Airtight Thermal Insulation Package with Large Zipper Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional thermal insulation packages have small openings, making them inconvenient for accessing food, prone to spills, and difficult to clean, and they do not promote good eating hygiene due to the placement of food and tableware inside the package.
Innovation Solution
An airtight thermal insulation package with a large opening, featuring a base, tableware box, thermal insulation package body, zipper enclosure, iron wire frame, and strap, where the zipper enclosure with an embedded iron wire frame unfolds to create a large opening, and the tableware box provides independent storage spaces for food and tableware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a small opening is used in the thermal insulation package, then the package structure is simple and airtight, but it is inconvenient for accessing food containers and causes soup to leak
Solution Approach 1:
The zipper enclosure is designed to be dynamically adjustable between a closed state for airtight sealing and an open state for easy access to food containers. The iron wire frame provides structural support that enables the zipper to maintain its shape when opened, creating a large opening while remaining integrated with the package body.
Solution Approach 2:
The opening mechanism is segmented into a zipper enclosure that can be independently opened and closed, separate from the main package body. This allows the opening function to be optimized for accessibility while the rest of the package maintains its simple airtight structure.
2Ease of operation
If food container is placed inside the package body, then the package is compact, but it is inconvenient to access and causes bad eating sanitary habits
Solution Approach 1:
The package is segmented into distinct functional zones: an outer pocket for food containers and a separate tableware box for utensils. This segmentation allows users to access food and tableware independently without compromising the airtight seal of the main package body, promoting better eating hygiene.
Solution Approach 2:
The outer pocket serves as an intermediary space between the user and the food containers, allowing easy access to food without opening the main airtight package. This intermediate access point maintains the integrity of the sealed package while providing convenient access to contents.
3Ease of manufacture
If a small opening is used in the thermal insulation package, then the package structure is simple, but it is difficult to clean due to soup leakage inside the package body
Solution Approach 1:
The outer pocket is extracted as a separate accessible compartment from the main package body. This allows users to easily remove and clean items in the outer pocket without having to open the main sealed package or disassemble the entire structure, maintaining both simplicity and ease of cleaning.
4Ease of operation
If the package is designed for portability with folding capability, then it is light and fashionable, but the opening is small and inconvenient for accessing food
Solution Approach 1:
The zipper enclosure provides a dynamic opening mechanism that can be easily deployed to create a large opening when needed, without requiring additional structural components that would increase weight. The iron wire frame within the zipper enclosure provides sufficient structural support for this dynamic opening function.
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 design allows for easy access and cleaning, maintains airtight sealing, and promotes better eating hygiene by providing a spacious and sanitary arrangement for food and tableware, enhancing the usability and convenience of thermal insulation packages.
Implementation Method 1
the zipper enclosure is internally embedded with the iron wire frame; the iron wire frame comprises a left iron wire frame and a right iron wire frame; When the zipper of the zipper enclosure with the iron wire frame is opened, the left iron wire frame and the right iron wire frame in the package opening can be oppositely unfolded
Implementation Method 2
