Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infusion devices face challenges in efficiently removing and compressing insoluble materials like coffee powder or tea leaves, leading to laborious cleaning and potential blockages, especially when large amounts are used, causing uncontrolled water movements and spills.
Innovation Solution
A collecting container with a central projection and coupling elements that create a defined distance between the container edge and piston filter arrangement, allowing for easy coupling with reduced force and preventing excessive compression, thereby minimizing water movement and spills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the press filter is pressed down to compress a large amount of insoluble material, then the coupling between the collecting container and piston filter arrangement is achieved, but excessive force compresses the material blocking the press filter, causing water to flow through the contact surface and create wave-like movements that may spill out
Solution Approach 1:
The patent introduces a collecting container that collects insoluble material before the pressing operation begins. This preliminary collection prevents material from blocking the press filter during compression, allowing the press filter to be pressed down without excessive force while still achieving reliable coupling between the collecting container and piston filter arrangement.
Solution Approach 2:
The system is divided into separate functional components: the collecting container that gathers insoluble material, the press filter that separates liquid from solids, and the piston filter arrangement that provides the pressing force. This segmentation allows each component to perform its specific function efficiently without interfering with others, preventing water from flowing through the contact surface during operation.
2Quantity of substance
If a relatively large amount of insoluble material is used, then the container capacity is sufficient, but the material must be compressed to such an extent that a relatively large force is necessary, blocking the press filter
Solution Approach 1:
The collecting container is positioned to receive and collect insoluble material before the pressing operation. This preliminary collection allows a relatively large amount of material to be accommodated in the container without requiring excessive compression force, as the material is already concentrated in the designated collection area rather than being distributed throughout the entire container volume.
Solution Approach 2:
The collecting container acts as an intermediary structure between the insoluble material and the press filter. It collects and concentrates the material in a controlled manner, facilitating subsequent pressing operations with reduced force requirements while maintaining the ability to handle large quantities of material.
3Stability of the object's composition
If the press filter is slightly biased towards the container, then the coupling is stable, but a correspondingly strong force must be applied to the water to overcome the contact surface, making operation uncomfortable
Solution Approach 1:
The collecting container is introduced into the container before the insoluble material and water, establishing a predetermined coupling interface. This preliminary positioning ensures stable coupling between the collecting container and piston filter arrangement without requiring excessive force to overcome water resistance during the pressing operation.
Solution Approach 2:
The coupling mechanism is extracted from the main pressing operation by using a separate collecting container that couples to the piston filter arrangement. This separation allows the coupling stability to be maintained independently from the pressing force, improving operational comfort by reducing the force needed to maintain coupling during pressing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables effortless coupling of the collecting container with the piston filter arrangement, reducing the force required and preventing uncontrolled water movements and spills, making the infusion process more comfortable and safer.
Implementation Method 1
The press filter is pressed towards the closed end using the piston rod. As a result, the extracted coffee powder or tea leaves are separated from the coffee or tea and compressed in the area of the closed end.
Implementation Method 2
A piston filter arrangement is then introduced into the container, which comprises a piston rod and a press filter attached to the piston rod. The press filter has a shape corresponding to the cross section of the container, so that the press filter ends laterally with the container.
