Infusion Chamber Sealing Linkage to Prevent Coffee Pod Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee machines face reliability issues due to incorrect relative positioning between upstream and downstream closing means, leading to jamming and malfunction, which complicates handling and maintenance.
Innovation Solution
A beverage production system with an infusion chamber and a closure device that alternates between two positions, where the upstream and downstream closing means are interdependent, ensuring precise control and operation of the pump and actuator, reducing the risk of jamming and simplifying the mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent control of upstream and downstream closing means is used, then flexibility in operation is improved, but relative positioning accuracy deteriorates leading to jamming and malfunction
Solution Approach 1:
The patent merges the control of upstream and downstream closing means into a single integrated closing device that moves as one unit. This ensures that both closing means maintain precise relative positioning throughout their movement, eliminating positioning errors that would occur with independent control mechanisms.
Solution Approach 2:
The patent introduces a single actuator as an intermediary element that controls both upstream and downstream closing means simultaneously. This actuator serves as a mediator that coordinates the movement of both closing means, ensuring they maintain correct relative positions while still providing operational flexibility through controlled movement between positions.
2Measurement precision
If multiple independent closing mechanisms are used, then control precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple closing functions into a single integrated closing device structure. This unified structure maintains control precision for both upstream and downstream closing operations while reducing the number of separate mechanisms, thereby lowering overall device complexity.
3Manufacturing precision
If complex positioning control systems are implemented, then positioning accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The patent achieves precise positioning through a simple merged structure where upstream and downstream closing means are integrated into one moving unit. This approach eliminates the need for complex positioning control systems, sensors, and actuators, thereby reducing manufacturing costs while maintaining high positioning accuracy.
Solution Approach 2:
The integrated closing device structure is designed to self-maintain correct relative positioning through its inherent mechanical configuration. The structure itself provides the positioning function without requiring additional complex control systems, sensors, or active compensation mechanisms, thereby simplifying manufacturing.

AI summary
The system (10) has a sealing device (60) with an upstream sealing unit (61) to selectively prevent or enable access to packaging (1) in an infusion chamber (7). A downstream sealing unit (62) selectively receives the packaging in the chamber or enables egress of the packaging from the chamber by gravity. The sealing device is arranged such that the position of the upstream sealing unit determines the position of the downstream sealing unit and vice versa. The sealing units are integrated with each other. An independent claim is also included for a method of preparing a beverage by infusing a product in a packaging.
