Capsule Perforation Geometry for Uniform Centrifugal Beverage Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation devices using centrifugation suffer from blocked flow due to membrane accumulation on perforating members, which hinders the homogeneous distribution of the beverage exiting the capsule.
Innovation Solution
The use of perforating members with cutting edges arranged essentially parallel to the central axis, featuring a displacement portion and pressure release means, prevents membrane accumulation and ensures efficient drainage by creating clean, evenly distributed outlet openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pyramidal or conically shaped perforating members with low angle of inclination are used, then the membrane can be perforated, but the membrane accumulates on the surface of the perforating member and blocks the beverage flow
Solution Approach 1:
The invention changes the geometric parameters of the perforating member by providing cutting edges arranged essentially parallel to the central axis (angle of inclination between 80-100 degrees), rather than using traditional low-angle conical shapes. This parameter change prevents membrane accumulation while maintaining effective perforation.
Solution Approach 2:
The invention introduces asymmetric features through the displacement portion that is offset from the central axis, creating an asymmetric overall shape that prevents membrane material from accumulating on the surface while maintaining effective cutting action.
2Manufacturing precision
If conventional perforating members are used, then perforation can be achieved, but homogeneous beverage distribution is prevented due to blockages
Solution Approach 1:
By changing the angle parameter of the cutting edge to be essentially parallel to the central axis (80-100 degrees), the invention ensures clean perforations without membrane accumulation, thereby ensuring reliable and uniform beverage distribution through all outlet openings.
Solution Approach 2:
The invention segments the perforating member into distinct functional portions: a cutting edge portion for creating perforations and a displacement portion for preventing blockages. This segmentation allows each portion to optimize its specific function without interfering with the other.
3Manufacturing precision
If membrane accumulation occurs on perforating members, then perforation function is maintained, but beverage extraction efficiency is reduced
Solution Approach 1:
The invention converts the potentially harmful membrane accumulation into a beneficial displacement action. The displacement portion is specifically designed to push membrane material away from the outlet, transforming what would be a blockage into a mechanism that enhances beverage flow and extraction efficiency.
