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 durability and heat resistance.
Innovation Solution
A storage cover design featuring a plate-shaped cover unit with a flexible rim made of elastic material, reinforced with protrusions and rings to maintain shape and airtightness, allowing easy opening and closing by pulling back upper and lower parts, and incorporating ventilation units for air management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking units are used to couple the storage case and storage cover, then airtightness is improved, but the opening and closing operations become very complicated
Solution Approach 1:
The patent removes the complex locking units from the storage cover design and replaces them with a simple flexible rim that elastically couples to the storage case. This extraction of the locking mechanism eliminates the complicated folding and coupling operations while maintaining airtightness through the elastic deformation of the rim material.
Solution Approach 2:
The patent changes the physical state of the rim from rigid (as in locking unit designs) to flexible and elastic. This parameter change allows the rim to deform elastically during coupling and maintaining constant pressure for airtightness, simplifying the operation to just placing the cover on the case without complex locking actions.
2Adaptability or versatility
If the storage cover is made of thin flexible rubber or synthetic resin, then flexibility is improved, but the cover becomes easily transformed and twisted
Solution Approach 1:
The patent employs composite material construction by combining a flexible base material (rubber or synthetic resin) with reinforcing units made of stiffer material. This composite structure provides both the flexibility needed for elastic coupling and the shape stability to prevent twisting and transformation during use.
Solution Approach 2:
The patent applies local quality enhancement by adding reinforcing units at specific locations on the storage cover where structural support is needed. These localized reinforcements prevent twisting and transformation in critical areas while maintaining overall flexibility of the cover for proper coupling with the storage case.
3Ease of operation
If the storage cover is made of flexible material, then ease of coupling is improved, but heat resistance deteriorates preventing sterilization
Solution Approach 1:
The patent modifies the material parameters by selecting heat-resistant flexible materials such as certain silicones or polyimides that can withstand high temperatures. This parameter change allows the cover to maintain its flexible, easy-to-couple properties while also resisting degradation at sterilization temperatures, enabling both ease of operation and heat resistance.

Function Achieved in This Case
Enables simple and efficient opening and closing operations while maintaining airtight coupling force, preventing deformation and twisting of the cover, and allowing for air and heat discharge to maintain food freshness.
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.
