Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional airtight containers require additional coupling devices to discharge extra air, leading to inefficiencies in sealing and unsealing processes.
Innovation Solution
The design incorporates two airtight members with exhaust and releasing parts, allowing air to escape or enter through specifically positioned inlets and air gaps, enabling the cover to be sealed or unsealed by adjusting air pressure without additional coupling devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional airtight container uses a cover with sealing member to seal the container, then the container achieves airtight sealing, but additional coupling devices are required to discharge extra air inside the container
Solution Approach 1:
The patent combines the air discharge function with the sealing member by integrating exhaust channels and releasing channels directly into the sealing member structure. The sealing member simultaneously performs sealing and air discharge functions, eliminating the need for separate coupling devices. The exhaust part with first exhaust channel and second exhaust channel, along with the releasing part with releasing channel, are all integrated within the sealing member body.
Solution Approach 2:
The sealing member is designed to perform multiple functions: sealing the container opening, discharging excess air through exhaust channels, and allowing manual release of the seal through the releasing channel. This multi-functional design eliminates the need for additional specialized coupling devices for air discharge, simplifying the overall structure while maintaining airtight sealing capability.
2Ease of operation
If additional coupling devices are used to discharge extra air, then air can be discharged from the container, but the sealing and unsealing processes become less efficient
Solution Approach 1:
The patent merges the air discharge function with the sealing member by integrating exhaust channels and releasing channels directly into the sealing member structure. The sealing member simultaneously performs sealing and air discharge functions, eliminating the need for separate coupling devices. The exhaust part with first exhaust channel and second exhaust channel, along with the releasing part with releasing channel, are all integrated within the sealing member body.
Solution Approach 2:
The sealing member is pre-configured with exhaust channels and releasing channels that are ready to function immediately upon assembly. The air discharge pathways are established in advance through the integrated channels, eliminating the need for additional coupling devices during operation. This preliminary integration of air discharge functionality into the sealing member structure streamlines both sealing and unsealing processes.
3Device complexity
If the cover structure cannot discharge extra air inside the container, then the structure is simpler, but additional coupling devices are needed to achieve air discharge

AI summary
An airtight container includes a cover, a container and two airtight members. The cover is assembled with the container. The cover has an exhaust part and a releasing part defined therein. The two airtight members are mounted in the exhaust part and the releasing part of the cover respectively. Each airtight member having an inlet and an air gap defined at two ends thereof respectively. The air gap communicates with the inlet. The inlet of one airtight member opened toward an inside of the container and the air gap opened toward an outside of the container, the inlet of another airtight member opened toward the outside of the container and the air gap opened toward the inside of the container. Therefore, the container could be sealed or unsealed by pressing the cover to the container or detaching the cover from the container.
