Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealed containers face issues with the sealing ring being difficult to clean, requiring significant effort to open, and often resulting in inadequate sealing due to its simple structure.
Innovation Solution
A sealing ring design featuring a connecting portion, base portion, and abutting portion with a tapered structure and sealing lip, allowing for easy insertion and removal, which generates elastic forces for airtight sealing with reduced effort, and includes features like a compression space and nip portions for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealing ring is disposed in the engaging groove of the cover, then the sealing function is achieved, but the sealing ring becomes difficult to remove for cleaning
Solution Approach 1:
The sealing ring is divided into multiple functional segments: a removable sealing member that can be detached from the container body, and a stationary engaging groove in the cover. This segmentation allows the sealing member to be removed for cleaning while the cover remains in place, resolving the contradiction between maintaining sealing function and enabling cleanability.
Solution Approach 2:
The sealing member is extracted as a separate, removable component from the traditional integrated sealing structure. It can be taken out from the container body through the opening, allowing easy access for cleaning without removing the entire cover or container assembly.
2Reliability
If connecting portions and engaging portions are used to secure the sealing ring, then the sealing structure is stable, but great effort is required to open the container
Solution Approach 1:
The sealing member incorporates elastic deformation capabilities, allowing it to dynamically adapt between a compressed state during sealing and an expanded state during opening. The elastic material enables the sealing member to be inserted with minimal force while automatically maintaining sealing pressure, reducing the effort needed to open the container.
Solution Approach 2:
The sealing member's physical parameters (shape, volume, pressure) change during operation. When inserted, it deforms elastically to create sealing pressure; when removed, it returns to its original state. This parameter change allows the sealing function to be achieved without permanent structural modifications that would require great effort to reverse.
3Ease of manufacture
If the sealing ring has a simple structure, then it is easy to manufacture, but the sealing effect is insufficient
Solution Approach 1:
The sealing member incorporates localized functional features at specific positions: an abutting portion with a tapered structure at one location to engage the container bottom, and a sealing lip at another location to contact the insertion member. This local quality approach provides enhanced sealing effect without requiring complex overall structure, maintaining ease of manufacture.
Solution Approach 2:
The sealing member has an asymmetric structure with different features at different locations: a tapered abutting portion for engagement and a sealing lip for sealing. This asymmetric design optimizes the sealing effect at each location while keeping the overall structure relatively simple and easy to manufacture.
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 sealing ring is easier to clean and use, providing improved sealing efficacy with reduced effort required for opening and maintaining an airtight seal through elastic forces and vacuum creation.
Implementation Method 1
the insertion member exerts an outward pressing force F1 on the abutting portion to cause outward deformation of the abutting portion, which then produces a pushing force F2 toward the base portion
Implementation Method 2
The base portion generates an internal stress which is transmitted through the connecting portion and makes the sealing lip exert a pressure stress F3 on the abutting portion, thus forming an elastic force making the abutting surface of the abutting portion and the sealing surface of the sealing lip press against the insertion member in an airtight manner

AI summary
A sealing ring is an elastic annular member with an engaging groove for insertion of an insertion member. The engaging groove includes a sealing surface and an opposite abutting surface which is inclined from the bottom of the engaging groove toward the open end of the engaging groove, so that the open end of the engaging groove is narrower than the bottom of the engaging groove. When the insertion member is inserted in the engaging groove, the abutting surface and the sealing surface will transmit pressure to make the abutting surface of the abutting portion and the sealing surface of the sealing lip of the sealing ring are pressed against two sides of the inserted insertion member. Therefore, the sealing performance of the sealing ring is improved.
