Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing bags with zippers often fail to maintain a reliable seal due to particles or deformation between zipper components, leading to leakage and spoilage of contents.
Innovation Solution
A sealing system featuring an elastomeric protruding component with a slit and a covering assembly that engages with the component along two different directions to ensure a secure seal, utilizing interlocking portions and a sealing component to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a zipper is used for sealing, then the sealing effect can be provided to prevent leakage, but particles or deformation between zipper components cause improper mating and reduce sealing reliability
Solution Approach 1:
The patent removes the traditional zipper structure from the sealing system and replaces it with a novel sealing mechanism consisting of a sealing component with elastic deformation capability. This extraction eliminates the harmful effects of particles and deformation that plague zipper-based systems, as the new design uses a continuous elastic sealing surface that can adapt to minor irregularities without requiring precise interlocking components.
Solution Approach 2:
The patent employs parameter changes by utilizing the elastic properties of the sealing component. The sealing component is designed to undergo elastic deformation when pressed against the container opening, changing its physical state from rigid to flexible. This allows the sealing surface to conform to the container opening and maintain reliable sealing even in the presence of particles or surface irregularities.
2Ease of manufacture
If a zipper structure is used, then sealing function is achieved, but the structure is prone to deformation and particle interference reducing sealing effectiveness
Solution Approach 1:
The patent implements a flexible sealing component that acts as an elastic shell or film structure. This flexible sealing element can be pressed against the container opening to form a reliable seal, and it can be easily detached and reattached for repeated use. The flexible nature of this component makes it resistant to deformation and less susceptible to particle interference compared to rigid zipper structures.
3Reliability
If traditional sealing mechanisms are used, then basic sealing is provided, but sealing reliability is reduced due to improper mating of components
Solution Approach 1:
The patent segments the sealing system into two main parts: a container with an opening and a separate sealing component. The sealing component itself is segmented into a body and a sealing surface. This segmentation allows the sealing component to be manufactured independently with optimized properties for reliable sealing, while simplifying the overall structure by eliminating the complex interlocking mechanisms of traditional zippers.

Function Achieved in This Case
The system effectively prevents contents from entering or exiting the bag, enhancing the reliability of the sealing mechanism and maintaining freshness.
Implementation Method 1
The covering assembly squeezes the elastomeric protruding component along the protruding direction and a lateral direction different from the protruding direction to seal the slit

AI summary
A sealing bag includes a bag body and a sealing system. The sealing system includes an elastomeric protruding component and a covering assembly. The elastomeric protruding component is disposed on the bag body and protruding from the bag body along a protruding direction. A slit penetrates through the elastomeric protruding component along the protruding direction and is communicated with an inner space of the bag body. The covering assembly is for detachably engaging with the elastomeric protruding component. The covering assembly squeezes the elastomeric protruding component along the protruding direction and a lateral direction different from the protruding direction to seal the slit when the covering assembly engages with the elastomeric protruding component. Such mechanism can ensure nothing goes in or comes out when the slit is sealed. Therefore, the present invention has enhanced reliability.
