Reusable Brewing Filter with Integrated Scraper Ejection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reusable brewing filters for single-serve coffee machines lack an integrated cleaning mechanism, making it difficult and inefficient for users to remove spent coffee grounds, leading to a messy and time-consuming cleaning process.
Innovation Solution
The integration of a cleaning mechanism within the brewing filter, comprising a rotating scraper with vertical and horizontal cleaning members, allows for efficient ejection of spent coffee grounds by rotating the mechanism externally to scrape the interior surfaces and discharge the grounds into a disposal container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning methods are used to remove spent coffee grounds, then the brewing filter can be reused, but the cleaning process is time-consuming and messy
Solution Approach 1:
The brewing filter is equipped with an integrated cleaning mechanism that enables it to clean itself. The scraper arm with cleaning members can be rotated to scrape spent coffee grounds from the interior surfaces and deposit them into a collection container, eliminating the need for manual cleaning operations by the user.
Solution Approach 2:
A scraper arm acts as an intermediary mechanism between the spent coffee grounds and the collection container. The scraper arm with its cleaning members physically contacts and transports the spent grounds from the brewing chamber interior to the collection container, facilitating efficient removal without direct manual intervention.
2Ease of operation
If no integrated cleaning mechanism is provided, then the device structure remains simple, but the cleaning process becomes difficult and inefficient
Solution Approach 1:
The scraper arm serves multiple functions: it scrapes spent coffee grounds from vertical side walls, scrapes grounds from the base, and deposits grounds into the collection container. This multi-functional design improves ease of cleaning without requiring multiple separate cleaning components or mechanisms.
Solution Approach 2:
The cleaning mechanism is integrated into the brewing filter structure itself. The scraper arm, cleaning members, and collection container are combined into a single unified system that performs both brewing and cleaning functions, eliminating the need for separate manual cleaning tools or procedures.
3Reliability
If spent coffee grounds are not efficiently removed, then the brewing filter can be reused, but hygiene and usability are compromised
Solution Approach 1:
The integrated cleaning mechanism enables the brewing filter to autonomously remove spent coffee grounds after each brewing cycle. By rotating the scraper arm, spent grounds are completely removed from the brewing chamber interior and deposited into the collection container, ensuring hygiene without requiring external cleaning assistance.
