Airtight thermal insulation package
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior airtight thermal insulation packages have poor sealing effects and short service life due to inward bulged covers that are prone to water exposure, compromising the zipper's integrity.
Innovation Solution
An airtight thermal insulation package with a physical sucker structure at the convex edge of the opening, featuring a sucker rubber ribbon, guide groove, and snap-fit mechanisms, along with a waterproof zipper or bonding tape, to enhance sealing and prevent water vapor corrosion, while a placing tray with handles improves stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the package cover is designed to be bulged inward to cover the package periphery, then the package structure is compact, but the sealing effect of the package opening is poor and the zipper is easily wetted by water
Solution Approach 1:
The patent inverts the conventional cover design by making the cover edge convex rather than concave. The convex edge structure with sucker rubber ribbon positioned on the outer side prevents water from reaching the zipper while maintaining compact packaging volume, directly resolving the contradiction between compactness and sealing reliability
2Reliability
If the convex edge structure with sucker rubber ribbon is used, then the sealing effect is improved and waterproof performance is enhanced, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the convex edge structure: it serves as both the sealing surface and the waterproof barrier, while the sucker rubber ribbon combines adsorption function with sealing. This integration achieves improved reliability without proportionally increasing device complexity
3Stability of the object's composition
If the placing tray is provided with guide groove and elastic piece, then the placing tray stability is improved, but the device complexity increases
Solution Approach 1:
The guide groove and elastic piece create a self-guiding, self-latching mechanism for the placing tray. The elastic piece automatically provides resetting force and the guide groove ensures proper alignment without external intervention, achieving stability while minimizing the need for additional control mechanisms
