Solution Overview
Problem
Current thermal insulation bags are ineffective for long-term temperature maintenance and are not suitable for emergency situations, as they require frequent removal and refrigeration to maintain temperature, making them inconvenient for quick cooling.
Innovation Solution
A thermal insulation backpack with adapter assemblies, including a fixing frame, sealing screen, and reset assembly, that allows for external cooling apparatus integration, enabling quick cooling without removing contents, using a sealing strip and return spring mechanism to control airflow and maintain insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If foods are placed in thermal insulation bags for temperature maintenance, then thermal insulation effect is achieved, but temperature of foods will elevate slowly over time and cannot be cooled quickly
Solution Approach 1:
The backpack is segmented into multiple functional modules: thermal insulation accommodation cavity, adapter assembly with sealing screen, and connection components. This modular design allows the cooling apparatus to be integrated without compromising the thermal insulation structure, enabling quick cooling while maintaining insulation effectiveness.
Solution Approach 2:
The adapter assembly acts as an intermediary mechanism between the thermal insulation cavity and the cooling apparatus. The sealing screen and sealing strip control the connection and disconnection between the cavity and external cooling, allowing quick temperature reduction while preserving the thermal insulation function when not in use.
2Temperature
If foods are removed from thermal insulation bags for refrigeration, then cooling effect is achieved, but operation becomes inconvenient and not suitable for emergencies
Solution Approach 1:
The invention merges the thermal insulation function with the cooling function into a single integrated backpack system. The adapter assembly enables the thermal insulation cavity to directly connect with external cooling apparatus, allowing foods to be cooled in place without removal, thus maintaining operational convenience while achieving effective cooling.
Solution Approach 2:
The sealing screen is designed to be movable, transitioning between blocking and opening positions. This dynamic mechanism allows users to quickly connect or disconnect the cooling apparatus without complex operations, making the system adaptable to emergency situations while maintaining ease of use.
3Speed
If adapter assembly is connected with external cooling apparatus, then quick cooling is achieved, but thermal insulation may be compromised
Solution Approach 1:
The sealing screen extracts the connection control function from the main thermal insulation structure. By placing the sealing mechanism at the connection interface, the thermal insulation cavity remains sealed and intact during normal operation, while allowing temporary connection to cooling apparatus when needed, thus preserving insulation integrity while enabling quick cooling.
Solution Approach 2:
The sealing strip acts as a flexible sealing element that can adapt to the connection interface. This flexible sealing mechanism ensures tight closure when the cooling apparatus is connected, preventing thermal leakage and maintaining insulation integrity even during the cooling process.
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 quick and convenient cooling of contents within the backpack, maintaining thermal insulation without removing items, making it suitable for emergency situations and easy to operate.
Implementation Method 1
a reset assembly (350), wherein the sealing screen (311) is connected with the reset assembly (350); when the adapter assembly (300) is connected with an external cooling apparatus, the sealing screen (311) moves to be close to an inside of the thermal insulation accommodation cavity (102), so that the connection recess (316) is communicated with the first through slot (312); when the adapter assembly (300) is not connected with the external cooling apparatus, the sealing screen (311) moves away from the inside of the thermal insulation accommodation cavity (102)
Implementation Method 2
a main body (100) and one or more adapter assemblies (300), wherein the main body (100) is internally provided with a thermal insulation accommodation cavity (102)

AI summary
A thermal insulation backpack enabling a rapid reduction in temperature without removing a product arranged therein and achieving a thermal insulation effect, and an operation method thereof. The thermal insulation backpack comprises a main body (10) and one or more adapter assembly (30). The main body (10) is provided with a thermal insulation accommodation cavity (102) therein, and provided with a connection hole (101) in communication with the thermal insulation accommodation cavity (102). The adapter assembly (30) is inserted into the connection hole (101), and comprises a fixing frame, a sealing screen (32), and a reset assembly. An outer periphery of the sealing screen (32) is provided with a sealing strip (321) protruding outward. A connection recess (316) and a first through slot (312) are provided in the fixing frame. The first through slot (312) is connected to the thermal insulation accommodation cavity (102). The sealing screen (32) is connected to the reset assembly. When the adapter assembly (30) is connected to an external cooling apparatus, the sealing screen (32) moves toward a direction of an interior of the thermal insulation accommodation cavity (102), such that the connection recess (316) is communicated with the first through slot (312). When the adapter assembly (30) is not connected to an external cooling apparatus, the sealing strip (321) presses against a lower end of the connection recess (316), such that the connection recess (316) is not communicated with the first through slot (312).
