Frozen Liquid Wrapping With Isolated Temperature Sensor Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring the temperature of biological liquids during freezing and unfreezing processes are unreliable due to direct contact with reading devices, potential contamination, and unstable positioning, leading to inaccurate data and high production costs.
Innovation Solution
A wrapping design with containment walls and a through opening for a temperature reading device, isolated from the liquid chamber, allowing safe and precise temperature monitoring without direct contact, facilitating easy device placement and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the reading device is positioned inside a blind recess isolated from the liquid containment chamber, then contamination risk is reduced, but the reading device can be accidentally removed or moved during bag movement and freezing, making data unreliable
Solution Approach 1:
The patent introduces an intermediary mechanism (retaining structure or engagement feature) between the reading device and the blind recess that prevents accidental removal or movement. This intermediary element allows the device to remain securely positioned while still being accessible for intentional removal, thus maintaining both contamination protection and data reliability.
2Ease of operation
If the reading device is placed in direct contact with the liquid containment chamber (e.g., through a duct), then temperature reading is easier, but liquid contamination and leaking problems occur
Solution Approach 1:
The patent extracts the reading device from direct contact with the liquid containment chamber by positioning it within a blind recess that is isolated from the liquid. This separation eliminates the contamination and leaking problems while maintaining the ability to read temperature through the wall of the containment chamber.
3Object-affected harmful factors
If a blind recess is used to isolate the reading device from the liquid chamber, then contamination is prevented, but the bag structure becomes more complicated and costly to manufacture
Solution Approach 1:
The patent implements the blind recess using flexible containment walls and thin film materials that can be sealed and formed during the standard bag manufacturing process. This approach creates the isolated recess structure without requiring complex rigid components, thereby preventing contamination while minimizing increases in structural complexity and manufacturing cost.

AI summary
The wrapping (1) for containing and preserving a liquid substance (S) intended to be frozen, comprises at least two containment walls (4, 7) associated the one with the other to define a chamber (2) for containing the liquid substance (S), at least a seat (3), isolated from the containment chamber (2), for housing a temperature reading device (T) for reading the temperature of the liquid substance (S), where the containment walls (4, 7) comprise at least two outer walls (4) which substantially define the outer overall dimensions of the wrapping itself and at least a supporting wall (7) which delimits the seat (3) and which is configured so as to define a through opening through the containment chamber (2).
