Storage Cover Elastic Rim Airtight Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage covers for storage cases are inconvenient to use due to complex opening and closing operations and suffer from deteriorating airtightness over time, especially when made of flexible materials like rubber or synthetic resin, which also lack effective sterilization capabilities.
Innovation Solution
A storage cover design featuring a plate-shaped cover unit with an elastic flexible rim and reinforcing units, including airtight protrusions and ventilation units, that allows for easy opening and closing by pulling back upper and lower parts, maintaining airtight coupling force and preventing deformation, even when made of flexible materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking units are foldably provided on the sides of the storage cover to couple with the storage case, then airtight coupling is achieved, but the opening and closing operations become very complicated and inconvenient to use
Solution Approach 1:
The invention extracts the locking units from the sides of the storage cover and relocates them to the front end. This allows the locking units to be operated independently by a single hand without requiring complex side-folding operations, thereby simplifying the opening and closing operations while maintaining airtight coupling capability
Solution Approach 2:
Instead of having the locking units fold from the sides toward the center, the invention inverts the design by placing locking units at the front end that can be pulled or pushed in a linear direction. This inversion transforms the complex side-folding operation into a simple front-to-back linear motion
2Reliability
If the storage cover is made of flexible rubber or synthetic resin to maintain airtightness, then flexibility and sealing are improved, but the storage cover is easily transformed and twisted and vulnerable to heat
Solution Approach 1:
The invention applies composite materials by combining flexible rubber or synthetic resin with glass fiber reinforcement. The glass fiber mesh is embedded within the flexible material to provide structural support and prevent deformation, while the flexible material maintains airtightness and flexibility
Solution Approach 2:
The invention changes the physical parameters of the storage cover by incorporating glass fiber reinforcement, which increases the tensile strength and dimensional stability of the flexible material without significantly compromising its flexibility or airtight sealing capability
3Adaptability or versatility
If the storage cover is made thin to be flexible, then flexibility is improved, but the storage cover is easily transformed and twisted
Solution Approach 1:
The invention uses composite materials combining thin flexible rubber or synthetic resin with glass fiber mesh reinforcement. This allows the storage cover to remain thin and flexible while the glass fiber provides structural integrity to prevent transformation and twisting
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 simple one-touch opening and closing operations while maintaining airtightness and preventing deformation of the storage cover, ensuring the freshness of stored goods and allowing for air and heat discharge, thus improving user convenience and storage case performance.
Implementation Method 1
a flexible rim 140 extended along the edge of the cover unit 110 in the direction of the thickness of the cover unit 110, made of an elastic material to be elastically extended, and pulled back toward the upper part of the cover unit 110 when the opening 210 is opened and pulled back toward the lower part of the cover unit 110 when the opening 210 is closed

AI summary
A storage cover for a storage case is provided. The storage cover for the storage case for opening and closing an opening formed on one side of a storage case to take in and out stored goods includes a plate-shaped cover unit for covering the upper part of the opening and a flexible rim extended along the edge of the cover unit in the direction of the thickness of the cover unit, made of an elastic material to be elastically extended, and pulled back toward the upper part of the cover unit when the opening is opened and pulled back toward the lower part of the cover unit when the opening is closed to surround the external circumference of the opening. Therefore, opening and closing operations are simply performed so that the storage cover can be conveniently used and that airtight coupling force can be maintained in spite of the repeated opening and closing operations.
