization options, reduces waste by allowing existing devices to be upgraded, and provides cost-effective access to multiple sterilization classes without full replacement.
Implementation Method 1
Class S sterilizers use active air removal by for example steam pulsing
Implementation Method 2
steam pulsing... air removal from the sterilizer
Implementation Method 3
Class B sterilizers use active air removal by for example using a vacuum pump
Implementation Method 4
sterilization using a suitable sterilization medium, such as for example steam and heat
