Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing button-type airtight containers face challenges with difficult assembly, reliability issues, and dirt accumulation at the seal ring section, leading to poor airtightness and cleaning difficulties.
Innovation Solution
A button-type airtight container lid design featuring a rotary toothed member with helicoid spline teeth, a lever spring mechanism, and a dish seal ring fixed by double-shot injection molding, facilitating easy assembly and cleaning, with a ratchet mechanism ensuring high airtightness and stable performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hinge rod mechanism is used to connect the lever and connection post, then the airtight container achieves high airtightness through lever spring mechanism, but the assembly becomes complex and difficult to assemble in poor visibility conditions
Solution Approach 1:
The patent removes the complex hinge rod mechanism from the design and replaces it with a simpler button-driven lever spring mechanism. The lever is directly connected to the connection post without requiring a separate hinge rod, eliminating the assembly difficulty while maintaining the airtight sealing function through the seal ring compression.
Solution Approach 2:
The patent divides the lid into an inner lid and outer lid with the seal ring positioned between them. This segmentation allows the seal ring to be independently compressed by the lever mechanism to achieve airtightness, while the button mechanism separately controls the lever movement, simplifying the overall assembly process.
2Reliability
If the seal ring is embedded in the groove of the inner lid, then the airtight container achieves high airtightness, but the groove creates hard-to-clean corners that accumulate dirt and breed bacteria
Solution Approach 1:
The patent extracts the seal ring from the traditional groove embedding structure. Instead of embedding the seal ring in a groove of the inner lid, the seal ring is positioned between the inner lid and outer lid, allowing it to be compressed by the lever mechanism. This eliminates the hard-to-clean groove corners while maintaining effective sealing.
Solution Approach 2:
Instead of embedding the seal ring into the inner lid groove (traditional approach), the patent inverts the structure by positioning the seal ring on the outer lid and compressing it inward between the lids. This inversion eliminates the problematic groove structure while achieving the same airtight sealing function.
3Reliability
If four buckles are used to buckle up the container, then the airtight container achieves high airtightness, but the closing operation becomes inconvenient and complex
Solution Approach 1:
The patent merges the four separate buckle operations into a single button-pressing action. The button mechanism simultaneously activates the lever spring mechanism, which compresses the seal ring between the inner lid and outer lid, achieving airtight sealing in one simple operation rather than requiring four separate buckling actions.
Solution Approach 2:
The single button mechanism serves multiple functions: it activates the lever mechanism, compresses the seal ring, and achieves airtight sealing all at once. This multi-functional design replaces the four separate buckles, maintaining high airtightness while dramatically improving closing convenience.
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 design provides easy assembly, high reliability, and stable operational performance, with a cleanable and dirt-resistant seal ring section, enhancing the airtightness and maintenance of the container.
Implementation Method 1
a seal ring undergoes compressive deformation under the action of the inner lid and outer lid
Implementation Method 2
the rotary toothed member includes a sleeve and N spline teeth, the spline teeth being provided at the top and bottom with a helicoid
Implementation Method 3
the lower lid includes a 2N-tooth end ratchet, whose ratchet tooth is adapted to the lower helicoid of the spline tooth
