Capsule Infusion Chamber Guide Mechanism for Gravity Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infusion devices for preparing beverages from single-serving capsules are complex and costly due to the need for intricate mechanisms to position and retain capsules within the infusion chamber, which complicates both the insertion and unloading processes.
Innovation Solution
A simplified infusion device design featuring two movable portions of the infusion chamber with guide channels and extractor members that allow for easy capsule insertion and unloading, utilizing a lever mechanism for manual operation and elastic elements for efficient opening and closing, enabling capsules to be loaded and unloaded by gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex mechanisms are used to position and retain capsules within the infusion chamber, then capsule positioning reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The capsule insertion mechanism utilizes the user's own hand movements to automatically position and insert the capsule. When the user opens the lid, the capsule is naturally guided into the infusion chamber by the guide channels formed by the first and second portions, eliminating the need for complex automated positioning mechanisms.
Solution Approach 2:
The infusion chamber is divided into two separate portions (first portion and second portion) that can move independently relative to each other. This segmentation allows each portion to have simplified guide channels that work together to position the capsule, rather than requiring a single complex retention mechanism.
2Stability of the object's composition
If intricate mechanisms are used for capsule insertion and unloading, then capsule retention stability is improved, but ease of operation deteriorates
Solution Approach 1:
The guide channels formed by the first and second portions automatically guide the capsule into the correct position during the natural opening motion of the lid. The user's own operation of opening the lid performs the capsule insertion function, making the process intuitive and easy.
Solution Approach 2:
The guide channels are designed to be dynamic rather than static - they are formed by the relative movement between the first and second portions of the infusion chamber. As the lid opens, the portions move apart and create the guiding path that naturally positions the capsule.
3Manufacturing precision
If complex retention mechanisms are used, then capsule positioning precision is improved, but device manufacturing cost increases
Solution Approach 1:
The positioning function is distributed between two separate portions (first portion and second portion) rather than requiring a single precision mechanism. Each portion has simpler guide channels that are easier to manufacture, but together they achieve the required positioning precision through their relative movement.
Solution Approach 2:
The guide channels are designed to create a natural gravitational path for the capsule. The channels are positioned and shaped so that the capsule naturally settles into the correct position under gravity and the natural motion of opening the lid, eliminating the need for complex precision retention mechanisms.
4Reliability
If intricate mechanisms are used for capsule handling, then capsule extraction reliability is improved, but ease of repair deteriorates
Solution Approach 1:
The extraction function is distributed between the first and second portions through their guide channels, rather than requiring a single complex extraction mechanism. This segmentation makes each component simpler and more accessible for maintenance and repair.
Solution Approach 2:
The natural opening and closing motion of the lid automatically performs the capsule extraction function through the guide channels. The mechanism extracts the capsule as a byproduct of the normal opening operation, requiring no separate complex extraction mechanism that would need maintenance.

AI summary
A device including a first portion of an infusion chamber and a second portion of an infusion chamber, movable with respect to each other according to an opening and closing direction; a first duct to feed an infusion fluid into said infusion chamber; a second duct for delivery of the food product from the infusion chamber; a pair of guide channels to insert a capsule into a space between the first portion of the infusion chamber and the second portion of the infusion chamber. The guide channels are each produced on a respective movable element; and the movable elements are positioned substantially opposite each other and can be opened to release the capsule into the infusion chamber.
