Device for preparing coffee
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee preparation devices fail to effectively collect and manage residual liquid, leading to contamination issues when the filter vessel is not properly adjusted.
Innovation Solution
A device with a manually operable actuating element on the filter holder allows independent control of closure elements at the drainage openings, enabling users to switch between open and closed positions without moving the entire filter holder, ensuring easy collection of residual liquid and preventing dripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter holder is moved to collect residual liquid, then residual liquid can be collected, but the operation becomes complex and user-friendly control is lost
Solution Approach 1:
The closure element is separated from the filter holder structure, allowing independent control of the drainage opening closure function. This segmentation enables the closure element to be actuated separately from the filter holder position, solving the contradiction between reliable residual liquid collection and ease of operation.
Solution Approach 2:
An actuating element serves as an intermediary between the user and the closure element. This intermediary mechanism translates user input into precise closure element movement, providing intuitive control while ensuring reliable sealing of the drainage opening for residual liquid collection.
2Ease of operation
If a vessel or lid is used to move the closure element, then the closure can be controlled, but the system becomes dependent on vessel placement and more complex
Solution Approach 1:
The closure control function is extracted from the vessel-lid mechanism and integrated directly into the filter holder with a dedicated actuating element. This extraction eliminates the dependency on vessel placement while maintaining ease of operation and reducing overall system complexity.
Solution Approach 2:
The filter holder incorporates its own actuating element for controlling the closure element, making the system self-sufficient. The filter holder can control its own drainage opening closure without requiring external vessel or lid intervention, simplifying the system structure while maintaining operational ease.
3Ease of operation
If the closure element is moved independently of the vessel, then precise control is achieved, but the mechanism becomes more complex
Solution Approach 1:
The actuating element and closure element are integrated into a unified mechanism within the filter holder. This merging reduces the number of separate components and connections needed, simplifying the overall mechanism while maintaining precise control capability for independent closure element movement.

Function Achieved in This Case
This solution allows for efficient collection of residual coffee liquid, reducing contamination risks and simplifying the brewing process by enabling independent control of drainage openings, thus enhancing user convenience and cleanliness.
Implementation Method 1
A spring element can be provided for this purpose, by means of which the closure element is prestressed into the closed position, so that the spring element supports a latching process.
