Innovation Solution
A temperature control device with a wall section that can be attached and detached from the solution container, featuring a thermostat-controlled medium, flexible design, and overpressure adaptation, ensuring effective heat transfer while being sterilizable and easy to attach/detach, using materials like flexible plastic and thermally conductive coatings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a temperature control device is integrated into the solution container (double-coated design), then temperature control effectiveness is improved, but cleaning complexity and contamination risk increase
Solution Approach 1:
The temperature control device is segmented from the solution container into separate components: a removable temperature control jacket and a solution container. This segmentation allows the jacket to be easily removed for cleaning while the container remains separate, reducing cleaning complexity and contamination risk while maintaining temperature control effectiveness through the jacket's thermal contact with the container.
Solution Approach 2:
The temperature control medium and control mechanism are extracted from the integrated double-coated design and placed in a separate removable jacket. This extraction simplifies the solution container structure, making it easier to clean and sterilize, while the external jacket provides the temperature control function without compromising the container's integrity.
2Power
If thermally conductive grease is used between wall section and solution container, then heat transfer efficiency is improved, but removal and cleaning difficulty increase
Solution Approach 1:
A release liner or barrier layer is introduced as an intermediary between the thermally conductive grease and the solution container surface. This intermediary allows the grease to maintain optimal thermal contact for heat transfer efficiency while preventing permanent adhesion, enabling easy removal and cleaning of the temperature control jacket without residue buildup.
3Ease of operation
If the temperature control device is designed as removable and attachable, then ease of attachment and removal is improved, but contamination risk increases
Solution Approach 1:
The temperature control jacket is designed as a disposable component that can be easily attached and removed. After use, the entire jacket including any potential contamination is discarded, eliminating the need for complex cleaning and sterilization processes while maintaining ease of attachment and removal. This single-use approach prevents cross-contamination between different solution containers.
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 enables efficient temperature control with easy attachment and removal, prevents contamination, and allows for multiple uses in sterile environments, reducing production complexity and costs, while ensuring effective heat transfer and sterility.
Implementation Method 1
The temperature of the temperature-controlled medium is transferred to the medium located in the solution container via the first wall area
Implementation Method 2
In order to improve the temperature transition between the at least one wall section and the solution container, thermally conductive grease can be provided between the wall section and the solution container
Implementation Method 3
the at least one wall section is flexible... the inner diameter of the temperature control device changes, which finally adapts to the circumference of the pharmaceutical solution container
