Mocha Pot Anti-Deflection Base Locking for Sealing Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The base of existing mocha pots is prone to deflection relative to the upper pot due to threaded connections, leading to potential leakage of coffee.
Innovation Solution
An anti-deflection mocha pot design featuring a convex ring with a press disc and base plate, sealed by an elastic sealing ring and multiple sealing locking members, preventing deflection and ensuring a high sealing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a threaded connection structure is used to connect the base and pot body, then the base can be detachably assembled, but the threaded connection may loosen during use causing deflection and leakage
Solution Approach 1:
The base is divided into an upper base portion and a lower base portion that can be separately assembled to the pot body, allowing detachable assembly while maintaining sealing through distributed sealing structures
Solution Approach 2:
The sealing ring is pre-installed on the pot body before assembly, and the pressing disc is designed with pressing portions that automatically apply sealing force when the base portions are assembled, ensuring sealing is established before any potential loosening occurs
2Device complexity
If the threaded pipe is arranged at the center of the base, then assembly is simplified, but the base becomes prone to deflection relative to the upper pot
Solution Approach 1:
The base is segmented into upper and lower portions that can be assembled separately, with the threaded connection points distributed at different locations rather than concentrated at the center, reducing the tendency for rotational deflection
Solution Approach 2:
The pressing disc combines multiple functions: it presses the sealing ring against the pot body, connects the upper and lower base portions, and provides structural support to prevent deflection, merging fastening and stabilization functions into a single component
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 effectively prevents deflection of the base relative to the pot body, maintaining a sealed state and preventing coffee leakage.
Implementation Method 1
The sealing structure is an elastic sealing ring connected to the inner ring wall of the convex ring in an interference clamping manner
Implementation Method 2
Both a lower end surface of the press disc and an upper end surface of the base plate are in elastic abutting fit with the extending ring edges

AI summary
The present disclosure relates to the technical field of mocha pot and discloses an anti-deflection mocha pot, which includes an upper pot. The upper pot includes a pot body and a base. The pot body is through from top to bottom, and the bottom horizontally extends inwards with a convex ring. The base includes a base plate on a lower end surface of the convex ring, a press disc on an upper end surface of the convex ring and an anti-deflection locking mechanism locking the press disc and the base plate. The anti-deflection locking mechanism includes at least two sealing locking members circumferentially arranged at equal intervals around a center of the base plate. A good sealing effect is achieved on the pot body and base of the upper pot of the mocha pot, and the base is prevented from being deflected relative to the pot body.
