Solution Overview
Problem
Existing beverage preparation machines with extraction devices for single dose portions have complex constructions and high dimensions, lacking a simple and reliable mechanism for translating and rotating parts to efficiently collect and extract edible substances.
Innovation Solution
An extraction device comprising a box-like first part for translation movement, a lid-like second part for rotation movement, and a framework-like third part, with engagement paths and elastic means to facilitate a draw-like movement, enabling efficient collection and retention of single dose portions with reduced complexity and size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a swivelling mechanism with curved guiding pieces is used to transmit movement between parts, then the device can achieve rotation and translation movements, but the construction complexity increases
Solution Approach 1:
The extraction device is divided into three distinct parts: a box-like first part for translation movement, a lid-like second part for rotation movement, and a framework-like third part. This segmentation allows each part to have a specific function with simpler structure, avoiding the need for complex swivelling mechanisms while achieving the required movements.
Solution Approach 2:
Instead of using curved guiding pieces to transmit rotational movement, the patent inverts the approach by providing translation means with oblique engagement paths that naturally convert translation into rotation. The engagement paths are disposed in opposing side faces and develop in oblique manner relative to the translation direction, causing the second part to rotate as the first part translates.
2Adaptability or versatility
If multiple guiding mechanisms are provided for translation and rotation movements, then the extraction device can perform complex movements, but the device dimensions increase
Solution Approach 1:
The patent merges the translation and rotation movements into a single integrated mechanism. The translation means provide engagement paths that simultaneously achieve both translation of the first part and rotation of the second part, eliminating the need for separate guiding mechanisms and reducing overall device volume.
Solution Approach 2:
The engagement paths are disposed in opposing side faces of the first part and develop in oblique manner relative to the translation direction. This three-dimensional arrangement of engagement paths allows the mechanism to achieve complex movements (translation + rotation) within a compact space by utilizing spatial dimensions efficiently.
