Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging containers face challenges in controlling liquid discharge amounts and internal sealing, particularly for products like sponges and brushes, where external sealing is not feasible.
Innovation Solution
A rotary sealed packaging container design featuring an outer lid and hollow inner core, where the inner core moves axially and the outer lid rotates circumferentially, utilizing a thread matching system to control the liquid outlet's opening and closing, allowing for adjustable liquid discharge through a sealing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external sealing is used for packaging containers, then the sealing structure is simple, but it cannot be applied to products like sponges and brushes and cannot control liquid discharge amount
Solution Approach 1:
The patent implements internal sealing by nesting the sealing component inside the container body. The sealing ball is positioned within the container's internal cavity, allowing the sealing mechanism to be integrated within the product structure rather than applied externally. This enables sealing for products like sponges and brushes that cannot accommodate external sealing structures.
Solution Approach 2:
The patent employs a dynamic sealing mechanism where the sealing ball can move vertically within the container body. By rotating the outer lid, the user controls the vertical position of the sealing ball, allowing it to dynamically open or close the liquid outlet. This dynamic adjustment enables controlled liquid discharge while maintaining sealing capability.
2Ease of operation
If external sealing is used, then the structure is simple, but the liquid discharge amount cannot be controlled
Solution Approach 1:
The patent employs a dynamic sealing mechanism where the sealing ball can move vertically within the container body. By rotating the outer lid, the user controls the vertical position of the sealing ball, allowing it to dynamically open or close the liquid outlet. This dynamic adjustment enables controlled liquid discharge while maintaining sealing capability.
Solution Approach 2:
The patent introduces a sealing ball as an intermediary component between the liquid outlet and the external environment. This spherical sealing element acts as a mediator that can be precisely positioned to either block or allow liquid flow, providing fine-grained control over discharge amount without requiring complex valve mechanisms.
3Ease of operation
If internal sealing is implemented with rotary outer lid, then liquid discharge can be controlled, but the structure becomes more complex
Solution Approach 1:
The patent integrates multiple functions into the outer lid structure. The outer lid serves both as a closure component and as a control mechanism for the sealing ball. By combining the lid function with the sealing control function, the patent reduces the need for separate control mechanisms, thereby managing structural complexity while achieving liquid discharge control.
Solution Approach 2:
The patent merges the sealing mechanism with the container body structure. The sealing ball is integrated within the container's internal cavity, and the thread part is formed as an integral component of the container body. This merging of components reduces the number of separate parts and simplifies the overall structure while maintaining the internal sealing functionality.
