A beverage brewing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage brewing devices cannot eject used infusion material cleanly, simply, and effectively without requiring manual operation to open the brew chamber, leading to inefficient waste management and disposal of infusion packets.
Innovation Solution
A beverage brewing device with a cylindrical brew chamber and a plunger that has a flexible seal, where the openable base is closed by friction fit and can be opened by the plunger's action, allowing for the automatic ejection of used infusion material as a 'puck' into a waste receptacle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the brew chamber has a fixed closed base, then the brewing structure is simple and reliable, but the used infusion material cannot be ejected automatically
Solution Approach 1:
The base of the brew chamber is designed to transition from a static closed state during brewing to a dynamic open state during ejection. The base includes a hinge connection allowing it to rotate from covering the discharge end to an open position, enabling automatic ejection without manual intervention while maintaining structural simplicity.
Solution Approach 2:
The brew chamber is divided into separable components: the main body and the movable base. This segmentation allows the base to independently perform its dual function of sealing during brewing and opening for ejection, resolving the contradiction between automation and structural simplicity.
2Ease of operation
If manual operation is required to open the brew chamber, then the structure remains simple, but the operation becomes complex and inefficient
Solution Approach 1:
The plunger is designed to perform multiple functions: compressing the infusion material during brewing and automatically triggering the base to open for ejection. This self-service mechanism eliminates the need for separate manual operations to open the chamber, improving ease of operation while keeping the base mechanism simple with only a hinge connection.
3Productivity
If the base is always open, then the ejection of used infusion material is easy, but the brewing process becomes inefficient due to loss of containment
Solution Approach 1:
The base dynamically transitions between closed and open states based on the operational phase. During brewing, the base remains closed to maintain containment and efficiency. During ejection, the base automatically opens to facilitate easy discharge of used material, thus achieving both brewing efficiency and ease of ejection.
Solution Approach 2:
The base performs periodic actions: closed during the brewing phase to maintain containment, then opens during the ejection phase. This periodic switching between states ensures optimal brewing efficiency while enabling easy ejection when needed, without requiring the base to be permanently open.
